Camera

Hi,
Is there any possibility to speed up the camera?

No.
Damn, why does this forum force me to make my message at least 10 characters long...?

Switch off the shutter sound.

Have you tried this,while you are in camera mode turn off the PDA wait for ten seconds and then turn it back on,you will notice that while the image is somewhat darker the framerate does not lag when you move the phone, its more noticeable when you are in a not very well lit room.

Actually what you mention works better when in camera mode you turn it off, cover the lens with your hand, then turn it on with your hand still covering the lens, wait a second or two then use the camera. while the image quality isn't as great because it's low light, frame rate is much faster. but the moment you point at some bright light, it resets again. kind of a lame hack but what are we gonna do...
if you're in a bright light situation, such as outdoors on a sunny day, frame rate is fine.

Try this from the Kaiser forum. It worked on older roms.

pink/white camera fix

I've had a problem off and on, sometimes the camera stops working and flashes pink and white instead of showing the preview image. (flash & other icons still remain on the screen--if you try to snap a photo it sometimes turns on the flash and keeps it on--sometimes a bright light such as light bulb or sun will sort of show up--restarting often does not help)
here is the problem: the shutter is not opening. It might be opening a little, but not all the way. You might hear it click.
Here is the (a) fix: smack your camera. Forwards or backwards, using the palm of your hand. Moderate strength.
If there is a more elegant fix, I'd like to hear.

might need to replace the camera it self. sounds like a hardware failure. :'(

Nexus 4 image persistence?

Alright, so I have a nexus 4. I don't know how long this issue has been around, since only now am I noticing it. After having a fairly high contrast image on the screen for a few seconds, such as the facebook status bar, if I go to another app or the homescreen, sometimes I can see a faint outline of the image. It can occasionally get really bad, especially after the screen has been off for a while. Like I was watching a video on firefox, so I switched to landscape mode. The video couldn't go full screen and I had two grey bars on the side. I was shocked to clearly see the firefox navbar burnt into my screen. Thankfully all of it cleared up, but I'm wondering if anyone else has an image persistence issue. I'll try and get a picture once I can find a camera with decent exposure. Also, it seems that the sides of the screen, especially the right side, are brighter than the rest of the screen, also after the screen has been off for a while. Don't know if the two issues are correlated or not, but I think they are. I was using facebook and my phone crashed with a white screen with lines going through it, awful image persistence, and terrible bleed through. Held down the power button and there was the bleed through and image persistence, along with screen flicker that makes a CRT look entirely static. I'm wondering, what the hell is up with my phone? I haven't really done anything wrong to it, this just kind of happened.

Got a photo. Couldn't find the cable to connect my camera to my computer, so I had to take a photo of a photo, and for that it turned out alright. Don't know how well it will turn out on different displays, but trust me it's there. This is the icon in the top right corner of the facebook application. When I swipe from the right to the left to see who's available for chat, I can see an outline of the icon that was there before.

I've noticed the persistence too at times, like a ghost image - CRT with a static image on too long, so if there was any doubt, it's not just you

I've had the same problem several times before. I just had it again, quite prominent! It stays for a few seconds, and then fades off to nothing.....Quite worried? :S

Flash darkens photos?

Anyone else observing that when they take a pic with the flash on in "medium" light conditions, the photo comes out actually darker than if the flash wasn't even used?
I swear the timing of the flash is bad on my S5. When I tap the button to shoot the photo, the flash turns on and the image on the screen looks bright and good. But then I think the photo is actually taken a split second later after the flash has turned off, and the photo that gets taken is dark as hell. I think I've tried all the combination of settings in the default S5 camera app, and nothing helps.

I haven't seen this with my S5. Unfortunately you didn't elaborate on your camera settings, camera version or other crucial details.
At a guess, and it is only speculation since we don't have your details, you are expecting the flash to act like a fill flash. When the auto mode (which is probably what you are using) probably uses the flash in a conventional manner i.e. a fixed shutter speed (or limited shutter speed range). There are good reasons for that, but the net effect if the subject is outside of the flash range is that little of the flash is reflected back and the (presumably) higher shutter speed lets less total light in resulting in a darker picture.
You can test that thesis by taking some pictures of a subject that is very close to the camera. If the problem goes away with close subjects that implies that the problem is an artifact of using flash for a subject that is too distant for the flash to work with. No flash can work at an unlimited distance which is why people using a flash in a stadium when they are 75 meters from a subject is silly. In this case, flash mode simply isn't appropriate to the situation you are using it in and you'd be farther ahead to use a slower shutter speed, without flash.
It's highly unlikely that a bug would see the shutter opening after the flash.
.

