[REQ] Please fix autofocus - kernel/soft developers - EVO 4G Q&A, Help & Troubleshooting

The current autofocus/manual focus for camera shots are abysmal. My old TP2 was doing autofocus much better (it would focus very well immediately).
On the evo, I have to touch the screen multiple times to force focus, until I'm satisfied with the result. There should be a better way to do autofocus that actually gives a sharper image.
It's as if focusing is rushed with the current software, and the end result is not so good.
Thanks.

Mine will usually focus just fine, but sometimes it will keep trying to focus and never lock

If you are going to fix auto focus, please fix the LED lighting. Seems in a dark room that the flash tends to be way to bright and wash out the picuture.

How about instead of an "improved" auto-focus, we just get some kinda slider adjustment for manual focus? Personally, I'd much rather see that.

i second this
oh and to the guy that was talking about the led flash, if you know your going to be using the led flash set the brightness in the camera app all the way down, it helps a lot

The manual focus slider is probably not gunna happen. We looked at it on the Nexus and it didn't look good.
I do agree though, tap-to-focus isn't near as good on the Evo as it is on the Nexus Desire ROMs. The Nexus autofocus is actually much better in general.

It's a shame that the camera on this phone had some corners cut so it would look better on paper. I'd much rather have a 5mp camera with better auto focus. And the video compression is terrible.

whoops wrong thread

Turning the brightness down does help, but would be better if the camera did some time of light metering prior to taking the picture and use the low led setting if needed, instead of lighting up the room. Using an elephant gun when a bb gun is needed approach is hard to deal with.

[Q] Camera on HTC HD7 Quality poor ?

I would like to here your views on the picture quality on HTC HD7
I think it is very poor compared to my HTC HD2 running Android
The focus is very bad is it just mine or is it a general problem ?
Steve
Indoor the camera seems to be iffy on quality but outdoor I haven't had an issue. It does seem that sometimes the camera doesn't want to focus but I think thats a bug.
This is one thing I hate about my HD7. Although I am not a camera guy, I still want the best out of the things I buy. I hope its just software issues, although I genuinely doubt it.
It's HTC, what did you expect? If anything they're known for their crap cameras.
On all the htc devices I have had (which is many), cameras have never been more than adequate. The camera on my hd7 is ok, better outdoors than in.
I can confirm this, I was at a bar with a friend whom have an HD2 running Haret. We both shoot the same object and the HD2 is so much more focused and sharp. the differences are huge.
considering what I use a phone camera for (twitter, facebook, quick pic messages), I consider it to be ok.
here are some taken last week:
edit: and those are default settings, haven't even played with the settings yet.
OMG, what are you eating on the last picture?
So-so
Yeah, its okay, nothing to write home about.
Inside photos can be a bit grainy, and it takes a while to focus.
But even so if you get use to it and take your time to take a photo (nothing ridiculous a few seconds more than usual) it produces decent pictures.
First photo is sharp.. although perhaps the young lady is moving a bit for the shutter...
Second photo is out of focus.
Third photo is also sharp.. and LOOKS DELCIOUS ! Now I'm hungry. sheesh...
Poor! Poor! Poor!
I always go into settings and force it to flash when taking a picture. This seems to cut down on the blurriness I usually get.
I've found workarounds for a lot of scenarios. It requires adjusting but the camera CAN take pretty damn good pictures. I've never seen a phone that has a GREAT camera though, so I don't know why people ***** so much.

What are the workarounds you found?
well i have had an iphone 4 and now i'm on hd7..i must admit the iphone 4 is better in the camera department (even though hd7 has the same res) the camera is fine in day time but in low light conditions...it suffers & can't focus...
i hope they will fix it...
I agree with what most people have said. In good lighting conditions, the camera is good... However bring in the low-level conditions and the shutter speed is greatly reduced causing motion blur a focusing issues.
Some "Artsy" pics i've take in good lighting conditions attached, which i think are respectable for a HTC camera.

