[ SOLUTION ] ANDROID Backlight turns on and off on its own

Backlight turns on and off on its own

Problem: I encountered this problem on HTC One X, HTC Desire Z and HTC Desire S. I suppose this doesn't concern HTC phones only. This is not the most serious problem in the world but it can be a bit annoying when your phone, out of the blue, turns the screen on in the middle of the night just to turn it off in a few seconds. I guess it can also significantly reduce the battery life.

Solution: In one phone this Android problem disappeared on its own  as suddenly as it appeared.  In HTC Desire S it was enough to restart the phone (hold the power button for a few seconds and then tap  Restart).

However, in my HTC One X  the problem didn't disappear until  I restored factory settings. To do that,  go to Settings > Backup & reset > Reset Phone. Remember about backup.
Android Problems: Let's reset our Android device.

Difference between microprocessor and microcontroller

A microprocessor (abbreviated as μP or uP) is a computer electronic component made from miniaturized transistors and other circuit elements on a single semiconductor integrated circuit (IC) (microchip or just chip). The central processing unit (CPU) is the most well known microprocessor, but many other components in a computer have them, such as the Graphics Processing Unit (GPU) on a video card. In the world of personal computers, the terms microprocessor and CPU are used interchangeably. At the heart of all personal computers and most workstations sits a microprocessor. Microprocessors also control the logic of almost all digital devices, from clock radios to fuel‐injection systems for automobiles.
