Did you upgrade to lolipop or did it come pre installed with lolipop as your meant to go to 5.01 or 5.1 direct not 5.0.2 from kitkat...
5.0.2 is a broken build of android... was only released for devices that had broken chipsets that needed fixing...
5.0.2 has lots faults. 1 being some skins released could not turn mircast off...
Mircast is not supported on sky go....
If you select all the options to disable mircast and then delete the app, reboot the phone, insuring all the mircast functions stay off. then reinstall the app... it should now run fine but you can not go near any device that support mircast or mircast will restart on the remote signal boot on your slate...
Mircast issues is one reason im not upgrading from Kitkat... that HP devices normaly have...
