Dc dimming by App? - Huawei P30 Pro Questions & Answers

Hi,
I want to know. May I use an app to use dc dimming?
Thanks.

well you might not need an app - https://www.gsmarena.com/huawei_p30_and_p30_pro_update_enables_dc_dimming-news-37309.php
DC dimming seems to be coming as an option in the next update

what the hell is dc dimming anyway, I can not understand the explanation I found on the net..

The linked article gives a pretty good explanation, of the difference between the current PWM method versus DC method.
Bottom line: DC method generates less screen flickering when running at a lower brightness setting.

[Q] Please help- Screen TOO bright even at lowest setting! :( any remedy?

Hello everyone
I just got the Samsung I9000 Galaxy S yesterday and my worst nightmare has come true. I have sensitive eyes and keep brightness on all my equipment at the lowest level. I had asked someone before buying this phone and he told that it is manageable but now I find out that the screen is way toooo bright even at the lowest setting!
It strains the eyes + drains the battery.
Suppose we are not connected to internet through any source. Then if we refresh any widget we get the error "Please check your network access" and the screen goes dull in background. Now thats the perfect setting I would like for the phone.
Any idea how we can reduce the brightness even further through Mod or through factory settings or somehow?
I would really appreciate any help on this one.
Regards.

Bright on 35% level is correct.

Try fiddling with your phone in the morning, just as you've woken up. It works as a nice wake upper though. .
Android default min brightness is 8% (even though it reads 0%).
Two apps that give you less than 8%, both goes to 0% :
- Brightness Level by CurveFish
- Dimmer (Night Mode) by geekyouup
Also, look into changing your background color to black, it'll save you battery and be easier on your eyes. Lastly, the browser has its own brightness setting, found by hitting menu > settings.
Alternatively, only use under direct sunlight.

Thanks. I would try the dimmer and see if 0% helps somewhat though I have read that its only marginally better.
I am hoping that there should be a way to reduce it somehow since it gets reduced when we see some error just like I mentioned in 1st post.
I agree even at the lowest level its way to bright.
I have the curvefish brightness app, but even set to 0 its too bright for use in the darkness.

I've actually written that it's only a marginal improvement, but I omitted that opinion here since I think my opinion is less applicable to someone with sensitive eyes. You might perceive a 3x decrease than what I did, not sure if that'd still be enough.
Again, I think changing to a dark background will get you more mileage, if you haven't already done so.

Currently I am using a relatively black background but when surfing most webpages have white background and that really is painful! I guess I may have to look for some tinted screen protector!
i know this may sound strange, but If I wear my sunglasses at night while browsing it works quite well
You can also use tasker for lower brightness levels..
Sunglasses.

I am currently using "Dimmer". It takes the brightness levels from 30% (Though in settings it show minimum only) to 10%. I have also tried "Quick settings" so I guess tasker would perform the same function.
When we have locked our screen and we have to unlock we have to slide the screen. When we do that it seems like we have to slide a transparent layer of glass which is quite dark.
Now I am no developer but is it technically possible to create an app which is like a layer of tinted glass on screen so that it dims the screen further?
Regards
I haven't tried the dimmer apps yet but I DO agree that I miss my iPhone which can be set to a much lower brightness level for better privacy, night vision, "before sleep reading".
but I think it has something to do with the display technology. The OLED for Samsung may not permit such low levels or so. I am not sure...

At first even I thought that and I was worried about that. But there are some times for example when you get some error on the screen the major part of screen goes quite dull so it is indeed possible to do that technically I guess just that it cant be done through brightness.
I am baffled why did the Samsung/Android guys set lower level of brightness as option also. It would have cost them nothing and would have saved us a lot of strain and battery life.
PS: Is this the issue with Android or Samsung?
To someone with a bit more knowledge: how hard would this be to do something about? We all know the screen dims to a level that's not for the moment available to manually set some time before it shuts off, so it's got to be a way.
The screen is just too bright for me at the lowest setting - meaning it hurts me eyes (some pity here Samsung) and consuming a lot more battery than it needs to.
+1 for the app that will do this
got me new galaxy s for a couple of weeks now.. but really miss my old htc hd... the minimum backlight setting was awesome for nighttime reading/browsing.
switching on the sammy in bed in the week hours of the night makes my eyes burn! hehe.
an app to force lower or add a filter over the entire screen would be awesome!
samsung galaxy s has a SUPER AMOLED display which is why its bright even at lowest level.

Well I dont know for sure. The device has been working same since the 1st day. I guess its just that the brightness is too much for me. As far as the screen is concerned I didnt notice anything significant but any easy way to check about the problem?

