Nexus 5 Camera - Accelerometer problems

Hi :) as always, I was trying ROMs for best daily usage. But one day, after installing NexSense (Sense 6 porting), something happened and after that and restoring CM backups (CM Caf version) I saw that accelerometer is no longer working with any rom (tried 4.4.4 + 5.1.1) and (something more strange) camera modes: Panorama and Photosphere are no longer working (o.o how could be?).
I attached screenshots about this problem.
Anyone has info about these problems?
Thank you in advance :)

LG G2 accelerometer sensor slightly faulty

Since 1 month ago this phone worked really well. But a month ago the accelerometer stopped working, and since then it's on and off...I want to take it to warranty, because I tried three different kdz and the problem still persist so I'm quite sure it's a hardware error.
My question is because the accelerometer works for 1-2 days if you restart the phone, will the guys from warranty have problems in diagnosting the error? I don't want to sent it to warranty just to stay without the phone for 2 weeks and to get it back same way...Here is how the CPU-Z show the problem!
