There appears to be a certain brightness number below which the MT4G simply turns off the backlight. I experienced that when fiddling around with AdjBrightness, so beware. It's just a quirk of the way the software and hardware interact.

Yeah I've experienced this too. Right around the lowest 25% does it turn the backlight completely off.

Let me guess, you running miui. If you are, I'm pretty sure its a known issue.

In fact by playing with juicedefender, I had those experience before. When set juicedefender-->advanced mode-->brightness to a certain level, then put brightness in CM7.1 to lowest brightness, it will turn off screen. Play around with the settings, and find a perfect level for brightness.

thnx
thank you guys your feedback really helped me understand that i am not going crazy, btw this is happening in CM 7.1

Capacitate buttons ?

OK guess in having my first problems? Today my capacitate buttons at the bottom of the phone have just started going out on there own. Literally while I'm typing this they have come on and went out like 5 times now. Is anyone else experiencing anything like this? Weird cause up until now I have had zero problems with my phone. Maybe a sensor having glitches?
Are you typing in landscape mode?

No portrait ...right now they won't even come on? Like they all of a sudden have a mind of their own LoL
have you tried covering the light sensor by the speaker grill? The button lights are brightness sensitive, so by covering the sensor, they should turn on. Otherwise, I would guess there might be a problem with your auto brightness or the sensor itself. When I first got this coming from a captivate, I was confused since the captivate turned them on when you touched the screen.

Yep tried the light sensor and a battery pull as well. Now they won't even light up? Not like its a killer dealbreaker for me or nothing. Just weird they all of a sudden went crazy?
Now that you mention it I've been experiencing the same issue with my atrix2. Its like the buttons have a mind if their own.

Yeah, mine come on when they want to. Right now they are off.

All moto phones do this. The software for the light sensor is just REALLY bad, so there is really nothing we can do about it, unless a dev wants to help us out.
Well it really just started doing this today. But after playing aroung with the display settings I'm thinking the light sensor is either going bad or is bad. When I set it to auto brightness it gets dimmer then the lowest manual setting in a completely dark room. Oh well, like I said not a killer deal for me. Just never had one fail quickly like this.
try turning off auto brightness and see if they still do it

I never use auto brightness its always set at about the lowest brightness on manual. I've played with it back and forth and think the light sensor is just acting up.
Wow, I hope that's not a widespread issue.
My A2 doesn't have that problem. It's quite new but I think it's my 4th now (I've lost count of how many times I've seen a dead pixel on that otherwise gorgeous screen) and I do remember the capacitive buttons' backlight doing weird things on my other Atrix(es). I can't remember if that was on my OG Atrix, or if it was on one of my A2s in a car and the lighting kept changing, or if it was an actual problem.
But anyways, the light sensor works pretty well for me on my current A2. I usually have it on auto-brightness.
Mine work perfectly on manual or auto.

A couple CM10 related questions

Hi all. Currently running the 10.25 nightly, and I have noticed a couple strange bugs. I would have posted in the big CM10 question thread, but it seems sort of dead at this point.
First, when I turn the screen on when the phone is locked, it starts off dim for a couple seconds and then goes to the correct brightness. Not a huge problem, but definitely annoying.
Second, when scrolling through tabs or windows, and sometimes swiping up and down, I see flashses on the screen of what looks like code or the matrix or something. This is especially pronounced when using Handcent, where whenever I push a key I see the keyboard flash on the screen above the normal keyboard, making scrolling through messages and the message list quite annoying.
Any help would be greatly appreciated.
Are you using auto brightness?
And, is the second thing you are talking about screen tearing?
Are you using a custom kernel or stock

I'm mostly a Sense guy. But the AOSP base ROMs I've tried all do this. When you turn the screen on, it kinda "fades in" instead of turning on right away to the set brightness (this is with auto brightness turned off). Seems completely intentional, and I personally couldn't find a way to turn it off (as I don't like it either).

