Voodoo screen fix - Epic 4G Q&A, Help & Troubleshooting

I see that Voodoo sound is being implemented left and right... but what about the screen? Our device would benefit more from the screen than the sound, IMO.

If the voodoo sound is as good as it is supposed to be, awesome... as far as screen is that a video settings app??? I would really love a full suite of vid settings, including gamma etc... if I can feasibly watch movies I wanna ISF calibrate the display, one: because im retentive that way, and two: see what this bad boy can do with proper calibration...

Although it looked washed out (but super bright), I'm curious what BThomas did in his Epic ROM that altered the color. His was the first that I saw that had voodoo in there.

[Q] Sound Settings/EQ

Happy owner of a Focus here:
Just have a quick question regarding sound settings or an equalizer of some sort in WP7 - unfortunately I think I have the answer after a brief search. Is there no way to at least bump up the bass settings? When listening to music, sound comes out a little "low" for my tastes (but not unacceptable). When watching video however, the sound comes out really low, even when maxed out.
Can anyone confirm there's no way to adjust this in WP7 settings?

Yeah, HTC have an app where you can do that so either we need to wait for an app (don't know if that would happen as HTC would get special access to the phone probably)
Interesting... I guess it's more likely that MS or Samsung would put something out?
yea only for HTC devices.. like when u open market using a htc you would see HTC apps.. eq its there.. does help on my hd7...a lot...but hey u have a lot more features/settings to play on your camera than i do.. hd7 is very limited .

What exactly is Voodoo Sound/Color?

I keep seeing people wanting Voodoo Sound or Voodoo Color and I don't know what it is? Could someone explain it to me? And why people would want it? I want to know how much better it makes our Epics by having them. Thanks!

Voodoo sound is kind of like an audio enhancer..bass and volume booster hifi sound quality etc. Voodoo color allows you to change the deepness of colors and shadows. As well as tune the rgbs and change the color warmth and coolness basically tuning an lcd tv for your phone

Voodoo lets you enhance your phones display/audio features by making whites whiter and darks darker. It also lets you enhance your phones audio for listening to music. Do a search around the forum, you will find more in depth info.

Adjust contrast?

Hi,
I like my Nexus, but it has one flaw that really bothers me: when playing videos, dark scenes look absolutely horrible. The blacks are grainy and the colors look washed out. It's a step down from the first generation Nexus 7. Is there a kernel or ROM I can install that would let me adjust the contrast?

Are you sure the problem isn't on the video/file instead?
Try using another video player from the playstore?

[Q] Low display quality

Hi guys,
I have my Xperia Z1 Compact. The smartphone is advertised(and reviewed!) as having very good display quality. However I cannot agree with that. My previous phone was Iphone 4s(so 2-3 years older smartphone) and while I really loved android as a system(it has its drawbacks though) I can't say that I loved sony's display.The quality is low. I can't even call it average. Much worse than Iphone 4s' display. There are four main problems that I noticed:
1) Unrealistic colours - the most annoying problem. Tanned skin look orange or red so any photos from beach will look like basket with tomatos. Just check the picture on polish wikipedia of politician 'Janusz Palikot' and see the difference.
2) Any details completely missed in a shadow. Just watch the beggining of the video on youtube called "7. bronn the commander"
and see difference between Z1compact and 4s(or your computer):
3) viewed images quality in applications like facebook are much lower than in real(or on Iphone). When I view a picture in facebook it seem to be less sharp than if I download the picture on computer, send it to e-mail and then download it from my e-mail to smartphone,
4) When i check gamma in app called "display tester" (option: gamma detection) the result is 1.4 while i read that it should have been 2.2. What's the reason?
What's the reason of those drawbacks(the third one is the least annoying but still) and how can I fix it? Is there any way to calibrate it(someone did that?) I use app "screen adjuster" but it's solve problems only partially and it's heals only symptoms not causes.
BTW White balance DOESN'T help.
PS. Sorry that I don't post the exact links but I am not allowed to I am attaching photos anyway
my dispaly is fine. It looks same on all Z1c's. Check the pictures I attached yourself. How is that possible that smartphone advertised as having top quality display works like this and cannot even display human skin properly? Iphone 4s i almost 3 years older but the display is FAR above sony's.
Anyway is there anything I can do to fix it?

