Handsfree not working A52s

[Maxwurx]

My bluetooth is working when playing music, videos etc on all devices but not working when handsfree required for phone calls, earbuds or car etc. Any ideas?

I had the same problem which was fixed by a cold reboot of the phone and allow the phone to optimise apps.

How did you do this and did it resolve it permanently
