My phone has started randomly restarting. Its happened with a bunch of different apps where it just freezes and craches and restarts. Sometimes several times in a row. I have tried booting into recovery mode to reset the cache but it won't go into that mode (tried with a pc and everything).
Now today it randomly switched my default message app and then later it changed my icon size and home screen layout.
I updated the OS 4 days ago, the day AFTER this initially started.
