14 DAY TRIAL // It's been less than a day since Samsung announced the cause of the Galaxy Note 7 explosions, which, ultimately, led to the phablet's demise. The South Korean company kicked off a couple of exchange programs that would allow Galaxy Note 7 owners to switch to another Samsung smartphone (usually, the Galaxy S7 edge) and receive the money difference back.
So, aside from the original customers, Samsung also turned many Galaxy Note 7 owners into Galaxy S7 edge users. Unfortunately, the Galaxy S7 edge is not a phone without faults, it's just that some of the issues affecting the handset haven't made headlines yet.
As pointed out by Myce, the Galaxy S7 edge is plagued by a dangerous display problem that can't be fixed. Many owners have been complaining since last year about a vertical pink line that shows up on their display.
The large majority of these users haven't dropped their phones or scratched them so it's most likely a hardware issue that leads to the Galaxy S7 edge display's failure.
There are many threads posted on various carriers' forums, including AT&T and Verizon in the US, O2 in the UK, Vodafone in Germany and the Netherlands, Telstra in Australia, as well as Reddit.
The only way to get rid of the problem is to send it for repairs, but more often than not, these Galaxy S7 edge devices affected by the pink line issue are replaced by Samsung or carriers if the smartphone is under warranty.
One workaround can temporarily fix the issue, but it's not working for everyone. You'll need to reset the display in the service menu by typing *#0#* using the dialpad. From the menu showing up on the screen, tap on Red, Green and Blue colors, which should reset the display's pixels. Try a couple of times if it's not working.
Other users claim they've managed to remove the pink line from the smartphone by slightly pressing on the top of the display, near the Samsung logo and front camera.
However, both of these workarounds will only fix the issue temporarily. In time, if you don't repair a Galaxy S7 edge that's been affected by the pink line issue, the display will turn black, so it's clearly a hardware issue.
Samsung hasn't yet recognized the problem as a widespread issue, so service technicians don't yet know how to handle it. But if your Galaxy S7 edge is under warranty, then you should definitely ask for a replacement.
