Nokia India — screen glows after phone is locked

I have nokia 2.2 phone. I'm facing a problem with the phone that screen keeps glowing even after phone screen is locked, like it's brightness automatically increase even if it is at minimum level. It consumes more battery and makes phone very hot. As battery dies very soon we are forced to charge very frequently. It might reduce the battery performance and overall performance of phone. Please look into the matter as soon as possible. We will be highly obliged.
