The app is Azahar, 3DS emulator, and the gadget is the Ayaneo Pocket DS, operating android 13. Just lately needed to reset it and arrange every thing once more, however this time whereas establishing Azahar it received't go full display. The standing bar nonetheless exhibits on the high.

Perhaps I will help prevent guys a while; one of the fashionable solutions I get once I google is discovering a "Full Display screen Apps" choices within the settings and setting Azahar to full display. These android units should not have that possibility in settings.
