Why camera always out of focus after being in gallery or when p20 pro stand by? - Huawei P20 Pro Questions & Answers

Hello,
I have Android 8.1 and b137, Still waiting for Pie update and hope Huawei had already fix that issue.
Let's talk about that issue. I use a lot the manual mode then manual focus for streetphotography. The big advantage is you do not need to wait focus working to take picture.
When I set focus in pro mode manual and that I take picture, it's sharp. But... when i check and watch the picture i taken in gallery (to check if picture was ok) and that i go back to camera, i take a new picture, the camera is already out of focus.. It happen same thing when phone stand by (or I press off) and when message "tap screen to reactiate camera" appear... I must always repeat focus settings operations...
Seem p20 pro keep in memory all settings (Iso, speed, etc...) but not the focus unfortunatelly.
I even made a video:

Do you have this issue? Please try it and say if you have that issue also. Thank you!

Yes, same thing here. Pretty annoying.

Noticed something similar on Auto. Usually it focuses after a few moments, but sometimes I have to point it around or tap the screen.

Need help on camera focus problem

I had my X1 for about 4 months now....basically with a stock rom R1A (i'll update when R3A is out), stock panel manager and stock camera software.
Yesterday i was playing around with the camera and i ust found out that the auto focus doesn't always work all the time. Is this normal?
I assume the normal procedure is, I semi press the camera button, then the auto focus starts to work. The little white square shows up and the green circle also flashes rapidly on the top left corner. The picture will then start to focus and if it succeed it will show 3 green square. This is on auto focus anyway. When on touch focus it only shows one square.
The problem is now, sometimes the camera will refuse to auto focus. I semi press the camera button, the little green circle flashes but not as rapid as it is when it is focusing. The little white square is gone, and no matter how long i press it the picture just wont focussing.
Worth to note that this doesn't happen all the time....but it does annoys you when you are trying to take a picture and this happen.
Is this a hardware bug? software? something to do with light? or i just simply did something wrong? i haven't got a clue....
i would appreciate if anybody can help me....
P.S: does upgrading rom and using the new R3A camera software solve this problem?
me too.
press the button and sometimes it will focus on it's own and then at other times - day / night / moving / whatever - it doesn't.
i'm on stock R1A although added the MUCH IMPROVED R3A camera software... same old focus story though.

hmm....if i have to take a wild guess it could have something to do with the shutter...
but i dont know...can anyone else shed some light on this? any help would be appreciated
does it occur only when it is dark?
no,it could happen any time. not just at dark or any specific time...
drspain also point that out too...

I've completed my scientific testing and the results are as follows:
1. Auto-focus is random -at best- in performance. Again, doesn't matter whether it is day, light, night, dull, landscape, macro etc... it sometimes takes a shot, sometimes it doesn't. Sometimes, you press the button and walk away. 2 steps later 'CATCHHODDSSS' it takes a snap of your shoe or something sideways.
2. Best performance is with infiniti focus on using R3A software.
3. Definite difference between colour and saturation using landscape mode and auto mode or sports. Landscape seems to try and 'warm' images. TBH, auto is fine, even for most things.
4. The camera in the P1i is superior. I wonder why Sony didn't stipulate using the same tech... they are both 3.2 monkey pastels.
Cheers,
DrS
well, i've done my research too and i'd like to say that i've been unable to recreate the situation. It's focusing all the time now...no problem at all
weird...
and i havent done any upgrade and such.
Best thing we could say about this, is that this things occurs randomly
Well i can say one thing ....after switching to infinite ...its become better..doesnt take time to focus ..i.e capturing the moment we want or else it used to keep focusing and then the moment u want to capture is gone already...well i feel in infinite the focusing is also fair enough i think same as with focus...

