Help! I think signature problem

[loAnto]

Hi everyone, I'm a complete novice at this. I managed to modify the behavior of an app. After that, I recompiled the app, zipaligned it, signed it, and installed it on my device. When I try to launch it, it tells me to install it from Google Play. Could someone with expertise help me bypass this issue? The problem is probably in the signature.

you should provide the app name

It could be anything, that's why you should provide more information. It could be pairip, and you would need to disable it by editing the XML file, or a simple check and you would need to remove it by smali
