[Q] Camera keeps focusing? - Nexus 4 Q&A, Help & Troubleshooting

The camera focusses over and over again, is that the way it should be? It auto focuses very often when I try to take a picture.

I have the exact thing happening with me. I think it may be the camera in this phone. My RMA did it also (before I sent it back, because it had more issues than the original). Doesn't focus this often on my old Samsung Infuse running 4.2.1.

Mine does it too, not sure why. I've found that once you hold the button to focus, then slide your finger off, it stops focusing. Then tapping the button should take the picture. While it's a crap method, it works for me instead of trying to time the focus correctly. Alternatively, simply tapping the button should focus it once and take the picture, though it may not be great in some cases.

So it seems to be normal I guess!

It's a feature, though not working very well. The idea is to have it constantly focused so you have zero shutter lag when you press the shutter key.

HD2 Camera Lag

Hi all, I was wondering if anyone could help me with a problem. It's nothing that's going to kill me but it is a little irritating. When I hit the shutter button, the camera doesn't immediately take the picture, there will probably be about .5 to 1 second of lag in between pressing and actually getting the picture. If this is normal then fine tell me. If there is a fix I would appreciate a link to a fix or an explanation on the fix. Thanks.
AFAIK that lag is the auto focus kicking in every time the image changes in the live preview....i wish there was a way to keep focus at infinity and leave it there permanently.
There is a way to turn off that delay...I just can't remember what it is
Whatever it is, I've done it, because I don't have any delay between when I touch the shutter and when the image is captured. I could have sworn it was a setting in HD2Tweak or BsB Tweak, but I can't for the life of me find it now apparently. I'll let you know if I recall, but it's out there, I promise
Thanks I'll keep waiting. I have BSB Tweaks and there's nothing about camera delay, and it can't be the auto focus because I allow the camera to autofocus THEN I take the picture and that delay shows up.
I guess coming from other auto-focus smartphones, G1, TP2, Blackberry, etc the autofocus lag on the HD2 is so incredibly fast compared to all others I've never even noticed it.

I Agree......
so there's still no fix... ahhhhhhhhh oh well -.-
i haven't done any tweeks and there is no delay unless I'm using the flash...
there are 2 ways to take a picture
press and hold
this will focus then capture
tap quickly
fast capture

Jimmy, you're a cotton picken' genius.
So yeah I tried it and that's obviously the difference. For anyone who's curious, I just took the same picture 10 times, 5 with the fast capture, and 5 with the focus then capture, and honestly neither way was consistently better at getting a well-focused picture Try them both, see which works better for you, but I don't think it really matters which way you choose

[Q] Camera focus problem

So, just curious if anyone knows if there's away to fix this or not. But I'm have problems with the camera and it focusing on close up objects. The only reason I bring this up is because when the camera app "tries" to focus, the subject in question will come into focus, clear as a bell, and then go right back out of focus and it'll take the picture. And yes, I've got spot focus on, and tap and hold the screen where the subject is. still nothing.
i'm hoping this isn't one of those hardware to software hindsight's where there's no way to force the camera to focus where you want it.

Not sure tap and hold screen part. You have your finger on the screen when taking the pic? Maybe I just misunderstood you. But you normally tape the screen where you want to focus and then it should focus automatically and then just snap your picture.

Nah, you do have to tap and hold in order for it to take the photo, thats normal. My camera focuses though and takes the picture no problem.
yeah, you can either click the little shutter button or tap and hold a spot on the screen and it'll focus there and snap the picture.
guess i should have been more clear. its having a problem doing macro focusing. if the subject is a food foot or more away, it focus every time, perfectly.
the problem is when i'm trying to take a photo of something very close to the camera. And the only reason I'm asking about this is because when it "tries" to focus, the image will indeed come into perfect clarity, and then go right back out. and sometimes several times as if the focusing is trying to find the right spot. and ultimately it just gives up and everything is blurry. And I'm left going what the...? because obviously it can focus on it, but why wont it?
My temporarily solution for now is to zoom in that tiny bit allowed and use that to get as close to the subject as i can before the auto focus stops working and get the picture that way. still not really what i want, but it'll work.
Set the camera to AUTOFOCUS, open the keyboard and use the ENTER key as the camera button.
Additional tips.
Turn OFF shutter sound and timestamp to speed up the photo taking process.
Leave ISO and Whitebalance to auto as they seem to work pretty well on the shift.
Quality HIGH
Geotag off (unless you REALLY need this)
NO review speeds up time to next shot.
Center area metering mode seems to work surprisingly well on the shift, especially with flash set to auto.
Also, note, the CLOSER you are to an object you are photographing, the more still you NEED to be. Panaramic/outside shots with a large DOF are awesome. Closeups at 6", you seriously gotta lay off the coffee and brace yourself well. 1mm of hand movement will blur your photos really bad. That's a intake of breath or exhale!
This isn't exactly a professional high speed Nikon with prime lens we're working with. Set your expectations accordingly.

