The Stryd app on your phone allows you to soft reset your Stryd. This can be helpful if your watch looses connectivity to Stryd. Stryd automatically gets a soft reset when reactivated when you start a run.
Soft reset does not always resolve all possible software problems. There is a way to do a more compete restart of your Stryd. If the battery is completely drained, Stryd will completely switch off and do a full restart. You can let the battery drain by itself, or you can expedite this process by simulating a run with your phone if it can still connect (connect your phone to your charger, start recording a run and wait).
The battery of Stryd can last up to 20 hours. The LED will start blinking when the battery is low. You need to wait until the blinking of the LED stops, indicating there is no charge left.
After the LED stops blinking, put Stryd back on the charger. It will restart and do a full reset. If you still have problems after the hard reset, contact email@example.com.
