I've only noticed this morning, the bottom left of my screen looks as if some of it is blacked out, it's like the screen is dead there, does anyone else have this?
Will take pics later but I got a feeling it's a screen defect
See my posts earlier in the thread, I had the exact same issue. Samsung allowed me to purchase a new S7 Edge and then send back the original one for a refund as I wanted to transfer my data over while I had both phones.
Edit: I purchased with the original pre-order via the Samsung website, they might only offer a repair if you purchased from elsewhere and depending on how long it has been.
I had the same problem with the S7E I got on Saturday from CPW. The mark was at the top of the screen, semi-circle shaped. Thankfully they did a swap in store for me.
but once you notice it you can't seem to help not get annoyed by it.
You get the Edge because it is rude not to! There is probably not much point in it but it does give a bigger screen and Edge apps which I do end up using at least once a day. The Edge feels very nice in the hand and looks lovely.
The edge because it looks stunning, you want a larger screen and you want a larger battery.
Or the flat because you don't want such a big phone, would find a curved screen irritating, and you'd rather save a few pounds.
If you've not already, get to a shop and have a look/feel of both.
Edit - as you mentioned VR, apparently it should be slightly better on the flat due to slightly higher pixel density, but I can't imagine anyone could notice the difference...
