I would have believed this until I used a 3rd party app to check control brightness, that worked perfectly fine. I would try a phone reset but right now using the app.

Hi Nitish,

Are you sure auto-brightness is not activated?

Perhaps energy saving is enabled?

To test everything with your screen i suggest you launch the test menu and see if everything works there, there is a special button called "dimming" there to test as such;

-> go to your "keypad" (as if you want to call somebody)

-> Type in: *#0*#

It should start the test menu instantly.

Let us know what the tests do :)

If you have replaced your display folder then sometimes you face this problem , because of cheap quality display folder .

For this you have to download night mode application from play store .It will work for you.

Reset your device and off the auto power saving and try again

If you have changed your phone display then it might create problem because some china display doesn't have the hardware that support display brightness. If not so then try factory data reset this might work.

First check the auto brightness option,This is the symbol of copy Lcd only to display the graphic not controlled light system and phone also goes to heating up problem better to change original OLED LCD.
