Hi - I know this issue(s) has been repported several times, and for many handset models - and does not seem to get any attention from HMD - But I hope repeated repporting will somehow help :-/ (There are other issues too reported with BT Audio/Connectivity - but I can only repport what is happening with my equipmet combo)
I use different bluetooth audio equipment - and all is behaving differently, but none is working like it should with Nokia phones.
All external equipment has latest Firmware (and several updates, without change) - And the faults has been unchanged for the latest updates of the phone.
I have tested all equipment with several phones (Huawei/Honor/Motorola (X and Z series - Android 7 and 8)/Sony/Samsung) - and all equipment is working OK with all other phones.
I have tested all equipment with one other Nokia phone (Not too many of my friends want to buy a Nokia from HMD - As i've not been the best ambasador) - and it has the same issues. - I've tested every trick I've found online about this issue (mostly stuff in Developer options) - Also Reset all BT and Wifi settings (PITA) to no avail.
Is it possible to get a confirmation that the issues are looked into by HMD Global? - (Nokia mobile care app Support Chat is useless).
I love the design, battery life and the near stock android, frequent security updates, etc - but this is a deterrent for buying Nokia from HMD Global - because it shows HMD's commitment to solving issues with their products.
Please - look into (and fix) Bluetooth audio issues.
