Hello Friends of the Forum. I've been researching something for many years, and I've never found a real solution. The next, virtually every smartphone enters the maximum brightness mode when Light sensor exposed directly to the sun, but this does not happen if you are in a shadow, such as a sun umbrella or a tree. Many people make confusion because this maximum brightness does not depend on being selected the auto brightness, is only disabled on developer option. I dream of getting access to this maximum brightness without the need of the sun, because it would be very useful on cloudy days with a lot of clarity, or in moments of shade on the beach, to make video calls on the street during the day. If you want to take a picture of the sunset, for example, the brightness is also not activated, as the sun will not be reflecting directly on the sensor, but on the back of the device. My intention is not to use the maximum brightness all the time, but to recalibrate the brightness sensor, so that it activates the "boost" without needing the direct sun in the face of the device, but in any bright environment. I just want to walk in the street during the day with the screen really shining in my face! Does anyone have that same interest of mine? Thanks! (I'm using a translator, I don't speak English well, sorry for anything).

I'm not a programmer, but I would like a simple app/mod that allows us to set the 'target brightness' level with a slider, but leave the backlight in automatic mode so that it handles different environments.
Adjusting other parameters such as the time-delays would also be handy.
Give a toggle for whether we want the trackball to light at all! - I certainly don't want that blazing light in my face at night unless we can figure out a way to dim it.
Finally make the screen come on at minimum brightness every time it is switched on, then take sensor readings and ramp it up to the appropriate level (quickly snap-up if the sensor says its full-sunlight-bright). I hate being in a darkened environment and having my screen come on so blasted bright that I can't see for the next 10 minutes after answering a text message.
I realize we need the .29 kernel source before this is likely going to be possible, but I'm just throwing it out there.

try this app in the market- it will let you turn off the ball if you want

I'm looking for an application to adjust the color temperature of the display (not the brightness. the color temperature). There's a program for PC/Mac/Linux called F.lux that adjusts the temperature for the time of day (warm at night, and more sun-like during the day). I've been looking for something even remotely similar on Android, but no luck. Any suggestions?
Thanks!
PS, the ultimate purpose of adjusting the temperature is that the extremely blue displays many of us use in the evening (LCD TVs, computer screens, phones, etc.) can disrupt sleep patters causing insomnia at night and difficulty waking in the morning. It's not the brightness of the display that's the problem, but the temperature of the color.
[and yes, I've searched. only suggestion was a ROM for a different phone]

This is an excellent idea, the blue hue sh*ts me to tears. Had a look around but can't find anything like it. Will keep an eye here and see how you get on!
Good luck, and welcome to XDA
Not sure if this is a Nexus5 or Android issue ...
Not sure if this is because I'm moving from an AMOLED to a IPS LCD ...
but I find the Auto-Brightness less of a function and more of a roller coaster ride.
- At home, in a well lit environment, the phone defaults to max brightness, which doesn't seem correct.
- In a dark room, upon wake of the phone, it correctly selects a lower brightness, yet will randomly ping up to max brightness, then settle back down.
The screen on the Nexus5 is absolutely gorgeous, but it just can't seem to select and lock onto the proper brightness level with respect to ambient light.
Is anyone else experiencing auto-brightness wonky-ness? Are there any potential fixes?
Everyone AFAIK suffers from it on nexus 5.
I have a horrible feeling it's a hardware fault, as none of the other Google devices on kitkat have this issue.
yeah the auto brightness seems to be too aggressive, but i'm sure custom roms will have the ability to tweak the auto brightness settings. i think even gravity box has some tweaks for the brightness
If you download Android Sensor Box, you can check the Light sensors. I think it may be bugged with Halogen lighting (correct me if I'm wrong). My home is ~ 18 years old, and we have some bulbs that have not been changed yet (yellow). Sometimes when I use my N5 under those lighting, the sensors go whack and don't register properly picking up 0lx, then spike up to 30000lx. Once I move to areas in the house with newer bulbs, the sensors work normal, picking up the right readings. I'm not sure if it's a rom issue or hardware issue, but my cousin also has a N5 and his worked fine. I tried flashing a new rom and mine still acted up fresh after boot (1st app installed after fresh flash was Android Sensor Box to test).
As a rule I don't use auto brightness. Just get something like lux or install exposed and enable a mod to let you adjust it by sliding your finger across the notification n shade. Easier and faster.

I find that autobrightness will auto-turn on, even when i don't want it to.
There is something funky about it, I can either make the phone too dark (using lux) or too bright (using default settings)
I'm still not happy.
Tried Lux, tried adjusting the brightness tables via Gravity Box, used Twilight (to dim at night), no matter what, N5 just wants to be at full brightness all the time!
I had my Nexus 5 in the cinema the other day. The phone was sat in the cup holder by the chair for the most part of an hour when I quickly replied to a text. On turning the screen on it was on full brightness and what's worst is it took around 10 seconds for it to go down. There is definitely something not quite right with it.

Hi, I have been experiencing this as well, so I attempted to fix this at ROM level. The solution requires Xposed framework, so it works only on rooted devices (related discussion).
Hey everyone,
I would like to present you app that I created to automatically adjust screen brightness. Tested on LG K8, Android 6.0. App is using front camera to determine lighting in smartphone environment. I created it because I recently changed my phone and as it turned out this one does not have light sensor, and that was cumbersome for me (day or so after using phone I faced situation when I was outside, it was very sunny and brightness was set to like 10%. It was impossible to unlock phone because I couldn't see anything on screen even if I tried to cover phone screen from that light, so phone was totally unusable!). I didn't find this kind of app on Google Play so that's why we have this thread.
FEATURES:
- automatically adjusts screen brightness
- automatically turn on device boot
- 5 frequency options
HOW TO USE:
1. Download.
1.1. [6.0+] Give permissions.
2. Choose one of available options (I recommend using medium refresh rate).
MORE INFORMATIONS:
Of course app will be improved. I want to add notification with brightness adjust bar, and improve algorithm that is determining what brightness level will be set.
FREE DOWNLOAD:
App in attachement.

THANK YOU FOR YOUR VISIT AND TIME!
Thats good for device doesnt have light sensor
Great idea... However on my k8 its a bit confused... i tried it in the office during daylight, it was quite dark instead of bright and when i covered the front camera its become bright... maybe you could put some options there to manually adjust intesity levels related to the picture brightness?
Good idea

Great and usefull
Do you support this or are still developing it?
