A51 Bluetooth issues

[YousefOmar]

Hello,

I've always enjoyed my Samsung smart phones, but not my new A51. I have a serious problem with bluetooth. Bluetooth connection keeps disconnecting and/or stuttering. I have a feeling its software is buggy. Has anyone faced this issue and if yes, do you know of a solution? I have updated the software to the latest version.

** Further updates (4-Feb-2020): today while playing an audio book on my bluetooth headset (Samsugn Level U), voice disappeared and I could only hear noise; I had to restart the phone to resolve the issue (back to Windows 98 theme); I hope Samsung can resolve this asap. It is a serious issue.

** Update (10-Feb-2020): i have just installed the update A515FXXU2ATA8/A515FOJM2ATB1/A515FXXU2ATA8 size: 351.39 MB (dated: Feb 1, 2020). will start testing and provide updates in a few days. 

** Update (14-Feb-2020): after a few days of testing, I can confirm the Bluetooth issues no longer exist. I have been playing Bluetooth audio and no disconnections or stuttering occurs. 

Thanks,

Yosuef

I think that for now is not going to be a problem. December security update is very new for android.

8/10 android phones do not have new security updates and people stil using it.

I hope that Samsung is working on a fix. For now that is your only option, do downgrade, skip SL6 update and to wait for a brand new update with fix.

I don't have the phone yet and I wait for a fix before I can buy it.

Or I will buy an other brand.

It will be the best. I do not recommend A51 to anyone yet.

Hiya, yes I can confirm that beta1b   solution on page 13 did do the thing for me.

Took a while to dicide to make the effort but I'm enjoying now the full function of BT Music without interuption.

I've SM-A515F PHN (Netherlands) model.

- Downloaded the old firmware On Sammobile from 15-December: A515FXXU1ASKJ A515FOXM1ASKJ

- Downloaded and installed Odin3 (Same site has it and instructions)

- Backup device

- Removed SIM & SD card

- Entered Loading menu (Power down. Vol-up & Power together, select bootloader)

- Flashed with old firmware.

- Going to setup menu with less config as possible. NO WIFI !!!!!

- Entered Developer Options. (In telephone info / Software .. / tapping 7x Buildnr.)

- Disabled automatic update system (In developer options below Telephone Info)

And

- Restored backup, and a lot of manual configuration.

But it was worth the time.

Think I'll look back here in a couple of weeks and see if the new firmware will solve the issue. Until then no updating the firmware !!

@Ice-Rabbit
Super!

I had only problems with update notification. I did not helped to disable update in developer mode.
I killed Update processes in developer mode. And for not showing again, I bought Package Disabler Pro for Samsung on Play store.
I this app I disabled: Software Update, System Update, Software Update (anotherone) and Dynamic System Updates.

Notification does not show up. If I reboot the phone, I must only to kill the processes again in developer mode.

I hope it helps someone.

Stil waiting for official fix.
