[Galaxy Note GT-N7000 General] satishp:
Not exactly a hardware "issue" but maybe more like a hardware "limitation" of "Pentile" AMOLED. Samsung has hidden this issue in the Original Galaxy S and in the Galaxy S3 by lowering the gamma which results in darker images but "NO" or "Invisible" clipping hence satisfying consumers. Due to the lower Gamma on those phones, darker shadows seem to blend into eachother hence we dont see any clipping as darks are "Dark". And hence, when consumers dont "see" any artefacts, banding or clipping on their videos and images, they are satisfied. But this is at the cost of "dull" whites or artificial whites and lower overall perceived brightness.

As the Note has its Gamma cranked up, White looks white. I may even go forward and say that the Note produces the best whites ever seen on any AMOLED panel. Hence web browsing looks richer, colours look richer and the overall perceived brightness is again higher than other devices, But this again comes at the cost of clipping in darker shadows and hence poor looking videos and images, blocky pixellation,etc

So in the end, everyone is ready to sacrifice their "whites" for a clipping free display. Thats how it works out for consumers. As long as they dont "see" the problem, they believe its not there. So this may be a limitation of "Pentile" AMOLED and lowering the gamma may be Samsung's way of hiding the weakness.

The Galaxy S2 has an overall best screen which I've seen and thats due to the RGB AMOLED Technology. Colours look richer, the percieved brightness is higher and no clipping either. Thereby best of both worlds.

gamma

1) I saw some minor fixes on this thread http://xdaforums.com/showthread.php?t=1715416 but nothing really gets deep down to the problem. Those fixes are actually some kind of effects, they aren't so good. They talk there about some kernels that helps the black clipping issue.

2)I have found an apk that is called voodoo display filter, can you check it out? it does seem to enhance the black.

3)As i was playing around with the screen settings on cm9, i noticed that if i set the screen scenario to VT, the mode to MOVIE, and the outdoor mode to ON, i can see down to number 4 on the gamma test image (usually with the default settings i can see everything down to 1).

[Galaxy Note GT-N7000 General] satishp:
You are talking about the screen adjuster app which in my opinion is neither a fix nor a workaround for the problem. It destroys the blacks and uses the screen out of specification.

I have searched everywhere but couldnt find the apk for vodoo screen tuning. So, couldnt try that.

Anyways, this issue cannot be resolved with an app but only a kernel which supports gamma control.
[Galaxy Note GT-N7000 General] gbb14:
You can find the app on bazaar android, i think it was made by super mario super curio, or something :o who used to work on this issue, and had a thread of over 50 pages, until he decided to quit the work because of flamers and stupid people.

I've had some ideas:

Can the devs add some new settings under cm9>settings>advanced>screen>mode ? ooooor instead of bumping the gamma on outdoor mode, to lower it?

regards
[Galaxy Note GT-N7000 General] baz77:
Op please change thread title, as it is hardware.
[Galaxy Note GT-N7000 General] satishp:
Its not a hardware issue. It can be fixed by correcting the gamma at the kernel-level. I never said its a hardware issue. In my previous posts, I just said it may be a hardware limitation of Pentile AMOLED panels at highier gamma values.
[Galaxy Note GT-N7000 General] pboesboes:
You seem to misunderstand what gamma is. Gamma does not affect the white and the black values, but what lies in between. No matter how high or low you set the gamma correction, pure black and pure white will look exactly the same. Gamma also doesn't make colours "richer", that's saturation's job (and maybe contrast, depending on your definition of "richer").

And I would guess the S2 is brighter not because of gamma settings (as I just explained, that is impossible), but because the pixels are larger and occupy relatively more surface area. Also, the S2 is notorious for having impure whites (usually with a blue or yellow hue, IIRC).
[Galaxy Note GT-N7000 General] :
So its due to hardware not software
[Galaxy Note GT-N7000 General] satishp:
I do understand what gamma, saturation and contrast is. But I didnt know that gamma never affected blacks or whites. My mistake. I have seen that it affects other colours though. Increasing the gamma gives an "unnatural" boost to the overall image. This is doesnt make images saturated but seems to make certain colors appear brighter.

