Samsung S3 I9300 - screen freezing several times I'm a Samsung S3 user.
After I updated the OS to 4.1.2 (official release), my screen keeps on freezing. I'm fed up with those freezing situations. Any solutions for that?
Thank you.
For those of you who have  updated to 4.1.2 official release, it seems fairly likely that the release is causing the problems. If it is unreliable, you can always try rooting the phone if not already and installing a custom rom which is running on 4.1.2 rather than the official release which is clearly loaded with bugs. Alternatively, you can always flash back to your previous version .  

Someone reported that disabling Samsung bloatwares cleared that issue, and also disabling wifi will decrease freezing frequency.

Look here,all are reporting same problem.
