S4 Constantly Lags/Freezes randomly
My Galaxy S4 phone tends for freeze up/lag a lot in the last month.
It lags when:
-My phone is locked and I hit the power or home button. The screen quickly flashes on and off, and will stay dark until a minute or two later when it finally releases itself and then I can use the phone again.
-When I'm texting. The screen freezes and can't type anything. After a few moments the screen goes black. I hit the power/home button and everything works again.
-I'll be randomly using the phone, and then the phone freezes and like the previous post, have to wait til the freeze/lags releases the phone before I can use it again.
- The freezing/lagging happens randomly. It can happen after 6 hours of usage, or after 5 minutes after powering up my phone.
-Did a factory reset, but that hasn't solved the problem
-Wiped the Cache Partition. Nothing.
Is there a way to isolate the problem and figure out what is causing this?
Is this a good question?