I still believe that lowering the gamma on the Note's screen can solve all the clipping issues.
[Galaxy Note GT-N7000 General] pboesboes:
I think so too, as it has for the Galaxy Nexus. Still, I'm not sure we'll ever see this fix. Supercurio has given up and no other dev seems*to have stepped up to the plate. Can't really blame them, the impression I get from Xplodwild is that the drivers are a nightmare to work with...
[Galaxy Note GT-N7000 General] CONTACTMC:
The only reason I kept my Note was because I was pretty sure a fix would be forthcoming from Supercurio or some other dev wizard, I am pretty dissapointed that it has not happened, but I am pissed at Samsung for making an otherwise perfect device a dud.

I bought the Note not as just a phone, but to watch movies on as well. And even now it is in the press they still ignore the problem.

I dont think I will be buying a Samsung again for a good time, I never had any such problems with my htc devices, and from what I can tell when a problem is found, they accept the issue and fix it, Sansung just stay silent and run with your money fu#&ers!
[Galaxy Note GT-N7000 General] satishp:
I wonder why there is still no kernel for the Note which supports Gamma Tuning. The Lean Kernel on the Nexus fixed all the clipping issues on that phone.
[Galaxy Note GT-N7000 General] gbb14:
does that lean kernel have gamma control or is it implemented in the kernel as is ?
[Galaxy Note GT-N7000 General] :
Speedmod has some tuning done by hardcore
[Galaxy Note GT-N7000 General] pboesboes:
Gamma tuning?
[Galaxy Note GT-N7000 General] :
Not sure, some report less issues on k3-7 and k3-11
[Galaxy Note GT-N7000 General] satishp:
The last time I discussed the problem with hardcore, which was recently, he said that Gamma control is a value present under the MDNIE settings, but he hasn't touched it. He has only tweaked the sharpness and the color value and he said there are many other parameters under the mdnie settings which may also be the reason for the clipping but he didnt mention which ones. He told that he might look into those values but didnt mention when. I still follow his thread and as of now, he hasnt mentioned he did anything to control or fix the clipping. Nothing in the changelog.

The Gamma Control is a feature implemented the LEAN Kernel for the Galaxy Nexus. The kernel can access and edit the gamma of the display and the Gamma Control implemented in this Kernel has solved the same clipping issues on the Galaxy Nexus. This is totally different from screen filters like Screen Tuner which makes the screen work out of spec and can do more damage than good. Moreover, I dont even consider such screen filters even as "workarounds" as they destroy the contrast and only do the job of just hiding the issue.

But a kernel like Lean kernel, corrects the gamma at the kernel level and hence, the contrast is maintained and the screen doesnt work out of spec.
[Galaxy Note GT-N7000 General] satishp:
Did any one try the Liquid smooth or LiquidBlack ROM by firasusman. Those ROMS claim to have gamma control built in but I havent tried those ROMs yer as I'm addicted to Paranoid Android's tablet mode. :)
[Galaxy Note GT-N7000 General] pboesboes:
I've posted in Q&A about this:

Almost seems too good to be true...
[Galaxy Note GT-N7000 General] satishp:
Should have been in general. The response in Q&A is quite slow. I feel most people visit the general and development forums more often than Q&A. :)
[Galaxy Note GT-N7000 General] pboesboes:
Looks like you're right :p
[Galaxy Note GT-N7000 General] satishp:
How come CM9 being one of the more mature kernels have gamma control disabled? Any ways to enable it? Or any nightlies which have this feature enabled?
[Galaxy Note GT-N7000 General] pboesboes:
I've been using CM for a long time now, and I've never seen gamma control in it. It's open source so you could concievably put it in yourself. :p
[Galaxy Note GT-N7000 General] satishp:
I have tried both Paranoid Android 0.5 and staxxtanium Paranoid android which I'm presently running. Both have gamma control under mdnie settings but unfortunately greyed out. :(
[Galaxy Note GT-N7000 General] CONTACTMC:
Can someone please try the LiquidBlack rom and test this gamma control out for us? I will root and flash it in a heartbeat if it works, the only reason I have stayed stock is because of my hope that samsung will finally own up to this and offer repair under warrenty. At the moment I dont see the point in sending it in, the girl I spoke to at Samsung said the Note she had in the office had the same problem so it must be a feature...lol, so I guess untill that actually admit there is a problem and find a fix, they will just send it back to me with the same problem.

