[MOD] Disable brightness throttle for screen [9500/9505] - Galaxy S 4 i9500 Android Development

Edit: it's been discovered that the option mentioned in this thread has A built in shortcut already in display settings, so we no longer need this method. Thanks @Andrei for letting us know. Atleast by now we know that there is a setting that throttles actual brightness and can be disabled whenever needed.
FLASH IT ON YOUR OWN RISK
Needs a kernel with init.d support if you want the mod to stick after reboot
What is this mod for?
This mod disables the brightness throttling on the screen. Some people would have noticed the auto adjusting of screen brightness even if the brightness is set manually.
Where is the value being changed?
Code:
echo 0 > /sys/class/backlight/panel/device/lcd/panel/power_reduce
or
Code:
echo 0 > /sys/class/lcd/panel/power_reduce
Above is the location where the value is changed. "0" disables power save and "1" enables power save back.
How to apply this mod?
* Either run the attached script file via some scripting app
* Or simply run the attached flashable zip from cwm.
Note
*This mod can be removed by simply deleting the file "55disablepowersave" from init.d folder and rebooting the phone.
*This mod may increase the strain on your battery if used with higher brightness, since it disables "power saving".

Thanks, it should be noted that brightness throttling will still happen but on a much smaller scale.
Essentually, this allows users to avoid the undefeatable Power Saving mode in the Chrome and Stock browser, which will shift brightness up from the curve in light orange to the cuve in orange.

As you pointed out, this is only useful when brightness is set manually. When auto-brightness is activated, there is no throttle, except under prolonged exposure to the sun to protect the battery:

The value in "power_reduce" is 1, only if "Auto adjust screen tone" is checked in Display settings. Otherwise the value will be 0.
I dont see the benefit of this MOD
But thnx for trying

power_reduce mode is set to 1 regardless of whether auto brightness is turned on or off. Setting it 0 disables the throttling of screen brightness .

I can't find the zip.

Sorry to poop on your party guys, but that's the sysfs entry for auto adjust screen tone, it has nothing to do with the adaptive brightness controls.
This mod does nothing that can't be done via just checking the AAST checkbox in the settings.

Was waiting to hear back from you, one or the other way I'm sure you'll find a way.
Edit: yes it's the control in the display settings. Wondering this settings works on s4,i haven't seen any change in screen brightness with that setting enabled in s3.

I did some more analysis of the display behavior. Essentially, the adaptative brightness without power saving options is to fool regular gamma testing and make it look flat even though it isn't - again to conserve battery!
Using Average Picture Level patterns, to keep brightness constant across the greyscale, we can clearly see that the gamma is too high (2.4).
By reducing brightness as IRE levels increase, the display conceals the fact that brightness increases too slow across the full IRE spectrium - because the final brightness ends up being lower, regular test patterns will say that brightness at each IRE level is where it should be when in fact it lags behind. It only catches up with target brightness at 100 IRE because brightness is being throttled more with each IRE level.
For example, at 50 IRE, the theorectical brightness should be 21.46% of white brightness, except the white brightness at 50% IRE is higher vs. 100% IRE. What is important is not the 100% IRE brightness, though. because it is throttled and has no impact on intra-picture gamma.
What is important is the 50% IRE brightness, which is higher. So while regular test patterns lead you to believe brightness is where it should be and gamma is 2.2, in fact it is lagging behind for the full brightness spectrum.
So in conclusion:
We need to recalibrate gamma on this display by using APL test patterns - they are the only ones that should ever be used on displays with adaptative brightness where brightness is a moving target.
OR
We need to deactivate the adaptative mechanism (which would have the secondary effect of improving overall brightness)
But as long at the adaptative mechanism exists, we will never be able to have perfect gamma at all APL levels. If we choose to have perfect gamma at 50% APL, we will have brightness below target for low APL levels (since the 50% APL brightness will be lower than at lower APL) and it will be ahead of target for higher APL levels (since the 50% APL brightness will be higher than at higher APL levels).
So in essence, because of the adaptative mechanism, we can never have a perfect intra-picture gamma that works equally well at all APL levels.
The standard error will be smaller at lower brightness levels because the peak brightness range will be more narrow. But in boost mode the max brighness will be 70%higher than minimum brightness, so the standard gamma error at low APL and High APL levels will be higher, so black crush will be quite big for low APL and white crush will be quite big at high APL.
In a nutshell, if we want perfect gamma, we will have to acccept lower intra-picture contrast at lower APL and equalize brightness on the maximum achievable non-thottling 100% brightness. Since the display is very linear, this should yield us perfect gamma and RGB balance for all brightness levels that the user chooses between 0 and max user-selected brightness.
On plasma displays, throttling typically only happens above a certain brightness level. and it is enough to stay within that comfort range But the fact that brightness is being modulated for different APL levels on the S4 makes a good calibration that works at all APL levels impossible...
I can't believe how imaginative Samsung is when it comes to fooling reviewers. The display has potential, I just know that calibrating this thing with undefeated adaptative brightness will not yield perfect results - unfortunately.
The mos pressing issue at the moment is the green push though and oversaturated colors, though. I am pretty sure that reducing color saturation will also impact greyscales and brightness on this display...A lot of fun coming our way

