I have Galaxy Note 3 N900. I update it from OTA (Official Update about 380 MB downloaded automatically)
and updated to kitkat 4.4.2 successfully!
I had low ram problem and getting slow after a while, (I also had this problem before update)
so I root it. then it's buutery usage and ram usage became very good!
But I noticed a serious problem!
somtimes I open default camera app, first it takes photo but nothing saved to gallery, then I close and open it again... but this time camera screen shows black and freezes until I restart my phone!
I found someone else put a video same as my problem on Youtube: youtube. com /watch?v=vQe6IAajras
what's wrong with my phone? Is it because of OTA update or rooting my phone???
Plz help me fix this! Tnx for ur Help!