Also guys please keep voicing in this thread on samsung developers :

[Galaxy Note GT-N7000 General] CONTACTMC:
I have asked about this in the LiquidBlack thread, the OP has posted since my question but seems to have ignored my post?!

I also found this, looks like Supercurio just ditched the Note for the S3, I hope he finishes display expert before the Note 2 is released or the S3 crew will probably get ditched as well...lol

[Galaxy Note GT-N7000 General] satishp:
If tuning the gamma does fix the problem, I feel the Gamma control feature should be a part of every Custom ROM as every user should have the flexibility to use the ROM of his or her choice without having to feel "forced" to move to another ROM just because, the ROM he is on has a lot of clipping and doesnt have any means to correct it. This feature should be implemented at the kernel level and ROMs should provide a gateway to access this feature within the android runtime environment to tune the gamma. Most CM9 ROMS already have this value under the advanced>screen settings but the Gamma control feature is unfortunately greyed out. Once, we are able to find a sweet spot which eliminates all the clipping generally for all devices, this value should be pre-tuned in the stock based kernels like speedmod for example. Hence, even stock users can have images and videos free of clipping without having to change anything on their own.
[Galaxy Note GT-N7000 General] CONTACTMC:
Agreed, but can u try LiquidBlack out for us to see if it actually does reslove the issue, then we can start an awareness campain with the rom devs if it does.
[Galaxy Note GT-N7000 General] HornedOni:
I'm currently on Speedmod K3-8, since K3-7 the black crushing has disappeared completely for me, and as far as my eyes can tell, it didn't mess up the blacks at all.

People reported in the speedmod thread that the black crushing returned for them in the newer versions. As far as I know, Hardcore is still trying to find out what exactly is happening there.

EDIT: Scratch the above. I just updated to K3-11 on 4.0.4 and I still don't get any black crush.

Try in a dark room and then report back. We just cannot take someone's word for it. We need a proof.
[Galaxy Note GT-N7000 General] satishp:
The gamma control on that ROM is not at the Kernel level. I got word from the developer.
[Galaxy Note GT-N7000 General] CONTACTMC:
To be honest I have given up on this, as soon as I can I will probably be getting myself a One x, or if htc bring out something similar to the note I will have that, apart from the blacks not being as black as amoled the super lcd2 screen destroys amoled in every way.

Samsung have for lack of a better term ripped us off.

Boasting that it is great for movies bla bla bla. ..what a joke.
[Desire HD Q&A, Help & Troubleshooting] SpiritStealer:
hello guys.... i'm facing somehow starnge problem, here goes what happened, i downloaded some apps including 4EXT Recovery and i said that there was a newer version of the touch recovery to install so i did, and restated and tried to enter the recovery mod "power + vol down"

but it didn't work and i ignored for later on .... after few hours i tried to mute the phone and then it hit me that the vol down isn't working, i tried to press hard but no use... i tried to restore the recovery version that i normally used but no luck... and even tried to install another rom "i'm now using android revolution HD 6.3.3" but no luck.... the volum up key works perfectly and the volum down feels the same as always, nothing changed and it feels like working but it's not .... so have any one heared of my problem or faced it ?????!! hopefully i find the answer here...

i tired to search the forum but no luck every resualt was about hardware problems which i don't think i have" at least i hope so"

Device: DHD

ROM : ARHD 6.3.3

ROOTED, S-OFF
[Desire HD Q&A, Help & Troubleshooting] targett:
My wife and I both have DHD's and are both having trouble with our volume up button!