Mod Edit: Don't quote the OP
Actually it's me who pointed out this MOD is not necessary

Note :
This thread is not the kernel thread. This thread is about the Poison governor in my venom kernel-- And btw happy diwali to my good friends and users
Intro :
--->Poison is a governor made by me specifically for this device (A7000-a or aio_row)
--->Poison is based on ThunderX governor
--->Poison has maximum optimisation for this device
--->Poison has amazing performance on this device
--->Poison provides amazing battery backup (based on ThunderX)
--->Poison has many additional features
Features :
--->Made for A7000 specifically in mind
--->Most optimised governor for A7000
--->Has custom tuneables for various operations
--->Has support for dynamic frequency scaling modes
--->Has support for dynamic frequency scaling mode engine
--->Has sysfs tuneables linked to it for easier accessibility
What is a "Tuneable"/"Tunable" ?
--->A tuneable/tunable is any variable/value which controls the behaviour of certain things. What a tuneable does is coded by the maker of the tuneable.
How to change a "Tuneable"/"Tunable" ?
--->It's really easy! Install a kernel-editing app like "Kernel adiutor" from play store and you will have all options in it...
How to change a "Tuneable"/"Tunable" in poison governor?
1) Read above question. Below instructions are for "kernel adiutor".
2) Open the app.
3) Go to "CPU" section (in the sidebar menu or whatever you call that thing).
4) Choose "Poison" governor from the list of CPU governors. Ignore if already set.
5) Tap on "CPU Governor tunables".
6) You will now have a list of available tuneables of my governor.
7) Edit them to your preference.
NOTE : DO NOT TOUCH THE BELOW LISTED TUNEABLES UNLESS YOU KNOW WHAT YOU'RE DOING !
Which "Tuneables"/"Tunables" should be left untouched in poison governor (if you are new) ?
1) debug_mask
2) down_rate_us
3) max_cpu_load
4) min_cpu_load
5) ramp_down_step
6) ramp_up_step
7) sample_rate_jiffies <-- This one even I don't dare editing
8) up_rate_us
Tuneables Added by me :
--->Tuneable for controlling haptic feedback on dt2w
--->Tuneable for controlling Wifi power management modes
--->Tuneable for controlling frequency mode
--->Tuneables for fine-tuning the frequency mode behaviour
--->Tuneable for enabling/disabling dt2w input from capacitive buttons at the bottom
--->Tuneable for enabling/disabling pocket mode (accidental wakeup prevention in pocket)
--->Tuneable for controlling which area of the screen triggers dt2w (x,y co-ordinates)
--->Tuneables for many more things also. A total of 21 custom tuneables! Below they are explained.
Tuneables (only necessary ones) working + explanation :
1) MODE :
Function : This tuneable is for dynamic frequency handling.
Values + what does what :
---Mode 1 (Optimized/Default mode)---
The default mode. Best for normal users who only browse and use social apps etc... It has good screen-on performance and usually stays around 1.1Ghz CPU freq. Will move higher depending on load.
---Mode 0 (low mode) (battery-friendly)---
Makes available to the governor only the values less than "mode_low_freq" (936MHz by default) to keep power consumption low while also allowing considerable background work to occur. When screen is off, it will stay at 468Mhz to save power if no wakelock is requested.
---Mode 2 (high mode) (performance-based)---
The opposite of mode 0. This mode makes Makes available to the governor only the values above "mode_high_freq" (1287MHz by default). Recommended for gamers and heavy multitaskers.
NOTE : Slightly more battery use.
---Mode 3 (min-max mode) ("extreme" behaviour)---
Remains only on 468Mhz and 1495Mhz values, or the min and max frequencies set by user.
---Mode 4 (mid mode) ("ready" behaviour)---
Fixes the CPU frequencies to the value of tuneable "mode_mid_freq" (1170MHz by default)
2) MODE_LOW_FREQ :
Function : This sets the limit to which frequencies can go in Mode 0 (battery-friendly)
