The ChameleonOS team is proud to present to you our latest addition to the growing list of features. Please give a warm welcome to the new active display feature. With active display your device can turn on when new notifications arrive and display that information to you on the screen. There is no need to turn your device on every time you hear that distinctive notification sound. Your notifications are right where you need them without all the clutter and free from other distractions. If your device has a proximity sensor, which most touch screen phones have, you are in luck. Active display will not turn on if it detects something close to this sensor. So if you have your phone stashed away in your pocket or bag, don't worry, it won't turn the display on and waste your battery. And as an added bonus we've included an option to turn on pocket mode. When this is enabled active display will turn on your screen and display your current notifications instantly, provided you have any pending notifications.
Features
Instantly turns the device screen on and displays notifications as they arrive
Up to 8 notifications displayed in a horizontal strip that can be viewed by touching the notification icon
Short notification description can be displayed around the outside of the center ring
Touch the center ring notification to view the full notification
Unlock the device, open the app for the current notification or dismiss the current notification
Set a re-display time to have active display remind you of your pending notifications
Adjustable brightness level for when active display turns the screen on
Pocket mode which allows active display to turn on once you remove the device from your pocket or bag
Video Demonstration
* Active display will be merged into our github repos shortly and will be included in the upcoming nightly builds thereafter.

Now for the important stuff that developers may be interested in. Since ChameleonOS is an open source project this feature is available for other developers to pick and incorporate into other ROMs. If you want to incorporate this you'll need to grab a few commits from our frameworks base and Settings projects.
From android_frameworks_base you'll want to pick the following commits [4.3]:
0e846d1a210f9ac937689ac6fa6052decd6090bd

*Note: ChameleonOS started out by using CyanogenMod as a base so some dependencies may exist which would need to be resolved when incorporating this into other ROMs. Feel free to contact me if you encounter any problems and you can't figure out the resolution.
**UPDATE**
For those that are using a 4.3 or 4.4 based ROM that does not have Active Display integrated, I've managed to develop a stand alone application that adds the functionality of Active Display. There is an ad supported version as well as a paid version for those that like to support independent developers.

Is there a pulse setting? Or is that the re-display option?

I guess you could consider the re-display option as being similar to pulse for the LED. Active display will turn on and show pending notifications at the interval specified by the user.

I guess without the Moto X dedicated CPU a pulse option would kill the battery? If you miss the notification, you can't really tell that you've gotten one.

The minimum setting is 1 minute so you could set it to that. Because it turns the display on momentarily to display the notifications, there will be some power consumption because of this. There are several different values the user can set this to and in a future release I'll have it so the user can set their own time instead of being confined to the discrete values that are available in the current implementation.

May be it is not only using call sensors but as well acclerometer.. this way it might not turn ON.. But wondering about battery drain..

So, do we just flash this the usual way or are there special instructions on how to properly do this??
Thanks in advance, this Rom looks AWESOME!!! Can't wait to flash it on my SGS3

About pocket mode, it says it will turn on active display when out of the pocket. And so this means the proximity sensor will be on all the time after receiving a notification?

You can't make a chane to the source code with a flashable zip. THat's more work on someone who wants to do that, or a device maintainer could just cherry-pick the commits he's highlited which would be easier imo.

yes, pocket mode will enable proximity sensor when screen is off. Waving your hand over the device will also turn on the screen if there is a notification waiting as well, perfect for when my phone is on my desk.

And so this will kill the battery slowly until the user puts the phone out of the pocket.

It's been quite reliable for me. It uses the device's proximity sensor to determine if it should show the active display by listening for when the sensor goes from something being near to something being far (typically >5cm). The motivation behind adding this was because when I take my phone out of my pocket it is usually to check something. Having it turn on and display my notifications the moment I take it out just made sense to me. If you don't have any notifications then it's not going to turn on. I also use this to look at my notifications when my device is sitting on my desk. I can wave my hand over the screen and it turns on. It is an option so people can enable and disable it as they see fit.

tsukot said:

No it won't. Proximity sensors are interrupt based meaning they only update when the state changes from near->far or far->near. All the proximity sensors I've worked with thus far only provide two different values, one representing near and one representing far. So if the device is in your pocket, the sensor code is not going to be called until you the device. It's not like an accelerometer where values are always changing and thus code is always running.

