Samsung Galaxy S3 Freezing all the time
So, I have a 2 year old SIII, I think Android 4.4. Never had any issues using it, but since last weekend it started freezing like crazy. The screen just freezes out of nowhere, the screen dont even fade. Then I have to restart the phone by holding the lock button. It happens 3-4 times a day, and it´s really annoying. Sometimes when I lock the screen, it wont wake up back again, and I have to pull the battery to restart it. Haven´t installed any new apps on the week before the issues started. What can it be? Is my phone dying?
