Screenshot quality - Huawei P30 Pro Questions & Answers

Has anyone noticed that screenshot of some image (for example in gallery), has poorer quality than the gallery picture itself, when you compare them afterwards?

You can compare resolution of those screenshots, because they could be made when screen resolution was set differently (HD+ of FHD+)

Improving the stock "gallery" app

Is there any way to improve the gallery app by allowing the zooming of images upto 100% of their resolution? Even photos taken with the camera, if you zoom in, the quality looks crap because of the downscaled image.
I heard somewhere that this bug is fixed in Froyo - but can't remember where exactly

[Q] Camera Problem

Recently i purchased Galaxy Note & i really love it but i dont like its camera.
When i open my camera app picture look beautiful & very clear but when i shot the picture it becomes dull. I tried several other camera apps also same result.
I think its because of HD display picture looks beautiful before capturing it. After capture the picture it becomes dull. I am confused why so? its because of HD display or software problem or hardware problem??
Anyone facing this problem or am i alone??
Cam FW Version: OOEI08
Phone FW Version: OOEI08
Please reply me friends. if its hardware fault then i have to return it
i have problems in zooming...autofocus works very bad..
Without zooming i have good pics,expecially macro
Cam FW Version: OOEI08
I think in software problems,not hardware
Waiting for next Firm upgrade...and android 4...
You are not alone. I was about to post a thread with the exact same problem. I'm really disappointed at the moment as I'm uncovering more and more problems with the phone each day.
Software issue
I was having the same problem, go to settings, ISO, remove from auto to 800, the pics wouldn't become dull anymore... i hope...

All cameras with digital zoom will look very bad if zoomed in. It is because the image is enlarged using its pixels rather than the lens....so as you zoom in the pixels just get bigger. I t's just like when zooming in on a photo using pinch to zoom.. ..if you zoom right in you can see individual pixels and the image will look blurred.
This is not a fault, just one of the downsides of using digital zoom.

It's not digital zoom, it's definitely the auto focus.
I have a batch of good pics from when I first started using the Note, so makes me believe the latest firmware update messed things up, especially since macro pics look fantastic.

Forgot to mention, I am experiencing the same problem as the original post. The pictures look perfect in the frame a micro-second before capturing, then the actual image turns out a bit fuzzy.

I had the same problem, but I think I have solved the problem now. When I took picture, it turned out to be very dull. I was playing around with my case today and all of a sudden, I found a clear film attached to the lens. After removed, the new picture taken became well again. You may want to see if you also has the film on the lens not removed.
I wish it was that simple.
Something in the image processing is softening the image before it's saved to the phone. If anyone has any suggestions please reply (though I've pretty much used up all the combinations).
Note, (ha!) the front facing camera takes nice crisp images, what I would also expect from the main camera.
Yes im facing same problem! I see a nice preview and when i take a pic it looks really bad ! It is disappointing really...It was not like that on the Galaxy SII.
A few things to try.Enable the anti shake function and try to keep the phone still when taking pictures.No phones take good pictures in low light situations,so when abundant light is not available switch to night mode.This will brighten the picture considerably.
Also I find the auto ISO tends towards the low setting even when light is poor so adjust the ISO manually.This might explain why some people find pictures a bit dark.
The image for me after taking an image is very dull. Like the recorded colours are reduced from what you see on the screen before capture. This is also true for video recording. I have attached a photo compairing the images of captured vs shown on the screen before capture. Hopefully someone can fix this. It must be a software issue because the hardward already shows great images before capture.

Which firmware version are you running?
hi. actually i got this problem on first time. i got this problem fix after i reset camera setting. try it yourself
I suggest you turn off the auto brightness and set the display brightness to Max and turm auto adjust screen power then try again.
I think you think the pictures are dull after they were taken because of the screen auto brightness .
I figure the camera app will increase your screen brightness for whatever brightness setting you are on and the gallery app. Wouldn't.
So you will see a duller image in gallery preview versus the camera app viewfinder , hence lead you a misconception of the picture look dull compare to the camera viewfinder.

It actually has nothing to do with the screen, rather it's how the image is captured. The software is softening the image, so even downloaded images appear dull.
And it's only the rear camera. My front camera images are crisp both on the Note's screen and when uploaded elsewhere.

Your right, brightness was set at 0% but camera app always goes to full.
Silly me!
However, the problem is still there but not so obvious as in the images I posted. The colour is undersaturated compaired to viewfinder and its also blurred/ not as sharp. That is also when taking a photo using a perfectly still stand.
I'm noticing the same thing. The pictures are dull and not as sharp as what I see on the screen. this is a huge disappointment that I hope Samsung will fix soon.
i would like to know some fix about this too... hopefully there is a nice reasoning to image becoming dull...
faced kinda a similar prob on my HTC desire hd wherein the pics became yellow however changing the AUTO WHITE balance helped me.... However on my note it doesnt.

