Ah, so I AM holding it wrong. I didn't realize that and was wondering why it seemed like the screen wasn't always registering a touch. It wasn't a problem on my Note7 so I neglected to adjust for the differences in the S7Edge mI had problems utilising my S7e in day to day scenarios. Typing was troublesome, accidental touches or inadvertent touches where part of your had presses on the edge causing unresponsivness was another and finally just holding the device in landscape watching a movie or such was a hand gymnastic pain.
I switched from S7e to S7 and whilst the e is aesthetically better, the standard 7 is more pleasurable to actually use as I don't have any of the issues in usability that I did with the edge.
I have the Samsung flip cover case (the one with a clear window) and I find folio type cases usually help me hold my phones without touching the screen. But I do sometimes hold the Edge display wrong. I didn't realize that would cause unresponsiveness. Now I know. Thanks!
In other news...Google support is dreadful. I asked them one simple question and in four business days all I got was a useless canned answer of a page full of links to my order that tells me not a thing about the question I asked.
