I have had my Nextbit for almost 5 months and have never had problems until now. In the middle of my phone, 3 dark purple spots appeared on my screen recently. They are in the middle of the screen and only show up on a dark background, but aren't visible on a light background like white. This is not in only in one app, it is visible from any dark colored image like the turning on/off screen that is black and says Nextbit. It looks almost like a discoloration that is made up of 3 small dots on the display. I have not done anything to cause this like dropping my phone or any other form of physical damage. I am unsure if this is covered by the warranty since I didn't drop my phone or mistreat my phone. I will post images if needed. @Khang, would this be covered under the warranty?
