you have to have the app installed and give atleast one star bro.
heres a wee tip before installing an app.. at the bottom of the 3 reviews it says "more" or "read more" or somethin, tap that then at top right theres option to view reviews from your device only.
also before updating an app, select "for this version only" incase its a crap review
also in settings set a pin for purchases incase phone gets stolen.
lol someone should write a play store guide.
n dont be embarressed mate
