The Daily Care app includes a feature called "speed guidance", which can be used with the Bluetooth-connected Philips OneBlade. Note: Operating instructions may differ depending on which mobile device you use. Refer to the user manual for your mobile device for detailed instructions. To resolve this, try resetting the connection between your OneBlade and the app by following these steps:

However, if the OneBlade's battery level is below 60%, the update will not take place, and this may not always be obvious to the user. If the battery level is below 60%, the consumer should close the app, charge their OneBlade to above 60%, and then repeat the process of opening the app and tapping the speed guidance widget.

Unpair your mobile device: open the Bluetooth settings on your mobile device, and select your OneBlade from the list of paired devices. Tap “Unpair” or “Forget” to remove your OneBlade from the list of paired devices.If your mobile device’s operating system has been updated since you last paired your OneBlade, this may be the cause of the issue.

Unpair your OneBlade: hold the power button on your OneBlade for 10 seconds to reset the connection. The light ring will start to flash blue.
