I think Android or Samsung should implement autoconnect settings for devices. I can now see the problems if you have so many blue devices connect and disconnect while they are on all the time.
Hi, Welcome to the Samsung Members Community Canada. Please perform the reset Network Settings on your device and check if it works fine.
Go to Settings>> General Management>>Reset>>Reset Network Settings>>Reset settings.
This will reset all network settings, including those for Wi-Fi, Mobile Data, Bluetooth. Restart the mobile if necessary and check if it works.
Have the ability to select priority devices and an alert that pops up asking if you would like to switch. I have connected my devices in the order that I use them in headset first then truck but it still just connects to the truck instead of staying connected to the headset
