[OnePlus 8 Pro Questions & Answers] crispy-cat:
How can I make my phone save screenshots in PNG rather than the horrible JPEG? I've rooted with Magisk and I'm aware of a module for the OP 5, but that doesn't work on newer phones. What other options are there?
[OnePlus 8 Pro Questions & Answers] dlads:
Screenshots aren't bad quality for me, if I send one over WhatsApp it is but that's due to it's awful image reduction.

It should be native to your screen resolution and as you can see from details of the one I've posted, it actually is.

If you want to convert you can but there should be no need to.
[OnePlus 8 Pro Questions & Answers] crispy-cat:
I want my screenshots to be lossless. Lossy JPEG makes editing very hard and leaves visible artifacts.
[OnePlus 8 Pro Questions & Answers] dlads:
Editing? Screenshots? Sorry man I don't see why you would need that level of detail from a screen grab.

It's possible that there may be a way to edit a value somewhere to make it higher quality but I'm not sure where that would be.

Why don't you decompile the magisk module your were referring to and see what it changes.

Or could you maybe record the screen and take images that way? Not sure if it works be superior to normal screen shots though
[OnePlus 8 Pro Questions & Answers] crispy-cat:
I want to make some Android tutorials for my site. I always reduce the colors and downscale rather than using JPEG.

I have no experience at all with developing Magisk modules, and from what I've read it relies on something that isn't available in later versions of Android.

Recording the screen just outputs the same horrible lossy image.
[OnePlus 8 Pro Questions & Answers] voythas:
Use Renovate Ice, Magisk Module. Once you flash it, you'll have screenshots in PNG
[OnePlus 8 Pro Questions & Answers] crispy-cat:
It works! May JPEG rest in the 2000s; I have 256GB at my disposal! I'm a little disappointed in the fact that Renovate Ice isn't FOSS, but it works.
[Samsung Galaxy S21 Themes, Apps] Corlan:
WIll be interesting to see if this makes much of a difference. With the S21 touted as having dynamic refresh rate adjustment, it shouldn't be needed, in theory.
[Samsung Galaxy S21 Themes, Apps] tribalfs:
You got the wrong theory.

It's not the first to have the adaptive refresh rate, note 20 ultra is. Been using this on note 20 ultra .

Though refresh rate is adaptive, phone is using the highest refresh rate (i.e. 120hz) atleast 80% of the time.

Setting the max to 96hz definitely consumes less battery than 120hz.

And this is not only what you can do with this app.
[Samsung Galaxy S21 Themes, Apps] Goku1992:
One question: us the 60hz also adaptive? Goes down to 10hz when not in use?
[Samsung Galaxy S21 Themes, Apps] tribalfs:
Sorry your question is not clear to me.

But if you are asking for smartphones with standard refresh rate (i.e. 60hz), I think they are all on a single 60hz refresh rate (i.e. fixed). I have not known any which can go lower than 60hz, moreso on the capability to go as low as 10hz. In fact, the S21 Ultra is the only smartphone capable to do so as of the moment.
[Samsung Galaxy S21 Themes, Apps] Goku1992:
Sorry. On the s21 ultra does the 60hz mode is also adaptive?
[Samsung Galaxy S21 Themes, Apps] tribalfs:
Sorry I don't know yet.

But if we based it on the existing implementation of Samsung in Note 20 Ultra's "standard mode", it is not lowering down to 48hz (the lowest refresh rate it is capable) when the screen is idle or if it has static content or even when the screen is turned-off or in AOD.

If fact this is true even in Adaptive Mode - Samsung actually (and strangely) sets it to the highest refresh rate (120hz) when in AOD or when screen is off. Watch closely this video. This is the reason why this app includes a "Screen off refresh rate mod" to override this behavior.

Not sure though if this will be the same for S21 Ultra.
[Samsung Galaxy S21 Themes, Apps] Goku1992:
Mate i will try when i receive my s21 ultra. But logistic is busy there, should have received it yesterday... Hope tomorrow...
[Samsung Galaxy S21 Themes, Apps] tribalfs:
Thanks, mate. Will standby for your update.
[Samsung Galaxy S21 Themes, Apps] minhgurluver:
I'm running into the following error while trying to set up the ADB on phone using my laptop:

adb: device unauthorized.

This adb server's $ADB_VENDOR_KEYS is not set

Try 'adb kill-server' if that seems wrong.

Otherwise check for a confirmation dialog on your device.

I didn't see any popup requesting permission on my phone. Any advice?
[Samsung Galaxy S21 Themes, Apps] tribalfs:
Try to do the following:

Disconnect USB > Turn off USB debugging > Revoke USB debugging authorization > Turn-on USB debugging

You can then resume to procedures described here.
[Samsung Galaxy S21 Themes, Apps] Goku1992:
Sorry mate my phone havent arrived till now :/ eagerly waiting :/
[Samsung Galaxy S21 Themes, Apps] tribalfs:
No worries, mate.

