I've created a little app that lets you set the touch key brightness, but most significantly, restores your settings on boot.
It's 99p and you can find it in the Market.
This thread is to give some background for those who like to hack around... the backlight value is read / written at '/sys/devices/platform/star_touch_led/wled'. The normal values made available are 00-20, you can program higher but it's probably not a good idea!
The default level can also be changed in the kernel.
Cheers!

Nice job there Paul.
This should be a step on the way to have a solution to make buttons as notification lights i guess?

Interesting...
Hmmm almost interesting enough to start developing for andoid myself... but I'm currently too busy with other things....

I just tried to edit the value directly in the file using root explorer. When I saved and exited, the lights turned off. I tried other values, but it seems like the value only changes ones and that is to the value 0ua. Any edit after that doesn't change anything.

I had the same problem as you.
It is because you have to detete all of the text(wled: 2000uA) and write "6uA" (00-20aU ; 20uA is default)
then android will translate:
1uA = 100uA
2uA = 200uA
3uA = 300uA
n...uA = n...00uA
I'm recommending 6uA with a 30% screen brightness

I had buy your apps! it 's fix the Touch key to light problem.
If it 's can auto set on boot, will better.

This works for me also:
Code:
while true; do
echo 0 > /sys/devices/platform/star_touch_led/wled
sleep 1
echo 20 > /sys/devices/platform/star_touch_led/wled
sleep 1
done

Hmm, maybe you can use similar code to apps like SMS popup, to only light touch keys on notifications! Please try it...when the G2x for tmobile (rebranding with stock android) comes out, i'd DEFINITELY pay $5 for it.

How do you save it? File restores it self on reboot.

You can add a startup script that sets the value as you specified it
Having the button backlight "follow" the screen backlight seems like a trivial tweak tho...

This application will allow you to adjust your displays sharpness value on the fly. Default is set at 4 but has an adjustment value of 0 to 99. Choose your amount of sharpness with this app.
Vsharp is built on Tasker for the device and on the device. Tasker is not needed to run this application. This app is currently in BETA. More features and adjustments will be added in the future. If you have an issue let me know.
CURRENT ISSUES.
Don't open the app after a reboot till it notifies you it's value is restored after a reboot. Again this is BETA and is work being done on getting it resolved.
REQUIREMENTS!
Must be rooted.
Must have busybox.
Must have SeLinux set to permissive.

No. You don't need Tasker to use Vsharp. Vsharp is a stand alone application built on tasker using the Tasker app factory.
I just posted the source in the second post to show the work if someone wanted to look at it or modify to their liking

Actually my biggest complaint about the display isn't actually the stock sharpness setting of 4, but the gamma. The gamma on my V10 is off a considerable amount and I'm losing detail in dark scenes. It's definitely not around the more standard gamma value of 2.2
I hoping to tune that up in the future also with this app.

Anyone has this confirmed to be working? ^.^

It's just like setting the sharpness on your tv. It should not have any effect on taking a picture. If you see some grain effect in a pic its completely unrelated to this mod. What your experiencing is noise in a dark scene which is typical of a small, high pixel count camera sensor.
When taking a picture, try to use the lowest ISO setting possible. In a dark scene the ISO will need to be greater for a properly exposed pic. This is when you will experience the most noise.

I personally set it to 0 as there really isn't any need for sharpening. It just introduces noise in the display.

SWEET! Thanks for this! I was really bummed that the screen on the amazing V10 was not as sharp as my G3. Now its just as sharp. (doesn't seem to affect the second screen, but don't care)
I set it to value 30...anything more and it doesn't seem to do anything. Also, setting to max, 99, upon reboot is goes back to 0.
EDIT: So.....maybe an issue. The sharpening effect dies when i launch some apps, like Gallery. I then go back into the VSharp app and its reads the value and its back to 4..like it was overridden by the system.
Edit: Removed Gallery, Switched to Google Photos app. Doesn't instant kill sharp effect when that app is used.

Sharpness not sticking after screen off.
I definitely am noticing that any sharpness value is not sticking/being re-applied when the screen shuts off/locked or goes to sleep.
I go back into the app, and it reads the current value and it says what i set it to (30), but when i toggle it up or down, I can instantly see the example bars sharpen up, which proves it was off then was re-applied when I toggled the value.
I tried setting the app to ignore battery optimizations in system settings, thinking maybe the OS is killing the app in the background, but that has no effect. I also tried disabling the lock screen entirely, no change.
Any ideas? I do have other things like Xposed, App settings (530 dpi set on certain apps), Gravity Box, and G4 TweakBox installed....but none of them have any display mods enabled.
Any way to make a widget or something i can one-press to toggle the value and re-apply....vs having to use the app every time I want the screen sharp after it goes off.
Edit: Is this app supposed to may a dozen and more "Subsystem/img_tune/" directories in /sys/class/panel/...all inside of each other.
Is there a way to just change the sharpness file and lock it to read only o that it can be overridden...I have tried setting permissions using root explorer to read only...but it still get overwritten at reboot..and eventually by system.

