Your Android phone could be leaking your Wi-Fi history

[I]f you’re worried about the leak, it’s easy to fix. Just go to “Advanced Wi-Fi” settings and disable the “Keep Wi-Fi on during sleep” option to stop PNO from checking for networks in sleep mode. (In exchange, you’ll see a slight uptick in data and power usage.) EFF has asked Google to address the data leak at an OS level, but it doesn’t seem likely. […] Devices running iOS 6, 7, or 8 are not affected by the bug, although [Electronic Frontier Foundation] reported some data leakage in iOS 5 devices. Laptops running OS X or Windows 7 are also potentially affected[.] – Russell Brandom, The Verge
