I had to hunt down my first Note Edge in October 2014. It bricked on me in April of 2015, which was replaced and that one started freezing up on me and randomly restarting every hour about 3 weeks ago. I just replaced it Monday. And I still will keep the Note Edge because it is a great phone, I can remove the battery and I have a 128gb microSD in it.
Yeah, I had that same issue with the phone restarting randomly. They asked would I like to upgrade to the note 5 and I said: hellz no. They guy on the phone who did the replacement said "I knows what you mean" when I explained why the edge was better that the 5 and the recent galaxy offering. There is no phone that touches the note edge in design, functionality and usefulness IMO. I wish they would not have just used it as test for the market and nade it a flagship every year.
