My Android App Glitches Out on Some Phones

This is the app in question:

I haven't got any crash logs to share because it doesn't crash. I did get a couple friends to show me what it was doing on their phones, though. The audio seems to work, but graphics just bug out and nothing is interactible. Images tiled across the whole screen and whatnot.

I may try updating my Unity version and making a new build but I would love to know any insight into this.
