Is there a Brightness control application for Samsung i780

The Brightness control of the Samsung i780 isn't very accessible.
Whenever at the open, adjsting the brightness when you hardly see anything on the screen is close to impossible.
The brightness control of HTC home doesn't work for me on this device,
And I couldn't find any application that would enable changing the LCD brightness.
Not at all or at least as easily as the button in the Samsung Today plugin that came with th UK ROM MSHC3.
I can't use this plugin now (different ROM, un configurable plugin...)
So I'm asking,
Do any of you experts have a suggestion/solution?
Thanks.

Any clues anyone?

yes there is, go into
settings
system
backlight
scroll the tabs across at the bottom
there should be an option for brightness
even the top one is not hugely bright though, better than nothing.
Hope this helps.

I wonder if some talented chap could make a proggie that would adjust the backlight automatically using the small VGA camera as a light sensor, that would be pretty neat IMO

That's the exact point I was trying to make here:

Why should there be an application like that for Palm OS and not for WM?
But for now I would settle for a today plugin or small application.
that could be assigned to a hotkey that would round robin through the different brightness levels.
Thus making the access to the brightness control easier to access...

Was an app ever developed to solve this problem?

there's this guy over at ppcsg, moneytoo that's made such an app.
i especially like the brightness toggling, very convenient.

Here's the whole post with "screenshot"
I made this simple tool for easier switching backlight on i780. Install SamsungBacklight.cab (if you have non-English non-English environment you may have to try SamsungBacklight.exe and create shortcuts manually)
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The installer will create 4 links in Programs\Backlight (MAX/MID/MIN/TOGLE) so you can easy assign button to any of this action.
Run "SamsungBacklight.exe 1" to "SamsungBacklight.exe 5" to set prefered backlight level. "SamsungBacklight.exe T" will switch backlight between level 1 and 5.

its works
THX!

Thank you
Thank you "thescum" for pointing me to the right direction,
Thank you "moneytoo" for creating this useful utility
I now can get rid of the files I created for setting the brightness level through registry import
Now, how about using the vga camera as an ambient light sensor...
thanks again

Thx moneytoo
I was looking for exactly the same thingie
Btw. Do you think you can modify your programme to switch through all levels of backlight increasingly with each run? (each run would lit up the screen +1 level) This could be a great app to bind to a hardware key

Brightness control from AE Button Plus also works fine. You can map the pop-up controller on the long or double press of the button you choose. Settings of brightness control for i780 is as follows:
- min level = 4
- max level = 9
- step = 1

CM Automatic Backlight Settings (explained)

Got fed up with the lack information so I did some googling and made a post on my blog.
My Bloggy
If anyone has any good links or info to add that would be greatly appreciated! I'm still personally trying to find my own settings.
The Automatic Backlight settings (CyanogenMod settings-->Display-->Automatic Backlight) allow you to customize how your phone reacts to changes in ambient light measured by the phone. You can control how many light level ranges you want to monitor, and how bright you want the screen, keys, and keyboard buttons to be at each range. Of course you have to enable Automatic Backlight in the normal Android settings first (Display-->Brightness).
In googling around on this I've found a number of different approaches and preferences, and it really is something that is very subjective - enough light for one person at a particular ambient light level is too much for another, and vice versa.

