MeMo Pad ME572c fluctuating brightness

Just picked up an ME572c and I'm very impressed for the price. However I have noticed the screen brightness levels keep fluctuating as if the light sensor is constantly detecting different light levels.
Has anyone else experienced this?

Hi,
i notice this too, but that can be related to the power saving mode. Plz turn it off and check the settings in detail. Maybe that helps.
Further inside the developer options there is another option to configure the auto brightness.
You can change the behaviour from dynamic to immediately or slow mode and active an onscreen lux, gain and brightness value display.
Btw i am not satisfied with the auto control, as for my taste the brightness is still too low in a less lighted room. Sensor is reporting 0 lux already with a brightness of 14 which would be ok for a really dark room & night but not at daytime.
What is your experience?

I tried playing with power saving mode and the auto brightness controls in developer options. While I could reduce the fluctuations, I could eliminate them completely. Unfortunately I found it too distracting and returned the device earlier today. It's a shame as everything else was quite impressive for the money.

I also found the fluctuations annoying, my solution was to turn the auto-brightness off. Honestly I dislike auto-brightness on any device, it was also one of the first things I turned off on my laptop.

I am using Lux app now and raised minimum brightness at 0 lux. Thats ok for me now.

Just bumping this to confirm this works and so that others can see. I used Developer options as well (before I found this post) and noticed the instant setting works best.

One more setting to also double check... Make sure that in developer options under auto brightness that you disable allow change gain...
Even with everything disabled it appears as if something still is changing the display. I particularly see it with something like a reddit browser when I'm viewing pictures. You click the pic, it loads and displays and then 1-2 seconds later the display adjusts based upon what is being displayed. Depending upon the picture it can be pretty annoying. I may have to root and start poking around to find out what is causing this.

with the lollipop update this issue is fixed for me.

Is lollipop really solve the problem?

Hello!
Im on lollipop, but the problem you had, still occur at me.
Did you noticed this problem, since you on lollipop?
I have the same problem. When i read, or browsing, the brightness changes in 2-3 steps.

Dim brightness + Mic sensibility + other infos

Hi there!
I am a new user, and I've got some questions:
1) Is there any way to change dimmed mode brightness live from the watch?
2) Is it normal that alarms don't work during Theater mode?
3) Is there any way to reduce microphone sensibility? I find it pretty unusable when in my car because of the ambient noise (it just keeps listening as there are other sounds)
Thank you very much in advance!

Hi, let's se what i can help u with
1) From the watch you can download the swapps true dark or something like that which is a kind of screen filter reducing the brightness on both dimmed and live mode.
2)yeah, that's how its supposed to work
3) mmmh same thing here, since we use it on the wrist which normally is used to drive the car xD idk of anything to reduce the sensibility, hope someone here comes out with a solution

1) I've found the app, it works, but still have to figure out HOW does it work :silly:
I don't understand what the light bulb stands for and why it becomes full or empty when I choose the settings (I suppose that the bulb "on" means the higher lvl of brightness, bulb "off" the lower one, but can't really understand how to set this properly - but it works somehow, so this doesn't matter too much)
2) Ok
3) I think this is something kernel/rom related, some value to change, like the vibration one (by the way I MUST apply the vibration mod, because I don't wake up with the normal intensity)
Thank you again for your help!

You're welcome!
In swapps the bulb should work the exact opposite way you guessed xD i mean full bulb means the "dark mod" is on so you should see the screen darker (select the intensity of this "dark filter" below on the grey-scale thingy, on watch app). When you tap on the bulb it becomes empty and the filter is deactivated so your screen turns back into default brightness.

Brightness Management: What's the best way?

I don't know if anyone else feels this way, but I tend to think that the auto brightness setting on stock lollipop is WAY too bright, and, while of course it shows off the screen, it wastes battery life.
I can turn on power saving mode to try and dim the screen to some extent. I've also given Lux a try, but it didn't really seem to do much...
Does anyone have an idea for auto brightness which works similarly to how CM12.1 does it on this phone? Where you can set how bright you want it to be, but it still compensates for ambient light?
Thanks!

I like screen filter. It's very simple and you can pick which percentage you want. I've gotten it lower than stock. I'd recommend giving it a try. Couldn't hurt.
Not sure about the ambient light bit, last time I used it was on my note 2. It may be available.

There's a setting for ambient light too.

Brightness, no more Auto

I haven't used Lollipop at all yet, just picked up the N6 yesterday. Autobrightness is gone, now they want you to slide around the bar to however you want it with adaptive brightness? now how does this work? lets say I set it to full brightness and enable adaptive, itll use anywhere from 0-100%? is the bar just to cap it somewhere so it doesn't exceed? if so what do you have yours set to? Whats a good way to do this all and avoid image burn, ha. which I Heard is kinda a big deal

That's exactly how adaptive brightness works. I have my slider set around 25-30%. I change it if I need more outdoors.

This is how I understand it and how I believe it works.
With adaptive brightness OFF, you have your brightness slider in the pulldown that goes from ~5% to 100%. This slider set value will remain until you manually change it. Easy enough.
With adaptive brightness ON, you have that same slider in the pulldown that goes from 0% to 100%. Your brightness will change automagically dependent upon ambient light. Look at it as "minimum automated brightness level"
Some tips. Your screen can get darker with adaptive ON and slider all the way down than with adaptive OFF and slider all the way down. Unless in very bright ambient light, your screen can get brighter with adaptive OFF and slider all the way up. Hence, in full sunlight, the peak brightness of the screen is the same with adaptive either ON or OFF and slider all the way up.
I admit its confusing and it frustrated me at first, but I think its excellent and works much better than auto brightness on any other phone or older android OS I've ever used.
As far as burn in (or the more often occurring image retention), well its an amoled, it's susceptible. Just be smart about it and don't display the same static image/s for hours on end.

