My iPhone 8+ was dropped several times to the point where pieces of the top part of the screen were falling and it has cracks mostly towards the top half of the screen then there is to the bottom half. It has gotten worse when I’ve tried to use my phone, the top half of the screen wouldn’t work when I touched it but the bottom half where the keyboard was located did. The last time I dropped my phone, it would move from different apps on its own and use the keyboard on its own. It would call contacts on my phone and it almost dialed emergency contacts such as 911. It recently has also not let me enter my password and locks me out from 5mins to an hour. I don’t know whether repairing/ changing the screen would stop this continuation.
