Increasing torch power with root

[gabed90]

Does anyone know how to increase the torch power? Like z1-z2-z3 years ago?

DELETED - misread

I havent heard of that and touch sensitivity is really good but I think you can increase it b enabling glove mode.

I haven't figured out how to increase the stock torch brightness the same way I could on the Z3c, but I found an okay workaround to override it temporarily. On the stock MM ROM I'm running, the brightness is controlled by two files: "/sys/class/leds/led:torch_0/brightness" and "/sys/class/leds/led:torch_1/brightness". You can edit these to any number (don't burn out your led....I haven't tried anything above 1000), then toggle on the torch by changing "/sys/class/leds/led:switch/brightness" to "1". The torch can then be turned off by changing "/sys/class/leds/led:switch/brightness" to "0". The stock flashlight brightness is "12", which is really dim, but "90" has been a good brightness for me so far.

I wrote a script (attached) which toggles the torch on and off with a "90" brightness. It has to be run with su (root).

#!/system/bin/sh

toggle=$(cat /sys/class/leds/led:switch/brightness)

if [ "$toggle" = "0" ];then
	echo 90 > /sys/class/leds/led:torch_0/brightness
	echo 90 > /sys/class/leds/led:torch_1/brightness
	echo 1 > /sys/class/leds/led:switch/brightness
	echo "on"
else
	echo 0 > /sys/class/leds/led:torch_0/brightness
	echo 0 > /sys/class/leds/led:torch_1/brightness
	echo 0 > /sys/class/leds/led:switch/brightness
	echo "off"
fi

Also I used Script Manager to set up a home screen widget to run this script, so I have a "bright torch" toggle on my home screen. Maybe someone could make this into an app so this solution wouldn't be quite as clunky.

Hi! Does it work? How can I install it?

 

[mains75]

I tried to do the widget, but when I start it , Permission denied appears.
I have rooted device, and I gave SM manager root permissions...

Do you have the "Su" toggle turned on for that script in SM Manager? It's in the top bar when you setup the script.

 

[mains75]

Yes I have..
After some attempts It worked... Thankyou

I wonder why if I edit the 2 files manually, system resets their value after you turn on the torch with other apps...

Thank you - your script works well!

A minor issue is that when you run the script thru the widget shortcut, it pulls open the Script Manager app. Do you know any way to avoid this? Maybe an additional line in the script that kills the current app?

Thanks again.

Good idea. Add this line to end of the script and it will close Script Manager.

killall os.tools.scriptmanager

Thanks - that works perfectly.

xz1 compact

I tried to run this script on Sony XZ1 compact, but when running ScriptManager writes "No such file or directory". What am I doing wrong? ROOT mean. The path on the system and similar files exist. I turn on the SU button at startup. Help please.

Thanks for the guide, now I successfully edited my config, and I can use godly torch app to control light intensity.

i edit name folder switch to worck for xz3 i tested for me is worck good and plzz i need mehtod before edit in rom like defaut

 

[blackhawk]

Meh... bear in mind the led current was sinked at that level for a reason.
Although it goes much higher with the camera, it's only briefly.
Running it full time like that may exceed it's heat sinking capabilities and prematurely burn it out.
Everything happens for a reason... and it probably wasn't to keep you in the dark

plz i need methode for edit firmware or system for adjust torch

script worck for me for xperia xz3 by change switch to switch_0 and i need methode for set auto by sysytem
