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

• https://snack.expo.io/SJatzv5aX
• https://github.com/piubellofelipe/num-pad-bug.git

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

No update for this?

No, still facing this issue.

Also, I was able to reproduce it on 0.48.0 when using styled textinput (with color, brackgroundColor, fontSize and width). When not using styled textInput, it doesn't happen in 0.48.0

My next solution is to make a native TextInput component myself, or maybe someone has done it already?
