Glad I got mine massively discounted through work - seems a lot of stories of them suffering problems after awhile - mine has now started to periodically restart itself (looks like sometimes its freezing and some kind of "watchdog" rebooting it). Hopefully makes it to around the middle of 2017 and I'll look at replacing it anyhow or end up fully back on my Note 1 that has suddenly decided its going to behave itself again battery life wise :S
