[Display] Problem with Low Brightness and dark spot - Nexus 5 Q&A, Help & Troubleshooting

Hello guys,
I have a problem to display of my Nexus 5 and would like to make sure that others are not. I checked other Nexus and saw that some have this problem.
The problem occurs when we have a kernel that supports the backlight dimmer as the Franco.Kernel or the Elementalx Kernel. If enabled through the app franco.kernel updater Kernel Setting, putting the display at minimum brightness and white backgrounds I notice a dark spot in the lower left corner of the display. Obviously if I raise the brightness of this stain disappears. I am attaching some to better understand the problem. Also check you. Thank You

Question about auto-brightness

I don't really see a difference in brightness between auto-brightness and manual on lowest setting. I tried changing lighting conditions of the room, even covering up the light sensor with my hand to see if it changed. I still didn't notice any change. Is the change supposed to be dramatic and noticeable or very subtle? My girlfriends Incredible has a very obvious shift in brightness when auto-brightness is available, I don't see any on my NS.
Is there an app or way to test to see if my ambient light sensor is even working properly?
BTW im running CM7 RC4 with Netarchy Kernel, although stock 2.3.3 was the same. I'm also using different color profiles, but I don't think that matters.

[Q] Remove screen dim just before timeout/lock? (voodoo colour issue)

I've looked at past threads, but found no resolution to this.
I'm running voodoo colour with deep black settings and everything looks great, except right before the screen times out it will dim to its lowest setting and force the amoled panel to turn a sickly yellow/green hue.
I would like to disable the dim aspect and just let the screen time out by shutting off completely. Is there anyway to do this? I'm running the latest version of Pixel Rom with Air Kernel 4.2. I don't have auto-brightness enabled.
i am having the same issu i dont have to yellow tint in low light
but still i whould like to disable the dim it is disturbing my daily use of the device
i too dont see any point for this time out before the screen turns of
and i cant understand why when plying a game i need to touch the screen every 25 sec to get rid of the dim
thanks
I remember seeing something about auto-brightness light sensor tweaking back when I was using NV rom last year but I don't know if that would apply or not.
Does anyone know if the custom apps on the market avoid this?
edit: Tried Tasker for a full screen-off solution, and a bunch of other apps. Wasn't able to get the results I wanted :I
I have a Samsung Captivate and I am running a kernel with voodoo color support with this same issue.

[Q] Reduce minimal brightness on Nexus 7

I'm running SmoothROM with Bricked 0.55 kernel on the Nexus 7.
The minimal screen brightness (5) is too high for reading at night; how can i reduce it?
I tried in the display settings to set custom levels, but the lowest one cannot be changed.
Any clue?
Thanks in advance.
I use this app for that purpose.
There are also ones with colour tints that can be nice if you prefer that.
Interesting alternative to dimming the LCD lamp. Will try it as soon as darkness creeps in.
Thanks!

[Q] Is the Auto-Brightness Functionality wonky on the Nexus5?

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).

Auto brightness very bad/too dark.

I'm not sure what it is with this phone's auto brightness but comparing it to my old nexus 5 I can see that this phones screen is always darker. I know autob its working because I sometimes see it change automatically but its just always set to be way too dark. I
f anyone else has this problem or know how to fix it without having to manually adjust the brightness that would help a ton.
Also if you changed your lux levels please post those.
On and also I do have the official screen protector on if that matters.

Yes, it is a little dark, you can go to settings/display & light and hit the little gear icon, hit adjust and set up the screen brightness you like depending on the ambient light.
i am facing that some time while scrolling brightness increases for some millisecond and come to normal. i found that is twitter, some huge page in browser page.
can any one tell what could be the issue hardware or just a software bug which can be fixed with other rom installation.
