So my Galaxy S3 has been running slow, overheating and shutting down, etc. I have the Clean Master cleaning app that clears all my cache, RAM and cools it down but the problems are reoccurring. I have an excessive about of text messages so I thought this could be the source of the problem. I normally use SMS Go Pro messaging and when I selected multiple threads to delete, it just said (DELETING 0/191) with a percent bar but never deleted any threads and then the app failed. So I tried to do it from my default messaging app and that won't even open (Messaging Isn't Responding. Would you like to close it?) I got it to respond once and tried to delete a single thread but the app keeps closing. I tried to delete just one thread with Go Pro also and it also said (Go Pro Isn't Responding, etc.). Does anyone have any ideas of whats going on?
