Has anybody else experienced their screens changing brightness randomly?
I have mine set to full brightness and it will randomly get slightly dimmer for a few seconds up to a minute before going back to the original brightness.
It's sorta hard to notice unless you're looking at an image with a lot of white (Play Store, webpages, etc.)
My first N5, which I RMA'd for other defects, also did this.
Any guesses if it's a software or hardware issue?
Derp, just found this thread that answers my question: http://forum.xda-developers.com/showthread.php?t=2516915

Hello everyone,
Received my MotoG a few days ago, it got updated immediately to KitKat after turning it on, everything is fine except one thing: with auto brightness disabled, and the slider set to the minimum, I notice slight screen flickering on white backgrounds. When I enable the auto brightness, even in dark rooms, the flickering goes away, if not totally, 99%.
With Wi-Fi and 3G disabled it's still the same. I know that KitKat on the Moto G modified the minimum brightness coming from Jelly Bean, wondering if that may have something to do with it.
Anyone noticed (or can verify) the same issue on the Moto G?
Thanks in advance for your replies,
Gabriele
Here's my conversation with a Motorola customer support representative:
Code:
Jahmila: Hi, my name is Jahmila. How may I help you?
Gabriele: Hello Jahmila. I received my new Moto G a few days ago, everything is fine with it except one thing
Gabriele: with auto brightness disabled, and the slider set to the minimum, I notice slight screen flickering on white backgrounds. When I enable the auto brightness, even in dark rooms, the flickering goes away
Gabriele: With Wi-Fi and 3G disabled it's still the same. I know that KitKat on the Moto G modified the minimum brightness coming from Jelly Bean, wondering if that may have something to do with it.
Jahmila: Does this happen also when using the Chrome browser?
Gabriele: I know about that bug with Chrome, and it's not that flickering
Gabriele: the flickering i'm talking about is like a slight decrease-increase in brightness, it's continuous
Jahmila: Does it happen when the phone is in Safe mode?
Gabriele: hmm didn't try this, how do I reboot it in safe mode?
Jahmila: start the phone up in Safe Mode by pressing the power key then pressing and holding on Power Off, you will then be asked if you want to start the phone up in Safe mode, select OK. Safe mode temporarily disables all 3rd party applications so you can not see them - they have not been deleted. Use the phone in Safe mode without starting or installing any 3rd party apps for 24 hours or until the issue appears again
Gabriele: I can try right now, bare with me for a minute please
Jahmila: .
Gabriele: so, with the phone off, should I just keep the power button pressed until I have the question about the safe mode?
Jahmila: No. When the phone is on and you press the power key ou get differnt options. Amongst the: Power off? You thn press and hold on power off and will then be asked if you want to boot up in Safe Mode
Gabriele: aha, got it. just a second
Jahmila: k
Gabriele: yes, it does happen in safe mode too
Gabriele: it looks like the screen is driven by PWM technology, at extremely low brightness that technology can generate flickering
Gabriele: now I enabled auto brightness, i'm in a dark room. The brightness is higher than before, and I don't notice any flickering
Jahmila: my advanced technicians confirm that this is considered manufacturers tolerance meaning that this may occur on a device but is suck a minor issue it is not considered a fault
Gabriele: I know that with the latest software update the minimum brightness of the moto G has been turned up, could it be that Motorola wanted to increase the tolerance?
Jahmila: Yes the brightness has been increased as there were complaints that the brightness was too low
Gabriele: is there any way you could remote the device and check if the value of minimum brightness corresponds to the standard, or if it's too low?
Gabriele: because as we speak, the minimum brightness is very dim on my device. as I turn on auto brightness, it does increase quite a bit
Gabriele: so maybe motorola only tweaked the autobrightness parameter, instead than the manual brightness?
Gabriele: I didn't check if the device had the problem under Android 4.3, as I got updated as soon as I received it.
Jahmila: could be, we really dont have that kind of detailed information on a end user customer service level. i can however confirm that your device does not appear to be faulty and is working as designed. We will of course pass your comments along to the relevant department for future consideration
Gabriele: could I be put in contact to a higher level maybe? in order to discuss this behaviour. Or if you have a Moto G sample around, could you check if you notice flickering at minimum brightness aswell?
Jahmila: We have checked, that is why i could confirm this
Gabriele: ah so you've seen the same?
Jahmila: not on this device , but again, it has been confirmed as a manufacturers tolerance. it is a small pay off to appease a larger volume of customers who were dissatisfied with the brightness previously
Gabriele: so actually there is no way to know if this "brightness adjustment" was applied to the manual brightness or to the auto brightness?
Gabriele: when going from 4.3 to 4.4, I mean.
Jahmila: No, that is correct
Gabriele: it would be interesting to compare a device with 4.3, one with 4.4, set them at the minimum manual brightness and see if they have the same level
Gabriele: if you could come back to me with this information, that would be really helpful
Jahmila: I will escalate your requestbut can not guarantee outcome
Gabriele: ok, thank you in advance for that
Jahmila: thank you for contacting Motorola and taking the time to provide your comments. Is there anything else I can help you with at this time?
Gabriele: no thank you
Gabriele: have a good day!
Jahmila: Thank you, the same to you, bye!
Could anyone try to compare the minimum manual brightness between a Moto G with 4.3 and another one with 4.4?

