Once you have paired your HUAWEI phone to a Bluetooth device (accessories, wearables), they should automatically reconnect if Bluetooth is enabled. If this is not happening, please follow the troubleshooting steps below.
If the headset or the speaker is too far away from the HUAWEI
smartphone it was paired with, it will disconnect and exit the
pairing mode and it won't automatically reconnect to your phone.
To solve this, open the Settings on your HUAWEI
smartphone, search for the Build number and tap on
it several times until the message 'You are now a developer!' is
displayed; if prompted, enter the lock screen password.
Return to Settings, search for
Bluetooth auto-connect and enable this feature.
Make sure that the other device is within the effective Bluetooth
range from your smartphone and restart it.
Re-enable Bluetooth on the phone and check if the issue is
fixed*. If the Bluetooth device still fails to reconnect, unpair it
from your phone and then pair it again.
*If you are using Sony WI-C300 Wireless In-Ear Headphones, you need to touch the name of the headphones on the Bluetooth settings screen to manually reconnect them to your phone.
If an error message is displayed when your car tries to reconnect to
your HUAWEI phone or the connection fails, it is possible that the
Bluetooth car kit does not support automatic reconnection.
In this case, open the Settings on your HUAWEI
smartphone, search the for Build number and tap on
it several times until the message 'You are now a developer!' is
displayed; if prompted, enter the lock screen password.
Return to the Settings, search for
Bluetooth auto-connect and enable it.
Then swipe down from the status bar to open the notification panel
and touch and hold the Bluetooth icon to enter the Bluetooth
settings screen.
Make sure the name of the car kit is in the list of Paired devices
and tap on it to reconnect.
On the Bluetooth car kit, search for the Bluetooth name of your
smartphone and touch it to reconnect the two devices.
If the issue is not solved, delete the car kit from the Paired
devices list on your phone and try pairing the two devices again.
