Nexus 4 Flash Photography problems

A request to the people who've already got their nexus 4!
Can you take some pictures in-doors in relatively ****ty light conditions? I want to see how your flash works.
When taking pictures with flash on I've noticed that the ISO the phone uses is very high.. 800? It's like the phone does not know its using the flash.
I have taken some pics with my old HTC wildfire s and the nexus 4 to compare them - here are the results:
LINKS DEAD
Can someone please take some flash photos from up-close with their nexus 4 for a comparison?
Thanks!

Links died, please see the photos attached!

I can take some sample pics later but I have noticed the flash blowing out pictures when in marginal lighting conditions (indoors+early morning+no overhead lighting) to the point that I'm better off turning the flash off because the camera does a much better job without it.
And at night I've been opting for HDR.

You can see here how the woodgrain gets blown out, I'll post more pics as I take them.

For comparison here is the same shot with no flash.

This will happen with any camera that is used right up close like that.
Another stupid thread trying to find problems.

It doesn't happen with my sensation or pm1, so it doesn't happen with every camera and I just did an upclose shot to demonstrate.
I had to go through my pictures but I found some that show the same issue and a completely different issue when using the flash. I'm sure these things will be fixed with software but flash photography is certainly not the n4's strong suit, although I do find low light photography to be pretty good.

have you even seen the pictures from the original post? They were taken with two different mobile phone cameras, both with FLASH ON!

Maybe the nexus 4 flash is just more powerful than the flashes you used previously.

That isn't how flashes should work, the software should do a bit of metering and then limit output for the situation it seems that this isn't happening correctly (it is happening because the N4 will flash before the picture is taken) which is why I think it will be fixed in a software update.

i think its bug with camera driver

Has anyone tried after todays update?

If you don't like it why bother to comment? Lol,
I have found the flash being too strong a bit of a frustration it's not a deal breaker but it is something they could sort, thankfully it can still take reasonable shots without the flash in many lighting situations.

Does the Nexus 4 really have a flash or is it just a light that comes on and stays on when in camera mode with flash selected. I mean is the light off and then flash on when the shutter is activated?

As mentioned, I find HDR helps a lot in low light. It does use the flash, but I am not sure if it is for the shot or for pre-shot metering.

It's a regular flash that comes on as needed. Stays on only for video.
Oh yea, it does sometimes stay lit for longer than I would have thought for HDR. But I think that is a plus that it can even use flash in HDR mode (my iPhone doesn't).

Yes it pre lights the subject to meter and then flashes again when the picture is taken.

You guys can always try different apps. I used zoom in think it s called on my i9001 s plus.

Yes, the flash feels definitely a bit wonky compared to my S3. I also find that sometimes even after I touch to focus, it refocuses and takes a blurry picture anyways. That and because the touch screen is less sensitive than I'm used to, I usually miss the shutter button the first time and end up pressing harder and shaking/moving the camera the second time.

I'll try to replicate your flash shots but looking at out of the box first shots in auto WB i can tell that either the sensor, optics, software or combination of all three result in pathetic images for a flagship camera. My 3mp samsung produces better pictures. Will try to post some pictures tomorrow.

Camera sometimes blurry?!

Hey guys,
i own my One for a couple of days now and I'm a bit unsure if the cam is really okay.
I'm on 1.29 and some pictures are really blurry on different areas, but then again the same camera shot is completely okay and sharp.
Here are examples of what I meant.
The first two pictures were taken from the same location and you'll see the difference (besides the sky is not in line in one of them).
The third one is really blurry on the right side but this can't be a out of focus thing because of the small sensor and wide angle.
The other pictures I made were completely fine so far.
Is this a known issue? How can I test the camera better? Do I need a replacement?
Thanks
Daniel

Maybe a better example from a couple of minutes ago.
I did the same shot a couple of times and here is the difference (this is a crop from the left side of the picture)

Mine does the same thing I don't know why...

The distortion seems to indicate a problem with the rolling shutter, along with movement in the camera. I'd hazard a guess and say your hand was moving slightly when the first picture was taken. The effect shouldn't be that pronounced, though, you shouldn't even been able to see it, really.
I haven't even figured out which way the shutter moves on this one.. hm. Something to look at.

I'm not sure if i understood you right but the Shutter time was 1/1200 so i don't think that shaking should be a problem.
Also it's only partial, as you see the house is perfectly sharp!

