Weird green overlay? - Nexus S Q&A, Help & Troubleshooting

I have had this problem on cm10, baked and now on factory ROM. With various kernels. When I unlock sometimes, the screen is like super green for a sec then it works. Sometimes its froze on it too. Any fix?

Things I've seen work are use a kernel without voodoo, increase min cpu speed or up the voodoo color settings to default or higher. It's very common though.

You wont have that with marmite kernel.

It has to do with how the gamma is set for the screen in some kernels. To get the really nice rich colors you need to set the gamma significantly lower than stock. This results in the "green flash". If you want good colors you need to live with it.
Morfic did figure out a way to get rid of the green flash while maintaining dark colors in the ICS Trinity kernels. However, the flash is back in the JB trinity.

[Q] How do you change the vibration intensity?

Just installed a new rom and it vibrates like crazy. Is there a way to change how hard it vibrates or do I need to jump over to a new rom? It's the bionix rom by the way.

CM7 is the only one I know for sure allows vibration intensity adjustment. I don't blame bionix, however. The Gingerbread leak had the same massive vibration as compared to the froyo stock.
try looking up the trinity kernal, it fixes the vibration intensity for some roms
Aww. I thought it would be an easier fix than that, like it was some setting that I just didn't see. Thanks guys

Imoseyon kernel link?

I noticed this in new gummy. What are the advantages over imnuts kernel?

I love his kernel, only part I don't care for is the preinstalled overclock. Voodoo Color is nice though :]
edit: Heres the download http://cl.ly/9BnL/imoseyon_leanKernel_voodoo_0.13.6.zip
Do I install this through Odin or CWM?
CWM. Just "install zip from SD card"
Just FYI, this is already in Gummy2.0, so if you're on that ROM then you are on this kernel.

Overclock is not enabled by default. The kernel allows you to oc up to 1.4ghz with voltage control or a similar app. If you don't like it don't use it.

The way the changelog is phrased it seems like it's overclocked by default, not only that but when I started up Voltage Control for the first time the advanced section was up to 1400, general was 1000mhz though. Overclocking confuses me.

Yeah apparently he's got voodoo color on it that's why the colors look different than IMNUTS' kernel. In fact, here's a quote from the man himself.
imnuts said:
It will work, though it wasn't a simple edit as the files that are changed didn't have all the same methods the files that voodoo color has and makes changes to. Imoseyon seems to have gotten at least some of the voodoo color changes built into the kernel though.

This is so awesome! Finally the colors look correct instead of way oversaturated !!!
Sent from my SCH-I510 using Tapatalk
Agreed! Also, according to what imnuts' said(unless I'm misinterpreting) that's not even the full Voodoo Color, so we can look foward to an even better version in the future :] Voodoo Color was made for Super Amoled and not SAmoled+ so that's why he can't just copy it over.
Did anyone take pictures of their Charge before/after voodoo color?
I read over at the Gummy 2.0 thread something about IMoseyOn's kernel not having support for HDMI output. I don't have a cable, I just ordered it, but can anyone confirm.

If it's true you can expect it to be fixed by the time your cable arrives.

I've had no issues with the HDMI out on this kernel. Used it to watch Netflix this morning on the big screen and it worked perfectly. I'm not using gummy, i'm on humblecomb. Perhaps it's a gc issue and not the kernel.

FYI about Voodoo Color: the color-correction only kicks in at 100% brightness, so if you're like most people and leave auto-brightness on, don't expect colors to look better because the calibration won't be in effect.
Super AMOLED+ also has much less of an inherent blue tint than Super AMOLED did, so I'm not even sure the difference is very noticeable at full brightness.
What would make a definite difference are the text sharpening enhancements (the Charge still applies an overly aggressive sharpness filter, much like the Galaxy S), but since text is far more accurately sharp on the + to begin with due to the loss of Pentile I can't really tell if that's active in this kernel.
So, bottom line: Voodoo Color was made for the screen on the original Galaxy S, and ours is a good deal different (and improved)... so don't expect it to make a huge difference like it did on the Fascinate. If/when supercurio makes a new Voodoo Color implementation specifically for the Galaxy SII, then we may see more of an improvement (but again, never as much as with the original Galaxy S because our screens are just better to begin with).
It's a huge difference. Colors went from oversaturated to balanced. White looks white instead of blue.

So just curious, I flashed this kernel and voltage control still says it's incompatible with my kernel. Also, when using any cpu app, it still shows my max as 1000mhz.
For the record I didn't get a wipe when I flashed it using cwm.

[Q] Any ICS ROMs that fix auto brightness bug?

