The Galaxy S7 and S7 edge are great phones, and I like both of them - honestly. Unfortunately, since I received my Verizon S7 edge review unit last week, I've had an annoying and persistent problem with the touchscreen. Namely, it's far too sensitive around the edges of the display.
The problem manifests quite noticeably. If you have an S7 edge, open the camera app and hold the phone with both hands in landscape mode, with your fingers grasping the corners of the display. Can you reliably get the shutter to detect your input every single time you press it? I definitely can't, at least not most times. But my colleague Ryan Whitwam has no issue, and Mark Burstiner, using a Canadian S7 edge that received a patch specifically for the edge display, also can't reproduce it. But some of you are telling me that your phones are similarly afflicted, and I've got reports from both US and European users vouching for the existence of the issue.
What seems to be happening is that the S7 edge's display is not properly rejecting the grip of your palm or fingers at the edge of the display panel, which your fingers and palm are bound to touch simply because of the nature of the curved display. There's no fat mid-section to grab on this phone - it's incredibly narrow. The problem also affects me when I'm using the keyboard pretty regularly (especially in bed, when I'm holding the phone more awkwardly), with the backspace button sometimes not detecting my inputs. It can be incredibly frustrating.
@RDR0b11 Don't worry, I noticed the exact same issue on my T-Mobile variant and it's driving me crazy.

The problem can be reduced, obviously, by adjusting your grip of the phone. But this is unnatural and bothersome, especially when you're grabbing the phone often hundreds of times a day. Some users are likely to be more affected than others simply based on the way they hold the phone (cue "you're holding it wrong" part two - I jest), and I think that's part of why we're not hearing about it in such a widespread context.
@RDR0b11 It's the edge sensitivity issue that caused me to return my edge in 24 hours. I got a very knowing 'nod' from the rep

I've reached out to Samsung about this issue in an attempt to verify the scope and nature of the problem, but I think it's something they're already aware of. When the S7 edge launched, Samsung supposedly released an "urgent" OTA meant to address issues with the edge display. I just received an update on my Verizon model (with no mention of the edge display), but sadly the problem persists. I've verified with a user on T-Mobile that they also received a similar update, and the problem is still occurring for them, as well. It's possible the updates we received did not contain those fixes and that "fix" and US users will have to wait a bit longer. It remains unclear, and I've asked Samsung about that update as well, but have yet to receive more information.
@RDR0b11 what issues? For me it was too sensitive...

My strong assumption is that this is a problem that can be fixed (especially given the edge display patch is proliferating on non-US phones). Until then, especially if you're in the US, I wouldn't necessarily advise against buying an S7 edge, I'd just say it's something you should definitely be aware of until we learn more about the problem and when the update will trickle down to American versions of the device.