Yes I am using auto brightness. I'm using the custom kernel that comes with CM10. It's sort of like screen tearing, but it's more of a flicker in the background and is not always noticeable. Much more obvious in Handcent, though that might be a separate issue since it's the keyboard flashing in the background.

App for locking the screen brightness?

Hashcode and twa_priv both have great ROM's out now, that work wonders with the battery drain in standby. One of my kids gets -15 or less drain when in deep sleep now. Amazing.
But my other daughter, hers keeps spiking up over -120 and higher while using the same rom. I saw that the screen brightness cant be set to 100 or the screen doesn't fully shut off, and that is exactly what is happening. I can still see a dim backlight sometimes when turned off.
I keep changing it to a lower setting, and then she gets great battery life for a while, then something is changing the screen brightness back to 100. She isnt doing it, because I grounded her from it for a couple days, and it still did it when she wasn't even playing. So I wiped everything, clean installed the 01/08 rom fresh today, and it still does it.
Is there an app that will lock the brightness for me? I cant seem to find one.
Thanks!
I had that same issue on my KF repeatedly and found that it was from build.prop changes. Switched to Paranoid Android and the in notification brightness slider has been perfect and the screen off/on issue never came back.

Cool, thanks for the tip!
Once I studied this Kindle closer, you could see the screen backlight come on for a few seconds, then back to sleep, then back on, and back to sleep. A clean install of the latest rom from twa_priv seems to have fixed the problem, he reverted some kernal changes that were causing problems for some users.
Funny that you are in Eustis, I live there and in Mt. Dora for a while, back around 1988 to maybe 1993. I am in Ocala now.

[Q] Hardware Key Backlight Settings

My GS2 had a charging port problem so I pulled a spare Nexus S 4G out of my desk, flashed a CM10.1 nightly and have been happy ever since.
I have one thing I would like to change.
I understand that I can't modify the brightness of the hardware key backlight. Can I change them so that they stay on the whole time the screen is on? Once they turn off, I can't see the buttons at all, even indoors.

Yes, disable BLD in Settings > Advanced settings.

That did the trick. Thanks.
It was about the only thing I didn't try was moving that slider. I thought it would just decrease the time the backlight stayed on.

[Fix] BLACK SCREEN OF DEATH

What is black screen of death??
Plz google it.
For those who are facing this issue.
I was also facing the black screen of death issue from past 3 months.
The only way to avoid it was through rebooting the device.
And by searching web others recomended to replace the flex cable.
Solution:- guys now i am not facing this issue by keeping the brightness greater than 5/10 (>5)percent.
I have tested this persnally for 10 days and i have not faced black screen of death till then.
But when i reduce the brightness to 0% i start experiencing the black screen of death.
I dont know properly what incresing brightness does.
Permant fix can also be done by increasing the minimum brightness value. (I dont know that hiw to do). May be devs can help here.
Those who are facing black screen of death keep your minimum brightness at or above 10% that will fix it.
Will try.
What ROM?

I got the same problem with my nexus 5 too. After lowering down brightness to below half somewhere, the phone screen shuts off but the phone is still on and if i blindly drop down the status bar and increase the brightness by assuming the slider there, the screen again turns on
One thing to note that my screen does not have any dead pixels or display problem at all because I tested it. Also when the screen turns off the task that was carried out on the phone still stays i mean that when i play game at night and lower the brightness, then the screen turns off but i can hear the sound of the game running.
I have tried many roms but the problem still remains.

Try changing the rom which has this issue fixed at around 10℅ brightness.
Bcoz above 50 ℅ is. Huge for battery drain.
I am currently on santosh m 7.1.1 15/12/16 build and i am not experiencing black screen at 10℅ brightness.
Since you play at night ( night modde will also help ).

I have tried Santosh ROM it's still there, but the thing is that this problem I am having was even on the latest stock ROM (till android 6.0.1 Dec).
I don't know why it happens.