Show me a camera that doesn't reduce the shutter speed in low light and I'll introduce you to Santa Claus. That's how cameras work. The less light there is, the longer the shutter has to remain open to get enough light to stimulate the CCD.
Elementary physics.
All you people with focussing issues, you need to half-press the button to focus, then depress all the way to take the shot. Just like any digital camera.
I've not had any issues with focussing myself.

I'm aware of how camera's work
Show me a camera/phone 5MP or more that has a shutter speed as slow or slower than that on the HTC's.
Now i don't know enough about how HTC develop their Camera's or the software for them but to me it seems all HTC's have a poor Auto-Brightness filter. It stems back to my old TyTN II where putting the phone on standby and then back on again would disable the auto-brightness, thus massively increasing FPS and shutter speed in the camera, at the cost of having a rediculously dark photo/video.
The Quality is there, It's just making best use of it that seems to be difficult.
I think it's pretty good tbh, as long as you half-press first. I haven't had any of the issues others have reported such as the quality or pinkish hue (knock on wood). For me, it's been more than enough... But that may vary with uses and expectations... I've always understood that it's a phone camera... Not a personal Nikon.

The correct shutter speed is determined by the sensitivity of the CCD and the size of the aperture. Camera phones have a tiny aperture and probably quite an insensitive CCD so the shutter speed is always going to have to be quite slow to compensate.

Not sure what you mean by "auto-brightness filter" - cameras employ a process called "metering" to determine if a scene is over or underexposed, and metering can be done across the frame as a whole or just over a particular spot, say in the middle of the frame. If your shots are suffering from poor metering, i.e. the phone doesn't set the correct shutter speed for the scene, then you need to change the metering type. Phones don't have a very high dynamic range either, so they have trouble with scenes containing both very bright and very dark patches.
Basically, phone cameras really are not suited to anything but the most casual of photos when you don't have a proper camera to hand.
But even a phone camera can produce vaguely acceptable results if you learn the basics of photography and work with the limitations. With no control over aperture, ISO or shutter speed, and with such a microscopic lense, it'll always be a huge compromise though.
I don't know why people get so upset about the cameras on their phones - they were never meant to replace a real camera, they're just a toy.

[Q] Night photography problem?

I really dislike this phone for the night shots, whenever there is some sort of light in the shot, it REALLY ruins the picture because it just becomes a big bright spot. Do you guys have the same problem?
Pictures attached!
Also, not only when its super dark, and these are EXTREMELY bright lights, they're very normal lights...
1 more picture attached!
It's probably just because of the fact that in order to get a nice shot in low light, the exposure needs to be slightly longer. Same with basically any other camera. If the exposure wasn't long enough, then the lights wouldn't be big bright spots, but the whole picture would be a fair bit darker.
You could try going into the camera settings and bumping the exposure down a bit and see if it helps...
I actually do a comparison with an iPhone 4 side by side and the picture is similarly bright, but the light doesn't dominate the picture like it does in these.
In any case, if I have to adjust the exposure on all my shots, I'd think that's a serious shortcoming of the sgs3
No offense.... but wow can people be seriously nit-picky. That's like saying that it's a serious shortcoming of owning a DSLR if you have to adjust exposure, aperture, and ISO settings to get a good low-light shot without using the flash and without having certain bits being overly bright. To be honest, i think that the idea of being ABLE to adjust the exposure to try to get a nicer shot is a serious BENEFIT of the SGS3. Last i checked... on the iPhone, all you really have is the button to take the picture.... and not much else.
Make sure there are NO FINGER SMUGES on the back plastic lens it make a huge difference. I also use a different camera app like ProCapture that has more "manual" features

Photos seem dark?

Don't know if it's just me. ... But last night I used the camera for the first time and while I was setting up the shot and focusing the colours looked great. .. nice and bright. .
But when I took the shot and viewed it back it looked really washed out and dim. Here's a quick pic I took last night in a relatively well lit room
All settings were standard and auto Flash. .
Am I doing something wrong?

No, you are doing nothing wrong. That's how the camera behaves. And just turn off light and use flash to take the shot, you will also see how weak is the flash. Sorry to say, the camera is a downgrade for me coming from a SII. Now some people will say it takes great photos in outdoor with bright sunlight, well, even my mom's 5 year old Nokia which has a VGA camera will take good photos in same situation.
In short, the camera is below standard.
And, you need to use preset 'low light' for brighter photos, but you should keep your hands still.

