[26/NOV/21] BUKG Android 12 bugfix update

[ironass]

Only 11 days after the initial release of stock Android 12, Samsung have begun rolling out their second official stock update of Android 12, One UI 4, for the S21 series of international devices.

With a Build date of just 3 days ago, it would seem that this is a bugfix update.

Initially, as always, this is a staged rollout to the non-carrier branded, stock Samsung CSC codes first.

The Galaxy S21 international devices that will receive this update are...

• S21 5G model SM-G991B
• S21+ 5G model SM-G996B
• S21 Ultra 5G model SM-G998B

This latest release replaces the previous G99*BXXU3BUK8 build on the international devices.

It is a FOTA, (Firmware Over The Air), update and you can check... Settings > Software update... to see if it is available for you. Alternatively, you can connect to the Samsung PC suite, Smart Switch and check via that.

System information

The update = G99*BXXU3BUKG

Download = 330.59MB

Build date = 23 November 2021

Release date = 26 November 2021

Camera version = 12.0.00.83 (no change)

One UI version = 4.0

Android Security patch = 01 November 2021

This is the 21st stable update for the Exynos model in 305 days. Average = 1 update every 15 days.

TOP TIP: Wipe the phone's cache partition and use the Galaxy App Booster after updating.


(N.B. This post will be updated as more information becomes available)

I must say that I am impressed with the battery life on this BUKG update.

Normally I do not comment on battery life until the phone settles down after 2 or 3 charge cycles but this first charge since updating with 75% used and no Power saving is looking good. Certainly as good as Android 11, if not better. Am really liking this BUKG update so far.

Samsung has increased their staged roll-out of BUKG, today (30/NOV/21), to these countries/carriers...

No update yet unfortunately. One UI 4/Android 12 is quite buggy in my experience.

I have to say that neither the first stable Android 12 update, BUK8, or this latest version, BUKG, have caused me any major issues apart from uninstalling a couple of my usual apps that their developers had not yet updated for Android 12.

My gut feeling, judging from the slow roll-out this time, is that Samsung may slap the December Android Security patch on this build and call it BUL? and carry on rolling it out thereby killing 2 birds with 1 stone. However, who knows with Samsung!

AT&T just rolled out BUKF, still with 1 Nov security patch.

I've had several system crashes. Managed to get 3 last night on the same website.

No news on Vodafone (VOD), O2 (O2U) or Three (H3G) updates yet.

Do I assume correctly that no one with a U. S. unlocked S21 has received the update?

Thanks. Meant to post to your other thread.

Samsung are pushing ahead now with the roll-out of this bugfix firmware, BUKG, and have released over 50 updates for devices for countries and carriers in Europe already.

Three network carrier branded phones, H3G, are now the only ones still waiting on it in the U.K... as usual.

Looks like we will be in for another update shortly as Samsung will need to roll out the December Android Security patch in the near future.

The battery life on mine has been pretty good since the update, too. However, I was already getting 3+ days use between charges. S21 Ultra 5G

People must not use the phone at all to get 3 days on a single charge!? I have never ever experienced over 12 hours of battery life from any of my phones.

Over 4.5 hours, if you look at the screen on time. I do not play games on it, mostly just calls, text messages, a few pics and lately some internet Christmas shopping.

AT&T just rolled out BUKF, still with 1 Nov security patch.

So did Verizon. I was just checking and there was an update available. Release date said 12/6. However, it did not automatically download the way most of the previous updates did. Installed BUKF last night and then ran Good Guardians Galaxy App Booster. Waiting to see if there are any improvements
