I’ve faced the same issue after a reset of Soundcore Life Q20, so you’re not alone
Some have said on the community to put the device to charge and reset. But I’ve resetted my device without charging and they’ve asked for the password while connecting to Bluetooth and i can’t even turn on or off the device after that.
What I’ve done is just put the device on charge and the issue was fixed.
I guess, you can just put the device on charge and reset it again if you’ve face the same issue again.
I’ve another issue like, the music plays on my mobile device even if it’s connected with the headphone. I don’t know whether the issue is with my mobile or the headphone. Someone please reply if you’ve faced the same issue