It so happens that I own the S2, S3 and now the Note 2.
It is definitely not a downgrade from the S2. The detail is sometimes better on the S2 that is true, but the field of view is better on S3/N2 and the color quality as well as photos in the dark (with the new lowlight option) are better by far.
Turn ON the Auto Contrast in the settings,unfortunately you have to do the same over and over again everytime you start the Camera Application.

Do I have a faulty camera?

Is it just me and I happen to have a faulty camera, or does the camera still sorta suck?
I mean, don't get me wrong, the pictures are sharper than ever due to the bump in megapixels, but from my experience, I can't get too close to a subject, or else the camera just won't focus. I have to pull back slightly to get a good macro shot. Not only that, but usually when you're in a dark room with a single light source, you have to tap on the light in order for the exposure to adjust to the light so you can get a clear picture. With my phone, its actually the opposite. You have to tap on a dark spot in order for the exposure to adjust to the light source. If you tap on the light source, then the exposure gets blown WAYYYYY TF (the ****) out. It's... Actually kinda weird.
Maybe I'm not camering right or something. Or maybe this is something that can be fixed in a future update and/or a different camera app. I will admit though, however, that before I got my N5X, I was using my Galaxy S6 for about a week, so I might have been slightly spoiled by that, lol.

Which camera app are you using? Exposure works as expected and not how you describe in Google Camera for me.

Note 10+ camera - smeared looking photos

Is anyone having camera issues?
For whatever reason, when I try to take a photo of my dog, the face looks smeared. Roughly 80-90% of the time. While on my iphone it looks great...I'm kinda bummed out about this and wondering if this is either an issue with my unit, or if this is a common thing with Samsung.
Also, just for some more info, I've tried turning on/off hdr, scene optimizer, and whenever I am ready to take a picture, it looks stunning. Then I hit the shutter button, and it turns out like poop. Barely half the quality of what it looked like before I hit the shutter button.
Here are two pics to compare so you can see what I mean. If anyone has any info regarding this please let me know, thanks.

I have always seen this happen on Samsung phones (S8, S9, and S10) when taking pictures in certain lighting situations. Especially inside when taking pictures of a rug or anything slightly fluffy. It is as if it is trying to apply the beauty mode to everything.
Try to get the AF to lock on to the animal's eyes.
A good pro cam can most times; it's a small but high contrast target.
-If you don't grab the eye(s) you lose the shot-
I haven't done any research how this cam's AF works; normally you would point focus AF although it may still target the hair as it's a high contrast target too.
There are a lot of high contrast targets in this shot, the dog's nose, that chair, the dog's hair and the floor boards. Try to limit potential AF targets by keeping the composure simpler and less cluttered with high contrast targets if you intend on capturing a face with the eyes in focus.
Getting closer to the subject makes an AF lock on the eye more likely. Try punching up the yellow focus/tracking square.
Worse with this cam's large aperture it makes for a shallow DOF which means a spot on focus is needed. The aperture setting is fixed so you can't stop it down to something reasonable like f/5.6 however this cam is sharpest at it's fixed aperture. Backing up therefore may help get more of the subject in focus. You need to learn to see through the camera's eye, as it sees rather than your eyes.
It is much more limited than the superb human visual system...
Manual focus is sometimes the only sure fire way to do it. In the pro mode it does have manual focus but lacks the smooth ring control of a good piece of glass found on stand alone cam systems.
A trade off... it's only a smartphone.
First, nice looking dog.
A couple of questions.
What were the lighting conditions?
Was your dog moving?

Samsung applies way to much noise reduction destroying the details of a photo. This is why it appears like that. Also, there's nasty shutter lag with the stock cam...so you press the shutter to take the pic but it doesn't happen right away simply because hdr is always on no matter if you have the switch off or not. Basically Samsung have rendered there stock camera useless. Get the latest GCam port from arnova....all problems solved.