Mine = fully rooted and flashaholic!

Wife = no root, no changes from stock!!!

They are both almost 2 yrs old now so think its just old age?
[Desire HD Q&A, Help & Troubleshooting] glevitan:
ok, volume rockers seem to be a common issue in these phones. To get to recovery you can use adb commands....plug the phone with usb debugging enabled and in the PC open a cmd as admin or a terminal as root, then type: adb reboot recovery....

make sure that u are running a touch recovery to avoid issues...
[Desire HD Q&A, Help & Troubleshooting] SpiritStealer:
Thanks for your help glevitan but the thing is that getting in recovery is not really the main topic of the problem cuz i was getting to recovery through the app or throgh advance power menu.... the thing is i'm trying to find out some way to fix it through software rather than hardware solution, if it's possible since the phone didn't actully have an physical issu, and it just suddenly stopped working after updating the recovery ..... hope to find the fix. and thx again
[Nexus S Themes and Apps] martinaif:
I was wondering if anyone can make a flasheable fix to get the ICS animations back on my Nexus with Jelly Bean, I hate the new ones they are so laggy and iPhone style... Thanks!!!
[Nexus S Themes and Apps] grotesque02:
With nova launcher prime you can!
[Nexus S Themes and Apps] martinaif:
Thanks! But I like the default launcher, its just the animations what bothers me... so if there is any chance of getting a flasheable fix it would be great...
[Nexus S Themes and Apps] grotesque02:
Try nova, the design is the same of default launcher!
[Nexus S Themes and Apps] explorer-10:
OR, if you want, you can try Holo Launcher/Holo Launcher Plus

A nice and simple ICS/JB launcher replacement alternative to Nova/Apex that works on 2.2+, up to JB
[Nexus S Themes and Apps] mixtapes08:
Try this one and report back...

just flash in recovery
[Nexus S Themes and Apps] martinaif:
Thank you so much!!! Testing right now... un a few minutes give you my feedback!
[Nexus S Themes and Apps] martinaif:
Well.. at the begining works perfectly but now the phone randomly reboot, i'm on stock 4.1.1 could you solve it? Or make a undo ICS animations? Because of the thrill of testing it i forget to make a backup... sorry for my bad english.
[Nexus S Themes and Apps] martinaif:
More information, is not that randomly, being more especific it's when i open some apps... and now without doing anything the jelly bean animations are back...

Still waiting for a solution thanks!!!!
[Nexus S Themes and Apps] martinaif:
Solved!! I get the backup of framework-res.apk inside the folder vrtheme-backup so i replaced yours (the one with ICS animations) whit my backuped one (the original JB) changing the permissions and voila!! No more reboots!! anyway i still want this mod, so if anybody can do it i will most than thankfull
[Nexus S Themes and Apps] lurtis:
Stock ROM you say... its prolly not deodexed. Most if not all mods will rarely work on an odexed ROM.
[Nexus S Themes and Apps] mixtapes08:
Try uploading a stock ics framework and i'll make you one again.. The files included in my zip is from a custom deodexed rom...

Sent from my Nexus S™
[Nexus S Themes and Apps] martinaif:
Ok.. Now i'm on a Jelly Belly 0.1.5.1 ROM, i'ts much better that the stock one, but as i was saying i really miss the old animations, taking into account that i have a deodexed ROM could you make a flasheable Zip with the animations that are on the Framework-res.apk i have attached below???

That Framework belongs to Passion v13.1 (ICS) Rom for Samsung Vibrant, that was my previous phone and it has the animations i like

One weird thing that i noticed is that the JB Framework has several "anim" folders, like anim, anim-land, anim-port, animator and anim720p, while the ICS has only two, anim and animator... anyway i'm just a newbie and there is a thousands of things that i don't understand, that's why ask you guys.