Do i need to set selinux every time i reboot and app runs?

[GUIDE] Changing min width/DPI of MIUI 9 without rooting

Hi all, this may have its own dedicated thread but I was not able to find it during my time with my Mi 6 and Mix 2.
When I moved over to MIUI I was shocked that they removed Min Width in Developer Options, because opening apps such as Telegram gave it such a horrid text size I could not adjust.
This will require you to have 5 minutes of your lunch break, a PC, and also depending on where you are accessing your Mi device, a VPN.
ATTENTION: To those who have used this command before on other devices, the device WILL RETAIN the density after a reboot. Don't worry about doing this every reboot, because you DO NOT HAVE TO.
NOTE: This will NOT cause any reboots of any kind, and you can still use themes from MIUI or wherever. The only apps I have noticed have a weird design will be the Themes app, where the app will look off tilted. Other than that, Xiaomi should have just left this in instead of neglecting their own app's density adaptation.

I assume the vpn is for turning on ADB debugging? Does the global ROM require this as well? I'm 99% that I've used it without a vpn (though, my device is unlocked). I can't confirm now though as I'm no longer on MIUI.

I've tried the adb shell method a few times before on MIUI 9 on my Mi4 (from 480 to 400), but it wrecks the notification shade, especially on the quick tiles (it enlarge by themselves) and some notification row icons (somehow the icons ended up having small black-ish frame overlaid on the top-left). Possibly only on MM MIUI 9, since that's all Mi4 gets at best.
Is it because of how MIUI theming heavily uses bitmaps (with flawed asset scaling on their own default theme) rather than vector drawables for their glyphs?

Great work around buddy, but in the end you'll have to change the rows and columns size too as those look horrid then.
Though I used EasyDPI and Xposed to rearrange these BASIC settings, one can always use the Default Theme Layouts.

Hmm that's weird, I never had issues with my notification shade.
That is a possibility if they don't use vector drawables, but I believe it's just like how Samsung once upon a time made all their apps at a fixed DPI so scaling just looks really bad.
I've been using default theme and another theme called Flam[DD] and changing DPI works flawlessly.

The following may be much easier. You don't need adb, unlock or root.

Question Adaptive refresh rate not working.

There is a FPS counter option in the developer option. After turning it on. The refresh rate doesn't change even in AOD it stays at 120hz. I think this is the problem why our battery is poor. I try factory resetting but still the same. I think the last software update broke it.

Try clearing the system cache, a hard reboot, safe mode to rule out 3rd party apks (safe mode may disable adaptive refresh)
Try temporarily turning off Developer options.
Double check all settings, Samsung loves to hid them.
If you have Samsung Device Care clear it's data.

Have the same problem sometimes... The adaptive refreshrate needs some fixes... It also stays on 120 or goes down to 60 when looking pictures... It should go as low as 10hz then...

Having exactly the same issue here, stuck on 120 even with AOD. Exynos

Are you on low brightness ? Is adaptive brightness turned on?

My exynos s21 Ultra does go down to 48hz but never reaches 10hz. Also I'm also spotting when in lowish light, when reading the drop from 120 to 60/48 causes the screen colour to slightly change

That's interesting! I was on the lowest brightness and it says at 120 all the time, if I move the brightness a little higher, the refresh is 60 or 120, more importantly AOD is now 60.
When move back to lowest brightness, stuck again at 120, for AOD as well. Wonder if that has been killing my battery. I thought the refresh should go down to 10?

Not sure if this may answer at least some aspects of the queries in this thread:
Investigating The Galaxy S21 Ultra New OLED Emitter: Huge Efficiency Improvements
www.anandtech.com
"If you’re using your phone in dark or even dim conditions, the variable refresh rate doesn’t work at all, and the 120Hz mode comes at a huge 300mW cost in baseline power..."
"...I wish Samsung instead of disabling the VRR/LFD under dim conditions would simply switch to 60Hz mode as that would be a much more power efficient alternative. Of course, the best solution would be simply to get rid of this ambient brightness limitation and allow 120Hz and VRR in all conditions – it’s still not exactly clear at to the technical reason why Samsung is employing this limitation in the first place..."

Question Changing refresh rate to 90hz

I've read about a guide to set the refresh rate to 90hz for the poco x3 nfc and the poco x3 pro, through an app called setedit. Did someone tried to change the refresh rate for the redmi with this trick?

Which miui version are you using? You noticed differences (possibly gains) in battery consumption?

Thanks I managed to get this working too on miui 12.5.1
For anyone that's interested download "setedit", navigate to system tables tab, scroll to "user_refresh_rate" and change value to 60, 90, or 120.
Don't set values outside those or it may crash the phone.

Because the panel doesn't support 90 hz as simple as that. This is the reason why ROM devs can't add 90 hz for this device.
Enjoy either 60 or 120 hz. All trials and efforts for 90 hz are waste. That's it.
