The iOS mobile operating system developed by Apple Inc. has had a wide range of bugs and security issues discovered throughout its lifespan, ranging from security exploits discovered in most versions of the operating system related to the practice of jailbreaking, as well as bypassing the user's lock screen (known as lock screen bypasses), to issues relating to battery drain, to crash bugs encountered when sending photos or certain Unicode characters via text messages sent through the Messages application, and general bugs and security issues later fixed in newer versions of the operating system.

Below here are the problems related to iOS

iOS 4[edit]

Performance and battery issues[edit]

iPhone 3G users reported performance and battery issues after upgrading to iOS 4. Apple started an investigation of the matter in July 2010. In November, Apple was sued for the issues, with an unsatisfied customer alleging "violating the Consumer Legal Remedies Act, unfair business practices, and false and deceptive advertising", with further allegations that Apple knew its software would cause problems on older models. Apple never responded to the allegations, but wrote in a reply to another unsatisfied customer in August 2010 that updates were "coming soon".[1]

Alarm clock[edit]

The Alarm feature of the built in Clock app in the iPhone and iPod Touch has been plagued by major bugs in all versions of iOS 4. The first bug noticed was the "DST bug" which was first seen when some countries switched to/from daylight saving time from/to standard time in October or November 2010[2][3]. It caused recurring alarms to start going off an hour too early or late. Apple promised the bug would be fixed in iOS 4.2, but according to some reports it still exists even in iOS 4.3.1.[4]

The second alarm clock bug discovered was the "New Year's Day bug" which showed up on January 1, 2011 and January 1, 2012. It caused non-recurring alarms to never work.[5] However, two days after each New Year's Day, on January 3, 2011, they "magically" started working again. This bug was seemingly fixed in iOS 4.3.

Antenna problems[edit]

Upon its release, some iPhone 4 users reported having technical problems with the phone's antennas[6]. Apple attempted to fix the issue with iOS 4.0.1,[7] but failed to do so.[8]

iOS 5[edit]

Initial upgrade issues[edit]

The initial October 2011 release of iOS 5 saw significant upgrade issues, with errors during installation and Apple server overload.[9][10][11]

iPhone 4S battery life[edit]

Following user complaints, Apple officially confirmed that iOS 5 had poor battery life for some iPhone 4S users, and stated that an upcoming software update would fix the issues.[12][13] The iOS 5.0.1 update fixed bugs related to battery issues.[14]

Wi-Fi connectivity drops[edit]

In November 2011, Engadget reported that the iOS 5 update caused Wi-Fi connection drops for some users. The report also wrote that "The recent iOS 5.0.1 update certainly hasn't fixed the matter, either", and questioned whether the events were unrelated or part of a larger issue.[15]

SIM card failure[edit]

Some iPhone 4S users reported issues with the SIM card in iOS 5, being given error messages about "Invalid SIM" and "SIM Failure".[16] Apple released a second software build of the 5.0.1 update designed to fix SIM card issues.[17]

Phone call echo[edit]

Some iPhone 4S users reported the random appearance of echoes during phone calls made with earphones in the initial release of iOS 5. The other party in the call was sometimes unable to hear the conversation due to this problem.[18][19]

iOS 6[edit]

Maps app launch[edit]

In iOS 6, Apple replaced Google Maps with its own Apple Maps as the default mapping service for the operating system, and immediately faced criticism for inaccurate or incomplete data, including a museum in a river, missing towns, satellite images obscured by clouds, missing local places, and more.[20][21][22]

Apple CEO Tim Cook issued a letter on Apple's website apologizing for the "frustration caused by the Maps application,"[23] and recommended downloading alternative map apps from the App Store.[24][25] Scott Forstall, the then-VP of iOS software engineering, was involuntarily dismissed from his role at Apple in October 2012 after he "refused to sign his name to a letter apologizing for shortcomings in Apple's new mapping service."[26]

Advertising Identifier privacy skepticism[edit]

In September 2012, Sarah Downey, a "privacy expert" with the software company Abine expressed her concern that in spite of the new "Advertising Identifier," Apple didn't disclose details on what the identifier was actually based on. She stated: "I need them to tell me why it's not identifying because as we've seen from a lot other "non-identifying" pieces of data, they can identify you quite easily," and that "If you're using the opt-out, [Apple] may no longer gather information to serve you targeted ads. To me, that says they may still collect your information to do things other than serve you targeted ads, like build databases about you to send you marketing or to sell to third parties."[27]

