Apple iPhone SE
The iPhone SE was facing some audio related issues which has been addressed in the latest iOS update IBTimes UK

Apple has released the iOS 9.3.2 update bringing minor improvements and bug fixes for all iPhone, iPad, and iPod touch models that support iOS 9. The latest software update was released by the company after four beta tests which carried out various improvements and fixes.

The update which weighs roughly 89.4MB in size largely brings improvements as listed by the developer especially to the iPhone SE, some of whose users complained of "audio quality issues" when paired to Bluetooth headsets. The update also restores the simultaneous functioning of the Low Power mode and Night Shift Mode which it had tested in the various beta rollouts a few weeks back.

In addition, an issue with dictionary definitions where the app froze more often than not has been fixed. Another problem of users being prevented from typing email addresses when using the Japanese Kana keyboard in Mail and Messages has been fixed. Apple has also fixed the issue that prevented MDM servers from installing custom B2B apps.

While most devices are getting to experience the fixes and improvement some 9.7-inch iPad Pro owners have complained of their device being struck by the "Error 56" issue. MacRumors reports that users have been complaining post their iOS 9.3.2 update of the issue which Apple's error code support document defines as a hardware issue.

As per Apple, if users do face this issue they will need to install the latest version of iTunes and also check for issues with third-party security software. We recommend that until Apple comes out with a full-fledged solution to this problem, those with the 9.7-inch iPad Pro should refrain from updating their device to iOS 9.3.2.
