Unable to connect Fairphone earplugs after call has started

[Vanessaberg]

I am unable to connect Fairphone earplugs after a (WhatsApp) call has started. I am unable to enable Bluetooth, the screen gets black and normal again and again, and I actually can’t do anything, not even open the screenlock. This just happens after I have answered a call, meaning that I always have to call back, but first enable Bluetooth, connect the earplugs…

Hi and welcome to the forum.

Which phone are you using?

Do you try to pull down the menu to enable BT?

Black screen when pulling notification tray during call

Hello. Is it possible that you cover the proximity sensor when you are swiping down? It’s on the right side of the selfie camera, directly above the screen. Try swiping more on the right side (closer to the battery icon) or on the left side of the screen.

Oh, thanks, that sounds likely, I will tr that! Thanks again!

Ok, tried for a tjme, but thst did not help. It seems to be that a WhatsApp call blocks everything, no matter what I want to dk, I am not able to “reopen” the phone, cause the screen locks, even if I was working with my phone, hence no screen lock. So the problem seems to be the following :

1. When a WhatsApp call appears, the screen got locked, no matter what
2. I am not able to unlock the screen lock (neither by code nor fingertip)
3. If I touch the reopen sensor in the middle right side, The screen is flashing black - screenlock - black - screenlock.
4. So it is not only impossible to connect earbugs, everything is impossible.
   (and yes, I hate WhatsApp due to Meta/privacy policy, but unfortunately some important friends insist )
