Apple has released iOS 10.2.1, which comes about 42 days after iOS 10.2 was released. The description of the update simply says that it includes bug fixes and security improvements for the iPhone or iPad, so it’s easy to tell that this is a minor update. The first iOS 10.2.1 beta was released on December 14th followed by a second beta on December 20th, a third beta on January 9th and a fourth beta on January 12th.

Most likely, this update fixes certain issues that were encountered following the release of iOS 10.2, which included new wallpapers for the iPhone 7 and 7 Plus, a new TV app, new Messages effects, new Camera settings, a new Videos app widget and 100 new emoji characters based on Unicode 9.0.

iOS 10.2.1 says that the software update addresses under-the-hood kernel improvements and bugs that cause Auto Unlock to unlock when the Apple Watch is off the user’s wrist and issues with malicious contact cards that can crash the Contacts app. There is also a fix for an issue that causes an activation-locked device to be manipulated into briefly presenting the Home screen.


Problems after  updating iOS 10.2.1 

Problem no 1: The problem primarily appears to impact iPhone 6 and iPhone 6 Plus owners and logical options such as removing and re-adding fingerprints and a factory reset doesn’t work. From it doesnt seems like the 10.2.1 is better at all.

Problem 2: 

iOS 10.2.1 is causing iPhone displays to dim automatically at specific battery percentages. These are:

  • 74% battery > dim to 70% brightness
  • 49% battery > dim to 50% brightness

Interestingly it appears Apple has done this is on purpose as it has been replicated at these same points by other users.

When the dim happens, the only way to get the normal brightness again is to go to: Settings > Display and Brightness and find the Display Zoom option and tag it to Zoom and then back to normal. This way the brightness is “fixed” until the next time the battery reaches any of the predefined battery percentages.”