Take your time. It will arrive soon! :)
[Samsung Galaxy S21 Themes, Apps] Goku1992:
Ive ordered via Samsung.de... Dont know whats wrong... Support isnt good
[Samsung Galaxy S21 Themes, Apps] tribalfs:
I'll check that.

Can you share screenshot of the app showing the upper portion?

If you disable screen off mode, what is the screen off refresh rate shown?

Thanks.
[Samsung Galaxy S21 Themes, Apps] nxneko:
I have identical behavior so seems like its just s21ultra tweak needed in general.

(Limited it to 96hz for now though thank you!)
[Samsung Galaxy S21 Themes, Apps] tribalfs:
10hz is not enabled in the system.:confused:
[Samsung Galaxy S21 Themes, Apps] Goku1992:
Thank you for this ppst and also the upper post. Can you use 60hz and it is going down to 48? Sadly my ultra should have arrived one week ago but Samsung.de have big shipping problems so likely i must wait another week :/
[Samsung Galaxy S21 Themes, Apps] Goku1992:
Think it will need an update. The note 20 uktra had the same problem at the begining and now it goes down to 48hz when you dont touch the screen
[Samsung Galaxy S21 Themes, Apps] nxneko:
When its set to 60hz, it just stays there. Regardless of Adaptive or standard. When you re-apply adaptive mode, the app no longer allows 48hz as lowest refresh rate, only 60 as minimum when you set 96hz or 120hz as max refresh. I have not seen 48 outside of screen-off which is reporting at 48 when toggled instead of the 60hz s21u selects as its screen-off Hz.

You are not missing too much, as I hear the os release is still pre-release technically and full release OTAs are around corner. There are many display bugs still.
[Samsung Galaxy S21 Themes, Apps] primarina:
Can we have widget for Refresh Rate Mods(Constant High, Adaptive, Standard) thank you
[Samsung Galaxy S21 Themes, Apps] tientom:
i used two day trial, and if i want continue use, then i need pay it, right?
[Samsung Galaxy S21 Themes, Apps] tribalfs:
Wil check if we can add in the next version.
[Samsung Galaxy S21 Themes, Apps] tribalfs:
Only the premium exclusive ones. You can still continue using with the free features.
[Samsung Galaxy S21 Themes, Apps] primarina:
ill be waiting. thank you
[Samsung Galaxy S21 Themes, Apps] tientom:
Keep selected refresh rate mode on power saving mode[1]

- On devices with One4 or lower, GMH will automatically apply a workaround to bypass 60Hz limit on Power Saving Mode.

- Need extra steps on OneUI5.* except when using magisk and lsposed(experimental). Test it first --> Does the above feature require a fee?
[Samsung Galaxy S21 Themes, Apps] tribalfs:
It's indicated in the post.
[Samsung Galaxy S21 Themes, Apps] Goku1992:
Pre release? But today was the official Release in germany :D thats strange :D
[Samsung Galaxy S21 Themes, Apps] tribalfs:
It's not the app. It's the default behavior,.
[Samsung Galaxy S21 Themes, Apps] Goku1992:
Think this Update is coming eaelier than my phone lol. And i have preordered it on official Samsung website and they told my "preorder now and get the phone 3 days earlier than Release" 🤣🤣🤣
[Samsung Galaxy S21 Themes, Apps] Goku1992:
Here in germany Samsung dont know how to ship lol🤣
[Samsung Galaxy S21 Themes, Apps] russellcausier:
Keeping an eye on this thread as also using it for 96hz but goes no lower than 60 only on screen off it goes to 48hz,will there be an update so we get 96hz to 48hz?
[Samsung Galaxy S21 Themes, Apps] Goku1992:
It should go as low as 10 on the s21 ultra...
[Samsung Galaxy S21 Themes, Apps] russellcausier:
Go as low with or without this app?on screen refresh monitor goes as low as 48hz that's only lockscreen and couple of video apps rest is 96/120 to 60hz!won't lower to 48hz when screen isn't touched only 60!so only benefits at the moment with this app is 96hz and lockscreen at 48hz without this app 60hz in lockscreen only and 120 and 60 hz when not touched,so I'm not sure if this app is really worth having at the moment can't tell if battery better with or without it??Will 48hz on the lockscreen be significantly better than 60hz on lockscreen?
[Samsung Galaxy S21 Themes, Apps] russellcausier:
Yeah I'm in the same boat as you then,hoping the developer can alter this app to drop at least to 48hz when phone not touched!not sure how much using 96hz and 48hz with screen off saves battery with this app but seems to be working well they are the only benefits of this app would be amazing to drop it to 48hz,yeah they don't tell you anything about it dropping to 10hz and I've had refresh rate on monitor all the time only gone as low as 48 on syncler app but Netflix stays at 60hz.
[Samsung Galaxy S21 Themes, Apps] russellcausier:
T

