[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Messmaker43:
Hello,

I installed the latest build and my Bluetooth is not working correctly on my G930F.

Flash was done via Install in latest TWRP from internal memory, formatted and wiped System, Data, Dalvik and Cache.

OEM Unlock was enabled and ADB also.

I tried a Stock Rom (PDA/AP Version G930FXXS3ERL7) in between and it worked without any errors.

This is what is currently installed from here:

https: //samfrew.com/download/Galaxy__S7__/jibO/DBT/G930FXXS3ERL7/G930FDBT3ERK3/

(PDA/AP Version G930FXXS3ERL7) now LOS15.1 10.01.2019

BL Version G930FXXS3ERL7

CSC Version G930FDBT3ERK3

MODEM/CP Version G930FXXU3ERHC

Problem:

Bluetooth does not pair only after multiple tries, says "No communication possible"

If it pairs it disconnects randomly after some time or not

If I try to play audio when there is a connection the audio stutters/lags like some kind of buffer problems

Logcat extract stuttering/lag problem
