All,
I was pretty curious to try the new screen tech since the launch event, today i got the device, enabled frame rate monitor on developer settings to see the LTPO in action, contrary to what they said on launch event the screen switches back and forth only between 60 and 120hz , 120hz during scrolling , 60hz when the screen is static without any input. It doesn't go all the way as low as 11hz
Wondering is this the right way of implementation , members please share your findings or information related to LTPO here to discuss upon

read them as soon as andrei published it, would love to see his deep dive into the new panel in s21 and see what benefits it brings to the equation

Ah fair enough, he's comparisons of the two models are always worth reading! I did find the bit I was referring to if that helps. Basically the OS can't recognise the lower refresh rate but they are there.
'One problem (from our perspective) with this LFD mechanism is that it is seemingly completely transparent to user-space, so there’s no good way to verify that it’s active or working - the OS simply states that you’re either in the 120Hz or 60Hz VRR modes, however with LFD on top the actual refresh rate can be different. One way to verify this externally is simply to measure the end-result that the new panel technology is meant to bring to the user: lower power consumption. It’s also here that we encounter some of the quirks in Samsung’s implementation.'
Will be interesting to see if the adaptive rate works in lower light unlike the note!

That's the crux, whether it works or not we are limited to either 60 or 120hz on os level. Hope there is a way where this can be monitored more precisely via some workaround
This app seems to report (and limit) refresh rates other than 60 and 120hz, but I don't know how if it's not exposed by the OS.

Those refresh rates (e.g. 48hz and 96hz on Note 20 ultra) are actually exposed on OS level. If my understanding is right on the way that current android system works, S21 ultra implementation is probably the same to note 20 ultra with the addition of10hz as the lowest in the predefined set of refresh rates.
I love this phone, but there is one huge annoyance, there doesn't seem to be a way to make the screen actually run at a sustained framerate.
I have it set to 144hz in the menu, but it routinely drops to 60fps or 120fps depending on the app
This normally isn't a big problem, except nova launcher only runs at 60fps and so scrolling the app drawer is incredibly bad.
Pokemon Go also only runs at 60fps...and since the game operates at 1/2 vsyn, the effective fps is only 30, which is atrocious compared to the 72fps it runs at on the ROG6
Don't confuse Screen Refresh Rate and Frames Per Second. Totally different things.

I mean... Not really
Obviously the screen always runs at a refresh rate of 144hz because it isn't a VRR display(as far as I know that doesn't exist on phones)
So what you are changing in settings is always the frame rate that the phone is rendering at.
Your phone should ALWAYS be rendering at the frame rate you select in the settings menu... But this phone doesn't seem to do that, and it's annoying because it makes the usage experience worse than every other phone I have

Most of the reviews I've read/watched confirm what you've said. When you set 144hz, it runs that way in the default launcher and all the menus, but when you open certain apps, if they don't support 144hz natively then they just don't run at 144hz. The reviews seem to indicate that the developers of said apps need to enable support for 144hz.
So I was poking around the settings, and entered developer mode. There's an option to force the screen to stay at 144hz at ALL TIMES. It's called LOCK REFRESH RATE. I was able to confirm this works because there is also an option to SHOW REFRESH RATE which displays the screen refresh rate in the upper corner of the display. Before I locked the refresh rate, I used the show refresh rate function to view the refresh rate using different apps. In the phone menus, and app drawer, and google feed, etc the phone would remain at 144hz. But when opening some apps like Chrome for example, the refresh rate would drop to 120hz, etc. However, when I LOCKED the refresh rate in the dev options, the screen refresh rate stayed at 144hz in EVERY app and scenario I was in. It does state that this will drain your battery more rapidly when selecting to lock the refresh rate in the developer options. FYI
Hi everyone, I have recently got an Oppo Find X3 Pro. I immediately realized that the keyboard works at 60 hz and not 120 causing lag in writing, and on social networks with autoplay videos it often goes at 60 hz and not 120hz .. is there any way to fix? otherwise you just have to sell it.
Thanks
Is it so important for you to have 120 Hz where they are not really needed?
On the video in social networks, most likely 30 Hz, maximum 60, why do you need to watch them in a single 120? What would the battery drain faster?
Laughter about the keyboard. If there is no 120 Hz on the keyboard, I will sell the phone. It's just cosmically funny.
the 60hz keyboard is real **** .. if it makes you laugh you should get a Nokia 3310 and use that. In any case I found a bug that with a white theme the keyboard works at 60 hz while with the black theme it goes to 120hz without problems .. and then in any case it is wrong to manage the panel from the software since the display should ALWAYS work at minimum hz and as soon as you touch the panel it should pop at 120hz like galaxy s21 ultra. It shouldn't be separated by app causing lag of all kinds. Now I also upload a video that demonstrates it!