Abnormal data usage[edit]

Many users reported a higher-than-normal data usage after upgrading to iOS 6, causing some to be heavily billed for data largely exceeding their data plan. Steve Rosenbaum of The Huffington Post wrote that "The bug is the result of an iOS 6 problem that connects the phone to the cellular data network whenever the phone is connected to a WiFi signal," and also stated that Apple had released a patch.[28][29]

FaceTime certificate expiration[edit]

In April 2014, users who were still running iOS 6 could not connect to FaceTime due to the expiration of a certificate. Apple released a support document explaining the problem, adding that devices capable of upgrading to iOS 7 must do so to fix the issue, while devices stuck on iOS 6, the iPhone 3GS and the iPod touch (4th generation), would receive an iOS 6.1.6 update.[30]

Bluetooth[edit]

Many users report a problem with Bluetooth audio streaming to a range of compatible devices. The sound cuts out every now and then for no apparent reason. As of October 2012, no solution has been provided by Apple.[31]

Location-based Reminders[edit]

Location-based reminders do not work for iPads, even though they were promised to work on cellular enabled devices.[32] It has later been clarified by Apple that only the 4th generation iPad and the iPad Mini 1st generation or later will be able to use this.[33]

Cellular Network[edit]

In iOS 6.1, users reported problems with cellular connectivity. This was addressed for the iPhone 4S in iOS 6.1.1 which "fixes an issue that could impact cellular performance and reliability for iPhone 4S."[34]

Do Not Disturb[edit]

Many iPhone users experienced a bug with the Do Not Disturb feature when the calendar changed from 2012 to 2013. The feature would be left on past the scheduled time set by the user, allowing texts, notifications, and alarm settings to be missed. The bug was caused by a difference in formatting in the ISO calendar system versus the Gregorian calendar system.[35] Apple did not offer a quick software update for the bug, instead saying that the bug would fix itself on January 7, 2013.[36]

Microsoft Exchange[edit]

Another bug causes issues when iOS devices connect to a Microsoft Exchange server to retrieve email, resulting in message "mailbox server resources are consumed, log growth becomes excessive, memory and CPU use may increase significantly, and server performance is affected".[37] Microsoft have suggested several workarounds,[38] and Apple responded with a KnowledgeBase article describing the cause of the bug and a suggested temporary workaround, promising a fix in the near future,[39] which was then fixed with release of iOS 6.1.2.

Lockscreen bypass code[edit]

On iPhones, another bug found in iOS 6.1 allowing bypassing the lock screen's passcode to temporarily gain full access to the Phone app, by performing a specific sequence of actions on the phone that remained unfixed,[40] with Apple acknowledging the bug[41] and then addressed with release of iOS 6.1.3.

Audio profile speakerphone[edit]

iPhone 5 users experienced dropped calls during the release of iOS 6.1.3 when there was an issue with the audio microphone profile. This also caused issues with many voice-over commands, including Siri, to get different results than expected or to fail easily. Apple fixed this bug with the release of iOS 6.1.4, which updated the audio speaker profile so users would get better results.

Data security[edit]

An attacker can collect or modify data in sessions protected by SSL/TLS protocols. This same bug was also reported on iOS 7.0.4 and iOS 7.0.5 for the iPhone 5C and 5S. For the iPhone 3GS and the iPod Touch (4th generation), iOS 6.1.6, which is the final version supported for iPhone 3GS and iPod touch (4th generation), was released to fix this issue since iOS 7 is not compatible with these devices. (see iOS 7.x)

iOS 7[edit]

Design causing sickness[edit]

In September 2013, Pranav Dixit of Fast Company reported about user complaints shared on Apple's support forums that the new design of iOS 7, including "many zoom animations while multitasking and opening and closing apps, in addition to a slight parallax effect" were causing users to feel sick. Dixit noted that while the parallax effect could be turned off, most animations did not have such an option.[42]