some slight flickering (rapid and short brightness increase/decrease) is sometimes noticeable also when typing on the keyboard
Yes, I have this issue with my GPE moto g, it happens on minimun brightness and it is noticeable on a white background (you need stare at the screen carefully), and it is even more noticeable when the phone automaticly lower the brightness before it sleep (on bright background).
:crying:
Hi Folks,
This issue happened a to a few times now within a short time frame. The problem is like this:
I set the brightness slider somewhere about 30-40% and have the auto mode on. This way the min brightness would not fall below the slider point (I assume and this is the way I had with all my andorid phones) and works quit well.
The issue I encountered is that the brightness slider would go down to minimum (auto is still there) on it's own and stay there. I didn't have any power saving options turned on as the phone is still burning in.
The only time I noticed this is in the evenings and night. Still wondering what's causing it.
Game service is disabled on my phone.
Regards
Asanka
Auto brightness works differently in the S7 compared to other Android phones. Auto brightness actually moves the slider for you. If you keep adjusting the slider to where you want it in different environments it should "learn" your preferences and automatically adjust the slider to what you would put it at for each environment.
Thanks for clarifying that. Thought mine was buggy.
Yea that threw me off at first also
Has anyone else had issues with their Adaptive Brightness not working. Toggling the setting has no effect on my display. For such an expensive phone I expect things like this to work.
Yes, it doesn't work that great for me either. I mean I can see it adjusts the brightness "somewhat". But it appears it is not nearly as dramatic as on my Galaxy S7 which would pretty much perfectly adjust the brightness.
I agree that a phone this expensive should do it correctly out of the box. Google please listen.
This is the intended function as I understood it, so I googled it and here confirms. This is not intended to operate the same as auto brightness many other phones use.
In Android L, Google's introduced a new feature called Adaptive Brightness that combines manual and auto brightness. You can manually adjust the brightness level to a state you like. Once it's set, your screen will adjust based on ambient light so it stays at the same brightness relative to the light around you. This way you can set the screen to your preferences without sticking to an absolute level.

Been this way a long time. Would this be your first Nexus/Pixel phone?

The problem I have is that every time the phone is rebooted, adaptive brightness is set back to Off, even though it was On when the phone was restarted. Running NDE63V and not rooted.
I have this great phone since a week now but what is really annoying for me is the automatic display brightness mode. Since the sensor is in the middle of the buttom, it is often hidden by my hand and the display brightness is too low.
Is there any trick to improve this behaviour without disabling automatic mode completely? Something like a minimum brightness level (probably time based).
Or am I the only one with this problem?
Since the OTA last week, my auto brightness is determined to set itself to minimum almost every time I turn the phone on. Even in direct sunlight. Really annoying bug.
