This is also a problem reported by many users after upgrading to iOS 16. When typing Vietnamese, the letters and accents are displayed incorrectly, and in some cases, the accents are not displayed at all.

The cause of this problem is still unclear. Currently, you can temporarily fix it by going to Settings > General > Keyboard > Keyboards > Select Vietnamese and try checking AZERTY and QWERTZ below then check QWERTY again at the top.

Alternatively, you can also install Gboard or LabanKey to use instead.

Assistive Touch Hang

Some devices after installing iOS 16 have a problem with Assistive Touch hanging, still working normally and cannot move anymore. The reason may be because the system is being optimized, so some functions will not be stable. Many people said that after restarting the iPhone, Assistive Touch worked normally.

The solution to these problems is to restart your device. Alternatively, with Wi-Fi you can try forgetting the network and then reconnecting from scratch. With Bluetooth devices you can also forget the device and then pair it again.

Device hangs, freezes, battery drains, overheats
