"1) Connect your phone to a computer using USB

2) Hold upper volume key for 5 seconds as soon as your phone is plugged in to a computer using USB cable.

3) A menu will appear. Use upper volume key and go to the 3rd option which is "" boot normal""

4) Press lower volume key for selecting that option.

Your phone will be switched on automatically."

Restart it just by adding the restart button in the notification panel when you slide down you'll see a 4 dot at the right side.

Change Sleep option to ‘Never’ under settings, display option. Although this isnt a solution, may temporarily address the problem, at the cost of draining batter
