My Galaxy s9 keeps disconnecting from my bluetooth device I use for phone calls. Happens randomly, and phone goes to speaker phone. I've cleared my cache, turned off battery optimization, repaired the devices, and reset network settings. Any other solutions?
I have the problem - BT is unusable for calls at this point but fine for music. More details:
I use a JBL Flip4 for music and phone calls throughout the day. I also use a Jawbone earpiece for calls occasionally. For calls only the JBL (and Jawbone) recently started switching from the bluetooth device to the S9s speakerphone for apparently no reason. A couple of more points:
I've tried doing things like disbling my music playback app, wifi on and off, restarting the phone (of course) and nothing seems to help.
I have the same issue and so does a coworker I just spoke with. I have the Samsung Galaxy S10e. The sudden change from Bluetooth to Speakerphone happens from any Bluetooth device I may be talking on - my Jabra Evolve 65 headset at work, or my Bose Soundsport earbuds, or my Kenwood stereo in my truck. It says its on Bluetooth still on the phone, but is clearly on Speakerphone. My coworker said it will switch back if he presses Speakerphone, then presses Bluetooth again. So far this has worked for me, but I can already say this can or will become a safety issue at some point. I have also tried restarting the phone and exploring settings. I haven't found a solution yet...
I have a Galaxy S9 on Verizon and just installed system update 23, software version: QP1A.190711.020.G960USQU7ETG2 this morning and now have this identical problem with bluetooth headphones while on a phone call. The headphones work fine with music from the phone and while connected to a PC so I know the problem does not exist with the headphones.
Almost exactly the same problem here - don't expect any help from Samsung. I posted the same issue weeks ago and other than utterly useless level one helpdesk recommendations (did you reset your phone...that sort of inane rubbish) it's been nothing but the chirping of crickets.
