I bought the "Note Edge" and gave my 1520 to my son back in December, because I missed some apps not available on Windows phone. Well after some time with a high end Android phone (not my first), I had to trade my son back.. Though the edge has 3 gig of ram, there's no comparison to the 1520! Though we don't have access to some apps, it just isn't worth putting up with the lag of running Android. Also, I have the Samsung Gear S watch (gift from kids) & still decided to switch back, knowing I'll have to use the watch as a standalone, being it isn't compatible. So, for anyone thinking of switching to Android, if your looking performance, my experience is, windows flagship is the hands down winner over the Android flagship.
