[Q] some strange adaptive brightness randomly - Galaxy S 4 Q&A, Help & Troubleshooting

helllo
Even if I am using manual brightness set to max - when browsing for example XDA forums which has alot of white - I notice if i drop down the statusbar to check notifications - then go back into xda the screen dims down a notch. (Going from alot of black to alot of white)
This is with all auto-options set to disabled and at max brightness.
This also occured in omega rom, also MF8 base.
And sometimes after a while, it can go back to max brightness randomly. I feel its some sort of adaptive brightness thingy that is misbehaving - even though everything is set to manual.
I tried MGA but its the same thing - . -
and it happens randomly. then after a little while the brightness can go up to max again.......

There's an option in the display settings which is badly named but which turns off this behavior. I think it's named adaptative display or auto tone or something like that. It's the 2nd from the bottom.

I already have everything like this turned off

Same problem here. Couldn't find any 3rd party app to address this. Tried almost all brightness related titles in the play store. Hope someone will come out with some dolution for this. It's sooooo annoying!

Same probleme here....
That made now 2 weeks that I search a solution. All the options of auto-luminosity are disabled, luminosity set to the maximum manually, auto-tons disabled and eco mode off but despite everything, in a dark part, my screen dimmed. It is very disturbing because it dimmed then return in full luminosity etc.... It is a problem but beyond that, I noted that at the time when the automatic adjustment of luminosity occurs, the processor also loses in frequency. It still reaches a maximum at 1.458 ghz or worse at 1.2 ghz.. I tested several Roms: Stock rooted, Google edition 4.3, V8.0 Omega, the result is the same one. I tested several Kernels: Faux123, KT-SGS4 and Adam Kernel. I tried to block the processor at 1.89 GHZ (min + max) at a session of games but at the end of a few seconds, automatic reduction of the luminosity and decreased processor. I think it is not a hardware problem because much of users of Galaxy S4 have this worries.
I become insane with that! And my wife also
Is it possible that a developer integrates a corrective in next a Rom or perhaps make a tweak?

I think i know what's causing the issue.
When I got my phone I noticed the same thing. Apparently its a function of the software deep in the system(at least that's how I understand it). There is no easy way to turn it off. Basically it throttles the screen brightness depending on the average amount of white displayed. The more white the more the brightness is throttled. Not sure if it's to prevent the screen from overheating or to save battery or for both. It's kind of like how the screen can ramp up to a higher brightness when in auto than when in manual. I think it's a thermal issue, but not sure.

i also think its thermal/power saving related.
a kernel tweak should fix it.

Auto Brightness Control

I HATE the auto brightness min/max settings. I already searched this and found many other people saying the same. Is there any way to adjust the min/max?
What I would like is a way to adjust the dwell time on the changes / averaging of the sensor readings - mine seems to constantly change and I can't imagine that's terribly helpful for battery life.

Same here, sometimes it's not as drastic but sometimes it seems to go from 30% to 70%. Maybe not that drastic, but it appears to be quite a jump. I just use the power control widget if I need a big change in the brightness.
There needs to be a "gain" control for the auto brightness feature. And it needs to poll the sensor less frequently.

Personally, i hate it too .. thats y i just adjust it manually as needed. I really dont find the need to adjust it that often and i find that i also save battery life.

SET CPU problems with root?

Aside from being able to Wirelessly Tether my 3G connection from my Vibrant, I wanted to also control my CPU speeds. But with SET CPU, I tend to come across a particular problem. I would underclock to 100000 (min&max) with the screen off, but as a result, the screen won't turn back on and I would have to take the battery off and restart my phone. Clocking it to 400000 (both min and max) screen off leads to the same problem. Is anyone else going through the same situation? If not, what are you setting your CPU to, in regards to both screen on and off?
I have it set to 400MHz max/100MHz min for screen off, and it wakes up just fine so far.
What is your Governor setting? I was told to put it in "Conservative" for Vibrant.

Yeah I have all my profiles set to conservative. Do you guys think it has to do with the priorities, cause I have all of them set to 100.
It could, since there is no telling how to prioritize the settings, hardware/software might get confused.
you know I just noticed I got the same issue, sort of.
I have multiple profiles setup, and one is for charging via USB 800max/100min.
If the screen is off (400max/100min), and I connect the USB cable, guess what happens, three finger salute gets it back, hmmm.
OK I got it working for those who are having the same problem as I. All I did was I made my screen off frequency 200max/100min. For both charging and battery use, I have my cpu set at 1000max/800 min. It works flawlessly and I am noticing an increaSe in battery life...

