    Wow... That's interesting. The resolution is 720p because I initially hard-coded that value.
    I released an update where it matches the screen resolution, I'm curious to see what impact that'll have on a device like yours.

      Resolution:
      1404×1872
      All graphics options:

      • Disabled – [Portrait] 32-33; [Landscape] 38-39 FPS
      • Enabled – [Portrait] 8-9; [Landscape] 11-12 FPS

      But strange behavior of the new version when changing orientation. With the first one everything is fine.

      Let me try to explain. I use a translator and there may be some difficulties.

      In landscape mode all versions are displayed normally. When switching to portrait mode , the left side of the new version with settings is slightly reduced, and the right side (with a dancing man) — stretches to the full height of the window going beyond the right edge.

      But this device is not designed for games at all. You can only play games where the transition from FPS to SPF is not critical.

      And for some reason, Google keeps wanting to check this app. And I have to explain every time that I don't trust Google myself. The option to install without verification is hidden — I could hardly find it.

        Tomcat Thanks for your insight. Even though your device is not designed for games, I'm glad to see that it ran to some extent.
        As for the Google wanting to check the app, I don't know about that, probably because it's a debug build.
