Hello everyone, I have a problem that I need help with. I have installed mod apk from forum sites (liketechloky,..) on my android 12 phone. But I don't understand why it doesn't work. I'm not tech savvy so can anyone help me out. Thank You!

You need to tell us the specific app/releaser, some arent compatible/some are. Most apps these days probably are, A13 is a whole new story, i personally dont encounter much problems with my a12 device. If the app isnt available here, you should probably ask where you downloaded the app.
