I had the old Nvidia Shield with Marshmallow 6.01 and Nvidia pushed Nougat 7.0 upgrade to the box. Nougat 7.0 really limits access to settings and Google limits the apps you can load on it. I sold the Shield Tv 16gb version and bought a CSA93Q3, went into settings and disabled Google services and Google Playstore, turned off notices and all permissions. Less background crap running on a box, the fewer problems and faster service. I use an older emulator, ( 9.05 } version and freezing is almost totally non existent. I'm not a fan of Nougat 7.0 , Google Playstore or Nvidia Shield as you may have bought the box but they apply the restrictions on what you can do and what you can't do with it.
