Perform a Master Reset. Note: Resetting the handset to factory defaults will erase anything stored on the device itself. Back up as desired to prevent the unwanted loss of content. If the signal issue persists after the master reset, there may be a hardware fault.

Open the Wi-Fi settings and erase the network name. Restart the phone and add it again. Make sure the modem’s capacity to host the devices have not been exceeded. Do check if the problem is related with the phone Wi-Fi antenna. Phone model: Huawei P20 Pro. Phone bluetooth was paired with another earbud and sport band. Total 3 bluetooth devices including this L3P. Just got my Liberty 3 Pro few days ago and update the firmware to latest version on Nov 4th release. I was using the phone and and L3P to attend concall using microsoft team. Within an hour time during the concall, the right earbuds malfunction Huawei P20 Pro aren’t always ideal, which is terrible. A system upgrade or software update can sometimes create bugs and difficulties that cause your phone to stop working properly. APN settings that aren’t working are a regular problem. I got myself a Huawei P20 Pro and am fairly satisfied with it atm. But there is one issue I have now and that is that apps like Line, Teamspeak 3 and even the phone app is using the wrong microphone when using a Bluetooth headset or even an USB C -> 3,5 mm headset.
Purchased a Huawei P20 abroad which shows as 'No Signal' when I returned to the UK using my Vodafone Sim; also happens with other Sims too (tried EE and Virgin). The phone is unlocked so I'm not sure why it's not working. Any help is hugely appreciated. Very frustrating issue.