Dr. George Kikano, "division chief of family medicine at UH Case Medical Center in Ohio," told Fox News that "There's some validity to this, for people who are susceptible." Fox News wrote that Dr. Kikano said "It's a new "parallax" function that causes the background of the phone to subtly move back and forth, a feature that leads to an effect not unlike car sickness. The inner ear is responsible for balance, the eyes for vision. When things are out of sync you feel dizzy, nauseous. Some people get it, some people don't, and some people get used to it."[43]

Battery drain[edit]

Adrian Kingsley-Hughes of ZDNet wrote in March 2014 that iPhone and iPad users reported battery drain with the iOS 7.1 update.[44] In lab testing, Andrew Cunningham of Ars Technica found some hardware models experienced minor battery depletion, while others experienced no statistically significant changes.[45]

Lock screen bypass[edit]

Dom Esposito of 9to5Mac reported in June 2014 that a new lock screen bypass method had been discovered in iOS 7, allowing access to the phone in "5 seconds under certain circumstances". The issue was later fixed.[46]

Creation of CardDAV Accounts not working[edit]

Creating a CardDAV Account contains a bug that needs manual fixing of the CardDAV-Server-URL.[47]

Safari ignores local domain[edit]

Local domain names can no longer be resolved in Safari.[48][49] This breaks short names on the local network.

Home screen crashes[edit]

Users have reported various crashes of the home screen, the core service that renders the home screen icons, Notification Center, Control Center, Siri and the lockscreen.[50] This was fixed in iOS 7.1.

Data security[edit]

.[51]

Battery Indicator stuck until restart[edit]

iPhone 4S users report experiencing problems with the battery indicator; the indicator will freeze at the same value until the iPhone is restarted again.[52][53]

Touch ID[edit]

In iOS 7.1, Touch ID was not functioning on the iPhone 5S. The problem cannot be resolved by turning Touch ID on and off in the "Fingerprint and Passcode" menu, restarting, resetting, or restoring the device using iTunes.[54] This issue was fixed in iOS 7.1.1.[55]

iOS 8[edit]

App crash rate[edit]

A study by Apteligent (formerly Crittercism) found that the rate at which apps crashed in their tests was 3.56% on iOS 8, higher than the 2% found on iOS 7.1.[56]

HealthKit[edit]

Shortly after the release of iOS 8, Apple released a statement pointing out that a bug had been found in the operating system which prevented HealthKit-compatible apps from being released alongside iOS 8.[57] Apps already released that included HealthKit functionality were withdrawn from the App Store. iOS 8.0.1/8.0.2 included a fix for this issue.

8.0.1 update issues[edit]

In September 2014, the iOS 8.0.1 update caused significant issues with Touch ID on iPhone 6 and cellular network connectivity on some models. Apple stated that affected users should reinstall the initial iOS 8 release until version 8.0.2 was ready.[58][59][60]

Meanwhile, some of the HealthKit compatible apps won't be available on the App Store until iOS 8.0.2 is released to fix these issues.

iOS 8.0.2 was released one day after 8.0.1, with a fix for issues caused by the 8.0.1 update.[61]

Miscellaneous bugs[edit]

Forbes published several articles focusing on problems in iOS 8 regarding Wi-Fi and battery,[62] Bluetooth,[63] and calendar.[64]

"Effective power" text message crash[edit]

In May 2015, news outlets reported on a bug where receiving a text message with a specific combination of symbols and Arabic characters, caused the Messages application to crash and the iPhone to reboot.[65][66][67]

The bug, named "effective power,"[68][69] could potentially continuously reboot a device if the message was visible on the lock screen.[70]

The flaw was exploited for the purpose of trolling, by intentionally causing others' phones to crash.[71]

The bug was fixed in iOS 8.4, an update released in June 2015.[72]

Touch ID[edit]

Users who updated phones with Touch ID enabled to iOS 8.3 found out that they could not use Touch ID to make App Store purchases.[73] A workaround has been devised by users to repair this issue.[74]

Performance[edit]

Many users of older generation devices such as the iPhone 4S and the iPad 2 reported performance issues with iOS 8. Apple has since released iOS 8.1.1 in attempt to fix the problem.[75]

Keyboard[edit]

