From the link it looks like they are launching unexpected February security update so there is a hope it will arrive with some fixes.
If someone get update and install it, please test and writte if there are any fixes
The patch A515FXXU1Axx6 is breaking the BT on the device. Don't install !!!
Wait for patch A515FxxU2Axx8 to be released in your reagion. This is now (5-feb-2019) released in Russia...
just bought the A51 5 days ago, having the same bluetooth stuttering issue i thought its only on my unit lol,
im from Indonesia.
i suggest everyone to write error reports on their Samsung Members app so the samsung devs will read and acknowledge, that there is an issue with bluetooth on the A51.
or open the bluetooth settings, press the three dots on the top right and select the "Contact Us" option and write the error reports there.
Today I got an update from A515FXXU1ASL6 to A515FXXU1ASL4. I don't know if this is a downgrade because they mentioned many bug fixes and camera upgrade, but I can confirm that bluetooth problem is gone. Tried it with wifi and GPS on, all stuttering problem gone. Will test it more.
As of Friday February 7 an update came that solved my bluetooth stuttering connection to Mitsubishi ASX hands free and audio system. Did a half an hour tour running in the same time navigation with Waze, Dash cam HD filming ahead, and YouTube music via mobile internet. Without any interruption.
Facing exact the same problem. Since installation of update A515FXXU1ASL6/A515FOXM1ASL6/A515FXXU1ASL3 bluetooth connection keeps stuttering while playing sounds/music.
Music works fine without bluetooth, so it's not an app issue. Worked fine befor the update, so shouldn't be a hardware issue either. Any help / information about update are appreciated.
German chat support is not helpful, obviously they are not yet aware of that issue.
