Some Troubleshooting steps-Please ensure that you have the latest version of Huawei Health Make sure that your watchband is updated to the latest version. Take around 20 steps and then check if the step count is displayed. The wearable will display the steps after you have walked for a little while. Restore your wearable device to its factory settings. Pair it with your phone again and check if the issue is resolved.
