I have been using a Pixel tablet with GrapheneOS and a USI 2.0 stylus to take handwritten notes. It all worked fine until I think about two months ago when the stylus didn't connect to my tablet anymore. I now tried it with another stylus (Lenovo Yoga Pen) which worked on my tablet before and still works well on other devices. This pen won't connect to my tablet either, so the stylus itself doesn't seem to be the issue.
Has anyone else experienced problems with USI 2.0 devices on the tablet lately? Any advice on how to fix this?