Sunlight mode coming soon
I wanted to share a new feature coming to this implementation of active display. Some, if not all, displays are hard to see in direct sunlight so I wanted to see what I could do to make active display stand out a bit when staring at it when the sun is beating down on my display. I found that if I invert the colors, the items and text on active display are much easier to make out. If your device has a light sensor, and this mode is enabled in the settings, active display will invert the colors when it detects a bright light source. Bright in this case is greater than 8000 lumens.
For those worried about the sensor always polling, don't worry. The sensor is only being used while active display is on and showing content. Once the screen turns off or you unlock the sesnor is no longer being used.

[APP][4.1+] Save your battery power with Pixel Battery Saver (Pixel Overlay App)

Hi!
At the beggining - I'm sorry if you won't understand something. English isn't my main language, I still learn.
In some smartphones with AMOLED screen (such as Samsung Galaxy S4) black pixel = turned off pixel.
I've always been irritated because of the fact that our batteries aren't too great, but phone producers still produce their phones with hiper-resolution, which practically we cannot even see.
I have invented something, that later I turned to real app.
I call it Pixel Battery Saver, because it displays some kind of totally black mesh on the screen (you can change its density), so at least half of the pixels (or more) are turned off (so the screen consumes less energy!), while you are still able to read anything on your screen.
If you still don't understand, just take a look at the screenshots.

I've already created this app.
You may download and test it for free,
but if you really appreciate my work - I would be grateful for every donation (every single dollar would be helpful).
Let me know if you found any annoying bug or misspelling. This is my very first app - I still learn
FAQ:
What do I need this for?
- Imagine this situation - your battery level is really low, but you have to search for something important on the Internet. Making the brightness lower often isn't enough. That's when you would need my app - to turn off some count of pixels.
There are lots of apps that dim the screen...?
- This app works different. It doesn't overlay your screen with transparent image (but there is such option in premium version if you need it too). It overlays your screen with totally black screen, which makes some count of pixels off, to prevent them from consuming battery.
Do I really need AMOLED screen?
- The best results you can get right with AMOLED screen, where black pixel means turned off pixel. However, even in other type screens black pixels are saving some battery, so it's just worth to check.
In battery stats I can see that this app consumes a lot of energy. Why?
- Don't look at the stats, look at the real battery consumption. Probably, Android Battery Stats app "thinks", that this app display an image on the screen all the time, because of what it shows an information about consuming energy. In fact, this app turns OFF the pixels (in AMOLED screens with this function), so it SAVES that energy, not consumes.
When the mesh is on, I am unable to install apps (Install button is disabled). WTH?
- That's because of the Android Security. In premium version of Pixel Battery Saver I added an option to bypass this protection. In this free version you can simply turn off the app (by clicking "Turn off" button in Settings window) before installing any app and then turn on it again.
Density of the mesh that I recommend is "High".
Changelog in post #2.
Download: Google Play

Always use the latest version with fixed bugs and new options.
[CHANGELOG]
v1.3 (coming next month):
- new option to automatically start service at specific battery level
- hidden notification icon
- option to detect package installer to prevent its bug (stops mesh activity when you're installing new app and starts it again when it's done)
- new option to dim the screen (useful at night)
- small fixes
v1.2.1:
- fixed doubled mesh after reboot (black screen)
- fixed unnecessary scrolling to the bottom ad
v1.2:
- quickly show/hide the mesh with notification action
- Ads. Sorry =)
v1.1.1:
- shortcut to the donation page
v1.1:
- new option to automatically start service on boot
- small bugfixes
[TO DO]
- Widget
- Overlay bottom navigation bar too
[KNOWN BUGS]
- I can't install any app (unable to tap Install button)
> This bug is fixed in version 1.3 (added new option to prevent this)
- The bottom navigation bar (with back, home and recent apps buttons) isn't overlayed
> I know about this, I will fix it in the future

There are a couple of issues with the concept as you've outlined it.
1) Turning off 50% of the screen you make small text unreadable. Even in your example the not so tiny temperature values are illegible.
2) While this would definitely conserve power in terms of physically lighting the screen, it might not be by as much as you'd think. The screen has multiple power sucking components. The first is the light producing LED's. Turning half of them off saves half the power. Simple math
. But the GPU that processes the screen imaging still runs at full speed even if the screen is blank. While the LED pixels aren't working, the GPU is still working to render a black image. So turning off half the pixels doesn't reduce the power draw required to run the entire display to 50% in total.
3) The app that overlays the black mesh will require the GPU to work overtime. It's got to render the image that's supposed to be in the screen plus it's got to render the black mesh over the native image. That could potentially use up more energy rendering the black than the black saves by not lighting the pixels.
4) The already built in option is to just turn the screen brightness down 50%. It accomplishes the same goal, requires no additional image rendering, and preserves the original image design without loss.

