"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 :)"

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

I think its work unless there is a hardware problem"

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.
