Change - Manual Shutdown via the Bluetooth button is no longer immediate and will shut down some resources first. Bug - Bluetooth LE on Oreo had interface leak (if you were killing it by any method) that would eventually require a reboot. Bug - A2DP Trigger on Oreo could crash. Change - Bluetooth scanning frequency on LE was too high on Android 6,7 or Legacy mode on Android 8, some phones might have rejected the request. Enhanced - Shutdown now shuts down cleaner (not visible in recents list) This is not released yet but should be shortly after I do one more sanity check. Note: You should NOT kill the app while connected or while scanning or you WILL cause a leak. There are 32 "LE Bluetooth" interfaces in the system. You lose one every time you kill it. Reboot cleans it up. Not sure what leaks may occur on non LE. This is why I changed the shutdown button to not immediately shutdown. So use the button or enable Auto Shutdown and it will safely kill itself. Regarding the scanning frequency I expect users to not see any change, but in case you do I do have a backdoor debug mask to put it back the way it was. P.S. Samsung S8 phone (4th phone) on the way to extend testing coverage. I don't do$15 Walmart phones because I try to rotate through them as my daily driver (primary phone). I might break even by year 2020.
