[APP][ROOT][4.0+] Adjustable Torch

MohammadAG · Aug 8, 2013

Adjustable Torch is an application that allows you to use the torch at different brightness levels.

Screenshots:

Compatibility:
Tested on the Galaxy S4 (GT-I9500), will work on all devices with either of these files /sys/class/camera/flash/rear_flash or /sys/class/camera/rear/rear_flash
Installing and running the app will tell you if the app is compatible.

Reported working on:

Samsung Galaxy S4 (GT-I9500, GT-I9505, SGH-l337, SCH-I545)
Samsung Galaxy Note 2 (GT-N7100, SGH-I317)
Samsung Galaxy SIII (GT-I9300)

Source:
The app is open source, and licensed under GPLv3: https://github.com/MohammadAG/android-AdjustableTorch

WARNING:
Using the flash at maximum brightness may cause damage to the flash. The developer of this application is not responsible for any damage caused to your device due to prolonged usage of the flash at a high brightness.

Permissions:
I request and use the following permissions:

Internet: used for ads, ads can be disabled in Action Menu.
Superuser: obviously needed to write to sysfs.
Receive boot complete: needed to reset app settings at startup. A reboot would turn off the flashlight so this is needed.

If your privacy app is picking up location as a used permission, please report a bug against it, again, I DO NOT use location.

Download:
Get it from the Play Store!
If you can't access the Play Store, here's an exact copy of the APK on the store, please use the store if possible, thanks! http://mohammadag.xceleo.org/public/Android/AdjustableTorch_1.6.apk

Great app! Very bright if needed and not so bright when less light is required.

Half works on my I9300 but the brightness doesn't coincide with the slider.

For example if I tap it to "full" it's off again and no matter where I tap along the line it goes brighter or dimmer as it pleases

Otherwise, brilliant app! Been liking for exactly this for months!!

Looking forward to updated versions

Tried on my galaxy Ace II I8160. The led brightness goes from 0 to five and then continues from 1 to 5 while moving the slider from left to right and right to left

I guess I'll have to add a settings option to set the maximum brightness, for the S4 it was 15, anything more than that and it the brightness stays the same.

Permissions question

Thanks for the app.
Can you please explain the need for some of the permissions?

Using Xprivacy, I can see that it requires Location, Network, Phone, Storage and other permissions I would normally not associate with an app like this.

Thank you.

I explain the permissions used in the Play Store description.
I don't request permissions for Location or Storage, it might be AdMob or writing to my own app's preferences.
If you still don't trust that, it's open source

Can you add a small widget with vibrations when we put on/off the light ?

I'll see about it, haven't worked with widgets before so it'll take time.

One more thing, I use XPrivacy too, and it didn't pick the app up as using location, not sure where you got that from.
In any case, added permissions to OP.

Here's your app next to Google Authenticator.
Hope this helps.

Which XPrivacy version is this? As you can see, the green key icon is missing, which means I don't have permissions for location.

Can you tap the arrow on location? I want to see the methods used.

Edit: here's a screenshot of XPrivacy on my device.

Where do I get this app from???

Be careful!
When using this app AND in addition turning the light on with another app, the maximus light will be increased! It seems to me that the values of light will be summed up! So when using only 20 percent of full light, it will be increased up to 120 percent when turning the light on with another app. That is very dangerous!

Another problem for me: The flashlight seems not to be off @0 percent. In an absolute dark room I can see a little glow. Seems to me that the flashlight is not fully turned off at 0 percent.

I hope, someone can confirm my experience and that this little bugs can be solved

This developer needs a double thanks.

EDIT:That file doesn't exist on my phone

Yeah isn't that why you have Xprivacy installed? To associated with "apps like these"?
