Is the front video supposed to have really low exposure? - ZTE Axon 7 Questions & Answers

For some reason the exposure on the front camera is really low. When switching back and forth from selfie mode and video mode there is a huge drop in exposure, compared to the front camera where there isn't any difference at all. Looking at all the video tests for the front camera on youtube, they all look fine in comparison. I can't tell if this is a hardware defect or if the front video camera on the axon 7 isn't that great. Anybody else have this issue?

Hi, I have the same problem at low light but it's fine at good light condition. It seems that the back camera automatically adjusts the exposure at low light, but the font camera does a bad job. However, you can manually adjust the exposure thorough the vertical slider on the right. The algorithm of Axon 7's camera sucks!

Camera Frames

When i try to film, at night..in my own room using only one light bulb it's filming in frames, and that's pretty nasty. Anyoane else got the same problem? Maybe i'll put a link tonight...
the video camera on the dvp is pretty horrible. I found that fiddling with the camera settings in still shoot mode before switching over to the video camera helps slightly, as well as shooting in a lower resolution.
Uhm, thats how cameras work. The darker the surrounding area the more light the camera/shutter has to let in. EVERY camera has this problem because they aren't as sensative as your eyes.
The iphone 4 camera works great...is filming like a real cam

Bad camera focus

So, my problem is that my camera does not seem to focus an Objekt, even when I "touch " it in the camera app. It is still a bit blurry when I view the taken shot. When I look at my friends Nexus 4, colors are much better and everything is sharp. Is it possible that I have a broken camera? The settings are exactly the same...
It may be helpful to post some example shots.
1st thing to look for is to make sure that the glass covering the lens is clean. And shoot in good lighting.
Known problem, please star the issue http://code.google.com/p/android/issues/detail?id=43153&thanks=43153&ts=1359017856
AW: Bad camera focus
And the washed out colors? Max it be the fault of rev10 devices? A friend of mine said something like that
//edit
Here's a sample. If you zomm in you will see the Blurry borders. They are really annoying because when I look at the pic on a PC, I am able to notice it. Maybe it's the cameras fault or Googles fault for bad drivers and software.

It seems to me like the hardware is perfectly capable of the focal lengths to get clear focus, it's just the autofocus implementation that's broken. Is autofocus a driver level implementation? If so, would it be feasible to try and create a custom driver to at least allow for true manual focus?
There are several things that can be going on here. 1.) it ain't a great lens, so not all areas of the picture are going to be razor sharp. I see a good degree of softness in the corners.
2.) I have noticed the camera's default behavior is to use lower ISO, and longer shutter speeds in less than ideal light, making camera movement a major factor in blurry photos. If you're gonna test under less than ideal light, rig up some kind of tripod.
3.) Auto-focus algorithms decide focus based on maximum contrast. If the area of your focus reticle is over an area that has poor contrast, focus will be compromised. Low light also lowers contrast.
4.) Depth of field. It is limited with this lens. Make sure areas you are checking for focus are on/near the same plane with shots that have reasonable distance separating foreground/background objects. They all can't be in focus.
With all that said, reasonable photography skills can get pretty reasonable results from this camera, as is exhibited in the photos posted in the photo thread of the "general" forum.
It does focus, but has a small delay tho..
actually the focus on N4 is slow a little bit ..
Is there any new piece of information about the bad camera focus?
anyone else have a pink haze when capturing white objects

Front Facing camera

Hey!
I can't seem to find any samples or anyone even showing or mentioning the results of the front facing camera in any review.. From what I have seen on the z1 is that the pictures of the front facing camera are grainy like crazy if the light isn't perfect. Anyone knows if the slightly better hardware of the z2 camera gives out a better end result? Maybe anyone of you can link to some pictures on the web.
Thanks!
The front camera is just a 2mp ish camera which really all you want it for is 'selfies' which it will do the job.
From the samples I have seen Im pretty pleased with the results of the rear camera and low light pictures definately look acceptable.
Im on the LG G2 now and the camera is awesome, the pictures I take are amazing, until the light starts to fade, then it takes about 3 seconds to focus, if the object is moving its blurry and looks like a cartoon. Im just hoping the Z2 gives me the awesome pictures in daylight and ok pictures in low light which are not blured, that will do me. But as always I wont know until I test under my own uniqe conditions.

[Q] Front facing camera and low light compensation

Hello,
I'm a heavy user of Glide and I get really annoyed by how the Samsung Note 4 front-facing camera performs. It seems that Samsung implemented low light compensation which makes any head or hands movement look ghostly. I'm deaf so use sign language over Glide video to my friends and my hands blur easily when using front camera.
Is there a way to turn off the low light compensation or does anyone know the proper channels for me to go through with Samsung to ask them to, at least, add this as an option.
Thanks,
Jared
i'm quite disappointed with the front facing camera as well. on paper a 3.7 mpx front facing camera with "wide angle lens" should appeal
to most people, myself included. i've found that the front facing camera has lots of ghosting, choppy and partly blurry movement.
this is only confined to the normal selfie mode on my phone though. i have tested out the wide angle selfe mode, and that one seem to
work fine, with smooth and decent motion and movement. most people haven't complained about this, but i'm definitely bothered by it.

Can you use the wide angle (back) camera to take selfies?

Hi all - it sounds like the front (selfie) camera does not take the best pics.
One of the uses I wanted for the G6 is to use the back camera (the wide angle one) to take selfies instead.
I won't be able to see the screen, but with the wide angle lens, I don't really need to do much framing I'm guessing.
The only thing that I'm concerned about is the lack of auto focus and if the wide angle camera can focus on subjects about 1 metre away from them.
Does anyone have a G6 who could comment / or post a sample pic of this? This is pretty much the dealbreaker for me to get this phone.
Cheers!
I'm interested in the same question! Would be great if anyone could comment on this, hence bumping this thread.
Yes. Front facing camera is not as good as it should be. Specially in low light situation...
This, and lack of LED notification light are the biggest flaw to me
Back cameras takes good selfies though. I don't have any problem with framing or autofocus. Does a good job with defocusing background and shaking effect is at minimum thanks to new image stabilizing system.
Hope this help you
Cheers
Someone here at xda calculated that all things between 35cm and infinity are in Focus for the wide angle camera.
I also made some tests and I think that he is not totaly wrong with his 35cm.
So taking selfies should be ok.
