I've had an x3 with crosspoint for a couple of months. Overall I love the device, it's making it easy to pull up the phone and read a couple of pages instead of doom scrolling. But a huge drawback is that it's unusable in direct sunlight since the screen fades away. Here is how it looks: https://www.reddit.com/r/xteinkereader/comments/1q5fhwf/dire...
I contacted support and they answered
"We would like to clarify that on e ink displays, text may appear lighter under very strong direct sunlight. Once the screen refreshes or you return to normal lighting conditions and turn a few pages, the text will fully recover. This behavior is related to the low power design of the display and does not cause any damage to the screen."
Crosspoint has a software fix for this in settings. It’s not 100% but it does work. It’s called the Sunlight Fading Fix under Display settings. https://github.com/crosspoint-reader/crosspoint-reader/blob/...
Oof... I just ordered the x3 and plan to add CrossPoint on it. If hesitating to cancel my ordered as it didn't ship yet. I have plenty of other e-ink screens and it has never happened. I specifically enjoy e-ink in directly sunlight or at least outdoors ... so I'm not sure if that's still a good usecase for me anymore.
Thanks for for sharing.
Apparently the cable to the screen is to blame and the workaround is a piece of tape to block UV light reaching that component: https://www.reddit.com/r/xteinkereader/comments/1qlyq3s/this...
Personally, I've found that just moving the screen out of the sun (for example by turning it upside-down, or holding my hand in front of it) when refreshing a page is enough to prevent it.
