Question Flashlight Brightness Mod? - Sony Xperia 1 III

So apparently the 1 III suffers from the same issues as its Sony Predecessors... The Flashlight is very bright when you use it as camera flash, but when you turn on the flashlight, its artifically throttled to idk, prevent overheating?
So for the older Xperias there were ways to modify flashlight configs and librarys. However, I havent found a way to edit the current parameter for the flashlight on the 1 III. For the 5 II the GodlyTorch App seemed to work, according to a report in https://forum.xda-developers.com/t/...ness-fix-torch-light-not-photo-flash.4203293/, but that doesnt want to work on my 1 III (I have Root)
Now the question: Can someone find the parameters to increase Flashlight LED Current via Magisk Module, XPosed/LSPosed Module or manual edit? I'd be even willing to donate to a kind developer who builds a usable flashlight mod for the 1 III.
Thanks in advance.

When flashlight is on and your device is rooted, you can change the value of
Code:
/sys/class/leds/led:torch_0/brightness
/sys/class/leds/led:torch_3/brightness
(There are two flash LEDs)
The max value you can set is given by the max_brightness file in the same directory.
I didn't find a way (yet) to apply this by default, you have to have the flashlight running in order to change its brightness that way.
However, I do warn you that I am not responsible in any way if using your LED at full power causes damage to your device.

Thanks for this info, working fine for me!
I played a bit around with this and tested the brightness values with 150; working fine in terms of short term heat development.
Edit 2: After a few days I start to notice a very slight discoloration of the diffusor with a value of 150. Its not affecting anything and barely visible, but I'd recommend to go lower than 150, because I suspect the LED may get too warm for the diffusor. I changed the guide to use 30 for now (which equals double the brightness compared to stock), please test your values for yourself, its probably better to not exaggerate it.
Make sure you type in the values right! Too high values and the LED Diffusor may melt, or the LED might die. Do this modification at your own risk, no matter at which brightness you target! I am not responsible for side effects resulting from the mod.
With Terminal Shortcut Pro and assigned Root Priviliges I made myself a Home Screen Icon that will boost the values for me in the current "Torch session" once the LED is turned on before. Other terminal emulator apps will work too.
In the Shortcut I set Run with Root and used the following command
Code:
echo 30 >> /sys/class/leds/led:torch_0/brightness && echo 30 >> /sys/class/leds/led:torch_3/brightness
Basically just a command that writes the 30 brightness value to the 2 files.
If someone can find a terminal command that turns on the flash in the first place, we could combine the commands to potentially make a simple but working replacement quick settings for the torch.
Edit: Thanks to the XDA Community and a Tool I was able to recreate the Torch experience with a Quick setting
You need https://play.google.com/store/apps/details?id=com.quinny898.app.customquicksettings
You have to buy the premium in app purchase for 1,29€ to unlock Root Command Running. Then you configure your quick setting (choose the Advanced -> Root Command under Preset) and paste the following script (credits to https://forum.xda-developers.com/t/increasing-torch-power-with-root.3637773/post-73098701, modified by me for 1 III)
Code:
#!/system/bin/sh
toggle=$(cat /sys/class/leds/led:switch_0/brightness)
if [ "$toggle" = "0" ];then
echo 30 > /sys/class/leds/led:torch_0/brightness
echo 30 > /sys/class/leds/led:torch_3/brightness
echo 1 > /sys/class/leds/led:switch_0/brightness
echo "on"
else
echo 0 > /sys/class/leds/led:torch_0/brightness
echo 0 > /sys/class/leds/led:torch_3/brightness
echo 0 > /sys/class/leds/led:switch_0/brightness
echo "off"
fi
Once again, make sure you type in the values right! Too high values and the LED Diffusor may melt, or the LED might die. Do this modification at your own risk, no matter at which brightness you target! I am not responsible side effects resulting from the mod.
Then you get rename the toggle, give it a nice Torch Icon and set the color to grey. It will function like the normal quick setting: Tap once, it turns on, Tap again, turns off. Even works locked.
Good luck and best regards.

If you want to use the Google Assistant Button as a torch toggle and also have Quick Settings Toggle (sadly its always toggled on) i found an app that can do both.
You need:
LSposed/Xposed
Root Shell access (adb shell)
Xposed Edge pro
Busybox for Android NDK (Magisk Module)
XperiaGAButtonRemap (Magisk Module)
Open a cmd or powershell
execute adb shell
execute su
accept root permissions on your phone
execute vi /bin/torch
press the key i
paste the script:

echo 150 > /sys/class/leds/led:torch_3/brightness
echo 1 > /sys/class/leds/led:switch_0/brightness
echo "on"
else
echo 0 > /sys/class/leds/led:torch_0/brightness
echo 0 > /sys/class/leds/led:torch_3/brightness
echo 0 > /sys/class/leds/led:switch_0/brightness
echo "off"
fi