Are there any Ice Cream Sandwich ROMs for the Nexus S that don't have the flawed auto brightness implementation? I'm sick and tired of straining my eyes because the screen is always too dim. The apps from the market I've tried to fix this problem don't really work - they keep falling asleep or something.
What I really want is a ROM with the minimum brightness tweaked to a higher setting... has anyone seen a ROM that does this?
Cyanogen 7 had a setting built in to customize brightness. You tell it what brightness to use at different light sensor values. I assume CM9 has the same option but I am not sure.

Nah it's broken in CM9
Back when i was using the 2/26/12 cm9 nightly you could tweak the levels and it worked fine. (I am using the nexus s 4g, not sure if that matters) Try that nightly. The setting is listed under display settings. Maybe they broke it since then or maybe just the nightlies have it working? Not sure since i don't like the performance of ics on the nexus s and have gone back to the fast and fully functional GB.

THanks for the advice, I'll give it a try. I've also thought about going back to GB, but it just seems like such a bummer to give up on ICS!
These kinds of issues really make me angry at Google - it's as if they barely even test Android before shipping it!

General Questions about Screen and Battery

Hi There!
I got my wife one of these to replace her Motorola Defy.. She has a few questions I couldn't really answer...
1) She seems to be having problems with signal and therefore internet connectivity. All our other 6 devices wireless fine. It's running 4.04 Android Custom ROM. I read recently 4.04 users were reporting issues with the signal strength and wondering if I should change back to 4.03?
2) She says whites are not really white and when I compare to the Defy it would appear she is right.
3) She says the text doesn't look as sharp or crisp and again I am inclined to agree. I am not sure if this is a Pixel Density issue or a setting we can change.
4) Battery life is shocking. I'd say she is lucky to get 8 hours if she talks on the phone for perhaps 45 minutes a day. I am interested to know what a reasonable baseline expectation is.. Right now she is barely touching it.
Thanks for any assistance.
Hi,
I have been using ICS 4.0.4 as soon as it officially came out and I haven't had any issues with connection (let alone hear of any issues for that matter.)
Whites are definitely not as white as they are supposed to and thankfully there is a software modification called: Voodoo Control while allows you to adjust the gamma settings to change the saturation and tone of colours.
Regarding the sharpness, changing the gamma settings may help in this department unless you'd like to change the pixel density via rooting/flashing custom ROMs.
To be honest, when I first owned this device I would disgusted from the battery life I was achieving. 8-10 hours per day. However, I am able to last about 20-30 now after a few modifications. In 4.0 you can view which apps are consuming the most battery:
System settings > Battery
Battery saving tips:
- Turn down the brightness 10-25% (Also turn off auto brightness if you can live with changing the brightness manually)
- Turn off data when not in use (switch to 2G if possible)
- Turn off auto-sync (or sync less frequently)
- Turn off GPS when not in use
- Turn off the screen manually before putting it in your pocket
- Turn off autorotation
Screen brightness is the biggest culprit so I'd turn that down to a comfortable level.
Basically, the more features you turn off that makes your smart phone "smart" the longer the battery will last.

Matr1x kernel has been around for a long time and is the most feature packed kernel. It also has been tested to save the most battery life compared to other kernels through built-in undervolt.

Is Matrix Kernel voodoo compatible
Yes, it's compatible. AirKernel is another option. There are a few on the DEV section you might want to check. ROMs, I would say: Bugless Beast, MIUIXperience, CyberGR, Brainmaster ROMs, AOSP+ and AOKPBlue 1.1

Where can I get this Voodoo Control? I only see a Sound Control App?
I answered your question in another thread. The color and sound controls are in the same application. If the kernel doesn't support it, it won't show up in the options. The name of the app was changed a while back.

[Q] Latency Issues

Does anyone have screen latency issues, and if so, how did you correct them?
I'm on Viper XL 3.2.6, Elemental X 5.2 and have basically reduced all OC/UV settings back to stock. When I go to wake my screen, the lock ring may be off to the side and it takes a second or two to relocate to the bottom of the screen. Then, it may unlock OK but when I go to do anything, there are delays. For example, I'll launch my Touchdown client and the PIN pad doesn't show up for a few seconds. Or I launch Apollo music and it takes a few seconds to show my installed music. Or my BT headset takes a while to connect.
All of this seemed more instant on older versions of this ROM, so I'm just wondering if there were any issues. I thought it was my overclocked GPU settings (3D 512 MHz, 2D 320 MHz), and once I reset those to stock it seemed to get better, but not as good as I think it should be. BTW, I am still getting relatively high scores in Quadrant Standard (in the high 6000s), so I know the thing is running fast.
Any ideas?
Thanks!!
I do not know if this will fix your problem but I was having the same issue. I noticed that when I went into the venom/ kernel folder there were 2 kernel images. I deleted the stock image and kept the elemental. Then ran the installer again and everything is working fine.

Lol don't think that's gonna work. That is for the venom installer I believe. Your kernel will not be there, and you cannot be running two kernels at once. Have you tried full wipe and flash a jb ROM keeping its stock kernel?