HTc HD 7 Camera Issue

Hi
Got my Hd 7 from o2 pay as you go
Am quiet happy with it, but has anyone noticed that the camera is a bit rubbish or is it jjust me
Camera snaps close up are super brilliant. but the moment you try to snap far away subjects its all blurish
Its seems to have a digital zoom which just blows up to picture to distortion
I have noticed that even the zoom function just blurs it up as well
feed back would be appreciated
It's indeed not the best WP7 camera but it's not too rubish also. It should be no more than decent (while to video recording with continued focus is ace) . Can you provide a sample so we can judge ?
There was also a pink-camera isue with an earlier HTC device (can't remember the exact model) and problem was solved with a quick update.

camera on hd7 does suck... tend to bluish every single shot unless u play with scene mode .... thats one of the reason im trying something else .. maybe focus
Hmm.. do you think that it will be possible that they release an update for this?
Not too keen on getting it if the camera is useless.
I have the awesome pink hue issue with mine... and for the other guy... the other phone with the pink problem was the HD2.
anyone know if this is just the software or is the hardware?
ive noticed too that on long distance shots its horrible on keeping focus of the picture. Though i think that maybe because metering is set to center and it cant focus in that much in the distance.
Though your every day snaps are usually ok for me. No problems with tints or anything and i find the video quality to be decent
I haven't had any problems at all with taking photos on my HD7 - no focussing issues, near or far.
Are you guys half-pressing the camera button to focus first, before pressing it the rest of the way to take the photo?
This seems to be the biggest cause of issues, people not realizing it's a two-stage shoot process, just like with digital cameras.
Note to the OP: Metering is actually light metering and has nothing to do with focussing. If you have metering set to centre, the camera will adjust the exposure according to the brightness of the object in the centre of the shot. If metering were set to "average" it would work out the brightness of the whole frame and set the exposure to that. Nowt to do with focus.
Incidentally, don't forget to ensure the lens is free of dust, fingerprints and other crud as that will obviously make your pics look mushy.
nope i always press on the first stage and let it focus and then press

[Q] Sony Z3 Compact camera sucks! HELP!

Hey, i just bought the Z3 Compact The phone itself is very good, EXCEPT The camera! 20 mpx of what? The camera is so blurry and noisy. And you can see the pixels easy. This is so TERRIBLE i have to ask if there is anything wrong with it? I have had Android since it came out. This results are worse than what my HTC Magic did. A phone from 2008-09. I have tried different settings, no luck. Been like this from day one. So is there something wrong, or is this suppose to be the 20mpx camera? ...
Some examples, first pic is taken in daylight. You can see at the second is in darkness (Very noisy!) Front camera is even worse!!
Please get some help! I like the phone, but if the camera is suppose to be like this i'm switching it out immediately!
I'm new to Z3c too, my camera sucks in the first shots as well, but, so did my sister's, until suddenly, it got all well. I don't know how.
Well said about camera suddenly getting good.
My recommendation is don't use superior auto. Launch your camera from a shortcut and set it to manual and from that moment on it will always launch in manual mode, but not when you launch it with shutter key.
Once in manual mode, try my settings:
Exposure: one or two bars below value of 0
WB: auto
Resolution: 15,5 mpx
Focus mode: multiple autofocus (i think that's what it's called in english)
ISO: This is the most important setting. You can set it to 100 or even 50 to avoid noise and artifacts caused by heavy postprocessing by software. But, the lower the iso, darker the image will be. So on a sunny day it can be 50 od 100, On a cloudy day, a bit higher and in night photos 800.
Metering: multiple
Focusing: When you want to take photo, put object you want to take photo of in the middle and half press shutter button. When squares turn blue on places you want focused, keep shutter half pressed and you can then move your phone to left, right, up or down and not losing focus. That way you make your composition. When you think you have your scene set up, finally press the button all the way.
Once you set it up every time you launch camera by a shortcut it will launch in manual mode with settings remembered from last time you used camera so no need to fiddle with settings every time. Camera widget is very useful.
Avoid superior auto unless you're in complete darkness because in that case heavy postprocessing and very high iso that it always uses have to be made.
Superior auto uses very high iso values when not needed. High iso causes much noise on the photos, and sony software removes that noise and does it in a not so good way. That results in artifacts and 'flat' photos.
It sounds complicated, but it really isn't. I have SLR camera experience so it's natural to me. Once you practice half pressing, composition making and then taking photo people will wonder how can you make such photos. It's knowledge that you'll be able to use always in all cameras, phones and whatever.
I hope this helps and let me know if it does. I'm thinking about writing a camera tutorial with samples because not many people use the potential of it.

