Baseus BH1 Lite Microphone Not Working with Infinix GT 30 Pro

I have been using a Baseus BH1 Lite Bluetooth headset together with my Infinix GT 30 Pro phone, and from the very beginning the microphone has never worked correctly with this combination. Even though I have granted all the necessary permissions, during use the phone’s own microphone continues to pick up the sound instead of the headset microphone. This issue occurs especially while playing PUBG Mobile, and other players hear the sound from my phone’s mic, not from the headset, which makes communication very difficult. I have sent feedback about this problem many times, but so far there has been no solution. I believe this is a software or settings compatibility issue between the headset and the phone, and I would like it to be fixed so that the BH1 Lite microphone is correctly recognized and used as the audio input device in PUBG Mobile and similar applications. I kindly request that you investigate this incompatibility, provide a clear solution or guidance on the correct settings, and if necessary update the software so that I can properly use the Baseus BH1 Lite microphone with my Infinix GT 30 Pro.
