Hi All,
Seems like Samsung has added some trick to their brand new S20 Fan Edition device, as previous S20 series devices.
= Galaxy S20 FE has a hidden 96Hz display mode=
With this 96hz hidden option you can restrict the adaptive refresh rate to work to 96hz allowing your phone to prolong battery life.

https://labs.xda-developers.com/store/app/sszb.s20.refresh
Also, seems that Samsung allows to change both refresh rate and screen resolution using Bixby Routines.
I am checking if these is true or how. But if someone knows better step-by-step how to, please let a comment and i will update this thread.

How to use:
Ensure that you are running in FHD+ or HD+ resolution (QHD+ does NOT support 96 or 120 Hz, only 48 Hz and 60 Hz)
Install the APK onto your S20
Launch the app; if you see a warning dialog "This app was built for an older version...", just click "OK" and ignore it
Grant WRITE_SECURE_SETTINGS permission to the app using ADB:
adb shell pm grant com.ray.customrefreshrate android.permission.WRITE_SECURE_SETTINGS
Tap on "Check Permissions"
The main UI should show, with the current refresh rate selected
Tap on any of the desired refresh rates to change to; it should apply immediately
Open up your web browser and go to testufo.com to verify the new refresh rate is in effect.
everyone says it is working. check and comment.
cheers.
and a BIG THANK YOU to DEVS who made this possible through all their hard work and dedication!!
This was the first thing I tried after setting up my FE. But upon testing it only changes the refresh rate to 60hz.

hi,
how you set it up?
meaning: did you used Bixby Routines to have medium power saver on with High Refresh rate?
then, did you used the app to setup the refresh rate default from 120 to 60 and then change the aps you need to use 96hz refresh rate?
cheers.

No. I just installed the app and selected default refresh rate to 96.

This does not work. Attempted to give permissions via adb. Still testufo site shows 60fps when you select 96hz.
Selected standard and high refresh in settings and selected 96hz on either setting. No dice.
Is there a reason they don't offer it for power saving purposes? Why is it 60 and 120 only

No, it does not.
I have the S20 FE 5G (Snapdragon) version here bought in germany from Samsung Store.
I used adb dumpsys display
It has only 60 or 120hz and also only FullHD+ resolution, not even HD+ but that is normal when the panel only has FullHD+.
So sadly this means your App does not work.
But I found a way to automatically switch between 120hz and 60 hz.
I use a Bixby routine to switch to standard refresh rate (60hz) when chosen apps are open.
This is working fine and changes the refresh rate automatically within 2 seconds after app opening/switching/closing.

Is there a way to activate it since it's only software wise? Or is this something only Samsung can do if they decide to patch it in as a hidden feature like the other S20s?
idk.
But the S20 FE has a different Panel then the S20 series.
So I dont think the panel can handle 96hz
Is there a way to enable quad hd resolution on this phone or this panel is not compatible?
The adb permission is not working I get a error message in adb
Thanks for the app, anyway I don't think the battery saved with 96 Hz would be so great
This app and any 96 Hz mode will never work with the S20 FE (5G) as the panel does not support it.
I already wrote this in post #8.
Has anyone tested this app? Does the compatibility check does not allow to change the refresh rate?
I checked the source of the app and I think that I can add S20 FE to list of allowed device. I don't own this phone (yet), so someone else will have to test.

You wanna pm me the modified apk and I'll try it.
Not working, tested with snapdragon version
it works for s20 fe 5g?
No.
Look at Post #8
I tried this over the weekend, unfortunately it does not work for 96Hz. I granted the perms through ADB enabled it through the option list but while verification it shows either 60Hz and 120Hz

Probably because 96hz will not synchronise properly with the screen (it supporting 120hz, 96hz is divergent)
, causing flickering, screen tearing and touch issues.
Hello sfu,
I alr set my display to 120Hz, but does it mean I am getting 120Hz on all my settings ??
If not, how do I force all the apps to get 120HZ?
Thank You.
Isn't it always 120Hz? Check with the app that display refresh rate. But the last time I checked, everytime it was 118-120Hz.

some apps revert it back to 60hz, like youtube, google photos, netflix. Recents apps page is 90hz
You need to delete battery app data.You will have yt and all aps on 120hz but after some time it reverts on 60hz and you need to delete it again.

That's troublesome though, is there any other way to make it permanent to 120Hz ???
Why it keep on reverts to 60hz?
That is the question for Poco.
I believe the idea is to keep battery usage to a minimum... Apps that don't natively make use of the 120Hz are switched back to 60Hz in favor or battery life. In short 120Hz is actually adaptive refresh rate.
I thought it was an adaptative screen freqency rate but actually, we only have the option to set to 60Hz or 120Hz. Only. Or did I miss something ?

According to the GSMarena review, F3 has variable refresh rate, it will automatically change between 60,90 and 120HZ. This guide will lock it on 90hz

So why in settings I only see 60Hz or 120Hz and nothing about 'switching' 'variable' etc ? :s

Just put it on high (120hz). It will automatically reduce to 90hz or 60hz depends on what shown on the screen and how you interact with the screen.
For example, when you're watching a website, reading text, it will automatically put back on 60hz. And when you touch the screen (for example, to scroll the website) it push back on 120hz
