Hi, I have noticed that my Galaxy A50 could not recognise my fingerprints when I switch off external lights. Screen brightness was set at minimum. When I turned on the external lights and tried, it worked. When I turned off the lights again, it didn't work. I tried with multiple registered fingerprints. Can anyone confirm this?
Edit: I noticed that this happens only at minimum screen brightness irrespective of external lighting conditions.

I've noticed with my GNEX that it seems like all of the sudden it won't auto dim. When I unlock the device it will brighten if needed, however if I walk into a dimmer area it will not auto dim. Is this the normal behavior for the light sensor?
I'm used to my Xperia Play which would constantly adjust the screen up and down.
My auto-brightness setting sets the screen brightness lower than the lowest actual brightness setting regardless of whether I'm in light or dark.
There's a fix for it here: http://forum.xda-developers.com/showthread.php?t=1377410&highlight=auto+screen+brightness
I haven't tested that out though.

Yea I was worried maybe the brightness sensor was not working since. Turns out my wife's droid 2 with CM7 acts the same way. Lowest setting until you unlock at which time it only increases the brightness, never decreasing.
most of the time when the phone wakes up and the screen stays dim and grey, as if there is a semitransparent picture in front of the screen. I can see the clock and I can unlock it, but everything is dimmed.
If I turn of the screen one or two times, it usually wakes op again without this grey dim sheet and I can use the phone in full brightness.
I turned off auto brightness, but this did not solve the problem. The brightness slider also turns upp the brightness, but it is still about half as dim as it should be.
can anyone help me in finding out why this is happening?
Hi,
I have recently bought an RK3188 Unit (KLD6) and am happily running Malayks ROM on it. However, when I switch on the lights of the car, the unit lowers the brightness of the screen. As I have to use lights during day in some parts of Europe, I would like to manage the brightness of the screen by an app. If it is a bright day and I have to drive with lights switched on, I can barely read the screen anymore. So is there any way to prevent this behavior? I know that I could just remove the lights wire, but I would like to have the LEDs to be switched on or off with the lights.
In case of Mtcd devices such option is in Factory Settings (password to enter it is 126). You can check it in case of your unit. I had the same problem - in my country it is mandatory to use head lights 24h per day so I lost screen visibility during the day.
Thanks for your answer. However, I wasn't able to find any option to turn off the brightness control. Do you remember how it was labeled/called? I found the option to turn on the LEDs permanently and also brightness control for reverse driving, but no option for the brightness with lights switched on.
Thanks in advance.
I found the solution, which obviously was too obvious to be found beforehand by myseld. :/ The normal system settings menu provides a tab 'Display', in which the brightness can be set as 'auto', 'light', and 'Dark', whereas 'Auto' means that the brightness depends on the status of the car lights, 'Light' means bright and 'Dark' means lower brightness.
The notification led is connected to the ambient light sensor so in a dark room the led is dim, in a light room the led is bright.
However if you're out and about in even a slightly bright day and take your phone out of your pocket (which is dark) you can barely see the led because it's been in your dark pocket.
This isn't a hardware limitation, if you install Resurrection Remix or Liniage OS the led is bright all the time.
I'm running a stock based custom os because of the camera quality.
I just wondered if anybody has worked out a way to either disconnect the led from the ambient light sensor or even disable the light sensor all together... I don't use it.
I've tried the Xposed Sensor disabled but it didn't work on either BRF5 or ARC5

Turn off Automatic screen brightness? Is the LED not connected to the screens brightness level?
Ummm, actually when I said I don't use the light sensor, I figured it was obvious that I don't use automatic screen brightness (since it uses the ambient light sensor).
Anyway, no.. The led isn't connected to the screen, it's connected to the same sensor as the screen... The ambient light sensor.
You can tell the screen to ignore the ambient light sensor by turning off automatic screen brightness, that however doesn't turn off the sensor.. So the notification led is still controlled by the light sensor.
Have you tried any of the notification apps on Play or Samsung Appstore? There's quite a few free ones available on Play but I've never had the need to try any on this phone.
I've tried them all, I like lightflow the best.
They let you control the brightness up to 100%, but that's 100% of the brightness controlled by the ambient light sensor which in turn answers to the Samsung software.
*Sigh*, if I can't find an answer, I might take my balls in my hand and open one of the phones and physically disconnect the sensor.. It's only a cable with a plug.
I also have an S8+ and it does the same thing.

LOL, if you do let us know how it comes out.....the sensor not the balls.
Has anyone solved the troublesome problem?
Hello all,
My baby son managed to damage the flat cable going to touchscreen and ambient light sensor (don't ask how, watch was on my hand) and now touchscreen and light sensor are not working.
Brightness is on low setting and I can't change it.
Is there any way to change the brightness via phone?
I would like to set it to higher level to be able to see anything during the day, until I get a new screen.
I've tried "Watch Display Brightness" app but it's not working. I think that issue is that brightness is not set to manual mode and that's why this app gives no results.
Thanks!
