I don't really know how to explain this, but I will go ahead and try. I got my S21 in January 2021 and then needed a replacement due to another issue and both phones did the same thing...
When pressing "backspace" within the app to cancel what I've written, it kind of jumps back and deletes more than it should do, and changes words to something else. Not every time, but most of the time.
I can get this on a screen recording if needs be and upload to YouTube because I don't know if anyone will understand what I mean.
If this happens to you, you'll probably know what I mean but has anyone solved this buggy issue? As I said, two different s21s did the same thing and it's been a problem for over a year. Thanks.
