Can't confirm bluetooth problem...new update worked fine on BT pairing to a Sony speaker regardless of screen timeouts or reactivations.

Yes, I follow all instructions. All background Apps are closed. I wiped the phone 2 times since the last update. Nothing helps

I have installed the FW 20180522 hoping to solve Bluetooth problems, but no luck, problems still persist.
I use three different device, and with all of them i get disconnection.
With the car the phone disconnect without logic, even with a call in progress.
With the headset I continusly get "device disconnected, device connected", even once a minute, but only when idle.

I tried also to disable battery optimization for Bluetooth. No way.

Very frustrating !

Did you strictly follow what stated here?

Summing up:
0) Consider updating your device to the latest firmware and performing a factory reset after that

1) Go to "Settings" -> "Background task clear"  and whitelist all your 3rd party apps wich need bluetooth to transfer data (i.e. samsung gear app, veryfit app and so on..). By doing that, they will be allowed to run in background even if the smartphone is in deep sleep state.

2) Go to "Settings" -> "Battery" -> "3 dots" in the upper right corner -> "Battery optimization" -> select "All apps" from the dropdown menu  and disable battery optimization for every bluetooth service app, as
- Bluetooth MIDI service
- BT Tool
- Bluetooth sharing

and for every app needing to use bluetooth to transmit data, as
- Phone
- Phone services
- Call management
- Phone/Messaging storage
- your 3rd party music player
- other telephone dialer apps
- fitness band apps and so on

3) Only if the previous steps doesn't solve your issue, also
- Go to "Settings" -> "Battery" and disable "Standby intelligent power saving"
- Go to "Settings" -> "Duraspeed" and and disable it.

4) Only if, again, the previous steps still don't solve your issue, also go to "Settings" -> "Battery" and set your device into "High performance mode"

Please follow these steps carefully

Just a info; i´ve got this problem with BT earplugs (Plantronics)  as well. It stopped when i changed to new earplugs with BT 4.1 system.

I have LEOPHILE ZERO Headphone, which is BT 4.1.
I have disable battery optimization for
-[b]Bluetooth MIDI service[/b]
-[b]BT Tool[/b]
-[b]Bluetooth sharing[/b]
-[b]Phone[/b]
-[b]Phone services[/b]
-[b]Call management[/b]
-[b]Phone/Messaging storage[/b]
- Microsoft Launcher
During long telephone calls the BT connection is stable, but I'm still getting "connection lost" and "connection successful" from the Headphone during idle. 
Sometimes I need to disable Bluetooth on the phone, and re-enable to get a stable BT connection with the phone.
No way to get a stable BT connection with the car.