Click to collapse
press ESC
type :wq and press ENTER
execute chmod +x /bin/torch
Now you can execute /bin/torch as root and it will toggle the torch with higher brightness values.
In Xposed Edge enable "Keys" toggle and open it. Tap on "+ Add" at the bottom, press the Google Assistant Button, it should be recognized as "KEYCODE_PROG_BLUE", then set the action of either click/double click/long press (whatever you prefer as the torch toggle) to execute a Shell command, enter /bin/torch in the input field and enable the "Root access" toggle.
If you want, you can also set other custom things to the Google Assistant button for the other 2 states.
For the quicksettings menu tap on "Quick settings tiles" in the main menu of Xposed Edge and enable the first tile and open the settings for that tile. Set the action, again, to a shell command, input /bin/torch and enable Root Access. You can set the label to "Torch" and choose the Torch icon found in "Built-in icons". As i already said, the toggle will always be turned on for some reason. It just executes a shell command after all.
Good luck

Amazing, thank you everyone.
However, please let me insist that this may damage your phone if you put values too high... trust me. I accidentally put a brightness of 350 instead of 150 while trying the script in a terminal, and a few seconds were enough for the plastic underneath the glass to melt... Thankfully, it is still transparent so I can still use my flashlight, but no doubt it could have done a lot more damage if I let it run for longer. So please, use this with a lot of care (and double check what you write).
That's why in lots of countries, rooting voids your (hardware) warranty, you can do physical damage to your device so again, please be careful. Thankfully, this plastic bit and even the LED underneath are easily replaceable (the plastic bit is separated from the rear glass and the LED is on a separate ribbon cable). However, there don't seem to be a lot of OEM replacement parts for this phone yet.

Seems like a lot of work for little return and added threat of damage to an expensive phone. I agree that the brightness is dimmer than other phones I have had...but I did a test in a completely dark room and it actually is bright enough to find "whatever" you may be looking for. So I can live with it. Maybe Sony will do something to improve it a little?

Sony could definitely improve it. But it seems like they had a history for compareably dim Flashlights.
I edited my explanation post to adapt lower brightness, because 150 as value starts to slightly discolor my diffusor, so I suspect we should run it lower.

太棒了，谢谢大家。
但是，请让我坚持，如果您将值设置为高，这可能会损坏您的。......我相信在终端中尝试手机时，我不小心将恢复设置为 350 而不是 150 ，几秒钟就可以让玻璃下面的恢复正常……幸好还是可以的，所以我可以使用我的手电筒，但有疑问，如果我能运行更长时间，它会请小心使用它（并仔细检查你写的内容）。
这就是为什么在国家/地区，root 导致您的许多（硬件）故障，您可能会再次对您的设备造成物理损坏，请小心。值得庆幸的是，塑料钻头甚至下面的 LED 都可以轻松更换（塑料钻头与后玻璃分离，LED 还位于单独的带状电缆上）。

You can't say I didn't warn you!

Indeed flashlight in mark 3 and older xperias is very bad.
I compared it to an iPhone and it's like day and night. Many aspects xperia brand is suffering like front camera, flashlight, no 21:9 pics, missing 4k 60fps recording in main app with stabilization, poor screen brightness, insufficient battery capacity, no any cooling system (especially at this price there should be vapor chamber or any other advanced cooling and not throttling cpu as a solution...), Not to mention regular software apps like Album, email and others :/

I got it fixed through sony aftermarket and has ip68,fixed the screen for me by the way

On android 12 after rebooting the function stops working.

---

So I got to the area of the phone you guys specified, but as of today, the default values are WAY different that what yall found. Let me take a few screen shots

---

Here is the systems default peramitors. Any idea why they are so different?
Edit- Okay, so extra piece to the puzzle. When torch is off, the brightness file is 0, but when it is on the file is set to 15.
editing the file while the torch is on does nothing.
Edit 2 - Just wanted to note that for those who just want a demonstration of the changes possible, the fallowing app will do just that
Release v1.4.6 · BRoy98/GodlyTorch

this app needs root. Run it as a HTC 10 and it works just fine. However, I would like to recommend NOT going over the half way point. its VERY bright and will probably kill your LED if you do. You have manual control over the brightness. You can add it as a shortcut in the drop down menu of your phone. simply use the standard torch button, and then click the godly torch button to activate whatever preset you gave it.
Edit 3 - setting the brightness in Godly Torch to 50% Intensity sets the brightness to 135. Given that we know damage starts to happen at 150, I set the brightness in Godly to 15% (under the "toggle Intensity" shown in the screen shot), which brings the brightness to a value of 45. Its easily double as bright. I would not recommend going past this point.

---

I would say by using godly torch as a HTC 10 worked...mind you I double checked the brightness by just hitting the quick toggle and then messing with godly torch. The lower setting is matching just turning on the quick toggle the higher setting is what I'm comfortable with, but idk how long I'm comfortable running it at that brightness.

For those on stock who use the assistant button :
If it stops working after reboot, copy the binary file to somewhere safe on your sd card, then using XPosed edge just add a long press gesture to your assistant button that recopys the file from your sd card, then sets the permissions again (make sure to check run as root)
cp /sdcard/torch /bin/ | chmod +x /bin/torch