Several issues with the new Keyboard API in iOS 8 were reported, including problems with custom keyboards crashing or not appearing, or being replaced with the default keyboard.[citation needed] Apple has since released iOS 8.3 in attempt to fix the problem.

iOS 9[edit]

Error 53 bricking issue[edit]

In February 2016, news outlets reported that users who updated to iOS 9 on a particular device that had components repaired by a third-party (notably the Touch ID fingerprint recognition sensor) rendered their phone unusable. The issue, named "Error 53",[76][77] was, according to iFixIt, limited to iPhone 6 and 6 Plus devices.[78] Apple stated:[79]

We protect fingerprint data using a secure enclave, which is uniquely paired to the Touch ID sensor. When iPhone is serviced by an authorised Apple service provider or Apple retail store for changes that affect the Touch ID sensor, the pairing is re-validated. ... This check ensures the device and the iOS features related to Touch ID remain secure. Without this unique pairing, a malicious Touch ID sensor could be substituted, thereby gaining access to the secure enclave. When iOS detects that the pairing fails, Touch ID, including Apple Pay, is disabled so the device remains secure.

Apple released a new version of iOS 9.2.1 (9.2.1.1) later in February to fix the issue.[80]

Date reboot issue[edit]

In February 2016, a bug was discovered that could render 64-bit devices unusable. The bug, caused by setting the time to January 1, 1970, would cause the device to get stuck in a reboot process until the battery died or the time setting shifted past January 1. A similar bug also applies to 32-bit devices, where the battery would report 0% of charge, and the Wi-Fi would be disabled.[81] iOS 9.3, released on March 21, 2016 and 9.7-inch iPad Pro initial release, fixed the issue.[82]

9.7-inch iPad Pro bricking issue[edit]

In May 2016, Apple released iOS 9.3.2. The update was followed by reports that it bricked some 9.7-inch iPad Pros, with a "Connect to iTunes" message, and an "Error 56" message in iTunes that it couldn't restore the tablet.[83][84]

As a result, Apple temporarily stopped offered iOS 9.3.2 for 9.7-inch iPad Pros. The re-released build of iOS 9.3.2 was released in June 2016 as version 9.3.2.1 fixed the issue.[85]

iBooks crash[edit]

The release of iOS 9.3.3 in July 2016 was followed by reports that the iBooks store crashed.[86] However, Apple explained in August that the timing was a coincidence, and the iBooks app crash was a result of a server issue, not the software update.[87]

Spyware attack[edit]

The release of iOS 9.3.5 in August 2016 fixed three critical security vulnerabilities. The vulnerabilities could be exploited to silently enable a jailbreak and allow the malicious installation of a spyware called "Pegasus". Pegasus could intercept and read text messages, emails, track calls, trace phone location, activate the microphone, and gather information from apps, including (but not limited to) iMessage, Gmail, Viber, Facebook, WhatsApp, Telegram, and Skype.[88]

The discovery of the vulnerabilities dated 10 days before the 9.3.5 update was released. Arab human rights defender Ahmed Mansoor received a suspicious text message with a link and sent it to Citizen Lab. An investigation ensued with collaboration from Lookout that revealed that if Mansoor clicked the link, it would have jailbroken his phone and implanted it with the spyware. Citizen Lab linked the attack to an Israeli surveillance company known as NSO Group that sells Pegasus to governments for "lawful interception."[89][90]

Regarding how widespread the issue was, Lookout explained in a blog post: "We believe that this spyware has been in the wild for a significant amount of time based on some of the indicators within the code" and pointed out that the code shows signs of a "kernel mapping table that has values all the way back to iOS 7."[91]

News of the spyware received significant media attention,[92][93][94][95][96] particularly for being called the "most sophisticated" smartphone attack ever,[97][98] and for being the first time in iPhone history that a remote jailbreak exploit has been detected.[99]

"Broadpwn" Wi-Fi vulnerability[edit]

