I think you should provide revised steps if users are unable to resolve the disconnectitivity issues.
A couple of times I reported this issues to Samsung customer care and they are also denied to repair or reset this headphones.
Later I have investigated and solved the problem using the below steps, I request all the users who have purchased this "Samsung level U" headphones and facing disconnectivity/auto re-connectivity issues with any phones.
Below steps are applied to all android phones:
1. Goto application in the phone settings.
2. *In the top right options menu select "system apps/show system"
3. In the search bar type "Bluetooth" to select Bluetooth system apps
4. Depending on device operating systems you will find 2 "Bluetooth" and 1 "Bluetooth MIDI Service" apps, in some devices you will find 1 Bluetooth app.
5. Tap on the app -> goto Storage -> "Clear Storage"
6. Repeat step 5 to all "Bluetooth" and "Bluetooth MIDI Service" app
Repair the Headphones with the android device and I hope you won't see any disconnectivity issues.
