the BRI after the September security update
Charging becomes very slow, originally it takes about an hour for 10-100
Now it takes 90 minutes to fill up

Been using TGY Variant since the S9, this is the first time I can remember not receiving a timely update. Also, does anyone know the differences between TGY and BRI Firmware? I've read their the same but I'd be surprised if that's the case.

My CSC is originally BRI and since flashed the TGY. I'm unable to come back to BRI as it seems like they are the exact same firmware - same md5.

Flashed Taiwan BRI update and csc still turned out as TGY.
For those still stuck at August Update on their TGY model, flashing the BRI will update the phone to September Patch.

Download Firmware from Frija and flash Via Odin.
Bro did u just dirty flashed it or did a back up and clean before flashing. I have 350gb of data so want to avoid flashing just over it. Also in UAE im getting 5g and everything is fine with the phone including battery life. Just Samsung pay is not usable. Please let me know if camera and any other improvement is there over tgy when comparing bri software.
Thanks

Not sure about any particulars for the moment. I have not done much with the Sept BRI Firmware. Hopefully others might know.
