Thanks to your answer.
I don't have any problem. This GMXT running very well now.
But, when I used this phone on Anna OS, sometimes I had keyboard problems and sometimes GMXT stop running.
Then, to prevent the same problems like that, I use third party application: memory up pro.
That app will kill every unnecessary processes. So, GMXT will runs better.
or, you can change your cache memory to external, not in drive C.
Anyway, belle is faster than anna, but there's some problems when playing video files.
