i bought the a51 about a week ago and i also have problems with bluetooth disconnecting and stuttering when listening to music. its realy annoying fix this asap samsung
I have the same bluetooth issue. I've been using Samsung phones for a long time but I'm disappointed now... A51 sucks, I can't connect to many devices or the connection is very bad. I hope Samsung will solve quickly this issue and do something for us.
A hard reset and disabling wifi makes is a little better. But wait for a real solution.
And the problems started after the update. Before update I could use it normally.
So DON't update immediatly. Check if the update is AFTER 1-feb-2020.
I have same issue too. After reset the bluetooth caches, clear data and disable the Optimise battery usage for bluetooth last night, my device worked well today.
To reset bluetooth caches and clear data:
Setting --> Apps -->tab on the menu (right corner) --> show system apps -->bluetooth --> Storage
click "Clear data"
To disable Optimise battery usage:
Setting --> Apps -->tab on the menu (right corner) --> Special access --> Optimise battery usage --> All --> Bluetooth
Turn off the optimised on Bluetooth
I've tried the solution from HoChingYUNG but it doesn’t work for me. My Samsung Gear S3 is freaking out and so am I. It constantly loses the Bluetooth connection with my Samsung Galaxy A51. The same happens with my Jabra Bluetooth headset. It is since the last software update. for me, in the Netherlands, that was this morning (February 5).
Samsung needs to solve this very quick, My Bluetooth devices including the most important devices like my watch and car-connection are unusable
