We ain't got a PC...nor a laptop
We just redownload it, just to be safe, but it's still crashes...
Joiplay is an app that you put on your phone - it allows you to play PC games on Android :) sniperbm is advising that your friend installs the app, downloads the PC version of CK and runs it through that.
Apart from that, I'm afraid I don't have many ideas. Unfortunately Ren'py and Android don't always play well together and certain phones - especially the lesser-known (and thus harder to test on) brands - will throw up numerous strange errors. It's something that the creator of Ren'py is constantly working and iterating on, but I'm afraid there's no timetable for specific phone fixes.
Give Joiplay a try, though! It has a very high success rate on otherwise recalcitrant phones. You can find it right here:
