I was about to install (free) Mahjong by Magma Mobile. But I looked at the permissions. It needs access to the "Phone features..."
We've all seen Mahjong games, probably loads of them. I can't think of any legitimate reason for this game to require permissions to "...determine the phone numbers and serial numbers of this phone, whether a call is active, the number the call is connected to and the like."
Which of you would allow an app to bug your phone? Because as far as I can see, that's what this is asking for. And there are plenty more out there. Google shouldn't even be letting this stuff on the Play Store. But apparently this is a "Top Developer"!