I used to think that but after testing, it seems more complicated than that.. It also looks like to may apply a "range" using the slider, but its more complicated than that too.
The closest thing I can think of is it increases the sensitivity or effectiveness of the adaptive brightness.
Have a look at our tests here, maybe you can do some testing and develop our initial findings.

I'd love to set it to an exact percentage cuz I'm ocd that's why I hate the slider. How do I really know it's at 25%

Yeah but once you know 25% is 63.75 on the brightness scale and brightness can only register full numbers, you're day is blown anyway.

I think you nailed it better than I did in my explanation with your statement "increases the sensitivity or effectiveness of the adaptive brightness".
My explanation was as simple as I could write it. I especially like the word "range". Thanks for the link I'll check it out :thumbup:

So is it true if its set half way if the sun hits it that it can use 100%. What do you guys have it set to? I liked the auto brightness ?

Yes if the sun, or even very bright ambient light hits the sensor, the display will go to 100% full brightness with adaptive ON. At least it does with mine (to my aging eyes). I leave mine at about 50% adaptive ON. I like it too

I use manual.brightness.

For everyone testing display settings have a look at 'Pixel battery saver' in the play store.
The app switches patterns of pixels off and saves energy.
Note.
Because this kind of apps are switching pixels off, it is possible that ticking buttons will not work.
But there is an option to turn it off, and several levels of settings.

The note 8 sun mode kicks in even with auto brightness turned off

Ok guys so I need to know if there is a sensor issue with my phone .I don't use auto brightness no more because if you go in the sun the brightness overrides itself to brighter than max brightness and it is the reason why I've had burn in 4 times so far and had to get the screen replaced. But I've also noticed that with auto brightness off but you have the brightness maxed out and go in the sun or shine an led torch at the sensor the screen will kick up to override max brightness sun mode out like when using auto brightness. Is this normal behaviour. Can anyone test this fpr me please .only 6 months left of warranty left
So if this is a feature its stupid ,and make sure you never put your phone on max brightness in manual or autobrightness if out side and it's sunny as it will kick in and cause screen burn .
I've factory reset it and cleared cashe still the screen in manual mode if maxed out in the sun with the brightness maxed out will auto ride to super max brightness mode .im on the oreo uk fm
Phone is uk unlocked note 8.

Anyone? I see lots of views no replys I'm sure everyone that view this thread owns a note 8?

OK lol thanks for the great respone guys smh this place sucks :good:

No, this place does not , if you do not get any response , it means nobody has something useful to share, beeing rude will gain you a ban

Maybe your the only person that has this error, so no one has any advice to give other than to factory reset (which you all ready done).
Most people has moved on to other phones. So you'll have to be patient. I say is take it to the Samsung store and see if it is covered under warranty.

I'm not the only person all note 8s do this i think but nobody in this thread owns a note 8 or 9 other than me because they both do it. On both my phones.its a terrible feature as it will cause burn in.if you want to be able to see the screen outside in the sun

So i've been using auto brightness for 2 years, i don't have any burned screen. Last week I've been using phone on sun, taking a lot of pictures (brightness set to auto, on camera app its option to set it to max bright) and still no burnout. I think you should say your problem to guy who will accept your warranty next time

Well this is good to know just went to the sammy service centre and tested the phones they had there with my led torch and they all do it including the s9 plus .so it maybe always was like that or it's been added into a fw.

I will add that friend have a s8, his screen is good. Also another friend had note 8 and now note 9, always autobrightness on, no problems so far.

I have a little experiment
1st, I set auto brightness on, turn on a torch on the sensor, brightness go to max, then turn it off, and brightness go to middle (room light on)
2nd, set the auto brightness off, slide the brightness to minimum, turn on the torch to sensor, and brightness remain to minimum, nothing change
So I assume maybe it's a software feature I don't have, you can check with your friend running the same firmware, or you can check using *#0*# on keypad, click on sensor, look for light sensor, and do a simple test, see how much lux you have when you're on direct sunlight, or in a room, then you can flip your phone down / reverse the light source, the lux sensor must be read it on continuous count, as you flip your phone, the number will get decrease
I hope you understand what I am saying, because English is not my native language

You did the test wrong friend you need to turn off auto brightness and slide the brightness slider to max brightness it must be fully maxed .then shine led torch at the sensor then the brightness overide kicks in and goes even brighter just like In auto brightness mode.but if the slide is not fully maxed it won't do it

Interesting you mentioned all devices do this before you went to the service centre and confirmed it. That admission renders your entire post pointless. If all the devices does this, it means it's not a fault on your sensors or anything on your side, and it means it's indeed just a feature.

I said imo that all devices have this issue. Because bothe my note 8 amd 9 have the same issue .and i found a thread on reddid where 2 others also had the same issue.its not a feature because it can damage the screen it must be a software bug that Sammy need to fix

Ah I see, after doing that, I found out that the screen goes brighter and the colors seem to be fade out
Maybe it will help us to watch better when we got under direct sunlight (I think it's not a bug)
But in real life usage, I have my adaptive brightness turn on, then when I think it's too much bright at the moment, I will manually adjust it to my desire brightness
So that the system will learn the pattern and will apply automatically next time I had the same condition

Doesn't do that with mine and I live in Hong Kong.
