I haven't had an android for some years now, do they update automatically, or can you hold it off for a bit?
They actually complain that they have an update available. Android and IOS are in competition to complain the most about updates available so they don't look bad in the press, aka fragmentation...
I always keep my devices up to date, usually before actual releases, the reason I've had 5.0 since July.
We have a funny household, my fiance NEVER updates her iphone/ipad's, letting apps go months. I wake up in the morning, check mail, and check the app store on all my devices (g3, n7, n10 and 2 google tv's).
