You can "force" the resolution to match your device or to go fullscreen in case would you miss any buttons at the bottom of your screen by adding the following into your SYS.TXT
Code:
[rawdisplay]
screen_xy="800_480:1280x720/720x1280:fullscreen,800x480/480x800:fullscreen"
driver=engine
remove the ":fullscreen" if you want the android top-bar be visible
The SYS.TXT is located at /data/data/com.navngo.javaclient and you must be rooted to access this directory. You can also modify it within the APK, don't forget to sign it (with signapk), otherwise it wont install.