OverClock?
I used SET CPU on my G1 and really loved the new life it gave my old hardware. I would like to open it up and see what my Sammy Vibe can really do. Is there a way to get some real OVER clocking?
Battery life is really not an issue for me so far.

we need a kernel that will enable it. its apparently not possible on the stock kernel...
I have been having the exact same freezing issue when the screen times out, I'm unable to revive the phone without pulling the battery. I have tried many different setting in Setcpu including those posted here. I finally just uninstalled it and everythings right again. Best to avoid this app for now.
Hey man i did that and i still did not work any other way to set it up.
Vibrant wont come out of Blank Screen
I used Set CPU and put it to the max 1000 and then the max on the other readings it forced closed and after the tmobile and Galaxy animations it goes to a blank screen.
Yeah, I uninstalled it after a week because it was just too unstable. I was getting freezes several times a day, which is unacceptable. Other people might have better luck, but my phone did not like it at all.
So far the only way I can get the program to work 100% is to not have any screen off profile. If I just set it to 1200 max - 200 min / conservative it works fine. Yet once I use profiles and screen off at 100, 200 or 400 it won't turn back on. Every morning it's the same thing, battery pull.
I have similar problem. As long as I am not using "Profiles" at all it is fine. Playing with profiles setting for a while, but not being able to make them 100% stable.
Another thing, if your screen does not come on, you don't have to pull the battery out. Just keep holding on/off button for 5-7 seconds, it'll reboot. It's not a complete freeze, I believe only display system (whatever it is) fails.
Stuck at Recovery Mode
Guyz,
I have firetrap sugar on Spice Mi300. Installed Set CPU.
Tried entering the recovery mode, the phone gets stuck at 1st screen with a line "Enter recovery Mode" displayed on top.
Please help.

[Q] G2 screen sometimes won't turn on

I have a T-Mobile G2 that's been rooted and flashed several times (cm6, virtuous, supervillainz, senseginger, cm7) and through I think all of them I noticed an issue with coming out of sleep where the screen doesn't turn on
it still reacts to touch (ie I can slide to unlock), and the bototm touch keys light up, but there's no backlight or picture on the actual screen
sometimes it takes several off-on cycles to get it to work... I've recently noticed (and may be just imagining it) that the trackpad wakes it up with a much better success rate
details:
HTC Vision (G2)
Android 2.3.3
Baseband 12.28b.60.140eU_26.03.02.26_M
Kernel 2.6.32.28-cyanogenmod-g58d929e [email protected] #1
CyanogenMod-7.0.0-RC2-vision
any ideas would be welcome before I lose it and start poking at the kernel, radio and whatnot
thanks,
L
happens to me in virtuous, never happened to me on CM (i havent tried cm7 yet)
i believe its a problem with the cpu scaling, ie when the screen is off, processor drops to 245mhz and when the screen turns on, speed doesnt scale up fast enough
i usually underclock my g2 to 599mhz (governer set to on demand) but if i go any lower than that, getting the screen to come on becomes a frustrating project lol
I have the same problem, its so annoying especially when someone calls. Its been mentioned in other threads and I'm sure its a known problem but like u I need a fix. Stock ain't so bad as long as u can see who's calling and what time it is without trying to wake the phone 20 times. Please will someone finally answer this question? Or do we all need to revert to cm 6.1 or stock????? Small problem but big outcry.

thanks, I downclock to 200mhz on screen off
I'll up it and see if it makes a difference
Are you using the screen off animations in CM7?
Sent from my HTC Glacier using XDA App
screen off yes, screen on no
Try disabling the animations all together and see if it helps. Also are you OC'd above around 1.2ghz?
Sent from my HTC Glacier using XDA App
I've disabled them for now, gonna see if it helps...
yeah OC to 1516MHz, do you think this affects it?
There was a known issue with CM7 not too long ago where if you had the screen off/on animations activated in conjunction with being OC'd at around 1.2 or above it would cause the sleep wake issues. Took 3 or 4 on/off cycles with the sleep button on order to get the screen to come back on.
The solution was either to disable the screen animations or not to OC very high.
The other remedy recommended earlier is also legit. Set your screen off CPU profile to around 300 or 400mhz. Your problem should be solved by tinkering with all 3 variables. Failing that I would recommend a wipe/reflash and/or hitting up some folks in the CM7 thread to see if anyone else has that issue after tinkering with the above solutions.
Good luck man, I know those little bugs can be frustrating.
Sent from my HTC Glacier using XDA App
thanks for the tips...
I've now upped the minimum clock to 400 across all profiles and turned off the screen off animation... if that doesn't do it, I'll turn down the maximum clock, and if that still fails disable setcpu completely
I will report back any findings

Seems like nature of the beast. I get it too. Are yall using setcpu? I think its an issue with it. U might try cputuner and see what happens. But it rarely happens now that i set my setcpu to conservative or smartass.
Sent from my HTC Vision using XDA Premium App
this is indeed an issue with downclocking the phone on screen off profile... as soon as I set the screen off profile to anything below the stock 806 mhz, the issue appears
I've reenabled both screen off and on animations, the issue still hasn't reappeared... so it's the downclock :/
I have seen it on Sense ROMs but not CM7, doesn't clocking your phone at 800 when display off eat up a lot of battery also?
I am, unfortunately, not that techno-savvy when it comes to cellphones. But I am having the same problem.
The most I get is a bit of back light, but everything else about the phone seems to be working. Is there anyone who could possibly help me figure out how the hell to fix this?

Do I have a bad xperia play?

