Why does it say on the Google Play Store that my device is incompatible with the app?

Sadly, sometimes the Google Play Store regards certain devices to be incompatible; this can be for one or multiple reasons including graphical limitations - based on an incompatible chipset, country restrictions or carrier restrictions.

Google suggests clearing Google Play Store's data from your phone as sometimes this can cause the app to become downloadable. To do this, go to Settings > Application Manager > All > Google Play Store > Clear data.

If the above method does not work however, sadly there is no other workaround and the app cannot be downloaded.
