Hello friends, how is the performance of your device's camera after the February update (G998BXXU1AUB3)? Do you still have the problem of overheating? What about the problem of camera lag and Video 4k 60fps lag? Are the problems solved?

I am just performing a factory reset right now...live.

One thing I find very interesting... is that it looks completely different from the steps that I went through on day 1... where I booted, did a smartswitch sync...

in the first couple of days I had all kinds of problems in getting my vodafone sim card recognised, and getting apps to start up etc.

One UI 3 is also looking very different right now, from what I have been using over the past 11 days. I am hopeful that I could find this factory reset and manual app installing of only the relevant ones now... could be a good choice... i will post my results in a day or two whether this changes my phone's performance or not...

Just took a screenie of my CPU Spy to see how my phone is performing in Deep Sleep which as I am sure you know, conserves battery and informs me if any apps are misbehaving. I do not use Battery Power Saving preferring instead to optimise apps that need it whilst giving apps that are in constant use, a free rein... Nova Launcher, widgets, email, Message, Whatsapp, Calendar, etc: I do use Adaptive brightness and Adaptive Motion smoothness as well as Auto brightness on the Always on but I am prepared to take a 10%-15% battery hit on it as I got fed up with, "Tap to show". Location services and Bluetooth are on 24/7.

CPU Spy shows how much time my phone spends in Deep Sleep when idle...

CPU Monitor shows the temperature and activity when my phone is idle...

Hope this helps.

I have the 512gb ultra and did a fresh start when i first got it, the batter lasts for about 30 hours with 6/7 hours screen on time.  Definitely recommend not doing a smart switch.

Normally, the device is cool in idle mode...But My S21 Ultra was severely overheated after using the camera for 10 minutes. My question is, was this problem solved after installing this update?

As per my earlier post... "What the update will not do, is rectify any issues caused by users apps and settings... no update can do that."

Check out the suggestions in this thread, regarding a Factory Reset and fresh install of apps and data as well as checking your apps for Android 11 compatibility.

I have returned my S21 Ultra and I no longer have this device. I want to know if the problem of overheating the device and camera lag has been solved? Do you suggest I buy an S21 Ultra again?

I do beg your pardon realme99!

I was confused as to who I was replying to. Earlier today, in reply to another user, I left the camera on for 10 minutes. It did drain the battery but did not run unbearably hot. I will try it again with a CPU temp reading at the end this time.

Unfortunately, my S21 Ultra, like some people, got so hot frame on the top of the device for 10 to 20 minutes when I used the camera that it burned my hand. My purpose in asking this question of the members was to know this problem has been solved with the update? Or it is hardware and cannot be solved. Thank you for your answer.

Just completed the worlds most boring 10 minute video, see screenshot...

The CPU temperature went from 28C to 35C and in no way can it be described as too hot. See screenshot...

Hope that this answers the question.

Best not to back up apps on Samsung Cloud either.
