Question [Q] Back Camera Issue

Hello everyone

Some few months ago , when Google Camera appeared for the first time , I automatically updated my stock camera app , and since then I'm unable to connect to backside camera>(front one works fine) at the time i thought it was Kernel issue since at that time I was running Franco kernel.I also thought it may be dirty flashing android 4.4.3 , so yesterday for the first time in my country I received OTA 4.4.4 i installed it from my android , but decided to do clean flash today. Same result , what do You guys think , maybe I should take it in for warranty , is it a hardware issue?
or should i rip it open my self and try to fix it?
