iPhone 6 iOS 12.4.3 Problems
We're having a good experience on iOS 12.4.3, but some iPhone 6 and iPhone 6 Plus users have run into bugs and performance issues after transitioning to this version.
The current list includes weird battery drain, issues with Wi-Fi connectivity, problems with Bluetooth, sound problems, various problems with first and third-party apps, Enterprise issues, problems with sound, Touch ID issues, and complaints about random reboots and installation issues.
This list will likely grow as more iPhone 6 and iPhone 6 Plus users move to the firmware.
If you're feeling leery, make sure you keep an eye on feedback about iOS 12.4.3's performance as we push away from the release date.