The first three settings: Windows length, Reset threshold and Sample interval control the filter conditions. The Windows length is the amount of time for the average figure, while the Sample interval is how long the system waits to take a sample. Personally, I go with larger figures to reduce system load and save battery life.
There are two primary benefits offered by filtering:
1. It can allow you to set up smoother brightness transitions (assuming you also increase the number of custom levels)
2. It can decrease the likelihood of screen flicker in mixed lighting. ( You may find yourself in mixed lighting conditions that straddle two raw brightness levels. Without filtering, these raw levels may cause your screen to repeatedly shift back and forth between two brightness settings. I've found this can easily happen with artificial lighting as it is more directional than natural lighting. Sitting in your office, for example, you may find that simply shifting the angle at which you hold the phone changes the brightness reading.)
Notice that without filtering, the screen brightness jumps back and forth between 70 and 55, which can be very distracting. The filter, on the other hand, maintains a single value for the screen brightness, even under these fluctuating lighting conditions.
Window Length: Filtered value is the average sensor value during this period. Larger values = slow response.
Reset Threshold: There may be times in which you want the screen to respond quickly to changes rather than slowly ramping. Moving from a dark building out in to broad daylight, for example, you don't want to watch your screen slowly brighten over the course of 30 seconds: those are 30 seconds in which your phone may be unreadable. This is where the reset threshold comes in handy. If a raw reading differs from your current average by this amount, the filtered value is immediately reset to the raw value. Finding the right value for your reset threshold allows you the best of both worlds: a screen that gradually changes based on subtle light changes, but responds rapidly to extreme changes.
Sample Interval: Low value can improve accuracy but uses some more CPU.
Allow Light to Decrease: This is a very simple option. If this is checked, your screen brightness will increase and decrease according to your custom levels. If it is unchecked, your screen will brighten as the light sensor reads higher values, but will never darken, even if the sensor detects that you have moved to a very dark area. I'm not quire sure why anyone would want to uncheck this, but maybe I'm missing something.
Decrease Hysteresis: Reduces flicker when decreasing brightness
In conclusion, if you want a screen that responds very rapidly to changes in ambient lighting, possibly at the risk of flickering, decrease your filter window (or disable the filter completely) and increase your sample interval. If you want a screen that never flickers, possibly at the risk of slow responsiveness, increase your window.
Filter A: 10 second window, 2 second interval
Filter B: 20 second window, 2 second interval
Filter C: 30 second window, 2 second interval
Filter D: Same as Filter C, but includes a reset threshold of 2000
*Note how the inclusion of a reset threshold on Filter D allows for immediate responsiveness under extreme light changes while still preserving the gradual shifts at smaller changes.
As for the light sensor levels, you'll have to play with them yourself. Go to a dark area... and adjust the screen level until it's at a brightness that's comfortable for you. Then gradually increase it up to whatever is fine for outside brightness. Near the bottom you can select more levels as well.
As previously said, I mainly want to collaborate and find the best settings for our phone. Any information to add would be great. Thanks.

Thank you so much for the detailed overview. Very well done. Agreed...should be stickied.

How about you post your settings?

Excellent post. Needs to be a sticky.

And for those that are curious these ROMs (likely others) have the same implementation:

wow first time i read this 3ad..very usefull.i always have some doubt about how it works the automatic backlight settings..honestly i have always the phone to max brightness,but now i want to know better how it works this features.thanks for the wonderfull 3ad.

Screen dp

So let's talk about the biggest turn off on this phone , not the lack of NFC but the screen resolution , it's not the best and you can learn to adapt to it but here and there the scaling is just bad. Especially for others like my self coming from old flagships with a higher resolution (had an S8 and 720p is quite the downgrade from 1440p).
fortunately enough in developer options there is the option to change how the phone scale by changing the smallest width , mine is set at 480 dp and I like the phone way more than the day I got it ,
share your experience regarding the best settings for the screen scaling !

sounds good, how to do it?

Ya it was looking huge when i reverted back to 360, so maybe it happened after seeing it at 400+

390 is great.

You can use settings -> display -> GUI size (or interface size, not sure about English term). Values used by system are 320, 360 and 423dp.

any number above 423 starts cutting the battery and the clock
and the commands didn't work here

Thanks for this! Screen looks much sharper because of this! Could be placebo lol

480 works fine, my bigger turn off is the pixels you can view on the screen, you can note it when you see brighter shades on screen. add to that I'm using a matte screen protector ...and I feel this screen guard only enhances the pixel problem.

Question Poco F3 dynamic refresh rate

Hi all, unfortunately also Poco F3 has the dynamic refresh rate as in others Mi 11 family devices. In games and video apps the refresh is cut at 60Hz even if 120Hz are set. Same happens also in Poco X3, is there any way to disable this feature and fix the refresh to 120Hz?

By clearing the data of Battery And Performance in the apps section would do the job.

Not true. I already tried to disable any optimization of battery and any optimization of performance and with videogames and video apps the refresh rate is sistematically fixed to 60Hz

In YT scroling is at 120hz.I dont know about video playback and dont care couse nothing is on 120hz recorded.Video tools can add black frames but I dont like ghosting.I dont play games so dont know about that.60fps gaming is ok for me.120hz on a phone I need only for scroling because is so much smoother and nicer as it always should've been.Now 60hz looks like ****.

Hi, you can set manually through adb a frequency of 90 Hz if you want to save battery.
adb shell settings put system user_refresh_rate 90
set back to 120 with :
adb shell settings put system user_refresh_rate 120
To show the current settings
adb shell settings get system user_refresh_rate

The trick working but the refresh rate are always dynamic, so when you touch the screen the refresh go to 120 but when you dont touch the screen go to 60.... So impossible to force constant 120hz refresh rate... If anyone know how please reply...

