CF.Lumen interferes with fingerprint sensor - Samsung Galaxy Tab S6 Guides, News, & Discussion

I'm using CF.Lumen v3.72 and noticed if a filter is enabled the fingerprint sensor won't recognize my finger nor am I able to setup additional fingers.
Anyone else experience this?

Workaround:
Used Tasker to disable CF.Lumen when screen is "OFF" & enable after screen "Unlocked".

Why are you even using CF.Lumen? The built in night mode has pretty much the same features, and won't interfere with the fingerprint reader. Not to mention CF.Lumen hasn't been updated for almost 3 years now.

CF.Lumen is still way better, more fine control/colors & has dark red filter mode for pitch black reading environments.
The built-in blue light filter is not enough, too basic, best only a subtle tint, but I found a workaround for CF.Lumen so all is well.

CF.Lumen also hasn't been maintained in 3 years, meaning it will interfere with more and more systems - the fingerprint reader being the first of many.
You can try workarounds, but it will always be hacky, and no official support will be given.

Screen dimming app.

If any of you other users out there feel that the whites on this thing are too awesome for super late at night like I do, I found a app when searching for a f.lux type alternative for android. I have been using this app to help ease the stress on my eye late at night. I dont know about the techical side of what it does, or any of the jargon involved, but it applies a filter of sorts to dim the screen further than what the phone allows. I been using it a lot lately and figure I would share with you guys. If anyone has any recommendations for other similar apps, please share.

Or just turn on "Background Color" in Power Saving Settings.
Or if you want the screen brightness itself to be lower than what most ROMs allow, you can use this app called RootDim. It worked amazing on my xoom, not sure if it works on the SGSIII yet..
It requires root though..

Screen filter does the same and doesn't require root. On our AMOLED screens this can save battery.
Also you can turn off those damn capacitive key lights by going to Settings>display>"touch Key light duration"> Always off.
I can confirm that Root dim does work for the SGS3 I use it on my phone.

Lux is an amazing auto brightness app and setting it up for your tastes is incredibly simple.
Go out in the sun and turn brightness up all the way using the app then "link" that setting, go in complete darkness and set it to your taste and link it, then indoor lighting, set it, link it. It then uses just those 3 settings to create a smooth graph of brightness values that are all perfect. You can have as many links as you want but i find the less settings you put in that app the better.
I tried all the suggested ones in here btw.

I've tried and really like Lux (in fact I'm considering purchasing it soon) but I've noticed two issues. First is that sometimes it will not refresh itself and I have to open up the lux dash to get the brightness to change. It doesn't happen often, but it happens often enough to be annoying, and I have it set to automatically.
Also, (and this may simply be an issue with the S3 and not lux itself) but sometimes I will be in a decently lit room and be at 1 lux, while lights out is 0. Not a lot of variance unless it's really bright outside. Have you found anyway to increase the light sensors sensitivity?

Try setting it to be always active in the task bar, that prevents it from being killed. Also try setting it to not use raw values for light sensor readings, this gives you a simple scale of 0-10 for readings and total darkness always reads as 0.
Edit: oops reread your post. That's weird that it is reading indoor light at 1. I usually get around 2 or 3. I used to have a screen protector on that covered the light sensor and that put it all over the place. Maybe that is what's causing it?

I noticed the same behavior with the free version. In my case, the lowest value the HTC Desire S can reach with its default Android auto brightness is in fact about 15%.
In LUX settings you can configure the "0" value to be lower and "bypass" the freeware limitation (you can't configure sub-zero levels in the free version). This will work when you test it in the dashboard, but during regular use the light level never goes below the 15% limit already set by the OS.
What I did was purchase the full version (to get astronomer mode along with all the settings unlocked) so I was able to leave the 0 level at its default 15% but link some light intensity values to sub-zero percentages. Guess what? It works great! Once you go into a very dark room, the display dims as far as you set it to.
Another problem with the free version was that a few times I unlocked the phone outside in full sunlight and LUX did not increase the brightness. It appeared almost completely black because the light level was at about 15-25% (the same level it would be inside a low lit room).
Again, with the full version I did not notice this problem (I've used the free version for 1 day and the paid version for 1 day but running tests in different light levels inside and outside).
It's like the free version is a bit buggy on purpose, and I remember uninstalling LUX free about 2 months because of this; I was thinking that if the free version does not work OK, I shouldn't buy the full version. Apparently this is not the case (touch wood).
Just for the record, it's on "dynamically adjust".

