Often after a restart I lose my bluetooth pairings such as my watch and headphones. When I try to reconnect
it does not find these devices. It takes multiple attempts
Any one have any ideas?
Have you tried wiping the cache partition of your device and resetting your bluetooth networks?
1. Turn off the device.
2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
3. When the Android logo displays, release all three keys.
4. An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight wipe cache partition.
6. Press Power key to select.
7. Press the Volume down key to highlight yes, them and press the Power key to select.
8. When the wipe cache partition is complete, Reboot system now is highlighted.
9. Press the Power key to restart the device.
I went through all of these steps on my Note 9 with a factory support person logged in.
Also turned off the nightly restart.
After a few days was back to the symptop of google assistant getting less functional, requiring restarts.
Within a week it's happening again (bluetooth setup lost on restart)
This time, before the manual restart, I opened the messages app and it popped up a warning that network connection was lost. I've got both carrier and solid wifi networks operating with no interruption, so it's the phone itself.
After the restart, all of the bluetooth configurations were wiped. On re-pairing, Smart Lock asked if I wanted to use the device as an unlock device, so it obviously didn't hold the device setup.
I just started having the same issue yesterday. I never experienced this before now. This is unacceptable for production OS releases and so is asking customers “Have you tried...” how about you geahold of your devs and find the Root cause and fix it. Or pay me and I’ll do it for you seeing as how it seems that you’re doing a whole lot of nothing to address the issue.
So I don't recall where I found this but what worked for me was to search "reset network settings" in the settings menu. I then simply reset my networks which included cellular, wifi and bluetooth. What wasn't great was losing every wifi connection I ever had and still used but it did allow me to start fresh with my bluetooth devices and after restarting several times it to have worked. So far I added 9 devices I use regularly from headphones to speakers to input devices and have restarted 3 times with good results. My devices connect automatically again now whereas before even after adding them every time like new they wouldn't ever connect with me manually selecting them.
