My Galaxy 21 stopped playing audio via Bluetooth on certain devices. It wont play in my car at all for about a week. Yesterday it stopped playing in my JBL speakers. It works in my PowerBeats headphones still so far though. Be clear, IT PAIRS with no problem. Its just NO sound in certain devices. Both the phone and device volumes are all the wsy up so that isnt the issue either. ALSO Bluetooth is NOT listed in my app manager. So I cant clear the cache or anything.
Try this, Settings>General management>Reset>Reset network settings. Mind you, this clears all Bluetooth and Wi-Fi connections/settings and you will have to reestablish them afterward.
With the device powered off, press + hold power and volume up buttons until the Samsung logo disappears. Using volume keys, select Wipe cache partition, then power to select and confirm. After returning to the menu, use volume to navigate to Repair apps, and then power to select and confirm if necessary. This will reindex all apps on the device.
Ok at first i didnt do both in that order. I tried again and did both (cache wipe and app repair). Im in my car and it worked. Hopefully it stays working. Thank you very much.
Oh no! 😔 For all devices still, or just your car? Have you tried removing the device from your car settings and then trying the re-pairing process again from the beginning?
