(Note 10+)
When I open an unread text & reply, the keyboard comes up and then when I start typing it will drop down (disappear) and the small white text box will be at the bottom and I will have to touch where the cursor has stopped and start typing. Never did this before. Usually I could just start replying in the message and my keyboard wouldn't drop down and I could just send after I was done.
Also sometimes when typing a text the screen will jump/flick when I touch a few letters then stop. It's not continuous but sporadic. None of this ever happened before the last phone update. Any solutions?