If the display is a bit dirty (oily, dusty, etc) around the light sensor, you can try to clean it. If this is not the case, open the dashboard, let it determine the light level or hit "auto" a few times and make sure the reading is correct. Then just slide your finger along the yellow line to find the appropriate brightness level and long press the chain to link. Go to a brighter lit room then go back to the first room and see how LUX behaves. Also lock/unlock the phone a few times and see how it goes.
If you still have problems running LUX, disable it and check the default Android auto brightness to make sure it's not a sensor issue.
LUX also has the possibility to set the response delay under Settings -> Advanced -> Developer Settings (the last to just on the bottom, but for this you would need to buy the full version.

Thanks, but I think it is more of an issue of the sensor not being sensitive enough. I'm not sure if this is anything you can change in lux or if it would have to be edited in the kernel (or if it is fault of the hardware) but I just feel like the sensor doesn't go down low enough. As I said, I can get down to 1 or 0 in a decently lit room, and yes I have tried cleaning the screen. It's not like it jumps around or anything so it's not like I would notice anything in default auto brightness, it's just that it doesn't seem to be sensitive enough.
Screen filter is great!! I use as well!!!

Well for my Desire S, the lowest light level that the sensor can read is 160 lux (raw value). You can try and set LUX to use raw values because this is more accurate in my oppinion.
Another +1 for Screen filter here
Does anyone know how to use "luma" values for automatic adjustment in Lux instead of "lux" values?

What I have noticed on my phone is that "luma" readings are taken from the front facing camera, while "lux" readings are taken from the ambient light sensor (you can chose which one to use in the settings).
I suppose the front facing camera uses more battery than the light sensor; it also appears to be more sensitive because it can read more light levels.

I guess so. Thanks! But doesn't that kinda defeat the whole purpose of Lux? Because you can't use automatic mode with the camera(s).... so then what's it good for?
Well even if you don't have an ambient light sensor, you can still use the camera to check the light level when you unlock the phone and let LUX adjust the brightness level. Of course it's not dynamic but it's still better than having the brightness at 50% the whole time or changing brightness levels through a widget..

Is there a way to keep the screen always on ?

Hi!
It may look strange, but I really would like to keep the screen of the gear watch always on, at the lowest possible light setting and that when the watch detects the wrist movement, the light settings come back to the normal one.
I'm sure this will add up to very low battrey life. But if I can get a day like this, it would be great!
Thanks!
I wanted this at first, because coming from the Pebble -it's just so convenient having the screen accessible all the time and the gesture doesn't always register.My idea was that it should just be a very minimal screen in terms of pixel use to leverage the power saving qualities of the AMOLED tech. Problem is, the AMOLED screen is also known for burn-in on the phones, so I'm afraid even if we set this it would damage the watch screen in the long run (and I would be ok if I only got a day of use also, as I'm fine charging every night anyways).
There is a watchface called "AlwaysWatch" in the Samsung Gear store that's supposed to give you an always on face until the battery runs out. Problem is, it runs as an app instead of the default face and of course I'm afraid to try it due to the burn-in issue. I sent the developer a note saying make the watchface a small, but still legible digital font instead of analog and float the time around the screen periodically would get around this burn-in risk, we'll see if he adds the option.
Thanks for the info on this app (I also have a pebble ).
In order not to burn the screen, it would be preferable to change the watchface form time to time and put it in the lowet light possible...

One of my disappointments besides the flaky gesture wake up is that there doesn't seem to be an ambient light sensor to trigger screen brightness changes. I would have thought that would be a no brainer for a device such as this by now.

Maybe the camera light sensor in the Gear 2 could be used for that purpose?

