I have recently purchased a second hand Samsung Galaxy Tab A Lite 7" tablet for my phantom 4 drone. The tablet is running on android version 4.2.2 and I can not get the DJI GO 4 app from the playstore. It says that the device is not compatible with this app. How do i install the DJI GO 4 app onto my tablet?

JordyCornes:

There may be a way of jailbreaking the tablet and sideloading the app, but your experience, if you are successful, will not be a good one. That tablet is likely underpowered and thus will be enable to handle the computational demands of DJI GO 4.

If you don't go the 'i' way, then the most suggested Android device is the nVidia Shield K1 tablet. I do not know of the best i choice--others may be of more assistance in that regard. There are more than a few Samsung (and other Android) devices that will work--check the list of approved devices elsewhere on this site.
