Since the end of December 2017 I own a FR 235. Meanwhile the edges of the display turn yellow/brown. Right side a bit more. I can see it on white backgrounds but even on my watchfaces that have yellowed numbers in these areas. Some watchfaces I can't use or not with blue colors because they look a bit green there, espacially right side. It's really annoying because it's now the second watch that has this problem. My FR 35 got these yellowed areas after a few months too. When I contaced Garmin last year because of the FR 35 they told me that I should contact them if I can't read the display anymore or if something else fails. Before that will happen it wouldn't be a case for repair/replacement.
Has anybody else these problems with the display? Obviously Garmin's displays have a poor quality. But not only the displays... The piece of the strap that holds the end og the strap while wearing it on your wrist gets wider and wider and slides so everythings hangs... Had it extremely on the FR 35 where I used tons of tapes to make the strap thicker, now I get it with the FR 235 too.
