I have a Neo V that was stock and worked fine till a couple of days ago when I noticed that after I lock it, the screen doesn't turn on again,even though the phone is still on. I installed several stock versions of ICS and GB without much luck. Yesterday I unlocked the bootloader and I flashed a Lupus kernel with moProject rom (JB 4.1). After that the phone seemed to work ok. I left it locked overnight and in the morning same problem occurs again. Any ideas on what to try to solve this?