General [CLOSED]GCam 16MP, 64MP and Raw compared

I downloaded the Wichaya_V1.4 GCam on my Zenphone 8 and found that it can record 64MP jpegs as well as the normal 16MP and Raw file options.
I did a quick test to compare the quality and usability of each version: I took a simple shot that included highlight, shadow, fine detail and strong/subtle colours. The attached screen-grabs are from a small central area of the picture.
The storage size of the shots are 1.8MB. 6.2MB and 13.7MB respectively, so the Raw file is over 7x the size of the smaller jpeg. All details are shown at the same size so the quality and sharpness can be compared.
I found that the 64MP jpeg was both softer and grainier than the normal 16MP file. I sharpened it a little but I don’t think it offers any advantage over the smaller file because of the graininess. If you want a more retro film grain look this could be an advantage.
Straight from the camera the Raw/Dng file is very flat and requires post processing to get it into shape. It’s a 16MP file that contains far more information than the jpeg that’s recorded with it. I opened it in a Capture One (Lightroom or Affinity Photo, etc could be used) and spent time adjusting parameters to get what I considered to be the best version of the shot. There may be smartphone apps that could be used, but I prefer to do this on my laptop.
The outcome is that I will continue to shoot most pictures as normal 16MP jpegs but whenever there is something very special that I wish to capture I’ll switch to Raw + Jpeg mode. This gives me the regular Jpeg for reference and a Raw file to process later when I want to create the best quality of picture from the GCam.
Thank you for your review. Can you add 64MP RAW and process it? It should give some extra details.

A 64MP Raw option would be interesting and theoretically lead to higher quality results after post processing. Best to make a request to the developer, Wichaya.
I'm interested in getting the Zenfone 8. Does OpenCamera shoot in 64mp? I'd love to see some examples!

I don't know if Open camera can record 64MP images as this is not mentioned on its website, but it's free to download and worth trying out. In a previous post I compared the GCam, Asus camera and Open camera night shots. The Open camera gave poor results so I personally would not use it as the quality of low light shots is important to me.

Switch to 64MP mode in the GCam interface, not in the Wichaya settings. See Screenshot,

Question Samsung camera mod

I found that using screen recording while using samsung camera app in photo mode makes the field of view wider compared to video. And dynamic range is better also.(forget 4k). But good for social media sharing.. but the only problem is the zoom toggle in the way. Is there any way to remove that toggles.. maybe a modded apk or something???...
I think it's because when the camera is in photo mode, the app uses the whole sensor. This means that it is recording with a resolution of 3000x4000 pixels (3:4 aspect ratio). But when you record 4K, the camera app uses only a portion of the sensor equal to 2160x3840 pixels (16:9 ratio). That is the reason you see a wider view in the photo mode and not in the video mode. The only solution right now, might be to use OpenCamera to record video but you have to select the 3:4 ratio in the video settings. If you do that though, OpenCamera will only film with a resolution of 1440x1080 so the video will not be that sharp. I admit, I would love to see a mod or a toggle from Samsung that lets you record in 3:4 though.
Thanks. But what about the hdr.. i mean i have tested it and the hdr performance with ultrawide camera in screen recording is great compared to normal video capture. Even in low light the screen recording looks way too wider and brighter and had great dynamic range. (I have also tested shoooting in 1:1 in video). Kindly test it out and see it yourself. But don't pixel peep it's obviously less crisp than 4k. But great for social media.
I see what you mean. Video from screen recorder is a bit different from video mode. However I do not know why this happens. I suspect that maybe screen recorder is not able to capture the whole color gamut of the HDR preview.

Question Stock camera low resolution pictures

Hi all, I noticed that jpeg pictures taken with stock camera, even at 108mega pixels are not so large, the are around 4mb. I also have gcam installed and the ones taken with it are 44mb.
No way to increase stock camera quality?
Using stock camera the image file size is approx 36 Mb when selecting 108Mb camera on my S21U (SM-S998B).
Selecting HEIF format reduces it to 30Mb.
Yes, mine to. But if selecting 12mp the image become 4 mb

You can enable 108mpx in aspect ratio select, you will get 30MB Picture as you expect

Dear jacopastorius, JPEG is a low-resolution image format. If you want a high-quality image, you should try png, which is used for high-resolution images.