3) MODE_HIGH_FREQ :
Function : This sets the limit to which frequencies can drop in Mode 2 (performance-based)
4) MODE_MID_FREQ :
Function : This sets the fixed frequency in Mode 4 (ready behaviour)
5) SLEEP_IDEAL_FREQ :
Function : This is the frequency which will be usually used when phone is in sleep mode.
6) SLEEP_WAKEUP_FREQ :
Function : This is the frequency which will be bounced when a wakelock/wake command is requested.
7) AWAKE_IDEAL_FREQ :
Function : This is the frequency which will be usually used when the phone is active
8) VIB :
Function : If dt2w is enabled, you will feel a vibration on dt2w. This tuneable changes the extent of that vibration.
Value : The value is in milliseconds, so 1000 means phone will vibration for 1 second on dt2w.
9) DT2W_ON_BUTTONS :
Function : If dt2w is enabled, this will enable/disable dt2w on the hardware capacitive keys.
Value : The value is a bool (only 0 and 1). 0 means dt2w from buttons is disabled. 1 means opposite.
10) WIFICUSTPOWERMODE :
Function : It controls that behaviour of wifi networks.
Value : It can take three values. "2" means full speed wifi, may use more battery. "1" means more battery, on cost of speed. "0" is a value even I don't understand. Default value is "2".
11) X_LEFT :
Function : Dt2w will only trigger from the part of touchscreen on right side of this co-ordinate.
Value : Default is 0, can be set upto 720, or X_RIGHT (whichever comes first)
12) X_RIGHT :
Function : Dt2w will only trigger from the part of touchscreen on left side of this co-ordinate.
Value : Default is 720, can be set upto 0, or X_LEFT (whichever comes first)
13) Y_UP :
Function : Dt2w will only trigger from the part of touchscreen below this co-ordinate.
Value : Default is 0, can be set upto 1280, or Y_DOWN (whichever comes first)
14) Y_DOWN :
Function : Dt2w will only trigger from the part of touchscreen above this co-ordinate.
Value : Default is 1280, can be set upto 0, or Y_UP (whichever comes first)
NOTE : Using the combined co-ordinates of X_LEFT, X_RIGHT, Y_UP, Y_DOWN (which makes a square), you can define the part of touchscreen which triggers dt2w. Also note that the default values (0,720,0,1280) make the whole touchscreen, so by default whole touchscreen can react to dt2w.
15) REVERT_DT2W_AREA_BOUNDED_BY_XY :
Function : This tuneable gives its function from it's name. This tuneable reverses the area for dt2w bounded by the co-ordinates.
Values : This is a bool (only 0 and 1). On "0" value, it means off. So dt2w will work only from the area bounded by x_left,x_right,y_up,y_down. On "1" value, this tuneable will activate and dt2w will work only from the area NOT bounded by x_left,x_right,y_up,y_down (on touchscreen only). This tuneable affects only touchscreen dt2w. Note that this value doesn't affect the "dt2w_on_buttons" tuneable. Default value is 0, means dt2w will only function in the area bounded by the co-ordinates.
16) POCKET_MOD_ENABLED :
Function : This tuneable enables/disables pocket mod (accidental proximity wakeup). This should be disabled in ROMs with proximity wakeup support like RR by @Rohan Taneja and all vibe roms. This should be kept enabled on all other ROMs.
Values : This is a bool (only 0 and 1). On "0" value, proximity sensor check is disabled from kernel. ROM proximity check will still work. On "1" value, proximity check is enabled and screen won't wake up if proximity sensor is covered. This might conflict with proximity checks of ROMs... (advanced : ...but the workqueue should handle everything, thus eliminating conflicts, but using double power for same thing on every wakeup call)
17) AC_CHARGE_LEVEL :
Function : Sets the maximum limit of current level while charging with ac.
Value : Can be from 1500000 to 2500000
18) USB_CHARGE_LEVEL :
Function : Sets the maximum limit of current level while charging with usb.
Value : Can be from 900000 to 1500000 (maybe. I don't remember)

