And the 2 threads I started soliciting feedback from those who don't have any issues has gotten minimal (though some) participation in comparison. It really makes me hesitate to go ahead with my plan to buy one for me and one for my mother (waiting on Newegg/Negri to get fresh yellow and white stock). Granted, people typically go to forums of this sort to complain, but I've been around these things long enough to recognize when there are more problems than usual for a device, and the 1520 seems to fall into that category, unfortunately.
Can you name a phone that doesn't have any problems? You show me a person that says that their phone (any make) has no problems at all and I will show you a liar. All phones have problems of some sort and also what one person finds a problem another would see as a trait.
Also do you think that all posts from people complaining about problems with the phone(again any phone make) are for real or even have the phone. If you do then you are quite na?ve.
My own option about the 1520 is that it is a great phone, yes it does have some small touch/swipe problems but it is a lot less that the problems with taps that were not recognised with the ios(iphone 3GS, 4 and 4S) and my android phones (Note 1, 2 and 3, S4, Xperia Z and Z1) I could go on for hours listing all the problems I had with those phones.
I do love the phone but I also love my 925 but if I had to pick on it would be the 1520
The size
The form
The screen
The battery
The speed
The smoothness
The wireless charging
8.1 made it even better and cyan will make it better still.
If you look hard enough you will find problems with anything, some people however tent to look too hard for problems for one reason or another.