1) Why do you think so? As you can see on my image, it doesn't make the text unreadable (if the "mesh" is pixel-by-pixel)
2) Right, but everyone know that black-layout apps are muc better for our battery than colorful or white, right because black screen isn't that "hungry" of power
3) Ok, but there are lots of apps that creates a full-screen black (transparent) overlay to make the screen more "shade" (dim?) to save the power. It works, even thou all the thing you described in #3
4) Oh, right, but when my energy power is really low, I turn the screen brightness to the lowest level, but it still consumes a LOT of energy.
Anyway! This discussion isn't even important, maybe we should just CHECK if this may work, or if not?
But, as I said, I am just asking someone to create a simple app like this.
Thanks anyway for reply.

Really? No one?

it's not worth in my opinion, while rendering half of the screen black would help save some battery, the saving wouldn't be so great, yes the screen is what burns the most battery on android but, its not just having it on, its having the phone out of deep sleep, having the touch sensor activated and registering touches, etc, not to mention it would just kill the great viewing experience that the phone offers.

Though when we are using our phones it has to render the whole screen anyway, so I think rendering a half of it would be better?
I am not thinking about this app making our screen always on. I just mean to display this mesh when we are using our phones and the battery level is low.
And, of course, it would kill the viewing experience, but when your battery level is 5% and you have to do some important research on the internet - you don't care about the viewing experience.
If you think turning the pixels on is not the thing that consumes the most of the battery, then turn the brightness to the highest level and then to the lowest and see how much it consumes... (changing the brightness doesn't change anything with the touch sensor and other thing you described though)
I thought my idea is really simple to develop for any Android developer and to see if it really works...

I think that if you do some comprehensive tests, you could bring some attention.
Create one image with this pattern, put on your phone and open it with any image viewer, put the bright on max. Let it run for some time.... Measure how much battery was sucked.... Test again with the same image, but without the pattern, do some statistics with the results.
Are you rooted? You could invert screen color or make it grayscale.

That's exactly what I was thinking about. I will do this tomorrow.

I'll post my quick opinion. It really depends on how the phone handles the screen, but my experience is from my old Galaxy S2 with NoLED running over night. I think NoLED program was essentially accomplishing what you are proposing (i.e. rest of screen is "off" or black) and on portion of the screen is on for the LED to hop around. However, even though the screen was black the screen was still draining at a quite high rate (~6%/hr on average). The screen needs to be "off" not just black in order to save more power.
But having stated the above, I am looking forward to your test results to compare and determine if it can save more battery.

Thanks for your opinion, but the screen in s2 is way different than on s4. The screen in s2 doesn't turn off the black pixels. The one in s4 does.
II am looking forward to do this test tomorrow

I think this would be like a filter app, such as the found in Play Store.

Exactly. I was talking about it but I forgot the name. I next hour I will do some tests.

Ok, thread can be closed - I've created this app by my own. I mean, I used many of tutorials and examples, and finally got it. Thanks anyway.

Could you share your findings?

This would be pretty hard, as I have read dozens of sites and forums to understand everything. There wasn't any quick or simple solution.

Did it work and save as much battery as you expected?

Ok. I think it really works, but I'm still not sure. Give me few days to share the alpha version of my app (I just want to add some extra functions).
By the way, does anyone know where should I look for a list of phones with screens like in S4? I mean where the black pixel means it's off.

Here's a list of some recent ones. Pretty sure the Moto X has one as well.

Screen Issue?

When watching movies or playing games, the colour and brightness changes. It looks very bland and dead, lifeless.
It looks too bright, dull with weak colour. Sometimes brightness will change higher or lower when using the device.
Auto brightness is disabled of course. Anything I can check to try and see why my screen is acting and appearing so strange?
I'm running stock Oreo 8. Colour calibration is near the top, 12:00.

