I recently changed from the iPhone 6 to the Samsung Galaxy S5 & i also picked up a Nexus 5 16GB on the cheap to try out Android 5.0 ie Lollipop, which i downloaded a few days ago and installed myself. I have have a 16GB iPhone 6 of my sisters sat on my desk that I've just upgraded it for her to 8.1.1 because she doesn't like doing updates for some reason, in case she breaks her phone. What i find interesting is that Android 5.0 is more stable on release that what iOS 8 currently is which has been out now for over 2 months and had a few updates since then. Now don't get me wrong there are bugs in Lollipop but I've yet to encounter any on my Nexus 5 WiFi works fine and not getting any battery drain others have been reporting along with with a couple of other quirks that been reported aswell, but for me it been plain sailing. On iOS 8.1.1 the bugs that plagued this OS since launch still haven't been fixed which is annoying to say the least, tbh i glad i returned the iPhone 6 when i did as i couldn't put up with these problems. You've got to wonder what going on at Apple atm, considering they only got a few devices to update you think they have the OS spot on, but all seem to happen is once they fix one problem another problem crops up, and by the time iOS 8 is usable, it be end of it's life and people will have to go though the new problems again with iOS 9 So as it stands now the most stable platform to be on between iOS & Android is Android.
