Enable developer options by going to "About device", then tap on the build number 7 times. Developer options should now be enabled. Then, in the settings, search for "Force allow apps on external", then you should be able to install apps on your SD card. But you may need to format it as internal storage.


**Note: If you format it as internal storage, all data on the SD card will be deleted. If you do this, back up any important data beforehand!** Your internal storage will not be affected by this.

To do this, in the settings, go to "Storage", tap on the name of your SD card, then tap on the menu in the right-hand corner, and hit "Storage settings", then hit format.