The manual way of setting the refresh rate doesn't work in adb nor in Tasker on xiaomi.eu 12.5.5 (as well as on the older versions).
The command
Code:
adb shell settings put system user_refresh_rate 120
passes well and
Code:
adb shell settings get system user_refresh_rate
shows the changed value. But in fact nothing happened. The refresh rate is still on its previous setting. Checked in the display settings and by displaying the frequency in dev. options too. Any idea why?

Go back to 60 fps and to 120fps in display , open su and type:
adb shell settings put system user_refresh_rate 0
Setting this to 120fps does nothing. Setting this to 0 also does nothing in the long run but hey at least if you're desperate by doing this it stops refresh rate switching in its entirety for a while.
Locking screen / Rebooting / Using certain blackilsted apps or just after a prolonged use drops the refresh rate to 60 and locks it there.... So basically you have to go back to display all over again and go from 60 to 120 and apply the settings put command all over again.
This is the best option by far , I haven't found anything better than this online and it's a ****ing shame. I'm done with this , if you guys wanna try this be my guest but I really suggest aosp

Adb shell settings put system min_refresh_rate 120 will keep it at 120 all the time

I don't know about everyone else, but
I am using a custom kernel and using lineage A11, the shell commands don't work for me despite changing the setting and then checking the setting with the other shell command to se if it sets it to the other value.
But with the view refresh rate option in the dev options switched on, it always shows 60Hz. Although that is not a problem for me, but I do like having higher refresh rate for a more snappy experience.

HOW TO CHANGE THE SCREEN REFRESH RATE OF THE POCO F3 TO 90HZ
If we want to increase the battery life a little more, we can lower the refresh rate of the screen from 120Hz to 90Hz, thus we will achieve extra savings without having to put the screen at 60Hz. To achieve this, we download the SetEdit app...
forum.xda-developers.com

I use this command to make 120hz works in games (root needed) :
"su
pm disable com.miui.powerkeeper/com.miui.powerkeeper.statemachine.PowerStateMachineService"

Can you please help me more about this
I don't understand.

Use termux and copy paste the command above.

Where can I fine this dynamic refresh rate or adaptive option I have only two lowest and highest?

Adaptive means when u pick 60hz it will drop to 30hz when idle and max it goes to 60hz...try turn on the show refresh rate from developer option you'll see what I mean..

I'm having opposite issue, my f3 is 120hz always expect in apps that are forced 60 by devs, adaptive refresh only kicks in when phone is above 80% brightness which is hardly ever for me. Anyway to lower that 80% to something like 40-50%?

Question Poco F3 yellowish screen

The whites looks yellowish, like warmer tone. reading mode is off. I got phone this yesterday.
MIUI Global 12.5.6
My last phone was Redmi K30, and this is my first amoled sceen phone.

Was it like that out of the box?
If so it may be a firmware or hardware issue.
If not, 3rd party app like a book reader.

Is "Adaptive Colors" off in Color Scheme Settings?
If yes.. maybe refund/replace your phone, if it's a hardware problem...

Can you take a picture of the device showing the yellow tint? It definitely doesn't sound normal, but could be a software issue

the picture can't show the issue, but it is like you set the color temperature to warm or turning on night light/reading mode.

it is off. temperature is at default, and setting it to cool didn't fix it either. I guess I'll ask for a replacement.

If you are talking about white looking yellowish; here's what to do:
1- Go to settings > display > colour scheme
2 - Choose advanced settings
3 - Choose enhanced
4- Go to R (red) set it to about 75% and G (green) to 75% as well - Leave blue at a 100%
5- Reduce both value and contrast by about 5-10% ( just a lite slide )
6- Set Gamma to 0% ( slide it all the way to the left)
7- Save changed and report back the difference.

It's 6am, and screen is slowly reducing the yellow tint. look like this have scheduled reading mode, even though I have it disabled.

Turns out the night mode configuration was from my previous device and restored by google to my new poco f3.
I used SystemUI Tuner to disable the hidden night mode settings.

I had this problem too, what @azeunkn0wn suggested worked for me (when the screen turned yellow at night)
Without root:
1. Enable ADB like this in the developer option

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
2. Reboot the phone to apply the changes
3. Disable night display option with the commands:
- adb shell settings put secure night_display_activated 0
- adb shell settings put secure night_display_auto_mode 0
4. Reboot the phone to apply the changes
And it should be good
Note: if it doesn't work, check also:
Settings - Accessibility - Vision - Color correction - Off
