[Q] Slight screen flickering on minimum brightness? - Moto G Q&A, Help & Troubleshooting

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).

Auto brightness very bad/too dark.

I'm not sure what it is with this phone's auto brightness but comparing it to my old nexus 5 I can see that this phones screen is always darker. I know autob its working because I sometimes see it change automatically but its just always set to be way too dark. I
f anyone else has this problem or know how to fix it without having to manually adjust the brightness that would help a ton.
Also if you changed your lux levels please post those.
On and also I do have the official screen protector on if that matters.

Yes, it is a little dark, you can go to settings/display & light and hit the little gear icon, hit adjust and set up the screen brightness you like depending on the ambient light.
i am facing that some time while scrolling brightness increases for some millisecond and come to normal. i found that is twitter, some huge page in browser page.
can any one tell what could be the issue hardware or just a software bug which can be fixed with other rom installation.

Adaptive Brightness Does Not Work

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.

Oneplus 6 auto brightness issue

When auto brightness is enabled and I'm viewing the phone in direct sunlight, the maximum brightness seems to change really quickly. It brightens and dims quickly, almost qausing a feeling of screenflicker.
With auto brightness off, the problem is non existent.
It only happens when the phone hits 100% brightness. Anyone noticed this. And is there a solution other than turning auto brightness off?
Yes I noticed this today just got mine today and sat out in sun with auto brightness on it was flashing like mad ,

For me autobrightness is useless. Simply too dark in all conditions. Also max brightness is not enough for when you have direct sun on the screen.

I have noticed the same, it's usually too dark for my taste.. would be nice if you could config how dim it goes automatically.
O saw the flickering in sunlight as well. Probably a bug
I finally gave up and installed the Lux app. Hopefully they will solve the issue in the next updates.

You're all insane. This phone has the best auto brightness I've ever used. It's very responsive without changing so fast that it becomes an issue in flickering light conditions like walking past trees where sunlight filters through or something.
I have the same problem, yes.
OLED displays have two "maximum" brightnesses; the normal maximum, which is intended for full-time use, and High Brightness/Sunlight Mode, which maxes the pixel brightnesses out for temporary outdoors full-sunlight usage.
The OP6 might have the threshold for what it considers "full sunlight" set too high, which would cause a lot of flickering in the event that the phone isn't held perfectly still in sunlight because of the light sensor output dancing back and forth across the threshold.
There's probably no changing it until someone rolls out a custom kernel in which it can be disabled or tweaked, in the meantime you can find auto-brightness apps on the Play Store that let you set custom curves (note that this'll probably require root). Hopefully OnePlus will fix it in the stock kernel themselves, terrible auto-brightness can make or break a phone in my opinion : \

I would not hold your breath. It was an issue on the 5t and not sorted during the time I had it.
Can't say I've noticed the issue on the 6 though with adaptive brightness mode enabled
Couldn't agree more autobrightness seems too dark on my op6. Under direct sunlight, I have to disable auto and full the bar myself..
Auto-Brightness is too dark for me too... Hope OnePlus will be updated this, or add the possibility to adjust the Auto-Brightness.
The minimum auto-brightness can be adjusted from the slider, it will still be auto increasing when needed but it won't go below your threshold.
I'm testing this for a few days and it's working perfect, the minimum was also to low for me initially.
I've tested the auto-brightness with a flashlight:

EVERYONE WITH BRIGHTNESS ISSUE,
There are No problems with screen, it's flawless.. Although people dealing with auto brightness issue,should disable the night mode.. Cause when night mode is active, auto brightness tends to use more dark screen as dark as possible..
Regards.

I never said I have problems with the screen. Auto brightness is causing issues at Max brightness.
Night mode is off. Thanks for your comment though.

Actually I like yellow tinted screen(warm colors) , for that I enabled night mode. Since then I was facing problems like too dark in direct sun on auto brightness. Too dark even in room. Today I accidentally turned off night mode while showing handset to my friends.. And voila brightness got up nd up nd up... I tried in direct sunlight, now I don't have any problem viewing my handset even after wearing shades..
If there is still problem in ur auto brightness then bro I strongly suggest u to compare ur handset with other op6 cause it could be a manufacturing defects... I heard a developer got flickering issues, he returned handset..
Regards.

Nope. Is bad
I have auto tightness issue also. Have not noticed flashing, but screen dims often. Even when using phone, and in a steady lighted area such as indoors.

Automatic Display Brightness often too dark

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.

Same problem here in outdoors, is there any fix?

Display is slightly blinking in specific conditions

Yesterday i noticed something strange in my OP7p and i'd like you to check whether something like this occurs in your phones. Issue, which i will describe occurs only when i have 90hz refresh rate set and the low brightness of the screen with the auto adjustment of brightness turned off. The easiest way to see that is on youtube application with a dark theme. When we start a movie on the full screen (horizontally) and watch it for a few seconds, then go back to the vertical position, there is something like weak but visible blink of the screen, or a minimal colours change. It can be noticed in other apps, e.g. on facebook. Seems to me this is a software problem, beacause the same phenomenon doesn't exists when we set 60hz refresh. I would be very grateful if you can check it on your phones and give me a know about it.
I don't usually start videos in full screen mode and never noticed it but yeah definitely does a white flicker.
This is the highest brightness I could get it to do the flicker at.
Thank you for an answer. Personally i am able to see this flicker on a little bit higher screen brightness, but maybe its because im sitting in a dark room now. I was worried cause sometimes i see it during the normal usage of phone, and if only my OnePlus would be affected by this flickering i could still return it or exchange for a new one. It isnt very disturbing however interesting is whats cause of it.

this is usual for EVERY Oled screen and is called jelly effect...
You might want to try the DC dimming option in Settings->Utilities->OnePlus Laboratory.

From what i know jelly effect appears while we scrolling some content and propably that's not what i meant in my first post. Also flicker in my case is only visible on 90hz refresh rate.
I have galaxy s7e as a second phone and that effect doesn't happen there.
