I m also facing Samsung Galaxy a70 keyboard issue... Keyboard hang sometime and later will not type and backspace also not working sometime.. I think hanging phone that's why it's happening.....
I've just started to experience this. It mainly shows up while using Facebook messenger. I'm using Gboard rather than the Samsung keyboard but the phone is totally up to date so no Samsung have not fixed the issue at least not here in the uk
I'm having problems in my A70 with multi-touch.
I found the problem in PUBG and i wasn't sure it was from the game or the touch itself. So i downloaded multi touch tester and tested the touch screen and found that it was from the touch screen, any fixes?
