Lux - The Original Android Auto-Brightness App
FREE OR FULL
- Since I bought the Xperia P I noticed that the battery life is a bit worse than Xperia X10 (my previous phone) and the screen was too bright for me (thats due the White Magic technology), even on 0%. So I started searching for some apps that can control the brightness very well but none of them worked as I expected to. One day I found this good app, installed it and the battery life got better also the screen got darker. I recommend this app to every Xperia P user. Here is some info about this app:
Lux isn't your ordinary brightness app. It intelligently adjusts the brightness of your display based on the environment you're in. If, for example, you step into a dimly lit room, Lux will automatically lower the brightness of your display to make it not only comfortable to read, but to also preserve battery power.
Lux provides the option to automatically adjust the backlight at fixed intervals (periodic mode), when a change in environment is detected (dynamic mode), or when the phone wakes from sleep. It's also possible to adjust the backlight manually. Simply disable automatic mode and you can use it like a traditional brightness tool!
Perhaps the best thing about Lux is that you can teach it how to behave. If the backlight is too bright or dim for your liking, simply open the provided Dashboard, adjust the brightness slider to the level you desire, then hold the link button. Lux will use this new 'link' as a reference in future.
Give it a go! I want you to test Lux for more than the 15 minute refund period offered by Google. I understand that some devices may not have the best quality light sensor, and that you may need more time to play around with settings. If you find that Lux doesn't suit you after the 15 minutes is up, you can request a refund at any time via e-mail - no questions asked.

Often at night when I use phone lowest brightness is still bright so I found apps which can dim it further but then they loose screen contrast too making it difficult to read.
Is there any app which can make night mode of selected apps (browser/gtalk/gmail/other few user selectable apps) background dark & font light / white similar to youtube app?
UC browser had this night mode earlier but latest version they have removed this feature. Ideally such app should be time sensitive & as the night time approaches it should start applying the night mode.
This is what I am looking to achieve
http://forum.xda-developers.com/showthread.php?t=990102
or
like this in reverse it would save battery specially in night.

The closet App I can think of is CF.Lumen:
http://forum.xda-developers.com/showthread.php?t=1336643
It automatically changes the screen intensity/Colours according to the time of day. Brilliant app, and had actually improved my Sleep cycle.
Note : It's a addon for Chainfire 3D pro:
http://market.android.com/details?id=eu.chainfire.cf3d.pro
But the Free version has Render effects also, which also may help:

Regards and good luck.
I looked at CF.Lumens but that does different colors in night mode not what I am looking for but thanks for finding it for me.
I wish some developers can work on this concept.
What about Lux Auto Brightness?

Same problem actually all apps adjust brightness "only" they don't adjust contrast which at low brightness is required to maintain good readability. I wish some one makes this app it should be simple to do so just by altering the color value as per user time table.
Me to .
My need is for an app or a MOD that wpuld provide me woth a button thatwould allow me tochangethecolors and cntrast and brightness of all the phone.
I will use it while using the phone in the bed.
Similar to what read view with night mode in dolphin browser.
I don't know those kind of apps but when I want to use my phone at night, I use an app called "Screen Filter".
I also use screen filter but it cannot function at low brightness of 20-30% the screen looses its contrast. The only solution to this problem is night mode which many gps app have it they reverse the diplay and increse visual contrast which helps alot in saving battery too. I hope some developer can work on this idea and make an app.
Bumping it up again after 6 months hoping some one knows any such app?
Hi,
I've had my xperia S for a couple of days now and I did not notice a change in brightness depending on the ambient light. I've checked in the screen section under setting and there is no option for auto-brightness unlike my previous android phone (Nexus 1). Does the Xperia S have an auto-brightness option?
Moreover, I'm used to using the pattern lock on my previous phone. With the Xperia S, when I enable the pattern security feature, I am also presented with the normal screen lock (lock/mute). Is there a way to disable that screen?
Thank you in advance

If I am not mistaken no SE phone has auto-brightness, reason is nowhere to be found....
The same for the lock screen, most probably the ingenuity of the SE/S engineers stopped after creating Timescape...

What about widgets? Check them (there was something like Power Widget, or Power Control, can't remember), or you could use external aplication. I think Extended Controls or Free Power Widget got something like that. It is not in Display Settings anymore.
UPDATE:
Power Control (It has Wi-Fi, BT, GPS, Sync and Brightness buttons) Brightness should have 3 settings: Max, auto and minimum.

