Bluetooth is broken on ZenFine 7 since Android 10 that came with the phone.

When connecting to bluetooth speakers or bluetooth in car, audio fails to play back intermittently. Disconnecting and reconnecting bluetooth sometimes fixes it. When audio fails to play back, it may play for a second before cutting off even though the playback app is still playing back audio and the seek back is still moving. If i use the toggle to switch between bluetooth audio and phone speaker, the audio is clearly playing and audible through the phone speaker but not the bluetooth.

Phone calls will answer in my car's head unit, but occasionally the answering system locks up and i have to manually swipe to answer on the phone itself.

With my Zenfone 6, these same bluetooth devices worked perfectly.

With my temporary Sony Xperia 5 mk1, all these bluetooth devices also work perfectly.



  • Try going to system settings -> system -> reset options -> reset wifi, mobile & bt

    We have not seen more reports on BT issues than usual with A11. What about your connection to other BT devices? Are the acting the same?

  • I am using bluetooth in my car every day and I have no issues with it. I even changed my stereo in my car and the bluetooth is still fine. Maybe it is something with the car audio sistem?

    The only problem with bluetooth in my car is that if someone calls me on Whatsapp, I see the caller id like 100000000 and not the real name. And this is an Asus issue since I have 3 phones connected to the car and only this asus behaves like this...
