I Cannot use a headset on my phone cause the phone told me headset not supported.
Can you explain a bit more please.
Connected with a plug or on Bluetooth.
Did it succeed beforehand or is this a first attempt.
Which headset are you using?
And last.
Restart the device in Safe Mode
push power button-> press and hold restart-> you will have an option to reboot in safe mode
Test
In safe mode only the original preinstalled apps will run, so any interference from self installed apps will be gone.
