iOS 11 Plagued with Untested Bugs and Early Adoption Pitfalls


iOS 11 was released just a day ago and some early adopters have already started complaining of inherent bugs in Apple's new software. It is now being reported that the majority of users have resorted not to upgrade to iOS 11 even on supported devices, fearing potential problems that include untested bugs and early adoption pitfalls.

According to recent report from Mixpanel, iOS 11 is currently installed on just over 10 percent of supported devices since the software was launched. iOS 11 adoption rate pales out in comparison to iOS 10 adoption rate which stood at 14 percent after 24 hours from its launch.

Veteran iOS users have wisely held off installing major new iOS releases until a couple of new updates are rolled out and others have learnt from their past mistakes about the pitfalls of early adoption with any new iOS release.

With so much at stake for the end user, let us explore the potential pitfalls and inherent bugs in iOS 11 on both iPhones and iPads.

Disabling Bluetooth and Wi-Fi in the Control Center

iOS 11 no longer supports the traditional simplicity of disabling Bluetooth with a single tap in Control Center. In other words, disabling Bluetooth from Control center will only disconnect the active Bluetooth pairings and prevents new pairings until the option is re-enabled. Wi-Fi seems to be having a similar drawback in iOS 11.

According to the recent support document published on Apple website, the Wi-Fi and Bluetooth toggle feature fails to disable certain radio features like AirDrop, AirPlay, Handoff, Instant Hotspot, Apple Pencil, Apple Watch, and Location Services. Consequently, this could lead to major battery drain and wastage of resources on the device as some Bluetooth and Wi-Fi processes or services continue to run in the background.

Inability to Send Outlook, Exchange and Office 365 e-mails

 Several iOS 11 users who are still using e-mail accounts hosted on, Office 365, or Exchange Server 2016 are reportedly encountering an error message saying, "Cannot Send Mail. The message was rejected by the server."

Meanwhile, both Microsoft and Apple have acknowledged the issue and have promised a fix in the upcoming iOS update. As a workaround, Microsoft has suggested switching to its standalone Outlook mail app for iOS.

Users must note that iOS 11 has a few limitations with the Bluetooth and Wi-Fi functionality in Control Center. As iDownloadBlog reports, here are a few such scenarios wherein Auto-Join feature for Wi-Fi will also get disabled when Wi-Fi is turned off or when the Wi-Fi icon is dimmed in the Control Center:

• You turn on Wi-Fi in Control Center
• You manually connect to a Wi-Fi network in Settings → Wi-Fi
• You walk or drive to a new location
• It’s 5am local time
• You restart your device

Along similar lines, whenever Bluetooth is turned off in Control Center, you will no longer be able to pair the device to any Bluetooth accessories until:

• You turn on Bluetooth in Control Center
• You connect to a Bluetooth accessory in Settings → Bluetooth
• It’s 5am local time
• You restart your device
