Since my 955 has been updated to FW 12.27 I started to notice that after some time (usually around 2 weeks), touch becomes unresponsive. When it happens, it is not possible to select any widget glance by tapping on it and also scrolling becomes more laggy.
Button-based navigation within the UI remains working even after touch-based is broken.
Restart of the watch fixes the issue for next few days.
Before 12.27 I haven't experienced this issue.
Has anyone else noticed this?
