I've bought a Sony Xperia m4 a while ago and it had a problem where the screen is very dim. I can only barely see it if I shine multiple flashlights on it. I tried hard resetting it and it still didn't work. Is there a way for me to fix this?
Also, I hear sounds from the phone. It makes sounds when I put the volume up and the light shows up when i'm charging. The only problem is the screen being very dim.
