When mass producing any device as complicated as a smartphone, there are bound to be one or two bad units in every batch. Screen discoloration, usually manifested by a yellow tint on a smartphone’s screen, seems to be one of the most common issues, and has plagued the likes of the iPhone 4S, Sony Xperia S, and now the LG Nexus 4.

After an XDA user posted the above image, along with some others, the thread has since grown to over 40 pages. Throughout the thread, there are users reporting the same problems. Most seem to agree that the problem is worse when the device is hot or running a performance intensive application, but a few claim that the defect is always present. In general, users seem to be having no problem getting a replacement from Google, as Google has amended its warranty fine print for the Nexus 4 and should take back devices with manufacturing defects that are up to a year old.

While this is certainly an issue to be aware of, I don’t think it will end up being a problem even as big as the Nexus 7′s screen lift issues. According to accounts from iPhone 4S users with the same problem, the discoloration sometimes goes away when the display’s glue is given time to set. Even the few users whose problems persist should have little trouble getting replacements. Of course, this slight flaw might be due to Google trying to push out Nexus 4 units as fast as possible, and although I would like to get my phone sometime in the near future, I’d prefer it without any yellow tint.
