I know many of you have said that the Nexus 5's auto brightness is a bit whack. Quite honestly, compared to my Nexus 4 and iPhone 5, I feel it is on the bright side. I took the recommendation of getting Lux, and am wondering what are good settings?

I have my links setup the following (01/24/2014 setting):

Code:
Lux Brightness
0     1%
1     6%
2     8%
4     10%
10    12%
20    17%
40    17%
150   22%
350   30%
600   45%
1000  80%
1600  94%
10000 100%

Would appreciate any feedback and am searching for what works the best for a good combination of readability yet battery savings.

My frustration seems to be it's very easy to have a phone register 0 lux even in an office setting, and as soon as you tilt it the right way it will pick up anywhere 1-10 and cause a huge jump. I walked from my bathroom which was completely dark into the hallway which had a light, and my phone was still picking 0 lux. If I happen to angle a little better it reads the light and bam the screen lights up. Quite annoying because my iPhone will pick up the hallway lighting even if it isn't direct and that bright and the screen already starts to get a bit brighter...

I swear I've always been fighting the issue of dynamic range with autobrightness in Android. It's quite frustrating.

I just applied those settings (mine were a bit of a mess) let's see how it pans out! I'll let you know what I think.

I think there is something wrong with the hardware of the N5 or the software in KitKat. I occasionally get a reading of 30000 lux in a dimly lit room. A few other reviewers of the Lux app also reported this problem. I still get a brightness spike sometimes with built-in auto brightness and with lux turned off so it's not related to Lux. Anyone experienced something similar?

I have occasionally seen this as well. I have never used Lux but one time my auto brightness went all funny so I downloaded an app to see the sensor output and there were spikes like you describe. Rebooted and haven't seen them since. Maybe a driver issue?

Reboot doesn't help in my case but it happens only in a very specific lighting condition. Anyway, hopes it get fixed in the next OTA. It's kind of annoying.

Lux works well for me but it doesn't appear to recognize any natural light reading is less than 0 lux. Is that a limitation or a setting issue? I can get a reading of 0 lux in my living room at night but I also get a reading of 0 lux in a dark movie theater. I'd like the movie theater to be even more dim than my living room but it all appears to register as 0 lux in the Lux app. Any way around this?

The sensor has very poor resolution in darker areas I find. Hopefully it's a software issue that can be fixed in an OTA update along with the spikes to 30000 but hard to say if it's software or just a crappy sensor.

Looks like the spike is still there in 4.4.1

Just want to say thank you for the profile! Giving your values a try and so far I'm liking it after half a day of use.

Been using Lux for a while now, but I've always only had 1-2 values and settled. I'm very lazy so having setups posted is perfect for someone like me.

Also, this thread has good information on the issues with the censor/collector. I had no idea these issues were present. Hopefully it's software and can be fixed.

    Feel free to share your profiles you guys! I want to know what your eyes like, not just mine.



    Okay, one more revision.

    I was going through some in car reading like with the dome light on or even in the dimmer areas of my room, and I noticed around ~20 lux or so my brightness was way too high, so I turned those down a bit more!

    Code:
    Lux Brightness
    0     1%
    1     6%
    2     8%
    4     10%
    10    12%
    20    17%
    40    17%
    150   22%
    350   30%
    600   45%
    1000  80%
    1600  94%

    Give Velis Auto Brightness app a try. I've been using for a while and much prefer this over Lux.
    A lot easier to configure as it shows you a graph. Also it reacts a lot more faster to light change. Again this can also be configured easily.

    500 - 35%

    30000 - 100%
