Go to settings > motion. See if any of those features are turned on. Maybe it's because ur proximity sensor is being triggered.. Or smthing of that sort.

Only zoom and pause and mute options
And it does that when I put it on disk
Thats mean no motion!!!!!

sorry for the bump but how can this be fixed?
I have a similar problem, where I just locked the phone. Then after 1-3 seconds it lights up again - UNLOCKED - without me ever touching it. It's a little bit scary. On 4.1.2 atm, stock rom.

NFC Help!!!

For some reason my nfc will not stay on, I turn it on and it turns off immediately. .. iv tried a few roms and all are the same way
Is there a fix????

Wifi problem

Hey guys my friend's note 2 running on 4.1.2 suddenly couldn't connect via wifi. Everything is working except the wifi. What could be the cause of this and any suggestions on how to fix this? Thanks.

Touch is messed up

Doesn't anyone have a problem with the touch not responding or just random touches running on any rom 4.4.2. On 4.3 I didn't seem to have the problem, just on kitkat

i noticed this morning. Turns out my screen was dirty. A quick wipe did the trick.
It is very common. Check out this thread. http://forum.xda-developers.com/showthread.php?t=2428133

I was having the same issue back a few days ago, just put the phone into safe mode..if it stops doing that it means its one of the apps installed is the problem. If not just try a factory reset.