Hey guys I'm having some concerns about my xperia play and so i want to know if i should be worried...
My screen flickers. ( Not on/off) but between shades. It's hard to explain but it drops between levels of brightness, but here's the deal i turn auto brightness off and it still flickers. Now i have noticed that the screen will dim ( flicker shades) with the orientation of the phone. Idk.
Also when I'm downloading the games thru xperia app it takes forever, i have high speed internet and I'm connected via WiFi but should i be expecting A 150MB download to take up to 45 minutes. Seems kinda slow to me.
Thanks in advance guys.
By Tue screen flickering if u mean the auto brightness increasing and decreasing immensely at times its normal since u cant turn off the auto brightness in our phone....
About the games..most of the games took 15-20 mins or less for me on an 8 mpbs connection

Is there some kind of other brightness settings, i turned auto brightness off. And I'm still getting fluctuations in the shade of color.
if you have root you can disable this, but it is only temporary as somewhere in the system it re-enables this.
create a gscript with su ability
start script below
echo "0" > /sys/devices/i2c-0/0-0040/leds/lcd-backlight/als/enable
end script above
do not include the start and end parts
lasts around an hour, stops the flicker in bad light situations

It wont turn off even if you untick it, its an anoying bug, hopefully custom roms/kernels will solve this, dont worry about the downloads, even with high speed internet, keep in mind most of the developers are small companies and cant afford expensive hosting, even the gameloft servers are slow imo

You can NOT turn auto brightness off on the Play, it is hard wired right into the os, even if you used an app or widget saying it if off it is NOT! there is nothing you can do until SE fix it or some members here mod the os,
All the Play's do exactly what your describing, lots of topic here and elsewhere about it, everybody moans about it!
And regarding downloads, things from the market download fast for me, very fast, but other stuff from other places can be very slow, gameloft for example, takes hours! just depends on the servers your downloading from.
Hey thanks guys for the information. When i get to a desktop I'll hit the thanks button for all of you. I think my WiFi was acting up last night, i was playing some zombies and downloading torrents at the same time.lol. anyways thanks guys again.

To be honest with you I like the auto brightness. I think is super responsive which other phones it seems like it takes forever to kick in which is why I normally shut it off

[Android 2.2+][11.11.2011][v1.3] CF.lumen (for Chainfire 3D)

THIS APP AND THREAD HAVE BEEN REPLACED BY THIS ONE HERE: http://forum.xda-developers.com/showthread.php?t=2711912
CF.lumen changes the colors of your Android device's display based on the position of the sun. With the default settings, your display will get a warmer tint (lower color temperature) when the sun is down, to look more like indoor lighting and less like the sun, which causes less strain on your eyes and doesn't keep you awake as much.
This is an addon for Chainfire3D, you need to have both Chainfire3D and Chainfire3D Pro installed to be able to use CF.lumen
With the default settings, blue tints will be reduced in brightness when the sun goes down. This reduces how much looking at the screen keeps your brain awake later at night. If you have sleeping problems, you should definitely be using this. Do yourself a favor and install similar software ("f.lux") on your PC as well - it fixed my sleeping cycle.
There is also a full-on sleep mode that runs on a pre-set schedule. By default it shows the entire screen in red, so as to not destroy your night vision when you look at it.
When you want the screen to look normal for a bit (for example for gaming or looking at pictures) simply tap the notification in the notification tray to disable CF.lumen until the next time you turn on the screen.
Additionally, it can also use the light sensor to automagically switch to sleep mode when it is fully dark. HOWEVER, you should be aware that most devices do not have a sensitive enough light sensor to detect the difference between house light and darkness, so this function may not work very well on your device.
Last but not least, a function is also provided to turn off the screen based on proximity sensor activity.

Works pretty well, except for that when it's enabled, it seems to somehow turn off the fade screen transition in CM7 when you hit the home key. The screen still correctly shrinks, but once it shrinks it just waits for a split second, then disappears. Normally it shrinks and fades at the same time. This isn't a big deal really but I figured I'd post it here in case I'm not the only one.

Still thinking about how to best do that. In the newer Android versions (Gingerbread and up) you actually HAVE to have that icon to make sure Android doesn't constantly kill the background service.
Alternatives are for example to restart the service on a timer, I think I'll build that in at some point.
CF.lumen updated to v1.2
Changelog:
- "Sleep in the dark" now checks for proximity as well as light levels
- "Bright light" mode added, switches to Day mode in bright light even when in Sundown or Night mode
- "Notification Mode" settings added. Can remove notification. WARNING: Doing so may lead to CF.lumen being shut down by Android at random times.
Can you add the option for the bright light mode to switch to night sundown mode instead of day mode? I'm also seeing 7-8% CPU usage with the proximity sensor enabled. I like the idea of this feature for battery savings (example, putting the phone in my pocket and having the screen turn off immediately) so if there is any way to tweak the battery consumption it would be great! Would you be able to have the icon displayed change to reflect the mode it's in? For example a sun for daytime, moon for sunset mode, etc.?
One last thing, noticed that the Sleep filter setting does not get saved with version 1.1. It says Unknown even after you have selected a filter.
v1.3
Minor bugfix release v1.3:
- Minor crash fixes
- Current color filter display no longer says "Unknown"
- CPU usage reduced
- Power usage reduced