The phone adjusts itself adaptively. If the video is 60 Hz, what's the point of displaying 120 on the screen?
This is called optimization, not wasted use of the phone battery.

It is called optimization if it does not cause lag .. the video must go to 60hz but the rest of the scrolling must not go to 60hz but must remain at 120hz as ON ALL the top range, example: Xiaomi mi 11, s21, Oneplus 9 pro etc .. none of these have ever given me problems of this kind. And in any case it does not justify the fact that the keyboard works at 60hz with a light theme and with a dark theme it works at 120hz .. it is clearly a bug and the poor optimization of details. In any case if there is a mod to always bring the joke to 120 hz as on oneplus otherwise you can also leave it alone to comment. Thank you!

Do you own all the flagships at the same time? Mi 11, S21, OP 9 Pro? I doubt it...
So basically you want to have lets say video played at 60hz on the top of the screen but rest of the view should be working 120hz(like YT app)? None of the above manufacturers have such technology implemented to support different screen refreh rate on various parts of the screen. If you feel im wrong - please share the proof.
Besides what is the the problem with keyboard working in 60Hz? Are u really typing faster than 60Hz?
Stop moaning, sell the phone, buy samsung or whatever else u like.

Maybe you don't understand what I mean. I do not want to see the videos at 120hz, but as on all the top range that I have tried and had for a few months example mi 11, s21, oneplus 9 pro, during the scrolling if you meet a video on social networks it should not go to 60hz otherwise it causes scrolling lag for every video you encounter and is annoying. The keyboard that goes to 60hz is an absurd annoyance because writing fast you can see the difference I was used to with the other tops. Then here we talk about dynamic refresh rate from 5hz to 120. But seeing even if you stay still on the home screen or on a photo, the display always works at 120hz does not go down .. but only on unsupported apps it drops to 60hz but not because it is dynamic but because those apps are not fully supported. Anyway, let's finish it here if there is a way to force 120hz on all apps well, otherwise I will sell it and take back s21 ultra, which, however, should not interest you. Thank you
Hey all
This is for the people for non root but I think you can use it with root too I found this solution because i want to keep my OnePlus 10 pro without root but still wanted to have the benefit of forcing 120hz to get rid of the switching what causes lags sometimes and everything can be downloaded from here with a video that it works ans how it works enjoy

^Good to know! Cheers
Also there is an app call auto hz
it works, thanks so much, it was driving me nuts
It doesn't make sense to always force 120hz when you have an ltpo screen. It's best to leave the refresh rate high and it lowers itself to 10,5 or 1hz

true, but op's system makes the phone really laggy in apps that show video. i.e instagram
so it's more of a temp solution
Whenever I go into games or other social media apps my refresh rate goes down to 60hz but when I'm using settings and other system apps refresh rate is at 90hz, is somebody else facing the same issue? Can you tell how to fix it?
Refresh rate is in the corner
From what I've noticied, the 90Hz refreshrate only works on apps that work in 90FPS. If the app is stuck to 60FPS, then it'll force the refreshrate down to 60Hz
But why is it refresh rate going down in call of duty
Not every app supports 90hz.
Call of duty is supposed to support because it is a "popular" gaming app, and gaming apps should be able to support 90hz
did you consider the fact the processor just doesn't have the horsepower to run cod on 90 ?
a lot of phones default to the lowest fps when using apps , not the phones fault but the way the app is coded