It's a very strange issue, unsure if normal or not.
However, as you said, it happens the most when you are outdoors and it's bright, the screen appears to go very bright and colours are washed out.
After playing a game, I can see the brightness changing automatically and when quitting the application, the screen dimmed by itself. Very noticeable, WTF?
I've never seen such an problem with any other phone.
Even had a recent Huawei Honor 7X, no such issue with the screen.

I think Oreo is bugged, like Asphalt 8 plays slower than on nougat, freezes and chrashes my phone, like literally screen flicker and reboots, might just be another bug or something

Thanks for the tip, I've now disabled that option from the ''developer menu'' and will do some testing. I shall report back shortly! After looking through some other forums not only should it prevent the screen from dimming but also increase maximum contrast which is a bonus!

Still the same. Turning ''increase readability'' on/off makes no difference. Brightness still increasing/decreasing on it's own.
Also, when watching videos, colours are weak/washed out and appear too bright.
Probably a software issue? Unfortunately, when previously on Nougat I did not test this as I immediately flashed Oreo the day I received the phone. Oreo bug perhaps.

I will give this a try. As of now, with readability disabled, the black levels/contrast look higher.
However, it is a shame. Unsure if it's a fault or not, but the screen looks pretty good when playing games or browsing through images but when watching videos/media, colours/contrast are washed out and it looks really bad, here is an example:

EXACTLY!!! It's a shame because when browsing through images, gaming or even browsing the net, the screen looks fantastic.
However, with movies, colours are washed out and the picture looks like high contrast. Never seen this problem before.
I wish there was a fix.

After doing some basic testing, I found a way to fix the horrible looking picture when watching movies, it does not work with YouTube or Netflix, but with regular video/movie players.
For example, in MXPlayer Pro, In the settings/tools menu, go to decoder and select ''software decoder'' . When selecting HW or HW+ the screen flickers and colours are washed out and contrast/brightness is far too high.
Can others please test this on high quality MKV or MP4 movie files?

Another update, dunno how I forgot to test the difference but boy was I surprised.
Check out some high quality YouTube videos. Watch these videos on the YouTube App followed by the very same videos on YouTube in the internet browser.
For me there is a BIG BIG difference, unsure if I'm the only one but please test this. Video's look $hit on the YouTube app, too bright and dead/colourless, horrible and dull looking.
However, the very same videos seen in YouTube in my Chrome browser look simply stunning. Amazing accurate colours and deep blacks, just how they are supposed to look.
Later in the evening I will try to compare some videos myself on both the YouTube app and in the browser.
Question is, why am I getting these issues? I would of thought YouTube, whether viewed in the App or in the browser would be the same. Is this some software fault??
Please test the above and share your results.

In the YouTube app type pure black and watch the first video. When the phone is upright it looks pure black no problems. But then watch the same video with the phone horizontal and the black totally changes. Do you think the problem you're having could be related to this bug. Huawei should fix this.

I have a different problem. I see some sort of "burn in". For example when im using one app and switch to another one i can still see some parts of first one (menus etc). It's very noticable in dark room at 20% brightness. Since i'm playing CSR2 very actively this Audi logo makes me crazy

I also experience screen burn. But it fades away after a while.

Galaxy A51 no blue light filter on lock screen! Why?!

Note: The following post was posted on Samsung Members: I thought I'd post it on here to raise awareness: and to get help.
Recently brought a Samsung Galaxy A51 for a family member, and upon setting the fingerprint and activating the blue light filter: I realised everytime I'm on the lock screen, there's no blue light filter! Upon unlocking, the filter is applied to the rest of the phone. I read on the Samsung forum when someone asked why, that it's like that due to the fingerprint. So why can't the rest of the screen, apart from the fingerprint area, have blue light filter?! Am I expected to burn my eyes whilst trying to look at the time in the middle of the night?! I'm sure with Amoled panels, that each pixel can be controlled, so why hasn't this been applied? Samsung needs to step up their software game as a simple error like this gives a terrible experience. Not the first time something like this occured on a Samsung device.*Furthermore, I tried a third party blue light filter: Twilight which worked fine with the fingerprint. Rather use the in built one as it's lots better.
I'd appreciate any help, thanks!

