I have had a few issues with the bluetooth connectivity of my S23 Ultra. 

Firstly I am unable to take or make phone calls with my headset.  For instance, I can be listening to music or watching youtube through my headphones, but if I answer a phone call it switches away from Bluetooth, but still shows me the option to use it.  When I click on it on the phone screen, I can hear the audio from my headphones for a moment, before it switches itself back to phone audio. I have restarted my phone, and checked to make sure all of the settings are turned on my headphones via the wearable app.

Secondly, and even more annoying, is when I have one headphone in my ear, and the other in its case charging, and walk away with my phone, the audio from the only headphone I am using cuts out.  If these are standalone headphones, why is my audio chopping out when I walk away from the headphone that isn't even being used! I haven't had this issue with past Samsung headphones so this one doing it is really aggravating.

Any help with either of these issues would be greatly appreciated!