I do use widgets to control the brightness manually (power widgets & beautiful widgets). Both control brightness and power widget even has an auto-brightness check box that has no effect what so ever.

if you want to control brightness easy way try this app:
Display Brightness
Woah, wait a minute. No auto-brightness? That can't be. The specs sure indicate there is ambient light sensor. There is indeed no "auto-brightness" box to check off, unlike with other Android devices, but I thought that this new Xperia series is supposed to work like iOS devices do. In other words, you move the slider to determine the *average* brightness of the screen, just the way an iphone or ipad does. The screen gets brighter in with more ambient light and dimmer in darkness, but the average brightness is controlled by the slider.
Most other Android devices use the slider to determine a "fixed" brightness, not an average dynamic brightness.
Are you sure the brightness doesn't change?? I find that hard to believe with an ambient light sensor on board.
The white paper says there is an ambient light sensor.
I just checked the user guide installed on my XPS. It mentioned about light sensor and brightness adjustment.

I know it has a sensor, but I could not see a difference. Even when I cover the sensor with my thumb, I could not see the same change in brightness as I am accustomed too on my nexus one.

I did not imply that there is no light sensor, just that I couldn't find the auto brighness check box and couldn't notice the change in brightness.

Thanks a lot! I've checked it and my light sensor works. The change in value seems minimal though. I will play around with the brightness slider to see if I notice it now.
Thanks again!
I've had a problem for quite some time where Google Maps on my OnePlus One displays the normal Map view in near-zero contrast (no matter the screen brightness). You simply cannot tell, looking at the screen with the human eye, the difference between roads and not-roads. In Satellite view it's fine (but of course uses much more data, memory, CPU, etc, and Satellite view is much busier on the screen, so that's not a long-term acceptable solution).
I'm running CM13 on my OnePlus One; there is no Contrast setting. (In Accessibility there are a couple of related ones, but they don't actually control contrast, and they don't solve this problem, and they're both marked experimental - may impact performance).
I found an app, Netman "Screen Adjuster", which works perfectly .. but has to be always running to hold the contrast adjusted, leaves a post in notifications (despite its option to not do so), is ad supported, etc - simply should not be necessary.
Why isn't there/ how can we add/ who do we beg/pay to add a Contrast adjustment to the normal Settings in CyanogenMod 13 ?
thanks!
Content of my post from CyanogenMod forums:
On my OnePlus One running CM13 [nightlies] - I'm not sure if this specifically started with my upgrade some months ago to CM13, or if it was this way on CM12 before also - the contrast in Google Maps is much too low. Basically it's impossible to see the difference between road and not-road in the normal Map view. If I switch it to Satellite view then everything displays fine. On some other forums I've seen similar complaints both from OnePlus users and from users of some other platforms. So it's a maps+contrast thing, not exactly specific to this model.
I've attached two screenshots and a camera photograph of the same Google Maps display:
One screenshot is of normal Map view, which viewed here displays perfectly, so it's not the actual graphic content, but how the OPO screen displays it.
The other screenshot is of Satellite view, which viewed here and with human eyeballs on the OPO's screen is fine.
The photograph is of normal Map view (I tested both with the screen brightness quite high and the also quite low, both show near zero contrast making the map view unusable to the human eye, so I'm only posting one photo here).
My guess is that either contrast or something about the graphics drivers for the OPO in CM13 are causing the valid underlying graphic bits to be displayed in very low contrast.
I'm not sure why I don't notice this in other programs, just in Google Maps.
Hm. It's definitely the OPO's Contrast setting. I found an app (which I don't like as it has to be always running to keep the contrast set properly) "Screen Adjuster" by "Netman" which makes Google Maps perfectly readable by setting Contrast to "-100" (exactly halfway between the default 0 and the maximum).
So, without using some dodgy app, how to control Contrast on OPO or more generally in CM13?
thank you.

