Many members recommend MX player but Google play store doesn't give me the option of downloading it to my nexus7. It will only let me download to my Samsung galaxy phone......frustrating as it is very good on that and the standard Video Player only plays in portrait mode even though screen rotation is enabled.
Does anyone have any ideas please, while I still have some hair left to pull out? Thanks.

After trying to install another app it appears it's not only MX Player which won't install. NO APPS will install to it  HELP !
