I bought a 1st gen Pixel in December 2016, so it's just over a year old. I'm delighted with every part of the hardware, except the screen. After around 6 months I noticed that the nav buttons are really badly burned in where the nav buttons are located([1] picture is not mine but it demonstates what I mean, I believe at this point mine is much worse than in this picture).

This is due to the nav buttons being constantly visible in most apps, an option to hide them and only spring up when required would be perfect. It's not the end of the world but it's one of those things that once you notice it you can't forget it.
