How to Fix Brightness adjustment failure on Samsung and other android smartphones?

13

A lot of Samsung devices and other android smartphones show brightness adjustment failure after a certain time of use.The brightness just could not be simply decreased.The smartphone runs only on full brightness.There is no any other way to fix this problem that we have found whatsoever until making this video.We actually are yet trying to find out the cause of this problem.

We after a long try found out an app called “Nightmode”.
With this app we can adjust the brightness ..that is, we can decrease and then increase the brightness of our smartphone.Actually, we tried it on a samsung galaxy s3 that had brightness adjustment failure problem and we were able to fix this problem.
We hope it works on any other android smarthones.if you are having this problem then do give this app a try.