[APP][2.3+] Auto Brightness - app for phones without light sensor

Hey everyone,
I would like to present you app that I created to automatically adjust screen brightness. Tested on LG K8, Android 6.0. App is using front camera to determine lighting in smartphone environment. I created it because I recently changed my phone and as it turned out this one does not have light sensor, and that was cumbersome for me (day or so after using phone I faced situation when I was outside, it was very sunny and brightness was set to like 10%. It was impossible to unlock phone because I couldn't see anything on screen even if I tried to cover phone screen from that light, so phone was totally unusable!). I didn't find this kind of app on Google Play so that's why we have this thread.
FEATURES:
- automatically adjusts screen brightness
- automatically turn on device boot
- 5 frequency options
HOW TO USE:
1. Download.
1.1. [6.0+] Give permissions.
2. Choose one of available options (I recommend using medium refresh rate).
MORE INFORMATIONS:
Of course app will be improved. I want to add notification with brightness adjust bar, and improve algorithm that is determining what brightness level will be set.
FREE DOWNLOAD:
App in attachement.

Thats good for device doesnt have light sensor
Great idea... However on my k8 its a bit confused... i tried it in the office during daylight, it was quite dark instead of bright and when i covered the front camera its become bright... maybe you could put some options there to manually adjust intesity levels related to the picture brightness?
Good idea

Disabling ambient mode dimming

Hello, new user here, I got a Watch 2 Sport after a few years with a LG G Watch R.
I was surprised to see that the screen seems to have 4 modes, instead of the canonical 2 modes (ambient mode and interactive mode): after a few seconds of inactivity in interactive mode, for a second the screen dims while still in interactive mode, then transitions to ambient mode, while still being dimmed. When woken up again, it "undims" itself while still in ambient mode for a second, then transitions into interactive mode. Picture explanation: https://i.imgur.com/0mUcIyb.jpg
The main problem I have with this is that the "dimmed ambient mode" is really dim, and basically makes the ambient mode useless except in very dark environments... Does anyone know of a way to disable the dimming or, at least, set the brightness level of this dimmed mode? It seems to be unaffected by the screen brightness settings...
I use a custom watch face, so even if the solution involves changing some code in the watch face it would still be very welcome; however, I have not found any mention of this "feature" in the android wear documentation...

which custom face app do you use? i've used watchmaker, but that doesn't seem to dim - just pauses the second hand. thus, I'm stuck using the stock watch faces, as the dimmed look is classier/more practical, but the regular faces are not very good.
I don't use anything like watchmaker, I use a watch face that I developed from scratch in Android Studio... By the way, I tried installing Watchmaker and I tried one of the free watch faces, and it does, indeed, dim (https://i.imgur.com/q3pGRWi.jpg), so I'm not sure what you mean.

i'll send some screenshots later this week. but I'd like the watchmaker face to dim like stock.

so yes, technically, you are correct - it does dim. I guess I meant for it to transition to ambient mode like stock. does the one that you developed to that? i've been looking for a watch face like stock, but with a more legible calendar widget.

I have a display issue. Please someone confirm me that is normal or not?

Hey there, I recently bought the OP8. Sadly, my display have an issue.
Get a dark grey image. I used a dark grey image from google image search.
Set brightness at 20-30%, auto brightness off, DC dimming off, screen calibration to natural.
Display the dark grey image, make sure it cover fullscreen.
The issue is, which can be seen more easily inside a dark room:
The under-screen fingerprint sensor is visible as 2 overlapping rectangles
Photo attached ..
Please someone confirm me that is normal or not. Can i continue using the phone? Everything else is great. Just this issue. Should i keep the phone? I Got it from online unofficial , so It's gonna be difficult to claim warranty. Thank you
This is normal. All fingerprint readers for all phones that sits under the display are visible if you just find the extreme colour setting, light setting, angle, sun light or whatever far-fetched, never used setting needed.

This is normal, the rectangular portion will be translicent so that the reader behind the screen can register your finger print. for the reader to see your screen it needs that window.
Congratulations you have a FingerPrint reader.
