Description
I believe that RN's TextInput has some kind of bug related to "num-pad" or "numeric" keyboard on Android. This bug makes the Android keyboard pretty much unusable after a few minutes of typing straight. Closing the app doesn't help, restarting device does.
Reproducible Demo
Both the snack.expo and the repo are a simple TextInput with autoFocus and keyboardType='num-pad'. I had to type about ~800 characters before keyboard started to lag. At ~2000 it was pretty much unusable.
I tested on a Xiaomi Redmi Note 5, Android 8.1.0 and Gboard (default) as device keyboard
I also believe this could be related to #20119, as I discovered this one while trying to solve #20119
