Android devices with low resolution scale UI poorly

Whoa, seems the DPI scale the device tells us about is entirely inappropriate for that screen. Very odd.

using MOBILE_DEVICE=OFF should solve this issue (at least it did for me).

If you're able to navigate to Settings/Tools/System Information and check "Name", and tell me what's there, we can autodetect this device and halve the DPI or something.

Due to Odroid Go Advance's resolution, the resolution is 480x320 which is fit to PSP's resolution but the DPI of the menu doesn't fit for that resolution

Without knowing the Name from System Information, I can't detect and modify the DPI for this. I guess could use the tiny, tiny resolution as a hint maybe, but I don't know if that's safe enough.

For other platforms, we have code to detect small resolution/window sizes and reduce the DPI - see UpdateScreenScale(). Android doesn't call this.

@hrydgard PPSSPP detected my Pocophone F1 resolution as 1572x756 for some reason. Is there any way to manually set the PPSSPP resolution?

Or where can I change this value on the phone? I looked into build.prop but found no such value

I noticed that we now have a problem where if you change the display scaler resolution in-game, we don't update the size of our framebuffers, causing some problems.

Yeah. The other day I noticed changing render resolution seems to did the trick in the meantime

Let's merge this issue into #14527 which is the same problem but opposite.
