Can anyone help me?
I try installing button mapper on my LG Classic and it gives me a message saying that app not installed

    Atusb Which button mapper (from where)?

    Put APK in the phone's Download folder and run in WebADB

    pm install -g /sdcard/download/filename.apk

    .

    Replace with real filename. Tell me the output.

      Atusb is it in the download folder? what happens when you press it from file manager?

        Atusb Its in the download folder of your internal storage?
