Thanks guys.

I'll try these apps, but I don't want to edit system settings again through the Adb console. I think I have some USB boot drivers for my phone and also Adb console, but I don't want to do it. I am lazy. I'll leave it as it is.

It seems to me that in old Android 4.4, old iGO Primo also worked on fullscreen, without a button bar. Oh ... the newer the worse.


Thanks again.
