Using the Autolock-Feature (on Watchmode, only) will sometimes make the touchscreen unusable.
The VA locks. Then I go outside for a run.
Pushing the button, until the unlock symbol appears. Pushing it again to show apps. Try to select the "Running"-App and nothing happens.
Trying to swipe or something does not work, either. Then the lock symbol will appear again, because I didn´t touch it within several seconds.
Now it cannot be used anymore until you restart it by hitting the button for 10 or 15 seconds.
This happens every 5-6 runs and is quite annoying. I still have not figured out if it is related to any special usage, like charging immediately before a run. Or receiving a notification before or something.