Ok, I take back what I said about it working for me because I have the same exact problem with it looking focused and then going out if focus.

I'm seeing the same problem. It focuses very clearly just before snapping the shot, but then the picture it takes is out of focus. I've tried the tips here and nothing improved on the problem.
Cameras need light to focus. It's going in and out of focus because it doesn't have enough light to tell where the object is in relation to the background. Plus you can only macro so close with a camera lens. Try getting more light in your shots and see if it helps focus. I ran into this yesterday and fixed it by moving the object to a better-lit location.

I know this thread is old, but I think this is a big problem. Even if the subject is well lit, and you use spot metering or tap on an object just a few feet away to focus, the lens will focus and you will see the object become really detailed, then the focus decides to focus on something behind it, rendering the object blurry. This is the case with almost every photo that I take of any object within 3 feet.
Lets say I take a photo of a flower outside in the daylight. Any foliage behind the flower will be focused on, even if you press directly on the middle of the flower.
My theory is that it seems to focus better in lower light situations, where your subject is the only thing lit. If the entire frame of view is well lit, it will make the majority of the image sharp.

[Q] Camera Locking Up An Issue?

So I was using my phone yesterday to take pictures of my computer. I tried on two occasions to touch and zoom in on an area (which worked fine) but as soon as I press the shutter button to take the picture, the phone would make a weird noise (seems to be coming from the lens?) then it just freezes. It eventually took the picture after the reset.
I have to hold my power button to get it to fully reset. Then this morning I noticed that my clock and date were all messed up.. set back to 1970 and time was reset.
Anyone else experienced this before? Nothing else is wrong with the phone but I'm not sure if this would be a software or hardware issue.
Thanks.
Yeah Ive had the camera app lock up a few times. Shutter button does nothing (didnt notice any sounds as I was outdoors), closing the camera app does not fix it, full restart is necesary but my clock worked fine at boot. Ive also had an issue where if you touch to focus and then swipe to see the gallery then the LED flash will stay lit indefinetly, forcing you to go back to the camera app and re-focus.
What rom / kernel are you guys using ?
Not sure if this is related but I've had the camera refuse to take pictures a lot, especially in low light - the camera cannot seem to focus so hitting the shutter button does nothing. I find switching to another mode (video for example) and then back again sometimes cures it. I've also had it lock up and leave the flash on. I'm surprised this got through testing as it seems quite a common issue from other N4 users I've spoken to.

Same issue here too - just received mine 2 days ago and I sometimes need to change the camera to video mode then back to picture mode for it to be able to take pictures again.
Pure vanilla phone here, no custom kernels or any roms of any kind.. hell my phone isn't even rooted.. lol.
I've just started to notice that since I've been trying to take more pics with my phone lately.
And yes I've been seeing issues with the camera not wanting to take shots or focus properly either.
Same issues yesterday i was taking pics of my x-mas tree and gifts, suddenly the camera wouldn't focus anymore, had to restart the camera app, also auto focus is really not functioning too well... It can't seem to lock when focused on a subject...

