Testing an Android app

Hello there! So I finally got the Android SDK files working on Unreal but the problem is, when I try to package it to a Multi-Android compatiability for testing the game, and send the apk to the device, I get an issue on a key from the Google Play Store, but the problem is, I don’t want to put the game in the Google Play Store, I want to be able to play it while testing it on my phone (without a USB because I dont have one for this device). Is there anyway I can fix that? I know theres PROBABLY some topics close to this but idk if this is a different situation. I just wanted to test on my phone without keeping it wired even if it takes longer lol.

Wat engine version?
4.25 just changed fully the android package method

up to 4.24:
Package in ETC1.
In project settings/Android SDK and android services are Green?
SDK License accepted?
SDKConfig directory are good?

Thanks for the response! I am using 4.25
