Before updating, ensure that your watch battery level is above 50%.
The length of time required for an update can vary depending on the network performance. Ensure that you have a stable 3G/4G or Wi-Fi connection.
Over the air (OTA) updates require your phone to have a stable connection with your watch. The length of time required to finish the update depends on how long it takes to download the new version and Bluetooth transfer rate.
After the update package is transferred through the Da Fit app, the wearable device needs to decompress and install the package. The update screen (with an upward arrow ) will be displayed on the wearable device. Wait for the device to restart after the installation has been completed successfully.
