I've had my note 4 for about 4 months now with no problems. Last night it kept freezing and no buttons were responsive so I took the battery out and rebooted...I did this a few times last night and this morning but it didn't work. I read I should wipe the cache partition which ive also done but the problem hasn't stopped! Does anyone know what I can do? I ideally don't want to reset the phone for obvious reasons.
