Hi @Muhammed2, I am very sorry to hear that.  

Could you fill me in with some more information regarding this? Does the brightness not adjust when you move the slider, or is there something else?

A good start would be to try to see if the same occurs while in safe mode as @nolramlb wrote above. Should it persist in safe mode, please inform me some more details and I'll do my best to assist you!

Thank you for clarifying. Hmm, did it also persist while in safe mode as we mentioned above? If it still persists, could you try a software repair using Xperia Companion to see if it could be software related?

If this does not help with the behaviour then I am sorry to say that I recommend letting a technician examine it at an authorized service center. In order to have it sent in, I advice that you get in touch with your Local support in order to be assisted as they are well informed regarding local service routines, warranty terms and consumer laws. I would gladly assist you if I could, but as I am based in the Nordics I'm afraid that my service routine knowledge is limited to my own local market here.