Photo of Satellite view - looks fine
Screenshot of Map view (exactly the same thing in the first photograph) - displays fine on YOUR screen which has proper contrast, just not on a (my?) OPO:
Try to change the color temperature. It might do the trick. Settings>Screen>Color temperature
Now, that's interesting.
On my OPO with CM13 within Settings -> Display & lights -> LIVEDISPLAY, I had Display mode set to Outdoor (which seems to boost display brightness and whiteness, though in no place does it speak of contrast).
It has Color Temperature (which did indeed help .. at the expense of some need-to-get-used-to-that color variations; I've re-set those to the defaults of 6500K day and 4800K night), color calibration (100% for each of R/G/B, and changing that is definitely not what I was looking for ), Power consumption (no effect) and Enhance colors (no effect).
So while color temperature makes a difference it doesn't seem to be the ideal... but I played with Display mode, switching it from Outdoor to Automatic, and instantly Google Maps became readable.
This is in my home office, which is presently lit by subdued outside lighting on a clear sunny day. I need to go outside and stand in full direct sunlight to see if Automatic goes to Outdoor and again washes out Google Maps displays to zero-contrast unreadability.
It still seems weird that Contrast is controllable (witness "Screen Adjuster" and several others) but there is no Contrast control in Settings.
Many thanks!
Im glad that helped
There is a new feature in the newest firmware (9.1.0.178 or .177) called "Flicker reduction". If this option is enabled the control method of the backlight changes from PWM dimming to DC (-like) dimming which helps to reduce screen flickering. Under the option there is following note: "Reduce flickering on the screen. This will affect color balance and auto-brightness control".
Today I have done some measurements to find out if there is a real difference in color reproduction, screen brightness, etc. between the two modes.
Device under test:
- P30 PRO 6/128 GB (VOG-L29), firmware 9.1.0.178 C431
- Notes: battery at around 35-38%, no screen protector (and cleaned screen)
Tools:
- X-Rite ColorMunki Display colorimeter
- Color HCFR 3.4.0 software (OLED profile) for measurement (PC side)
- Voodoo Screen Test Patterns V3.4 app installed on the phone (for the different color patterns)
Measurement method:
- HCFR patterns: primary + secondary colors (fast) and grayscale
- The different color patterns were selected/switched by hand on the phone (this can cause some error in the measurements)
- EMUI color profiles: vibrant/warm and vibrant/default
- (The measurements were performed in ambient light)
Results:
Luminance, white point, color accuracy:

Grayscale:
Color gamut:
There are only small differences in the screen's color gamut using different dimming methods and brightness levels.
To sum up, the color gamut of the screen is nearly equal to the DCI-P3 color space (covers the sRGB color space in 100%) using the "vibrant" color mode. (in case of the "normal" mode the screen's color gamut is equal to the sRGB color space, but these measurements are not part of this test...)
For details (CIE diagrams), please see attachments.
Flickering:
If I look at the screen I can't identify which mode is currently activated, there is mainly no difference.....but if I look at the screen through a camera the difference is visible and noticeable. In case of the PWM control the screen flickers in the whole brightness range, while using DC (-like) dimming the flickering is less significant and is only visible using lower brightness settings (typically ~<25%)
Summary:
It can be clearly seen, that the vibrant/warm preset produces much better results in terms of color/grayscale accuracy (using both settings).
The DC (-like) dimming reduces screen flickering while there is no significant difference in the visual experience compared to the PWM control.
Very nice work. I forwarded this to our Display Analyst to see if he has any comments.

Thank you very much!
Small update:
Added CIE diagrams and a short summary about my findings on the screen's color gamut to the OP.
Congrats for your analysis. I had the same doubt. Tks
What about battery consumption, which is better among the 2 methods?
This needs to be more visible! Thank you!

✓ Energy Ring can be configured from a width of 1 pixel to a donut thick ring
✓ Energy Ring puts almost 0% load on CPU, as it wakes up only to reflect any change in battery level
✓ Energy Ring's direction can be configured as clockwise/bidirectional/anti-clockwise
✓ Energy Ring can hide on fullscreen content (apps, videos, images, games etc)
✓ Energy Ring can be configured to change colors automatically depending on the live battery level
✓ Energy Ring could have a mono color/multiple color segments/gradient (pro)
✓ You can literally assign any color in the world for your favorite configuration
✓ Energy Ring has a number of cool animations whenever a power source is plugged into your device
The App in action on a Galaxy Z Flip, Fold 3, Pixel 5a: (Looking for photos of your device, please attach them!)
All that is cool! But what about Energy Ring consuming Battery?!
This is one of the most exciting question for me to answer. Energy Ring more than anything understands that you need to utilize your battery efficiently (after all, that's why you installed the App, right? .) Energy Ring sits on the screen silently putting almost 0% load on CPU, if battery level changes, Android wakes up Energy Ring. Once awake, Energy Ring quickly updates itself and goes back to sleep. And to be that extra efficient, the Ring goes on deep sleep when you turn off the screen, meaning it doesn't even read changes in battery level when the screen is off.
Accessibility Service Requirement:
Android requires Energy Ring to run as an Accessibility Service, to be able to display on Lock Screen. It does not read/monitor any data, whatsoever. This is especially useful for people who have disability to read numbers and work better with visual data.

Is there any way to keep the ring on till the notification are read and not a fixed time?
