Not full screen on big tablet ( Huawei mediapad T3 )

I have the latest apk manually from your site. The menu is full screen but the gameplay is like this. Any ideas why? The resolution option during gameplay is only 800 x 600 and on the app menu has many selectable but no matter which one it defaults on 800 x 600 anyway after you set it. My tablets resolution is 1280 x 800

Download the VCMI Essentiall Files , and but it in the mod folder
