Alright. My brother bought a used Xperia Z about 2 weeks ago. After using it some days, suddenly this happened. The red LED always stays on while the screen is on. And this is a rare problem. I don't see any problems like this before in XDA. The phone is not rooted nor the bootloader has been unlocked. Can someone help fix this problem, or tell me what partition is damaged, etc? I can't confirm this is a HW damage coz it's not dropped, or punched, etc The red LED acts normally if the screen is off (e.g. while charging, notification, etc).

Factory reset will solve your issue most probably