It happens with literally *every* combination of the settings in the camera app (with flash set to "on"). Auto mode, beauty face mode... actually, are there any other modes that I'd use to take a picture of something 3 feet away in a darkish room? I have panorama, "shot & more", virtual tour... those wouldn't be right, correct? So both beauty face and auto, with all the combination of settings... hdr on/off, stabilization on/off, iso at auto and all four "manual" options, all three metering modes... nothing makes a difference.
The problem is the same all the times -- it's not just that the non "subject" areas are dark -- the whole image is dark, just like if you turned off the light in a room and snapped a pic at the moment when the light was still on at 50% brightness as it's turning off. It's super annoying just because of how damn good the image looks on the screen when the photo is being taken... it even seems to "snap" the shot at the right time... the shutter sound goes off and the little border animation happens when the pic is nice and bright. Then I open the actual image and it's garbage.
I was hoping someone might know of some setting in a config file somewhere for a delay between when the flash is triggered and when the camera attempts to capture the image, and that maybe mine got changed somehow to a larger than optimal value.
My wife has an s5, I'll have to test with hers and see if it suffers from the same problem.

Long story short: the camera is using a fast exposure time to keep the subject from being "blown out", i.e. overexposed, when the flash is used. That means that the foreground is going to be sharper but anything in the background will be lost in darkness if the ambient lighting is low. When you leave the flash off, the camera will use a longer exposure time (or shutter speed, if you will) to allow enough light, which also lets more of the background be seen in the picture.
Another thing to consider is that if your screen is set for auto brightness control, you will not have the same brightness when viewing the gallery pictures that you will when looking at the camera view. The camera view is full brightness at all times, but if you're viewing the pictures that you took in the gallery, screen brightness will drop down according to ambient lighting. Photos definitely look dark if you're looking at the gallery by lamp light.

That's interesting stuff, but doesn't really apply to the problem I described (at least the first part... the screen brightness setting stuff is potentially related, but isn't in my case). The exposure time is fine, it's just **when** the exposure starts that is the problem... a little too late, IMO. Really wish there was a way to adjust when it takes the photo in relation to when the flash is fired.
The foreground objects aren't lit up at all. No difference between foreground and background. Sometimes, I'm taking a picture of a t-shirt laying on a flat surface from 2 feet away. Without a flash it looks pretty good, but it's a little dark so I decide to try the flash to see if it'll lighten it up a bit. Instead, it makes it look like I turned out half the lights in the room.... way darker than no flash.

Same here, three friends of mine too.

I'm having the same problem s5 neo

I just figured out how to correct the pics from coming out dark. Go into camera-settings-exposure value-slide to the right to 2.5 or more.My pics come out fine now. Indoor light normal daylight.( with flash off.) I will know more in other settings (places ,situations )if it needs to be tweaked again.

no problems here
my settings are AUTO MODE
flash AUTO
no effets at all
and still i get good shots in night

Power/current draw issue?
Mine was doing this, and I noticed the first flash (ranging) was fine, but the second flash (to illuminate the image when taken) was much weaker. Whilst plugged into charge, repeated low light experiment, and the low light flash illuminated image was fine!! Maybe battery on its way out?

Screen turns on slowly

Whenever I unlock my device the screen turns on noticeably slow, it's like it's trying to transition but it isn't smooth so it feels off.
What is strange is that this doesn't happen when my phone is tilted at a <45° angle, it just powers on almost instantly with no slow transition. Anyone have a similar issue or know of how to fix this?
Edit: I take the angle back, it seems to be ambient lighting based. Still not sure how to disable this "feature"

Mine is extremely fast

Yeah it is affected by ambient light sensor... just tested it myself now... but sayin so.. might also be affected by the low battery,

I'm guessing it's purpose is so it doesn't turn on too bright in dark or dimly lit rooms and allows your eyes to adjust. Which is a nice feature now that I think about it, I've been blinded by previous phones numerous times when I turned them on at night. I don't know though, it just lacks a certain smoothness that the device's other animations have.

What bothering me the most is that we can't adjust the brightness on the always on display... is too bright

In display settings you have an option called "keep screen turned off", which prevents the screen turning on accidently in dark places such as a pocket or bag.
