fr – App not installed from a valid source

If you are getting the following error:

The app has been installed from an invalid source: Please, uninstall it and install it again from a valid app store.
(Google Play Store or Huawei AppGallery)

To avoid piracy, the app must be installed from valid app stores, like Google Play Store or like Huawei App Gallery. Other sources are not allowed. Therefore, if you haven’t installed it from one of those, then, you need to follow these steps:

  • First (optional) do a Backup of you current Sound Profile settings. This way you will not have to recreate your profiles (see more info below).
  • Uninstall the app.
  • Install it using Google Play Store using this link. Or, if you have a Huawei without Google Services, use the alternative store in your case which is Huawei App Gallery using this link.
  • Restore your previously backup (see more info below).

If you have installed Sound Profile using a third party backup app (many Samsung devices has this option) then you also need to uninstall it and install it from Google Play Store.

To do a Backup of your settings follow these steps:

  • Open Sound Profile and tap on the menu 
  • Tap on More options
  • Tap on Create backup.
  • If you don’t have the necessary permissions then you will be asked to grant them. Once you grant them, tap on « Create backup » again to finally do it.

To Restore your settings once the app is finally installed:

  • Open Sound Profile and tap on the menu 
  • Tap on More options
  • Tap on Restore backup.
  • If you don’t have the necessary permissions then you will be asked to grant them. Once you grant them, tap on « Restore backup » again to finally do it.
