Can't Make Moblie Games

I cant make any of my games work on mobile unless I strip them down to bare bones. I understood at first, with my endless runner game, that I was using HQ textures, but then I went and bought SimplePoly City in Environments - UE Marketplace a low poly pack. Using nothing but this pack and First-person Template with no starter content, I still cant get a game to load on my phone, works fine in window play.

How bad I had to remove textures to final get it to load: https://youtu.be/iwqMLAD53VE

You would think I should b able to run the demo map from the simple city pack on mobile without any issues.

I’m I doing anything wrong? I’ve followed UEs apk reducing, but I don’t understand there texture guide lines.

I only like the coding aspect of making unreal games, I’m not an artist. My phones are API 22, 5.1.1

I don’t even care about file size I just want it to run on my phone, that was my goal.

Hello!

Did you see any error when you package your game for mobile? And which texture compression for mobile do you use?

Cheers!
