I am on a large wireless network (eduroam) with hundreds of devices. For some weird reason I do not understand my phone gives me a notification every time a device disconnects from the network. This gives me an endless stream of notifications in the bottom of my screen, naming the device name and user disconnecting from the network. This is extremely annoying as there are so many WiFi devices on the network.
I didn't even know this was possible on 802.11 networks but somehow my phone does this. I am on cloudystock 1.3.
