I successfully changed an app to a system app, but it still doesn't show it on the launcher

    ZTEGuy That will not work. You would need to mod the launcher i think

    Anyhow I used Lucky Patcher to remove video from the gallery app

      Jumptoheaven that's where i took it from. I am using a root app and can switch back and forth from a notification.

        Jumptoheaven That resolution makes it impossible to see anything!

        thanks

        I modded the gallery to not have video. I Installed it using lucky patcher to disable signature verification. I can recover from a brick and don't have personal info on my phone. If you are concerned to use lucky patcher, just delete the current gallery From system folder and put this gallery.

        How should I install mod apk?

        I installed it thru adb, but then I had to use lucky patcher to change it to a system app. And after all that the gallery plays video!

        I modified the app with lucky patcher myself, and it works!
