My phone was blinking so I did a force-restart. When it came on it seamed normal but when you lock the screen (manually or timed lock), the screen will be black and will not respond to the unlock screen buttons but the phone will still be on (you can listen to music playing, the phone will ring if a call is coming in and the alarm could ring). The only way to use the phone is to force-start it with the power and volume-down buttons pressed for 15 seconds. Please help.
