Hello,
A few days ago a pink vertical line appeared on the right side of my display. I've only had this device since October, as I decided to exchange my Note7 for the S7 Edge. Apparently, after doing some research on Google, this seems to be a common defect with this device. One temporary fix is to push lightly near the right side of the Samsung logo on the top of the phone. However, eventually the pink vertical line will reappear. My device is still in great condition and I treat it with care so this is disappointing to say the least. Will I be able to exchange it in store with a new device free of charge? Thanks.