In July 2017, information on a critical Wi-Fi security vulnerability affecting 1 billion iOS and Android devices was published. The issue, named "Broadpwn", allows an attacker to remotely take control of nearby vulnerable devices and turn affected devices into "rogue access points", further spreading the infection to other nearby devices.[100] Apple released a security patch for the issue as part of its iOS 10.3.3 update,[101] though older devices running iOS 9, including the iPad 2, 3rd generation iPad, iPhone 4S, the first-generation iPad Mini, and the 5th generation iPod Touch were left without an available update, causing concerns over the safety of the iPad 2, 3rd generation iPad, and the first-generation iPad Mini in schools.[102]

iPhone 4S lawsuit[edit]

On December 22, 2015, Apple faced a class-action lawsuit for crippling the iPhone 4S with the iOS 9 update, with some people even going so far as to say that iOS 9 rendered their devices unusable.[103][104] The 4S only had 512MB of RAM,[105] so it could not handle the iOS 9 update.

Bluetooth[edit]

Many iPhone SE owners experienced various issues relating to phone calls via Bluetooth connectivity.[106] This issue was fixed with iOS 9.3.2.

Security[edit]

A WebKit rendering component exploit was discovered that threatened users' security by allowing access to device sensors was discovered with the release of 9.3.3. The exploit worked by tricking the user to click on a URL contained in an SMS.[107] This was quickly fixed with the release of 9.3.5.

iOS 10[edit]

Recovery mode issues[edit]

The initial public release of iOS 10 on September 13, 2016 saw many iPhones and iPads sent into recovery mode, by the over-the-air update, requiring devices to be connected to a Mac or PC with iTunes in order to retry the update or restore the device to factory settings.

As a result, the initial release of iOS 10 was pre-installed only on iPhone 7 and iPhone 7 Plus.

Apple shortly after released iOS 10.0.1, and issued an apology.[108]

Local backup encryption issue[edit]

In September 2016, it was discovered that the encryption of local iOS backups made with iTunes is weaker for iOS 10 devices than for devices running iOS 9. Russian software firm ElcomSoft discovered that the iOS 10 backup process skips several security checks, making it "approximately 2,500 times" faster to try passwords, enabling 6 million password tries per second compared to the 2,400 password tries per second for the same process ElcomSoft has used on iOS 9. The firm stated that the impact is "severe".[109] Apple acknowledged the problem, said it planned to issue a security update, but also stated that iCloud backups were not affected.[110] The iOS 10.1 update subsequently fixed the issue.[111]

Battery shutdowns and throttling[edit]

Some iOS 10.1.1 users reported that their devices were prone to unexpectedly shutting down at or around 30% battery charge (with one user describing the battery percentage as dropping unexpectedly from 30% to 1% before doing so, but still registering as 30% when plugging it in to charge it).[112][113] Apple began the process of diagnosing this bug in iOS 10.2, and stated following the release of iOS 10.2.1 that it had reduced the occurrence of these shutdowns by "more than 80%" on iPhone 6S models and "over 70%" on iPhone 6 models. It also became possible to reboot the device after an unexpected shutdown without plugging it into power.[114][115]

In December 2017, speculation emerged that Apple had been intentionally throttling the performance of older iPhone models based on battery health, especially on the iPhone 6S (which, in a separate issue, also had isolated incidents of a battery manufacturing issue that was also causing system instability),[116][117] after a user benchmark showed a variance in performance after a battery replacement.[118] The developers of Geekbench confirmed that there had been sizable decreases on benchmark scores on iPhone 6 devices running iOS 10.2.1 and later, and iPhone 7 devices since iOS 11.2 and later. These led to concerns that Apple was instituting planned obsolescence policies in order to encourage sales of newer iPhone models, a controversy dubbed Batterygate.[119]

Later that month, Apple admitted that since iOS 10.2.1, it had been implementing performance management techniques on older iPhone models to preserve system stability, especially in situations where their batteries are "less capable of supplying peak current demands," such as cold weather, age, or low charge. Apple stated that these measures were intended to help "deliver the best experience for customers, which includes overall performance and prolonging the life of their devices."[120] The company announced that it would offer a discount on out-of-warranty battery replacements during 2018.[121]

iOS 11[edit]

Wi-Fi and Bluetooth Control Center toggles[edit]

