I think its just old and been through a lot. Its been in -45c to +56c weather multiple times. Rained on, sweat and tons of things removed and added onto it.

I sometimes cant even use maps and music together in my car or it will just restart

My daily phone. Its getting a little slow now though

Ive had this issue as well. I find it happens when i leave my wifi and go to cell signal. Not sure if its the same for you. I dont think ive had it be almost a week later but its been a few hours or maybe a day

My brother

Wamp anyone? (I think thats what its called, im at work and cant check my pc) Or am i the odd one out.