You can set a Bixby routine to lower the brightness and turn on blue light filter at certain time.
I really like the lockscreen with full brightness, to enjoy the beautiful images of the dynamic wallpapers.

Thanks for the suggestion. I still think samsung should e automatically implement something to make the lock-screen, eye-frienly at night time. As the screen is really nice, but it hurts your eyes at night. They really,
really need to fix the software as there are a few issues: one of which is that it's buggy.

AMOLED burn-in solution and question

OLED displays gets burn-in almost exclusively in places where there are a lot of elements that stay completely white all the time. Most notoriously, status bar and navbar. For some people who text a lot, I have seen burn-in for the call and video call buttons, as well as individual keyboard letters.
My question is, is there an app, or a theming engine to be precise, that would allow the user to set a time interval, during which those high persistence elements of the picture could be dimmed over time? For example, user unlocks the phone and starts typing a message - navbar, statusbar, keyboard letters are all 100% white. They remain white, then after 60 seconds they start to dim, and after 120 seconds they are at 30% brightness. So when you're having long texting sessions, keys would be dim enough so you can make them out, but since they are not leaving your muscle memory you can type just as well as if it was at 100% brightness - but you save a lot of energy and thus substantially reduce the potential for burn-in. And if you're outdoors and can't make out what the time is after those 180 seconds, you gently pull down the notification bar and it resets to 100%. Something like that.
I can't be the first person to think of this. Moreover, I think AOSP devs realized this at around version 9 and dropped the overall brightness of the status/navbar to 80%, but it remains like that the whole time. What I am proposing would be infinitely more efficient. Anyone here knows something that's able to do that?

Avoid use in direct sunlight. Seconds not minutes if you do. Use manual brightness control and keep below 50%. Typically I comfortable use 30-40% indoors. Excessive brightness prematurely kills AMOLED displays needlessly. Excessive heat with the display on ie again direct sunlight should be avoided.
Use dark mode. The red pixels are longest live, blue the shortest; heavy blue or white usage will degrade the display the fastest.
Use icon packs and layouts that support pixel conservation. Rotate widgets and icons periodically.
This heavily use N10+ has over 8k hours on its display. There is no detectable fading, failed pixels, color inaccuracies, nothing; it remains perfect. It's a mirror image next to my new N10+ with less then 50 hours on it.
AMOLED displays can be very long lived. Everything on this homepage gets rotated slightly from time to time, even the page number icons ie 3 instead of 2.

I think you could look into immersive mode, It has many different names Another option talk in developer forums fr your phone , otherwise its hidden somwhere in your settings

Is there a way to prevent burn in when using the phone in a bright environment? My job requires a bright environment.

No other than the mods I already mentioned. AMOLEDs have a finite lifespan that's proportionately shorter or longer dependant on brightness level. The brightest stars burn the fastest...
All you can do in that case is use at minimum needed viewing brightness and try to use in shaded areas.
Maybe use a work phone so you don't burn up your personal phone.

I am under the impression that none of you even read what I asked in full. I asked a very precise question regarding a particular way to mitigate burn in, nothing on HOW to to mitigate it, as I hinted in the name of this thread.
1. "Avoid use in direct sunlight." Excuse me? Phones are meant to be used outdoors, and they have been since the birth of the idea of a mobile phone.
2. I don't have a Samsung phone. What I meant was something more universal, like a Magisk module, or a root theme engine.
3. With due respect sir, everything you mentioned is more of a paranoid hassle than an automated instant-fix. What I proposed, on the other hand, is.

Welcome to the planet. The more you run it in direct sunlight the higher the risks including outright failure. That sound better?
This isn't a backlight LCD* or a LED display. OLEDs are less robust than LEDs.
Due respect my mass... prudence isn't paranoia.
8+k hours here and no detectable damage of any kind.
* direct sunlight can fry LCDs too.

Dude, nobody sets their phones to sunbathe for no reason. If the situation requires me, I'm using it the open sun. That hasn't damaged any OLED screen I used in the past 10 years. You ain't gonna convince anyone to rearrange widgets every week giving a meteor strike argument, especially with that attitude. Now please, are we over useless internet forum fights? I'm not negating any technical point you made, and what you did is certainly a way to deal with the issue, but it is objectively not practical for 99% of users.