Thank you for a good answer. Some of the shots is amazing! Still, i can see them getting a little blurry. Also i think that if you can't choose auto and take decent photo when you are in a hurry it's actually a struggle. If you always have to set your ISO etc. Then i would rather bring my DSLR with me instead! Here are some examples from my previous phone. The S3. I set HDR on. Nothing more! Nice and easy.
I'm not saying this shots is amazing, but i just found it to be better overall than the Compact. This also have 12mpx less! Newer Samsungs have a pretty decent camera! So my questions is now, what other phone would you guys recommend? I was quite happy with my Samsung til it got slow and the battery drained out easily. I'm also happy with Sony, apart from the camera.
It's not unlocked.
Have you tried to use Google Camera? I think these crappy denoising algorithms won't be used in it. It lacks advanced options but if you just want to make nice photos with 'auto' i think it might be good enough.
Manual mode, much better photos than superior auto.

Well, it's true that auto mode is not good. I had an Xperia P before this one and never had any issues with the camera. It had 8 mpx of amazing quality camera on the daylight at least.
But as I said, once you set your manual mode, you almost never have to fiddle around with it. At least I don't. I set iso to 100 and when it's daylight i start camera by shortcut, and on night time i start it by shutter key.
Anyway, I keep my fingers crossed that lollipop will fix all that, because it's software issue only if you ask me.

Tried today with your settings. Works better, so thanks! Still very blurry, but not as bad like it was. Why haven't anyone mentioned something about the camera before? Since allot of you are experiencing it? Hope Sony will release an update soon because this isn't OK at all! The colors and details are pretty decent. It just becomes blurry and not sharp enough. and why can't we turn on HDR?
Everybody has mentioned it. It's the third most talked about thing with this phone after root and battery.
Apart from the low light algorithms the camera is pretty ****.
Like the others I hope L will fix it. Until then i just use camera fv5. It even uses the hardware button so it's cool. And much better pics
HDR only works in 8MPx mode. Can't turn in on in 15.5/20MPx mode. And it's not THAT great actually. Wise exposure helps more than the HDR.
Also, you could maybe try the Camera FV-5, which has a ton of settings and also RAW capturing abilities, if you'd like to postprocess the images on your own. But I doubt anyone is doing this and taking it somehow seriously.
You have to play around a lot with the camera, bringing down exposure as suggested is a great start. I left the size at 8MPx, and also played around with some scenes (useful in the night) or lowlight, you sacrify motion blur from long exposure time for more noise, but that's how it works in photography.
The camera is not bad, you just need to be patient with it, if you'd like to quickly snap perfect shots, this may not be the perfect device, however, if you use the camera wisely, it can deliver stunning photos for large prints.

The pictures you posted before from the S3 really aren't better then the Z3C. Why no mentioned anything about the camera before? I'd relay the question back at you, why haven't you looked up the forum, because there are really PLENTY of topics regarding the camera. So the only thing I can conclude is that you didn't even check the forum. Even the blurry pictures have been mentioned before. Like someone above mentioned, try Camera FV-5 or any other ap. I use Camera FV-5 myself and I'm really happy with it, even with an unlocked BL. Check out the topic I created (in my signature) and you'll find plenty of pictures from the phone. It can really make some great pictures, but as you said before when you don't have a lot of time to make a picture, to change settings it can really be a bich to work with.

Ok, i actually just want something nice and easy. When i take pictures with my phone i don't want to try a bunch of settings for the camera to take a decent shot. and doing this in sunlight for example when you can't see the screen at all? Instead of just pressing the camera button..Actually the superior Auto is so bad i can't even describe it. I got some OK settings now, but far from good. Of course if you play around with the settings any camera can be good, the thing that you have to do that tells me it's rubbish! Then what's the point? I could rather bring my DSLR. I would be able to take better pictures, without a hassle. For me a good camera is very important, that's one of the reason i brought it. And can you really defend a 20mpx camera from 2014 that can't even take a clear shot on a sunny day with perfect light in Auto mode?

