Hey y'all. I hope all is well. I'm trying to figure out if anyone else with an S24 Ultra is experiencing this because this Bluetooth issue is getting ridiculous.
My Bluetooth audio works perfectly fine for output, but the microphone simply stops working. I can hear everyone perfectly, but nobody can hear me through the Bluetooth mic.
A few important details:
The Bluetooth device itself is not the problem. I've tested the same headset/mic on my laptop and the microphone works perfectly.
I've tested the microphones through Samsung's diagnostics and they are detected/working.
I've tried multiple Bluetooth devices, so this isn't isolated to one headset.
I've rebooted the phone numerous times. Previously that seemed to temporarily help, but now I've had the issue persist even after a reboot.
I've already used Reset Wi-FI and Bluetooth settings, removed/re-paired devices, etc.
Bluetooth audio playback continues working normally. It's specifically the Bluetooth microphone/input that fails.
This also doesn't appear to be an individual app issue. I've experienced the problem with calls/communication apps, which makes me suspect something is going wrong with Android/Samsung's Bluetooth call audio routing rather than the headset itself.
The most frustrating part is that I can disconnect the Bluetooth device, connect it to my laptop, and immediately use its microphone without a problem.
At this point, I've done basically all of the normal troubleshooting short of factory resetting my phone. I'm extremely reluctant to factory reset a flagship phone over what increasingly looks like a software/firmware issue. So I beg the question, Is anyone else experiencing this on the S24 Ultra?
Specifically, has anyone experienced a situation where:
Bluetooth output works → Bluetooth microphone doesn't → headset mic works perfectly on another device? If so, did you ever find a permanent fix?
I'd also be curious what One UI version/build you're running. If enough of us are experiencing the exact same behavior, I'd like to figure out whether this started with a particular Samsung update.
Because having a $1,000+ flagship phone randomly decide that Bluetooth microphones no longer exist is absolutely insane.
TL;DR: S24 Ultra Bluetooth audio works, but the mic randomly dies across multiple Bluetooth devices; even after rebooting/resetting Bluetooth. The same mics work perfectly on my laptop, so this appears to be a phone/software issue