That's strange,didn't think you could alter that screen off rate at the bottom thought it was just stuck to the lowest!that power saving trick still works,power saving mode on with adaptive and 48hz lockscreen 👍🏻
[Samsung Galaxy S21 Themes, Apps] russellcausier:
Yeah will he see this or do we need to tag him to ask?,this app is top drawer just needs the 48hz with screen on not touching and will be fantastic,or if there's a possibility he can get it to go lower than 48hz for 21 ultra
[Samsung Galaxy S21 Themes, Apps] russellcausier:
@TribalF hi is there any chance of enabling lower refresh for s21 please to 48hz or lower when screen is on but not touching or even lower than 48hz on lockscreens please?fantastic app 👍🏻
[Samsung Galaxy S21 Themes, Apps] Goku1992:
The s21cant go lower... Only the ultra to 10hz but this is written into the display driver
[Samsung Galaxy S21 Themes, Apps] Goku1992:
No, but Samsung stated this 🤣🤣🤣 mine is also going from 120 to 60 if i do nothing... XD

No 48 :D
[Samsung Galaxy S21 Themes, Apps] russellcausier:
Sorry I meant s21 ultra that's what I have 👍🏻
[Samsung Galaxy S21 Themes, Apps] Goku1992:
Then yes it should go lower than 60 or 48 :)
[Samsung Galaxy S21 Themes, Apps] Goku1992:
But i thnik its a bug like the note 20 ultra the furst time... All in one the Software on the s21 ultra seems a bit "beta" like
[Samsung Galaxy S21 Themes, Apps] russellcausier:
Was there an issue with note 20 ultra refresh to start with?I've come from s20 ultra so new to me the adaptive
[Samsung Galaxy S21 Themes, Apps] Goku1992:
Yes the adaptive refreshrate wasnt working well. Now it does :)
[Samsung Galaxy S21 Themes, Apps] Goku1992:
Thanks for the ibfo mate, hope this fixes some bigs with the slow home Animation. It bothers me xD
[Samsung Galaxy S21 Themes, Apps] tribalfs:
The refresh rate switching while screen is on, touch interacted or not, is managed deeply by the android system. There are other factors that the system considers when deciding to switch refresh rate up or down other than the touch interaction. Currently have no good workaround on forcing to 48 yet. Current solution that I have overrides the behavior based purely on touch interactions but this can ruin experience on contents that better shown on higher refresh rate even though not interacted. I have yet to find a better workaround.

Let's hope that this will improve in the future ota updates.
[Samsung Galaxy S21 Themes, Apps] tribalfs:
In your screenshot, screen off mod is not turned on.
[Samsung Galaxy S21 Themes, Apps] russellcausier:
Thanks for the info 👍🏻 could you not force the refresh on the note 20 ultra when that first came out?so basically have to wait on samsung to allow it,then your app should be able to control it?cheers
[Samsung Galaxy S21 Themes, Apps] Xylvion:
any plans to update for 10hz refresh on s21 ultra?
[Samsung Galaxy S21 Themes, Apps] tribalfs:
not yet possible. not enabled in the OS.
[Samsung Galaxy S21 Themes, Apps] russellcausier:
So on the note 20 ultra is it optimised for 48hz when screen on but not touching?as it looks as though that's the case inside the app,so we gotta wait for samsung to optimise then you can see how low your app refresh rate can go?
[Samsung Galaxy S21 Themes, Apps] mtm1401:
Samsung's Note20 Ultra Variable Refresh Rate Display Explained (anandtech.com)

This article explains the refresh rates and the difference between the 60/120hz we see on the overlay (which I believe this app uses) and the 10hz figure quoted by samsung, which is at a hardware/driver level.

The only real way to tell if it is dropping below 60hz is comparing power drain, and at the moment the S21U power draw at 60hz and adaptive is very similar. You can see in the link below, that the adaptive refresh is working, as in low brightness (<40lux) where the phone is forced to 120hz mode regardless of content vs the reduced power consumption when in >40lux.

Investigating The Galaxy S21 Ultra New OLED Emitter: Huge Efficiency Improvements (anandtech.com)

Also when I use the BT Sport app on myS21U in full screen, the overlay drops to 48hz, so it does work, just app dependent (i.e. YouTube stays at 60), and the UI seems to default to 60hz unless told otherwise.
[Samsung Galaxy S21 Themes, Apps] russellcausier:
Do you think it's worth having this app at the moment with it not being optimized?only benefit at the moment is 96hz and screen off at 48hz other than that s21 ultra seems to drop to same 60 for YouTube an Netflix etc but other video apps dropping to 48hz,will this app cause any battery drain?rather than just keeping it stock for now?seems to have been fine on the battery so far
[Samsung Galaxy S21 Themes, Apps] mtm1401:
S21U Exynos here

I have the screen off refresh rate mod, and since the Feb update the phone seems to get stuck at 48hz when waking the phone, have to go to the toggle and bump up to max.