Shortly after iOS 11 was released, Vice's Motherboard discovered new behaviors by the Wi-Fi and Bluetooth toggles in the Control Center. When users tap to turn off the features, iOS 11 only disconnects the chips from active connections, but does not disable the respective chips in the device. The report further states that "it's a feature, not a bug", referencing documentation pages by Apple confirming the new toggle behaviors as a means to disconnect from connections but remain active for AirDrop transfers, AirPlay streaming, Apple Pencil input, handoff and other features. Security researcher Andrea Barisani told Motherboard that the new user interface was "not obvious at all", making the user experience "more uncomfortable".[122][123] In October 2017, the Electronic Frontier Foundation published an article, calling the interface "misleading" and "bad for user security", due to a higher risk of security vulnerabilities with Wi-Fi and Bluetooth chips activated while not in active use. The Foundation recommended that Apple fix the "loophole in connectivity", writing that "It's simply a question of communicating better to users, and giving them control and clarity when they want their settings off - not "off-ish"".[124][125]

iOS 11.2 changes this behavior slightly, by turning the toggles white and showing a warning message that explains the functions of the toggles in the Control Center, when the toggles are turned off.[126]

Battery drain issues[edit]

Some users have experienced battery drain problems after updating to iOS 11. In a poll on its website, 70% of 9to5Mac visitors reported decreased battery life after updating to the new operating system.[127] However, in an article featuring Twitter complaints of battery life, Daily Express wrote that "honestly, this is to be expected. It happens every year, and it's completely normal. Major iOS releases will hammer the battery on your device much faster during the first few days of use",[128] with Forbes stating in an article that "The days after you install a new version of iOS, your iDevice is busy doing all sorts of housekeeping. Practically all of your apps have updates, so iOS is busy downloading and installing them in the background. [...] Additionally, after you install a new version of iOS, it has to do something called "re-indexing." During this process, iOS 11 will comb through all of the data on your device so that it can be cataloged for quick Spotlight searching." The article further states that "The good news is that both of these things are temporary".[129]

Within a week of the launch of the 11.3.1 update, users began reporting continued issues with this update regarding battery drainage. Some of these reports indicated drains from 57% down to 3% in just 3 minutes. Even users with the health of the battery measuring 96% noticed iPhones draining at around 1% per minute. In addition to battery drains, some iPhone users noticed their devices having excessive heat buildup.[130]

It has been recommended by technology experts that users not upgrade their software until the release of a version subsequent to 11.3.1 unless specifically plagued by the 'third party display issue'.[130]

Calculator bug[edit]

In October 2017, users reported on Reddit that quickly typing in an equation in the built-in iOS calculator app gives incorrect answers, most notably making the query "1+2+3" result in "24" rather than "6". Analysts have blamed an animation lag caused during the redesign of the app in iOS 11. The problem can be worked around by typing the numbers slowly, or by downloading alternative calculator apps from the App Store that do not have this problem. With a large amount of bug reports filed, Apple employee Chris Espinosa indicated on Twitter that the company was aware of the issue.[131] iOS 11.2 fixed the issue.[126]

Keyboard autocorrect bugs[edit]

In November 2017, users reported a bug in the default iOS keyboard, in which pressing "I" resulted in the system rendering the text as "!" or "A" along with an incomprehensible symbol featuring a question mark in a box. The symbol is known as Variation Selector 16 for its intended purpose of merging two characters into an emoji.[132] Apple acknowledged the issue in a support document, advising users to set up a Text Replacement feature in their device's keyboard settings as a temporary workaround.[133] The company confirmed to The Wall Street Journal that devices using older iOS 11 versions, as opposed to just the latest 11.1 version at the time of the publication, were affected by the issue, and an Apple spokesperson announced that "A fix will be released very soon".[134] iOS 11.1.1 was released on November 9, 2017, fixing the issue.[135]

At the end of the month, another keyboard autocorrection bug was reported, this time replacing the word "It" with "I.T." MacRumors suggested users set up the Text Replacement feature the same way they did for the earlier autocorrection issue, though its report notes that "some users insist this solution does not solve the problem".[136] It was fixed with the release of iOS 11.2.[137]

December 2 crashes[edit]