Yeah, but CMOS sensors don't capture the image all at once. It's like a scanline renderer or an old CRT television, it starts at the top and works its way down to the bottom. That's what creates the "warping" effect on videos shot with cameras like this (you can Google it, it's typically called the "rolling shutter effect"). If you switch between the two photos you posted, there's clearly some pretty nasty distortion happening on one of them (probably the first one, with the blurring).
But, the bottom line is that you shouldn't see it at all, or it should be so slight as to be unnoticeable on a still frame shot. I've seen it on videos I've taken with my older phones, but never on a still shot, and never as bad as what I see in those shots you posted. I'm not sure if that's a problem in the software/firmware of the camera (in which case it can be fixed), or a problem with the CMOS sensor itself not actually capturing the image as quickly as it was supposed to.
Was there anything particular about these shots that was different from the norm? Were they captured in a batch, or just a single click? ZOE mode, or just straight up? The stock HTC camera app, or a third-party app? And is the phone ROMd? I don't think they've got the camera working quite right in most ROMs right now, although I don't know if the effect would be what you're describing.
Mind you, I don't know squat about actually fixing the issue, but I can hopefully help narrow it down to what's causing it.
Curse my not-having-the-phone-yet-edness. I'd test all this myself, but my One doesn't get here until tomorrow. I do intend on running the camera through its paces over the first week or so I have it, though.

same here
I have the same problem sometimes..

Thanks for your explaination. I also heard that the OIS may cause this.
And as there are a couple of people with the same issue (in this thread and over the net) maybe other users haven't experienced it YET and it's a software issue. I'm really quite unsure what to do.
The shots were taken with the original Camera app, without Zoe, with original non-rooted firmware, with normal automatic settings.
I've experienced this about 4 times now and i shot about 30-40 Pictures so far.

I've also had the problem a few times, and outdoors in daylight where shutter speed should be so fast add to negate slight hand movement. Also the blur will sometimes be in only half the picture... Odd.

Have you tried to focus twice . It seems to fix my problem.

Yes, because i remember one blurry picture i made - I focussed once and it was extreme blurry on the screen, then i focussed twice and the picture was okay on the camera screen, but in the end it was blurry...

camera defect
I had the same issue with the camera. .. I spoke with htc advisors and they told me that is hardware problem(lense or focus). If you have problem try to take a video and look if it's all ok.. my was keep focusing on the right hand side every few seconds. ...so I send my phone back to them for repair.. waiting now ..

Tried it and got nicely colored but kinda blurry pictures.

it is not a Camera bug. if you bother to check the picture quality taken with other Xperia phones you will notice the same thing too. In fact, this extra yellow tinge goes all the way back to Sony Ericsson Cybershot K800, which was the first Cybershot phone I owned. I have no idea whether it is just a coincidence or whether it is inherent in Sony digital camera processing system.

Xperia Z camera flash not working?

I'm trying to take pictures in darker areas but the flash doesn't seem to work? It will flash, but the picture won't come out with lighting, it remains dark.
My friends iPhone takes pictures just fine in dark areas. Is this an android issue or phone issue or what?

Are you using a modified camera app?

it might be ur issue
go to camera setting and set flash to auto
:good:

Meh, I'm a noob. It's not a flash issue, it's a low light issue. I just realized that and was able to search through the forums about it. Need to change settings/use different camera app.

Is it true the front facing camera lags

I've read a report saying the front facing camera lags behind, can somebody confirm this?!

Yes, its happening to me too, but not happen every time.

Have you determined what conditions cause this to happen?
Sent from my XT1058 using XDA Free mobile app

Not yet, probably is related to the type of lighting environment.

Hey man!! I bought this phone today and I'm very disappointed because the front camera is lagging as ****! Dammit!!
I do not pretend to return it to Motorola so I'll assume that this will be fixes as soon as they send an update.
Overall the phone is very good, nothing special (if you had the previous moto x you don't HAVE to buy the new one)

I think I asked you in another thread, but I'll post it here: have you tried the Google Camera? it could be a camera app issue
edit: if you're not in a well lit area, the front camera can lag. that's what I read from a user with the same problem. he went into a store with a lot of lights and it worked fine

That is correct I posted on that other topic too. So, even in a lighter place the camera still sucks. That is very very sad. I'm not a selfie addicted but the front camera is a very useful resource

When I get mine, I'll test it. Maybe the U.S. version would be fixed. I'm only speculating

I never use the front camera unless I'm using it as a mirror. I just took a bunch of selfies in a dark room and noticed no lag. Did the same thing with my 2013 and my N5, which was the slower of the three.

Pure version is lag as well. I never do a selfie so I don't care.

No lag. On the front camera.

Yeah definitely lags significantly

there is a lot of lag for the FFC. but the lag disappears when you hit the record button if you want video. idk what the heck is happening lol. it isn't a deal breaker

Definitely lags.... Pure edition

Definitely have lag here too. Didn't earlier in the day in sunlight.

No noticeable lag on my front-facing camera.

Use it in low light.

It is definitely in low light. I can stick it under my table, observe the lag, and then point it at my properly-lighted face and not have an issue.
Should be something easily fixed with an update, pretty weird though.

Mad lag
Laggin like a motha inside (lower light) worked well outside

Noticed when it doesn't try to correct for the lighting the lag is gone. Mine was lagging once and adjusted back to normal balance and the lag disappeared until it tried to light up my face a bit.
