It has only been a week since the OnePlus Nord has gone official and people are already experiencing some issues in terms of the overall product. Some of the early users are experiencing display issues including the purple tint issue as well as off-axis issues with the colors. The reports have started appearing on various fronts, at the moment with early adapter complaining about a variety of issues that they are currently facing.

Reports have been appearing on a number of platforms about these issues, including Reddit as well as official OnePlus forums. Users have been reporting a host of issues they are facing ever since they have received their pre-orders. In case you don't remember, the OnePlus 8 Pro was also suffering from the same issues, so we are not sure that the issue with OnePlus Nord has something to do with hardware or it is an issue that can be fixed through software.
