Brightness to zero - Hard or Software bug? - Nexus 4 Q&A, Help & Troubleshooting

HI!
Yesterday i set the brightness of my nexus 4 to 0 (with the slider by
shifting it to the left position). Surprisingly this turned my screen
off, while the touch pad still works. By using a bright flashlight i
was able to set the brightness level to a normal value again, but i
think this is not supposed to happened anyway. A friend of mine has a
nexus 4 too and he can set the brightness to zero without turning off
the screen. Is this a hardware bug and must i be worried about it or
is it just a software bug?

[Q] physical keyboard issues

does anyone else get an issue that the G2's backlight for the physical keyboard and capacative buttons have absolutly no idea when to be on and when to be off. I can be in a fully lit room and have the backlight on for no reason at all. is there any way to fix this? it gets very annoying very quickly.
It's a problem with the light sensor, but I think it can be corrected with software. The sensor seems to reflect differences in brightness really well, but the software tends to set everything to levels appropriate for brighter conditions. This leads to full screen brightness and no key backlighting even under dim interior lighting conditions.
my screen is SUPER Bright regardless of ambient light (in automode) I rely on the manual settings.
and yes I do have the same problem ... even on my second g2.
Same here. My backlight and softkeys go on and off randomly while in bright light and checking the time while waking up briefly during the night is painful because it is always extra bright.

thanks swags. hoping for a software update soon. its really annoying. also is it normal that i get this issue even without auto brightness

Auto brightness only brightens, never dims

I noticed that the brightness only brightens but never dims back in automatic brightness display setting. I can reproduce this easy with turning the lamp on my desk on and off. It only goes back to the lower brightness if turning the screen off and on again.
Noticed this too but seems to only occur when I use a widget to toggle between Auto and 100%.
If I leave the setting in Auto from within settings then it seems to work. Brightness widgets seem to break the auto functionality.
Hmm, I don't use a brightness widget. The light of the softbuttons go on if I cover the light sensor, but the screens stays in high brightness.

Must be an all around bug then. If you turn the Atrix off and back on then the auto brightness functionality is restored.

This must be an Android thing. My Atrix does the same thing, as did the Nexus One I had before. I've had several (high end) Nokia's that dimmed/brightened perfectly. After 5 seconds, they would brighten (or dim) accordingly. I was hoping Motorola was better at making phones than HTC (the KING of bad battery life). We ALL lose here. Our precious battery life is being drained by the poor execution of a simple function.
This is a stock android thing (problem). Custom ROMs can allow it to dim and change brightness smoothly rather than in discrete steps (Cyanogen).
That's what I thought. I found this free app called "esdimmer". It supposed to be for Galaxy phones, but it's somewhat working on my Atrix. Does this function work any better in Gingerbread?

Well it's good to hear that it's a stock android problem and not the actual phone. I did find a way to get around this problem but it's very limited. You can get the screen to dim by first putting the phone into standby and then press the standby button once again (which gets you into the lock screen). You'll notice that the screen then dims (if coming from a well lit area/room to a darker one).

Brightness all the way down = screen turning off

Anyone else seeing this?
I could have swore that on my first Nexus device (RMAed due to bad speaker), I could turn the brightness all the way down and use the tablet on the lowest setting.
On my new Nexus (no issues so far), if I turn the brightness dial all the way down, the backlight totally shuts off, causing the screen to be impossible to be seen.
I'm not RMAing this one because it's perfect otherwise, it's just very weird behavior
I got the brightness on mine all the way down & the screen isn't off.

Did you find a solution?
I have the same problem. If I turn down to minimum brightness (10% or less) my screen goes black. The only way I can see what's on the screen is if I shine a light, and then I can barely make out what the screen says. I assume this is an easy software fix. Also, if auto-brightness is on and I'm in a dark environment the screen will occasionally dip to the lowest setting and turn off.
I'm on my second device also. My first one had bad screen lift, flickering and occasionally screen glitches with black lines flickering through the screen. This one had no noticeable screen lift out of the box, but I'm reserving my judgement, as the device I just returned was fine for the first few hours and then got worse as I used it more.
I have both devices side by side, since Google mailed me the new one first. Comparing the two, I notice the old one's screen is slightly brighter, maybe about 10% or so, but definitely noticeable. Also my new one has a little bit of bleeding on the left side; not terrible as some pictures I've seen, but definitely there.
Update: The screen flickering returned, so I just requested a second replacement. This is actually ridiculous.

s7 edge screen flickering

i recently bought a used s7 edge. the cellphone's display is damaged buf overall it works fine. except for a few issues mainly related to light sensor according to my understanding.
1: the display flickers when auto brightness turned off or when brightness is set to anything less than maximum
workaround: i installed screen filter app to control the brightness
2: the screen goes to green screen of death when device is put to sleep
workaround : turn AOD to always on and never Turn it off
3: the display goes to green death screen during call and wont get normal unless call is ended and screen is locked and turned on..
4 : at AOD ,the screen flickers at night time or in a dark place but gets back normal in bright light..
info i need : i thought what if it was possible to change the android framework values for the light sensor so that no matter whatever the light of the surrounding may be.. the device will always think it's in bright light.
for example if the settings for current values are
high 5000 medium 2000 low 600
then i change it to
high 1000 medium 500 low 25
so that the device will always think its in full bright area..
can anyone help me in achieving this goal? thanks

Screen too Bright even at minimum brightness

Screen is too bright even if you set brightness slider to lowest value .It makes really painful for eyes to use the phone at night.
This issue was not in Android 9 .
Tried resetting device health service app but that does not work.
Was facing the same problem, as a workaround I am using below app:
