My samsung Galaxy Core Prime started freezing a few days ago for no reason. I turn my phone on and it works perfectly fine for about 2 minutes and then it just freezes. Sometimes it works fine for longer but whenever I connect to WIFI it seems to freeze quicker. Everytime it freezes I have to take the battery out of the phone for about a minute otherwise it wont turn on.

Is there a way where I can find out what exactly is wrong with my phone (a corrupt file, app, update...). Also, is there a way where I can transfer everything on my phone to my laptop incase I have to factory reset my phone. The thing i'm confused about is that my phone works perfectly and then suddenly freezes, so im not sure if factory resetting my phone will work because it may be someting to do with the sofware.
You can use Smart Switch to backup your data to your laptop.
A data backup and factory reset is the last resort tech support will use to resolve software issues before advising a repair.
Also, it may be worth trying it in Safe Mode for a bit, as it runs the phone with only the stock apps, and so is a good way to see if a non-stock app is the cause of the issue.
