Hi there,
actually I’ve noticed a bug which I want you to notice and work on it.
I’m using Oneplus wireless headphones with this phone.
During I’m using the wireless headphones when someone calls me and when I receive the call it automatically connect to phone’s speaker and not to the Bluetooth headphones.
I think this needs to be fixed as I can not put out my phone than manually change from phone speaker to Bluetooth headphones every time
How would Apple be able to do anything with a product not associated with Apple at all. If you aren't able to answer phone calls using this non-Apple product, you need to contact the manufacturer of the product.
I have multiple Bluetooth, non-Apple wireless earphones. I have no issues at all answering and engaging on phone calls through the headphones.
Do these headphones have an app in the App Store, which has settings for them? All of my Bluetooth headphones can be customized for feature use via an app the manufacturer offers in the App Store.