I have actually seen your photos, i did go through allot of camera samples before i brought it. Little did i know that the camera was useless in auto mode. I know the shots with my Samsung isn't that good but still, this is shot in Auto mode. The first picture has HDR but nothing more. If you compare that to what i did with my Sony it's WAY better. Because as i said, if i want to take some amazing shots i will use my DSLR instead. And when i'm not having it on me i want a decent photo, but i just can't get that with the Compact.
And the S3 has 8mpx, the Compact got 20.
I changed the settings on my Compact, still blurry and un-sharp.

Sorry to say, but you've most obviously been too lazy to use the search function and you have even ignored the automatic search results while writing the title of this thread. Having said that, in the beginning you wrote about picture noise and that they come out blurred. Ok, but now you claim they're even unsharp. Sorry, that's definitely not a problem of the phone, at least you'd have the first sample with such an issue...
Regardless, please refrain from cluttering the forum by opening threads on topics that are already being *extensively* discussed. Thanks.

Definitely depends what you are photographing. At 20MP I've taken some impressive photos, for sure, but under closer scrutiny on a large monitor they don't look quite as good, and they fall apart almost instantly when post-processed. Sony's sharpening algorithms are far too aggressive so any high-contrast edges look almost posterized. Other aspects of jpeg processing also leave a lot to be desired, even at low ISO. In other words, Sony took a decent sensor and only lets us get mediocre results.
And, yes, auto mode is an absolute joke. I estimate about one in ten photos I've taken in auto are useable (many of them only after slapping on Instagram filters). I just wish I could start in manual using the shutter button. Still, I'm not expecting output from a camera phone to come anywhere close to a good compact camera let alone a DSLR, so in that sense I'm a little less miffed. But reliable auto mode is essential IMO since that's always gonna be the most used mode for quick Facebook/Twitter/Instagram update snaps, which is how 99% of people use camera phones. Epic fail from Sony on that count.
I am most annoyed at all the clueless tech reviewers who last fall declared this to be the best phone camera, on a par or better than the iPhone and S5. It's not. Not even close.

This. A million times this. How on earth did initial reviewers rave about the camera? My experience of its performance closely mirrors your own. Only a small percentage of all photos come out looking ok, even though I've messed around with wb, iso settings etc.
Same here, got my z3c yesterday and I am quite disappointed with camery quality. Images become really blurry, especially on a front facing camera. It is clear to me, that it's a software issue, because when I look at the screenm picture looks OK. But when the photo is shot, it becames blurry after pocessing. I used to have iPhone 5s before and it did amazing photos compared to sony's device.
And I also agree with an opinion that most people don't want to mess with camera settings on a mobile phone. We just want to quickly take a decent photo in an auto mode...

Time taken to focus scene

Hi
I have had the nokia 8 for sometime now. Awesome phone but like lot of people I am struggling with the camera app. Lot of people complain about the focus time in the camera app but no one seems to say the app never gets focus.
Now the problem I have is most of the time the camera doesn't seem to focus at all. I click the viewfinder hoping it will focus but it doesn't. When I put the camera in the monochrome camera the focus is ok but the colour one doesn't focus. I put my finger near the lens and find that the focus seems to be set right near the lens (finger is clear). I used a cloth and wiped the glass and then the focus works properly when I close the app and try again after sometime the same problem reoccurs. The same issue is there when I use the WhatsApp camera as well.
Now my question is this normal and same thing other people are going through and wait for an update or do I need to show the phone at the service centre.
What is the time to focus you guys are having on the phone.

Front camera delay between shots

Hi, when I'm using the stock camera software on my up-to-date, non-rooted A2, with the front facing camera, many times, it's impossible to click on the "taking a picture" button right after taking a picture, it's like frozen for half a minute or so.
It's very annoying since my gf is obsessive with taking different angles of the same photo, and it keeps us smiling like stupid for a long time without being able to take pictures...
Anyone else experiencing this issue?
Edit: I think that a viable workaround may be an app that can take high quality picture with the front camera, and is able to take a few pictures in a row (I downloaded some, but some of them shows me the picture after taking it, instead of going back to the camera screen, and some seems to lower the quality of the photos compare to the stock app).
Many thanks!