Thank you so much for your time, i'm so glad to get your answers....
[Nexus S Themes and Apps] mixtapes08:
Now your on jelly belly try my zip again

Sent from my Nexus S™
[Nexus S Themes and Apps] martinaif:
Bad news.... same result, it reboots after every opening app... any ideas?
[Nexus S Themes and Apps] martinaif:
More precisely when submenus or options menús pop up. And the animations aren't the same as the framework that i have attached...

I really don't want to bother you, so if you can do it that would be great and it you don't it's ok anyway, thanks thanks thanks..
[Nexus S Themes and Apps] martinaif:
How can I replace the Jelly Belly's for the ICS's.... I have tried sveral times and just replacing it didn't work, it reboots when you open a dialog or some submenues.... Please!!!!! Thanksssss

Hello guys,i am a complete novice to dell and have a dell streak 5 that is running android version

2.2.2

base band version GAUSB1A135100-EU.

kernel version

2.6.32.9-dj_steve-BFS-CFQ-KGSL2D-Vol-OC

oem version

190

build number

StreakDroid 1.9.0 from a DJ steve (on device when i purchased) and has basically ground to a Holt

I do not have much of an idea but i know that it needs updating.having read the forums about the updates my head is all over the place.

i ask please for a link to the correct firmware i need to flash.. and what i need to flash with the easiest way

Hope you can help me and point me in the right direction..I have took the time to read the forums but i still have no idea what i need for this device

as i have just received it.

Many many thanks in advance
[Streak 5 Q&A, Help & Troubleshooting] Strephon Alkhalikoi:
Rather open-ended question because the correct firmware is going to vary depending on what you want to do. For instance, do you wish to revert to a stock ROM? Do you want to be as up to date as possible? Are certain features important to you?

I personally don't recommend going back to stock, but to go forward and get a custom gingerbread ROM. Check the development forum for four good ones: Longhorn 2.9.1, DSC 1.2, Cyanogenmod 7, and MIUI.
[Streak 5 Q&A, Help & Troubleshooting] sas007:
Hi and thanks for taking time to reply,I am going to go back to stock to keep it as simple as possible to move device on,if its running stock there can be no hassles for new owner,i have the dell stock gingerbread update.

I will do a factory reset prior to flash and then put update on root of sd then boot to recovery and install IS THAT CORRECT?

many thanks
[Streak 5 Q&A, Help & Troubleshooting] deysmacro:
no need to revert to stock then... streakdroid 1.9 is the best for 2.2.2... so whats the point on going back to stock...? all stock are not optimized at all and have many hidden and useless application in it...

last time i tried using the deodexed stock but still it is not enough and does drain the battery too... custom rom is way better...

but if you insist on going stock.. i am not stopping you.. do what ever you want.. also updating to stock gingerbread such as olleh 407 has its own problem too...
[Streak 5 Q&A, Help & Troubleshooting] sas007:
Thanks for your help...if possible could you point me to the correct1.9 as i have no clue as so many roms and how do i apply it..I have read the threads and i am dizzy and to what i have to do as i have never been near a dell streak,never even knew they existed

so i will take that advice as i know your right i just thought stock would be easy to apply less hassle as i just want to get device up and running and stable.

again thank you for your help

[Streak 5 Q&A, Help & Troubleshooting] Strephon Alkhalikoi:
I see from other posts that you are going to put 407 on the device and with this post why you're going that route is clear. Factory reset isn't required prior to flashing because flashing the ROM itself will wipe everything. What is required is that the stock recovery image for 407 be placed on the device before attempting to flash the ROM. Otherwise it won't work. I'm not going to go into detail on how to change the recovery image because there are sticky posts galore that have all the relevant info. A good thread to look at is in Streak 5 Android Development, titled "Everything you always wanted to know about the Streak but were too busy bricking it".
[Streak 5 Q&A, Help & Troubleshooting] sas007:
Hi mate thank you for your kind help,yes I have the stock recovery to flash first.the download contained both recovery and rom image.

I think I am about there with what to do...flash recovery with flashboot then boot to that recovery and install firmware from sd card having changed to update 'what I am still a little perplexed about is the region I think the firmware is 00,what do I need for U.K.

Thankyou again
