The reason the port uses GZDoom instead of regular ZDoom is because the latter uses code from the BUILD engine for it's renderer, and BUILD uses a custom license that doesn't allow selling anything based on it, even if you make it open-source (GPL allows this), so he removed all the software renderer related code from GZDoom to avoid any legal troubles that could happen from selling it.The port is okay but using GZDoom was a huge mistake in my opinion. He should've used zDoom instead since it offers a similar level of mod support but it's vastly more optimized for lower end machines because it lacks an OpenGL renderer. Because I can only use Prboom I can't use my favorite Doom mod, SmoothDoom as a result.
The resolution thing on PrBoom can be a pain, but you should see the PrBoom folder via USB cable, at least i can see it:If you change the resolution in Prboom even by accident it perminantly renders the screen tiled and therefore unplayable. And this is only fixable by deleting the PrDoom folder in your folder where you put your wad. (Which is only visible in the file explorer on the phone. Not via a USB cable.)

Try setting the resolution manually to your phone's native resolution by using the "-width" and "-height" settings on the parameter line before launching the game, or by editing the config file under Windows or a proper file manager on Android (the default one is just too limited for what i usually need to do on my phone).