Really good explanation bro ! :good:

I'll update the thread with 4 more tuneables which are in my last build (27oct)

First post updated with 8 more tuneables!!!:highfive:
Latest high performance version of venom coming up on Nov 12th (Sunday). Yup! That's less than 20 hours!
Be patient and tomorrow, just download the venom kernel after release... Download as if it will be your last breath if you don't download it fast lol
Stay tuned!

Before I go for this year from xda, here's my last piece of contribution.
Poison CPU governor is now open source!
Means it can be added to even other kernels!
Here's the source code of my governor :

Ac_charge_level
Where do I set the charge level at?

just wanna know if i can turn off d2tw on screen and enable dt2w on the hardware capacitive keys only? plus i want to disable all the off screen swipe gestures.

Yes. And yes.
With venom, you are in power. You decide how you use your phone, and I make it possible. Try not to get lost in the options lol, I didn't even realize there are so many

I just finished editing kernel to my liking. It's absolute beauty everything is well thought out and easy to understand. Thanks for the outstanding kernel.
@tanish2k09 any way to charge fast, it seem really slow to me.

Fast charging is enabled by default in latest venom, and it's the fastest you're gonna get in any custom kernel.
It might seem slow for a variety of reasons. First, the chipset is derped, and doesn't know what battery level is actually is. Second, the battery drain causes part of charging to be super fast but other part to be super slow.
Third, the kernel flash didn't quite like itself, so an easy fix would be to reflash the same zip again.

Quite understanding, thanks for the explanation @tanish2k09, I'm gonna keep it as it is, no biggie backup this kernel provide is I'm all about.

Just downloaded hopefully this one can become the go to app for notifications that we need. Thank you.
Editne minor complaint and one suggestion off the get go
Complaint: minimum of 10 second pulse, personally I like the pulses around 3 seconds so I can see with a glance especially at work if I have a notification
Suggestion: implementation of per contact color of notifications, or at least give certain contacts a special color

Hello,
Great work !
best notification app for oneplus this one is a lifesaver to me
(in future improvement) would it be possible to have multiple notifications on the screen ? or select the number to display ?

