Yellow hue on your Nexus 5X screen? No worries, Google will replace your phone
If you are one of the Nexus 5X owners that has a yellow hued screen, you should contact Google customer service immediately. Some of those affected by this problem have been sent a replacement handset. On the other hand, you might want to wait to see if the yellow goes away as it has in other situations. In those cases, it took about a week for the yellow to disappear.
You can check out some photos comparing affected Nexus 5X units with other unaffected handsets, by clicking on the slideshow below.