Doesn't happen every time, I'd say 3 or 4 times a day. Can provide a bug report if required
[Samsung Galaxy S21 Themes, Apps] russellcausier:
Same
[Samsung Galaxy S21 Themes, Apps] hsienjuen:
Hi, I've been using this app so far and it seems to work well for me on my S21 Ultra :). But the minimum referesh rate my phone goes down to when viewing static images is 60hz, and 48hz while viewing 24fps video.

Would it be possible to make the refresh rate go down to 10hz when viewing static images in a later update?

Thank you
[Samsung Galaxy S21 Themes, Apps] DontReuseUsernames:
Can someone please just clarify this a bit? Earlier posts mentioned "At a hardware level". To me that says that we don't have access to this, even with a custom ROM as this part of the LCD is a binary blob. However, I'd like to confirm this.

I'm interested in locking to 10hz for eye care. The human brain has a preference for 10hz so locking to this frequency would reduce eye strain, decrease battery drain and phone addiction. Pretty useful seeing as the only EINK phones out there are the Hisense Chinese phones riddled with spyware.
[Samsung Galaxy S21 Themes, Apps] Goku1992:
The 10hz minimum was stated by Samsung as lowest refresh but havent seen this... They stated if you watch photos it goes as low as 10hz...
[Samsung Galaxy S21 Themes, Apps] russellcausier:
Had 2 software updates since having the phone but still the same hz as we've been seeing,surely they would know people would check this seeing as though we can check refresh rates!!
[Samsung Galaxy S21 Themes, Apps] Goku1992:
Yes its strange... I think the best is if the videos on youtube go as low as 24hz (most of the youtube contet runs at) or 60 for the 60fps ones... Dont know think Samsung needs a bit time to tweak this
[Samsung Galaxy S21 Themes, Apps] russellcausier:
Yeah I hope somewhere people are bringing this to samsungs attention!👍🏻
[Samsung Galaxy S21 Themes, Apps] russellcausier:

V6.50 is up!:)
[Samsung Galaxy S21 Themes, Apps] russellcausier:
Great work thank you!!Will you let us know when it's possible to drop to 48hz and 96hz adaptive thanks again
[Samsung Galaxy S21 Themes, Apps] Melhisedek:
So how does it work?
[Samsung Galaxy S21 Themes, Apps] russellcausier:
At the minute it allows you to have it between 96hz and 60hz and also when your screen is off goes down to 48hz instead of 60hz so all in all saves you more in the battery department,eventually when samsung allow it this app may be able to swap to 96/120hz to 48hz or lower when screen on,here's hoping 👍🏻
[Samsung Galaxy S21 Themes, Apps] minhgurluver:
For some reason, the option to have the lowest refresh rate at 48 HZ disappeared for my S21. It's always there until I updated the version of the app. Do you know how to get it back?

I've updated to the latest and cleared data like it says,now it's back to 120/60 no 48hz?Where's the option gone to go lower to 48hz please?@tribalfs
[Samsung Galaxy S21 Themes, Apps] steelersmb:
Has anyone done and battery tests to see if this really saves any battery life?
[Samsung Galaxy S21 Themes, Apps] russellcausier:
I've deleted it recently and battery life seems better without it for me!deleted it because the latest version no longer went from 120 96hz to 48hz with screen on only 48hz again with screen off,not sure why!@adamlee2012 are you on the latest version and do you still have the 120/48hz screen on option?
[Samsung Galaxy S21 Themes, Apps] russellcausier:
That's odd as that was working for me but updated the app and cleared the data like tribalfs suggested and went back to 120/ 60hz
[Samsung Galaxy S21 Themes, Apps] naudmick:
I have the same behavior on my galaxy S21 exynos and my Tab S7, both remain with a lower rate of 60hz, so I removed this application. Besides, I didn't notice any improvement in the battery, so in the end this application is useless.
[Samsung Galaxy S21 Themes, Apps] russellcausier:
Yeah we got an update which finally brought the adaptive to screen on 120hz 48hz which was great then it said to update not long after and that option disappeared 🤔 so it's like trying to get back to the version one before this latest one but no response from @tribalfs
[Samsung Galaxy S21 Themes, Apps] tribalfs:

@tribalfs many thanks for this app, it's brilliant!

Just a suggestion, in one of your future builds, could you look at maybe enabling a plugin to Tasker so that any automation can be done?