This would be very specific as not all apps show notifications which have contacts in them like WhatsApp, Messenger, etc. Nice suggestion though. I'll think something on similar lines

Multiple notifications aren't possible because of the way Ambient Display works. It will always show the latest notification. The work on the app was actually started with this idea of multiple notifications but the Ambient Display itself doesn't support it

Oh that makes sense and no biggie was just an idea, faster pulse options would definitely be a good touch though. Also found something else that would be nice, a hex code box on the color chooser would be nice for those of us who want the color just right.

I think something like ""quite hours" would be nice. When you goes to bed and put your device next to it, is no fun to have phone which flashes screen every 10 sec

Keeping an eye on this as it is similar to pixel pulse. Glad to see we have options

Great app but if there any chance to include the clock in the pulse? I assume I can't be the only one that uses their phone as their bedside clock.

It's not off actually. When notifications are rendered, the icons are small and colors go a bit on the lighter shade. Adding an update to set color as hex directly

Maybe a video of the effect?

Themes / Apps / Mods [App]Galaxy Max Hz (Refresh Rate Mods, Screen-off Mods and More)

About this app:
Refresh Rate Control: Easily control the max refresh rate (Hz) of android devices with multiple refresh rates (e.g. note20 ultra, s20/S20+/S20Ultra, z fold 2, s21/s21+/s21Ultra, tab S7/S7+, z fold 3, z flip 3). This app can limit max refresh rate to 96hz (or any available refresh rate) on supported smartphones - you can save power with negligible difference on smoothness. Use either the in-app toggle or quick settings tile - ADB setup or Root NOT needed.
Note: 96hz on adaptive does not work on outer screen on Z Fold 3.
Force High: Option to force (fixed) a refresh rate mode (High Mode) on Samsung devices with native Adaptive motion smoothness***
Current Samsung smartphones natively supporting adaptive refresh rates:
Galaxy Note 20 Ultra
Galaxy Z Fold 2 (inner screen)
Galaxy Z Fold 3
Galaxy S21, S21+, S21 Ultra
Galaxy Z Flip 3
Refresh Rate Monitor: Observe how multiple refresh rates work on your device. Use either the in-app toggle or quick settings tile
Quick Resolution Switcher: Easily switch to any supported resolutions using the included quick setting tile***
Quick High/Adaptive on Power Saving Mode: Easily switch to high or adaptive motion smoothness mode (from Standard) even on power saving mode on supported Samsung smartphones.***
Note: Stopped working on ZFold 3 updated to OneUI4.*
Force to Lowest Hz: Force lowest refresh rate on screen-off/AOD. This overrides Samsung's strange stock behavior which sets the refresh rate to the highest on screen off (update: it is now at 60hz since oneui3.0) - to improve standby power consumption a bit - ADB setup or Root NOT needed.
Auto apply power saving mode during screen-off (after ~ 10 secs)***
Tasker plugin support: Automate GMH settings using the app's Tasker plugin support. Supported actions/variables: Max Refresh Rate, Keep Motion Smoothness on PSM, Motion Smoothness Mode, Quick-doze Mod, Change Screen Resolution. (new in v7.10). More info in FAQs below.
Premium Features:
Keep High/Adaptive motion smoothness when power saving mode is enabled whether manually or by the system/adaptive power saving***
Note: Stopped working on ZFold 3 updated to OneUI4.*
Adaptive refresh rate mod for devices supporting multiple refresh rates but do not have the stock Adaptive motion smoothness (e.g. S20 series, S20FE, TabS7/S7+) with the ability to set the brightness threshold for its activation***
Quick-doze mod: Quickly enter doze mode during screen-off that can not be interrupted by motion ***
Set minimum refresh rate for adaptive mode to 60hz or lower (if available)***
Resolution switcher filter: Filter what screen resolutions to include for the resolution switcher QS tile.
Auto SENSORS OFF (experimental non-root workaround):
Device sensors will automatically turn off while screen is off until the device is unlocked. This helps minimize battery-draining motion-triggered wakelocks while device is not in use.
7-day Premium Trial is available. Just click "Activate Premium|Trial" button and activate free trial when prompted.
Note: Ad-free license is on a per device basis.
***these marked features require a one-time ADB setup (this is not root)

Thanks.