Question Whats wrong with A52s auto white balance

I would like to hear some opinions on this. I noticed some time ago that my videos had very inconsistent colors - there would be visible change of the balance when paning around or filming different objects to an extent that seems odd. After trying out and comparing I did realise that the main camera tends to very aggresively change the auto white balance, even if the scene is basically the same and the phone just slightly changes angle. It seems as it tries to desperately match white balance to every frame and its content (forgive my amateur vocabulary here), which to me seems strange and looking at other phones they just hold a much more consistent balance.
I attach 2 videos to show the issue - keep in mind that the issue isnt as visible always, as I tried very specific scenes/angles to show it.
When I use manual white balance it works great, so it kinda feels like a software issue (?)
Does anybody have a similar experience?
Would you mind trying to film a video in a similar scenario, but after disabling the option "scene optimizer" in the camera settings? I don't know if it does anything, but might be worth trying.

Thanks for the tipp, I'll try to compare it, although I dont think that scene optimizer affects videos
Unfortunately turning scene optimizer off doesnt change it (video attached).
It still feels like a software issue, but since nobody has yet confirmed a similar experience I'm starting to think it might be a problem with my unit. (Btw my A52s seems to have the Samsung image sensor not the Sony one)
Edit: or, I am exaggerating and this behaviour is actually not unusual - havent had a Samsung phone for a few years before my A52s

I do not shoot a lot of video, but in the few videos I did shoot I never saw what is visible in your videos (Sony sensor). It is indeed very jarring. Do you only have it with footage of grass or just always?
In the Samsung camera app, you can go the "Professional Video" mode in the "More" section (so where macro etc. is), and then set whitebalance manually to e.g. 5500K and see whether it is more stable then. But like I said I do not shoot a lot of video, so I certainly do not have experience with that professional video mode.
Edit: I now see that you already mention manual whitebalance yourself. So are there disadvantages to just using professional video mode all the time then?

It definitely gets more visible in outside scenes, more so if there is a lot of green in the frame - indoors and with artificial light it definitely is hard to spot. As I mentioned above it feels like it tries to match the balance to the content or objects of/in the frame, instead of keeping a consistent balance. I had a video where I stuck my hand in and out of the frame and it would drastically change the whole color to match the hand it seemed (thinking about it, the background was grass also, so ...).
Pro mode is a solution, it's just that I'm not a fan of setting the balance everytime I take a video or photo - and the balance ofc affects photos in the same way, as 2 photos of basically the same scene might have drastically different WB.
Nevertheless thanks a lot for your input - I also very much enjoyed your detailed instructions for Gcam usage

You would not have to set it every time (probably). In the Samsung camera app I have dragged the Pro Photo (not video) mode to the 'main bar' (from the more menu you can hold and drag items in and out of the main bar for quick access), with a changed fixed ISO (for shooting of fast action scenes), and you set it once and the camera app will remember that setting forever. And I think for all outside scenes around 5600K WB will work fine (it's not like the A52s is a high quality video machine anyway).
I didn't want to bring up gcam because I had no idea whether that would make a difference, but now that you brought it up, does that have the same whitebalance issues for you (in video)?

I meant I would have to set it again for every scene, but you are right, something like 5600 would probably be okay for most outdoor stuff. And with rearranging the icons it wouldnt be such a hassle. I'll try that out for daily use, thanks!
I am using BSG gcam also, because I find the nightmode drastically better but unfortunately the balance issue is the same, so I guess the balance gets set on system level. I also tried gcam awb but it always seems to be a bit off no matter the config - but I prefer the stock app for daylight anyway (apart from the wb)
