My phone keeps going all rainbow, pink or fuzzy and come okey shuts down then starts again why is this happening and is it going to break fully

Sounds to me like you may have dropped it hard enough to cause damage to the board. The logic boards in these phones is actually two boards sandwiched on top of each other. You’re gonna want to look for a specialist in board repair. There’s companies like STS Telecom and iPad Rehab, both of which are excellent repair shops. They both have youtube channels if you want to check them out.

I could also have a damaged screen, you might have a repair shop try a screen and see if that fixes it. When it’s on does it ring and give audible noise/notifications? Even when the screen is black or acting funny?