Huawei Nexus 6P Camera App issue

I've recently purchased a Huwaei Nexus 6P. It's fantastic in every way including the camera... That is of course, when I can get the app to work. I use the camera to take pictures and occasionally video about 5% of the time. The app just hangs on the screen just before the viewfinder appears, and the only way to get the camera working again is to reboot the phone! It's incredibly frustrating, because everything about this phone is flawless! Anyone got any ideas?
you might have to take advantage of the warranty to get a replacement, if it persists, when i open the camera app on my Nexus 6P, i do not get that issue. however, i have only owned mine for less than 1 day. so we shall see....
BTW, i'm curious, does it still do that even if you double tap the power button when screen is off?
I've noticed that it only really does it when I come back from videoing something. It doesn't do it with the double tap the power button also, I don't think it's the handset, just the app I think
Mine acts a little wonky at times too. I tried to reproduce the issue you said you're having and can't get mine to do that, however mine does a few other weird things.
The camera on my phone takes a lot of double photos. I'll snap a pic and look through the photos quick and i'll see 2 of the same pic, but the google photos app only shows 1. If I delete that pic then both disappear from the camera app. I also get some pics that turn out as just a grey screen like the photo doesn't process completely. I've also had a few pics randomly disappear after closing the camera app. I'm really hoping it's just a buggy camera app.
I get the same issue as the op. But mine eventually says "cannot connect to camera" after 10 seconds or so.. Have factory reset a couple of times too..
Also my NFC of pictures from oneplus one doesn't work, 6p goes blank screen whenever I try to send...
Is there a way to take a picture while shooting video? If not, is there an app that you can recommend?
Unfortunately the camera situation is a bit beta-ish

What is wrong with S8 front camera autofocus

Hello. I am new owner of S8. As they claim front camera now has autofocus so selfies will be now "sharper" .
I dont know if I just have wrong model but when I am doing selfies really close to front camera they are really sharp.
However if I move camera little bit further it start re-focusing almost all the time. If I touch on the object sometimes it helps a little bit but it still not good.
The best result I could achive, you can see on the photo (and I tried many times and others were even worse). The text is totally unreadble. It is same with faces, but you can see it better on text.
I compared it to much cheaper phone Honor 8, which does much sharper photo without any autofocus.
Does any of you have the problem, or it is just me?
I tried restore camera setting but it didnt help.
Thanks for feedback. (cause I have no feedback from samsung )
I got the s8 plus and for me the front camera is beast! I know back on the s7 the camera was eh and the keyboard lag was real so I got the edge. It could be the camera or you could be snapping the camera too fast. Takes a sec to grab the image.
Do you have selective focus on? This mode will blur background to simulate portrait mode with telephoto lens on DSLR. I find it useless, but stupid iphone has it so why not galaxy?
Mine is not 100% sharp either (however much better than yours), but I have low light now and get shutter speed of 1/24sec, it's hard to hand held photo at 1/24sec without some shake. Need to retest this in full sun tomorrow.

Hi, no I dont. And this is another problem. When I try to do picture in this mode it always say me something like "Picture was taken but the effect of contrast cannot be used because no object was reckognized" . So there must be something defenetly wrong.
And when I was doing photo I was waiting more than 5 secs to focus but the result was still same. And I put phone on the table so I didnt move with it at all.

Thats sounds similar to message I got when using selective focus. It tells you that it couldn't recognize your face so the effect wasn't fully applied (in selective focus that effect is to keep sharp focus on face and blur everything else). Seems like you have some effect enabled and that could be your problem. I never got any msg, except for selective focus, but didn't have much time to play a lot.

I tried factory reset as a last option and it still didnt helped. I reviewed lot of videos and pictures of S8 online and for sure mine is behaving different. Probably I will have to take my S8 to the nearest service..
Sounds like you do have a problem. I used my S8 and stood back and the picture was focused. Closer ones have always been focused.
I had the same issue, but really don't know If what I did was the fix, because this issue was happening every time I open the camera app after a while (like half an hour) and I had to knock my phone just to wake up my focusing sensor or what ever it called, but after I:
- re-enabled all the disabled bixby apps.
- stopped using my car magnet holder - so it never gets too cold because of the car's AC and never gets attached to a magnet.
after that, camera never miss-focusing anymore, now more than 3 hours.
So please, if anyone had this issue and:
- not using any magnet holder.
- not disabling bixby apps.
- not having the phone too cold.
please tell us to be aware.
I know it's not logic, as long as I can use the camera normally after I knock the phone, so it might be a hardware problem, but I'm sharing my experience with you just to find out the fix.
Thanks
Update: Nothing from the above was the issue, still; miss focusing, even after a factory reset... waiting for July update and see if they will fix it.
Hey there, I too have an issue in front camera of my galaxy s8 when I put it too far then it shows blurry image but when the camera is nearby the object then it shows some good quality, but not showing as much good as it was showing before .
i have the same issue. But the camera works when it wants to work... but sometimes is blury (most of times)