In early December, users wrote on Twitter and Reddit that, at exactly 12:15 a.m. local time on December 2, any App Store app that sends local notifications would cause the device to repeatedly restart. Reddit users reported that disabling notifications or turning off background app refresh would stop the issue, while Apple staff on Twitter reported that it was a bug in date handling, recommending users to manually set the date prior to December 2. MacRumors wrote that the issue "looks like it's limited to devices running iOS 11.1.2", with users on the 11.2 beta release not affected.[138][139] Apple responded by releasing iOS 11.2 early to fix the issue.[126]

iOS 11.2 HomeKit vulnerability[edit]

In December 2017, 9to5Mac uncovered a security vulnerability in iOS 11.2 within Apple's HomeKit smart home system, allowing unauthorized access to smart locks and garage door openers. It noted that Apple had already issued a server-side fix that, while preventing unauthorized access, also limited HomeKit functionality, with an upcoming software fix for the iOS operating system intended to restore the lost functionality.[140][141] On December 13, 2017, Apple released iOS 11.2.1, which fixed the limitation on remote access.[142]

Mail[edit]

Users with Outlook.com, Office 365, and certain Exchange accounts were unable to send email.[143] This has been resolved with the release of iOS 11.0.1, along with the release of iPhone X.[144]

Telugu character crash[edit]

A bug was present in iOS 10 and 11 that would cause an app to crash when a certain sequence of Telugu characters was pasted into it, or for the phone's home screen if pasted into Spotlight search. The bug was fixed with iOS 11.2.6.[145]

iPhone 8 touchscreen issues after third-party repair[edit]

The iOS 11.3 update caused some iPhone 8 devices that had had their screens repaired by a third party repair shop to become unusable by disabling the touch screen. Apple corrected this issue by releasing iOS 11.3.1.[146]

iOS 12[edit]

Rainbow flag emoji[edit]

After a rainbow flag emoji with an interdictory sign over it appeared on Twitter, several users accused Apple of encouraging anti-LGBT attitudes. However, Emojipedia has clarified that this occurs when a user tweets the two emojis together and is not an intended feature. This can be used with other emojis as well.[147][148][149]

FaceTime eavesdropping issue[edit]

A FaceTime issue impacting several versions of iOS 12 (versions 12.1–12.1.3) allowed users to call someone via FaceTime and hear the audio coming from their phone before answering the call,[150] before the bug was fixed in iOS 12.1.4.[151]

Sending iMessages to the wrong contacts[edit]

iOS 12 merges conversation history for devices using a shared Apple ID, even if separate handles are used, such as unique phone numbers or email addresses. As a result, iMessages may be delivered to the wrong device.[152]

iOS 12.3.2 update incompatibility[edit]

The iOS 12.3.2 update, released for iPhone 8 Plus devices only, caused users to be unable to transfer backups for this version to a different iPhone model as only the 8 Plus has this software update.[153]

iOS 12.4 jailbreak[edit]

A kernel vulnerability that was fixed in iOS 12.3 was accidentally restored in iOS 12.4. This made iOS 12.4 vulnerable to exploits using the vulnerability, and a jailbreak was released.[154] Later, the kernel vulnerability was patched again by Apple in iOS 12.4.1.[155]

iOS 13[edit]

Memory management issue[edit]

After the release of iOS 13.2, reports followed about applications being cleared from memory at a higher rate than in iOS 13.1, including on the then latest iPhone models.[156] Apple attempted to fix the issue twice in iOS 13.2.2[157] and iOS 13.3.[158]

iOS 13.5 jailbreak[edit]

A jailbreak software called Unc0ver was updated in May 2020 with an exploit targeting devices running iOS 11 and above, including the then-latest iOS 13.5. The issue was fixed with iOS 13.5.1.[159]

iOS 14[edit]

Missing keyboard for Spotlight search[edit]

The keyboard did not appear when using the Spotlight search function.[160]

Default app setting reset[edit]

The ability to change the default app for messages, email, internet or other services is reset to the stock app every time the device is reset or turned off.[161] Apple attempted to fix the issue with iOS 14.0.1.[162]

General battery drain[edit]

On 30 September 2020, Apple acknowledged a battery drain issue in iOS 14 and released a supporting document that offered the users tricks to fix the poor battery performance. In this document Apple claimed that unpairing the iPhone from an Apple Watch followed by erasing all data and settings of the iPhone, and restoring from a backup could be a possible fix for the battery life.[163]
