LAG Issue

Hi,

I've been playing Iruna Online for a while without any problems. But unfortunately on Mar 10, 2014 when I open the app, I noticed that it seems slow. And after I log-in to my account, the problem got worst! I cant even slide the chat menu to the left side and the screen keeps skipping frame-by-frame.

So, I've done the following:
1st: - Clear Data on Iruna Online Apps
       - Closing unused running apps in application manager
       - Restart my device

2nd: - Reinstall the game
       - Update

3rd: - Do Reset Factory Settings
      - Install the game
      - update

Results:
1st: Resolve the problem but the problem occurs a few days of playing
2nd: Didn't solve the issue
3rd: Same with 2nd!

NOTE:
- Good Wi-Fi connection
- Battery status: 90% - 100% during playing
- Device: Samsung Galaxy Tab 3.0 (Unrooted)

So, this is my experience with the game. Any suggestion to resolve this problem/s?
Any help is very much appreciated.

Thanks.