[Q] Get lower brightness of NC screen?

Hello,
Even at the lowest brightness, the NC screen is still too bright at night. Is it possible to get a lower brightness level on a rooted NC?
Thanks,
Anat
If you are Rooted and have Quick Settings installed, try to adjust the Brightness from the app.
It also has an Auto Adjust brightness setting, if the Nook has a light sensor it will most probably work.

Automatic brightness doesn't work when set. Screen will go to dim and won't change. I believe the light sensor is to the left of the N button. At least I think it's a sensor.
Could anyone with a rooted NC try AdjBrightness (http://forum.xda-developers.com/showthread.php?t=731032) and see if the brighness can be set lower than the factory mininum level?
Thank you very much.
Yep adjbrightness works great with the NC. Great find!

looks darker than stock to me.... enough to where it might be too dark in any lighted setting.. It sounds like that's what your looking for..
wow thats some serious hackage any value below 5 causes the screen to flicker for me, but with brighness of 5 i can barley see it in a pitch black room!
What value is approximately the factory minimum level? The software seems to be a solution for me Thanks.

A fantastic solution - thanks!
Wow! great find
definitely gonna try this out when I get the chance
I would like to state that this app still works wonderfully for CM7. Its great because I find the stock brightness to be way to high when it is at its lowest setting.

[solved] Adaptive brightness broken in pie

Does anyone else have this issue? Every time you lock/unlock the brightness auto adjusts again (and it adjusts pretty low)
So even if I manually set it to 100% and lock/unlock it will be down to 25% again. Doesn't seem like it's learning at all

Seems like it takes a lot of time to learn. I don't use it anyway I prefer having control on it

Seems like a bug honestly, because it goes TOO LOW. I tried to lock the device several times to see if the "learning" of the slider improves, but it still goes back to the same spot... I'm gonna keep it deactivated until they fix it.
Android Pie has AI in basically everything and it learns for you, just keep adjusting the brightness manually and in a few days it'll know how you like your brightness and adjust it for you.
I care about to go low! And now I can't go below 19% with Adaptive ON, it's to high for a dark room.

Actually I've been reading similar things about this on the pixel so it might just be the way it is. Might take long for it to learn. I read someone say it's always fun when he first unlocks it
And I found this link of people claiming it is like this the first few days until you train it better

Yeah it could be the new implementation of the AI, I'm gonna use it for a few days to see if it gets better
This has started happening to me since yesterday. I've been using Pie for a month now (December update). What I've noticed is that it goes down to about 25% every time I cover the brightness sensor with my finger (usually when watching YT) and it stays there no matter what. It's pretty annoying having to always adjust it like that. Using "Sensors Monitor" app I see that the sensor is working correctly so it's a software "feature".
Any suggestions on how to mitigate it besides using "Velis Auto Brightness" app?
How do we know its 'AI'? Has it 'adapted' for anyone till now? That brings us tk the question, what was wrong with Auto Brightness in Oreo? Just because there's piece of code that's new, doesn't mean its versatile.

Yeah, and some of us would be fixing what was intentionally broke. Interesting, what would Android be without the community working as the underdog?

Auto brightness

How's your auto brightness working? If I set mine to auto it just dumb. In a dark room the screen just gets dark. I mean, it's always in a lower brightness setting.
Can't use it in auto.

Same. I never usually like autobrigtness for the reasons you mention. I remember an app called Lux which was great at the time, as you could customise the brightness levels per lighting environment and was much better at managing brightness automatically.
For now though I generally keep my brightness around 20-30% indoors, pretty much 100% daytime outdoors (or ill put autobrigtness on then) and around 0-10% in the dark/bedtime - sometimes with reading mode on too
Surely it's something to be fixed... Unusable for now

Walking into bright sunshine, brightness level

Hi
Does anybody else have this problem? You're in a dark room with your brightness on low. Then you step outside into bright sunshine and you can't see your screen. You can't even tell of you've successfully unlocked your phone, or swiped down, or where thr brightness adjuster is. It's quite frustrating. I've searched for an app that automatically makes the phone go to max brightness upon opening it. I cant find one. My plan was to use the OnePlus gestures functionality to make it so that when I draw an M, the app will open and set max brightness.
However, I am not sure if this will work as the phone will need to be locked and sleeping for the gesture to work I presume.
I've looked into Automate but it has gestures for the fingerprint sensor.
I have a rooted OnePlus 5 with OxygenOS Oreo 8.1. Any ideas? Thanks in advance.

Try this one, you can adjust the trigger for the task according to your needs. I use the shake-gesture and it works flawlessly.
