Sometimes when I unlock my phone with the home button it just turn on the software keys both sides of the button, but the screen remains off. The phone doesn't seems to respond, by any method. It just stays off until it automatically locks again.
Next time, same process, I use the home button to unlock and it works like nothing happens before.
Has anyone face this issue? Is really anoying. My phone is unrooted and with stock firmware. I just try to restart the phone to its factory state but after a while the issue came back. It's not all the times I unlock the phone, but even it is "sometime" it's frustrating.
Any help with be appreciated.
