I installed official 4.4.2 on March 15th. Later on 19th it just stopped working. My I9505 is rooted, used it to record videos from screen and deleting some bloatware, i wasn't dealing with no custom crap, just a plain root, but i red that this voids warranty either way. I really don't know what to do, after checking CPU-Z my sensors seem to be fine:
And yes, i checked if Auto-Rotation setting is ticked in notification bar, restarted phone, turned off for several seconds and turned back on. Downloaded an app called Sensor Tester from Soaus which allowed to calibrate accelerometer, that didn't work either. I even smacked with care the back of my phone to get sensors back in their place (if they didn't already) and that didn't work too.
Looking forward to your help, thanks in advance!
