Can you dim camera LED

I searched and found no info on dimming the camera's LED. I want to be able to use as a flashlight, but I don't want it so darn bright.
Still looking at different apps on the Play Store, but I think it would have to be some kind of hack for rooted phones, which I haven't done yet.
Any one have any ideas?

I don't think it's possible. When you use it as a flashlight android apps have a setting called "torch" and that's it. There is no modification for adjusting brightness. Also, I looked in the /sys/class/leds/ directory for the camera led to be able to enter your own value for the brightness file, but nothing exists in there for the camera light. I personally like the bright led for a flashlight. If I don't want something super bright, I use a screen flashlight that just displays a white screen and boosts brightness to Max. I personally use a red screen though.

The tricky aspect of what you are talking about doing here is that the Linux kernel is your entire power management for the device. There might be a a root flashlight somewhere in the market that could accomplish this for you, otherwise it would take some adjusting at the kernel level... which again is your power control for hardware

Thank you guys for the help and info. It's not the end of the world if I can't do this, but now I know what to keep my eye out for.
The kernel is the key to over clock and under volt, so I understand that the kernel would have to support that.

How to tweak light brightness down even further even lower on the S3?

My screen dim level is at 1 and my phone is still too bright. How could I reduce this even further so that sliding my brightness toggle in the notifications bar all the way to low will reduce the brightness even further? Is there not an option or a mod that allows you to pretty much dim your screen to complete darkness?

screen filter from playstore

I see screen filter, the only problem I have with it is its persistent notification. As far as I can see there's no way to remove it. If I could get rid of the persistent notification I would set it to boot with tasker.
Suggestions to remove from notification?

Try lux auto brightness not sure if it has persistent notification or not.

I know about lux too, but it's not what I need.
Is there a way to lower the brightness set by the kernel or is this unchangeable?

Download screen calibrator and it works like a charm, you can also remove the icon from the status bar

I looked into this too, I believe the only option is screen filter or anything like it.. which makes no sense to me.
Lower brightness = better for eyes+battery

Yeah I actually prefer the dropdown notification built into AOKP roms for brightness, but the lowest brightness is too bright. In a room with lights off, reading the amazon kindle before bed is pretty discomforting if you're trying to ease into sleep. Way too bright.
Apparently the only way to do it unless the screen filter author comes up with a way to get rid of that persistent notification/load on startup is to kernel hack, and personally for someone who isn't a developer/programmer, I wouldn't touch an opensource code with a stick

I have the same problem. The lowest brightness is still too high to read something with the lights off.

Hey, I think I actually found something.. do you have cm10? If you do, you can turn on screen filter normally then go to settings > apps > screen filter and uncheck "show notifications". That took away the persistent notification for me.
I don't know if you can do this in aopk.

i have a great solution (with a notification-so i will try your suggestion 386 once my rom is done backing up), but want to make my own personalized "build (apps, tweaks etc) thread". Where can I make it without getting slapped by the mods? In the galaxy s3 general thread or since most of it is can be done on different android phones in the the overall general thread?

Finger print LED as Notification LED

Hi guys
I was thinking if it is possible to use finger print scanner LED as a notification LED? I know it may not be currently possible but just floating the idea for the devs who make things possible all the time
I know the LED is huge to be used as notification LED but some people would love to have an LED instead of a ringtone or vibration alerts, thanks in advance for any help in this regard

I don't know if this is possible but this is a fantastic idea.

If this is actually possible it would be awesome!

Great idea, but is there really a separate LED ? I had always assumed that the FP uses the green lighting from the display itself....

Yes I thought it was like that.

I think it doesn't matter if there's a separate LED to light up the display or part of the screen itself is used as a notification LED, but I think all possibilities are there, to choose the color, random colors each time or per app, position on the screen etc...

I don't really see the point in using those specific pixels as a notification LED when any other pixels on the display work just as well. And if anything, you'd want to avoid lighting up the fingerprint pixels too much since they are being used more at high brightness and therefore more susceptible to burn-in.

I want one to do like Samsung's edge lighting. That with Pixel Pulse would be perfect.

Amy work on this?

I disabled fps on my 6t because of the annoyingly high brightness of this green circle when your finger is close!
I don't think there is a led, I saw a video where they open the 6t and access the sensor module, it's just a camera sensor under the screen, the amoled brightness is boosted in this particular part of the screen, that's all.
Thanks God they didn't use a laser light, half the people would go (really) blind.
You can use an app like noled to simulate a led anywhere on your screen.

What about this app?

Yes, that is the app that a lot of us have been using with no issues. You just have to go into the settings and tweak it to your likings.

Changing LED colour per app

Hi there
Is there a way to change the colour of the led notification light for each app in built into the phone.
If not then is there a reliable app that you have tried and found to be working well.
Thank you for your time.

You can try LightFlow app. Keep in mind the 5Z doesn't have a traditional RGB LED, it only has a Red & Green type LED notification light so the possibilities of producing different colors by mixing are limited. However some colors are still possible but don't expect much brightness in them.

Thank you for the information.

Question Notification light

So I don't know if it's on here or not but I came from a Samsung phone and so anytime a notification will go off it would flash a green light does the OnePlus 9 pro have that same feature or some type of light that could flash when a notification is on the device? Perhaps maybe there's some type of a magisk module that can utilize the camera ring around it to flash when there's a notification if it helps I am on a custom ROM. So I'm not sure if stock has it. Thanks.

On recent OnePlus phones, you'll find a function called Horizon Light (it basically lights the screen's borders when a notification is received), that is used for similar purposes, but there isn't a notification LED in the hardware.
I'm not sure if it is a function that is still in your custom ROM, but it is a stock ROM function.

Yeh, only aware of built-in horizon light , but it doesn't flash long enough to catch it....

Geez, how I miss the LED notification lights that older phones had.
Especially the ones that were multi-color so you could assign a different color for different notification types.

Technically, it wouldn't be impossible to recreate it with an app dedicated to modify the always on display features.
As AMOLED screens are basically tiny LEDs side by side, we could imagine a way to light or pulse specific ones to remplace the "missing" one. But it would be a trade-off, as those selected LEDs would be functioning and aging surely more quickly than the others.

There are a few apps out there that will use the AOD to create the appearance of a notification light or even continually flash the Horizon light bars and other custom lighting options however all 3 I've tried were glitchy and obviously drained the battery since it's using AOD to accomplish the notification light. Maybe if you're already used to AOD battery drain it wouldn't be so noticeable but I don't use AOD normally so the difference was very noticeable to me.

Yes, it's also a thing to consider, but I don't think the memory and power usage for only a black screen and a color dot would be that energy consuming. Did you notice a change that big when you gave a try to those apps?

look for notifybuddy on the playstore. works fine on my OP9Pro.

I didn't realize how much i relied on the notification light until it was gone. The AOD fits my needs, tho. Posted settings on another thread awhile back: https://forum.xda-developers.com/t/horizon-light.4371367/#post-86085187
I may give notifybuddy a try, too

Would recommend this app. I've been using it on my oneplus devices last couple of year. There are a lot customizations too.
LED Blinker Notifications

i REALLY missed my notification LED (the last phone I had that had it was my old blackberry priv) then I got a smart watch and I don't care so much anymore
