I didn't want to have to reinstall everything and potentially lose data, etc. However, it doesn't matter because the phone bricked (completely dead) in my pocket 2 days ago and I've purchased a new phone. I don't know if the sensors problem was a symptom of the phone going to die, or if something else killed it.
