5. Troubleshooting (FAQ)
5.1 Watch cannot be found in the APP or time synchronization issues
If you encounter problems such as the watch not being found in the APP, or the watch not synchronizing with your phone's time, consider the following:
- Ensure your phone's Bluetooth and GPS positioning are turned on before initial use.
- For Android users, the APP must be granted positioning permission (check Phone Settings > Applications).
- If the watch was previously paired via your phone's Bluetooth settings, first unpair it, then search for the connection within the "GloryFit" APP.
- If the watch has not been used for a long time, Bluetooth may enter a dormant state. Turn off Bluetooth on both the watch and phone, wait approximately 1 minute, then re-enable them and try searching for the connection in the APP again.
- The watch must be connected to the APP for functions like steps, sleep, and time to work correctly.
5.2 No alert function on the watch
If you are not receiving alerts on your watch:
- For Android users: Follow the on-screen prompts in the APP to set operation permissions, or enable the information reminder function in the APP and grant APP notification permissions as prompted.
- For Apple users: After connecting the watch to the APP, your phone will display a pairing request. Select "Allow Pairing" and enable the application reminder switch within the APP for the apps you wish to receive notifications from. Additionally, go to Phone Settings > Notification and ensure "Notification Center" is enabled for the relevant apps.
5.3 Reminder switch is on, but alerts are sporadic or absent
If the reminder switch is enabled but alerts are inconsistent:
Ensure that information notifications and corresponding notification permissions are active on your phone as per the above tips, Bluetooth remains on, and both the APP and watch maintain a continuous connection. If the system-authorized APP alert function is not working, you may need to re-check the message push function settings within the APP and your phone's system settings.
5.4 Android phone Bluetooth disconnects frequently or no message alerts after some time
Android systems may periodically clear background applications or power-consuming apps to maintain smooth operation. If the "GloryFit" APP is not configured to allow background running, it may be closed by the system, leading to Bluetooth disconnection. Different Android phones have varying methods for APP background running settings. For example, on Huawei nova 8 SE: Go to Settings > Battery > Power Consumption Ranking APP > Application Launch Management > Manually manage to turn on background running.