Try to do the adb setup. Let me know if this fixes it or not. Thank you

That didn't fix it. The front screen gets stuck at 60hz whenever I choose 96hz for "refresh rate mods" whether or not "force lowest hz" is active. If I select 96hz then the front screen will only be at 96hz until I turn off the screen again. After I turn the screen back on it gets stuck at 60hz. The only time the front screen goes any higher than 60hz is when "refresh rate mods" is set to 120hz.

I have no issues. This are my settings, so don't know if I set it up differently.
Edit: Had toggle off but screen on shows 48hz after wake up but build one in Android shows 96.

I forgot to mention...the problems I'm having above are in adaptive mode.

I'll buy a premium license on my Fold 3 if you add an option to individually set the refresh rate based on if the device is opened or closed. I want 60hz when the device is closed and 120 hz when the device is opened to the larger screen (really a dropdown menu box to choose 120 or 60 for each screen would be best that way you could set any mode combo you want for when its opened or closed.)

I have the same issue on my Fold 3 that the refresh rate goes to 60 on the front screen if you set the refresh rate to 96

Also happening after screen is off？
What happens when switching from inner to outer screen, is it the same？
Thank you.

120hz on one and 60hz on the other is possible.

Now it is fine. Thanks.

If you look at the official Samsung website, the screen resolution is 2340 x 1080 (FHD+) but the GMH profile has a screen resolution of 2400x1080 (FHD+). So which one is correct. Thank You

It's not applicable since 60hz is the only min hz option for S21FE

Thanks for the app, I already bought the full version. I hope the resolution can return to 2340

Hi,

You need to be connected to internet while reloading.

after trying it turned out that version 7.14.20 the resolution can be 2340, 7.14.30 is 2400

Will this be fixed for 7.14.30 or should i downgrade?

Yes, I mistakenly changed the in-app profile to 2400 in the latest version, thinking it's the right one for S21 FE .
But I already reverted to 2340 the profile on my backend. So everyone can reload it even in v7.14.30. while connected to the internet.
I'll revert the in-app to 2340 in the next update.

No need to downgrade. Just reload profile while connected to internet so the device will get the backend copy.

Judging by the Hz counter in Developer Options, it works like a charm to set refresh rate to 10hz when the AOD is on on the S22. Thank you for your work!

Max 96Hz don't work on my S22 Exynos with last update.

Same here with Snapdragon variant, seems to just drop it down to 60 according to refresh rate overlay in Developer settings.

S22 SD variant here, I can confirm
96hz does not work when set as Min/Max (will default to 60hz)
48hz does not work when set as Min/Max (will default to 30hz)
Other than that, Great job. I can see myself getting premium.

Strange. S22 is advertized to support 48hz.
May I know the lowest refresh rate S22 normally goes down on stock (when galaxy max hz is not installed)? Thank you

S22 SD, 96Hz adaptive doesn't work. It will switch between 24Hz and 60Hz....However, setting Max Hz to HIGH 96Hz works but will keep 96Hz as fixed.

Seems that samsung disbaled 96Hz on Adaptive mod on S22. Hmmm..

v7.14.35 in-app update
-Bug fixes

I brought the premium version of galaxy hz for my s20 a while ago, could I somehow migrate the license to my s22, like deactivating s20 version and enabling it on my s22?

Coffee

96Hz works again after the latest update.
And after 3 hours it doesn't work, again.

i've bought the pro version for my s22. What I'd like to achieve is 96hz adaptive to 24hz. Not possible atm. Let'hope Tribalfs make it possible

Hello, for to get more lower frequencies ( 30-48 mhz) i have to disable the battery saver ( when i place this battery saver option the screen is placed to 60 mhz by default), can you fix this? thanks
