After the last update on Forerunner 165, my last two activities (running, next walking) always spill the display (the screen appears garbled with distorted text and numbers). The activity is still sensed, the watch beeps, etc. It even saves properly at the end. The display is, for example, spilt for 10 minutes, then it displays completely correctly for a while, and so it keeps alternating the whole activity.
How can I fix this? Has anyone encountered this?
