Zenfone 5Z 8/256GB - Camera in low light problem - Asus Zenfone 5Z Questions & Answers

Hello.
I have a frustrating problem with my asus zenfone 5z 8/256gb version.
Camera performs well in good light condition, but when it comes to take photo in low light for example in home with bulb light or when sun comes down i got problem.
Cuz camera preview looks like have 5-10fps? And talking a photo takes a while I mean click on button and i have to wait couple of sec without any movement otherwise i will get so blured photo..
Also I have a second problem in low light i getting strange white/color lines, something like flickering...
I make post on official asus zentalk, but they said "Under normal light source brightness, the camera preview frame rate speed is 30fps; in low light environment, it will be reduced to 8fps, increasing the exposure time and increasing the brightness of the preview, so the preview may result in afterimage, which is the design behavior." - And its funny for me, because for example Pocofone F1 with same sony sensor don't have that problem.
Now i don't know, is that issue with asus software or it's issue with camera hardware and I have to go with phone to service?
Well if it's software issue, any of custom rom fix that?
There is few photos/videos:

What's wrong with this phone.. ?
Thank you for any help!

I have the same issue both with the low quality laggy viewfinder in camera apps (like Snapchat) and the flickering screen / vertical lines in low light. Focusing is also not as reliable in low light.
My main camera's focusing is defective and doesn't work anymore. I am attempting to get it replaced under warranty (I hope they ignore the unlocked bootloader, if not then there are replacement camera modules on eBay).
I don't think a camera replacement would help the laggy viewfinder in camera apps, but I will report back if the flickering/lines is improved in any way.

Same to my phone 5z. Video quality not good 8n low light condition. The slow motion video in low light also terrible

Just got my phone back from Asus with a replacement rear camera.
So far, the vertical lines and flickering have not improved. Focusing and taking videos (in the Camera app and in social media apps) still have a lot of flickering and lines.
Although, I did notice that Snapchat has much improved video recording. Not sure if it was the camera replacement, or the update to Android 10, but the viewfinder in Snapchat has minimal lag and takes much better videos than before.
Edit:
I can confirm MUCH better camera quality/smoothness in 3rd party apps (specifically Snapchat and Instagram) on the official Android 10 update. My snaps are very smooth and locked to 60fps, even in the dark (although the images/videos in general come out a little darker).
Some of the custom Android 10 based roms I tried (which are currently based on the Pie vendor) have significantly worse camera image/video in 3rd party apps.

Same problem here. That's very annoying because sometimes I'm recording in good light condition but background have some dark places then the lines are constant flickering in that part. This is ridiculous bad software problem.

Google Camera mod with HDR+

Anyone else give the modded camera a try. I just installed it & I didn't experience any issues. I'll test it some more tomorrow though

Im using Mod rom viper 10 5.1.1
Im realise that latest HTC camera for HDR+ seems like have compress picture to reduce noise in the picture same like google camera apps,
I also try modded google camera apps and the result was almost the same (noise reducing)
which version u installed guys?U have weird noise pattern in low light?
Yeah, super noisy for me too, stock cam takes way better pics.
Are you all on stock or AOSP
I've tried this on both stock and PureFusion, there's always a noise pattern but it's most noticeable in low light pics. The noise starts about 1/4 of the screen away from the home button and continues to the edge of the picture facing the selfie cam. It's only our phone that has this issue so it'll likely never be corrected.
This is somewhat disappointing, as I was hoping this would help camera quality on AOSP roms. I loved LOS, but I couldn't take a good picture to save my life. The stock sense ROM camera really makes use of that camera sensor, as it should. Still kind of bugs me the Google Camera doesn't make better use of the sensor, since it uses the same camera sensor as the 5X/6P (10 has OIS, where the 5x/6p does not), and those phones take great pictures. I know there's more to it than just "your phone has *x* sensor, so we can take some great pics". It's just a little annoying, is all.

Blurry pictures of moving objects

I bought the G3 about a year ago for its praised photo quality. Since then I experimented with different ROMs, from Stock to Limitless and now Fulmics. With all ROMs, many of my pictures are blurry. It happens almost always with moving objects (even of very slow speeds), but occasionally with still objects too. I have noticed that turning on the HDR function makes a huge difference on capturing speed and image quality, but it heavily depends on the environment (meaning that I have to take a photo, turn HDR on or off and retake the photo). Is anybody else experiencing the same issues? Is my camera broken or is it a software issue?
HDR will need more time to take a picture so you need a still shot. Does that issue occur on stock rom as well?
I noticed the lag when HDR is on, but the pictures are blurry with HDR in on, off or auto setting. I did use the stock image quite some time ago. I believe that the overall quality was the same as Fulmics/Limitless, which should not be surprising, because they are both built from stock and use the same proprietary camera driver (is this correct?).
I remember that the image quality of AOSP was terrible, because it cannot take advantage of the device specific features such as the laser focus (please correct me if this is wrong).

Is there a way to fix dark video on modded gcams for Oreo roms?

Hello, i've been using arnova's modded gcams for a while, and noticed that video recording is extremelly dark, and sometimes get black screen flashes on it, not even close to photo's quality.
The only camera that seems to be doing an extremelly good job with videos is the oneplus modded one, but it lacks a lot of features.
Actually the image quality of the modded Gcam is shocking when enabling hwhdr on debugging and setting hdr to high, video doesn't stand a chance. As it doesn't happen only on one app, I believe it is a system or a camera2api configuration that the oneplus camera and the default camera ignores (I am running Pixel Experience, feb latest build, but it's a thing on every Oreo's ROM).
Is there anyone that knows about the topic any way or idea to debug it -be it from the camera source files or from the c2a settings-? It would be insane to have also the video ia for stabilization of the Gcam and maybe it can compare or be better than the OnePlus Camera.
Open to suggestions !
They is another problem with the modded gcam, when we select 60fps option camcorder the screen flickers while focusing and thats been recorded
There's nothing to do to check flickering, dark video and fix colours on preview? images looking a bit color-dead before obturation on some cameras, seems that only aplications that overrides those settings are working good. (modded gcams are dark and flickers on video, apps like instagram that doesnt obture gets a bit of lack of colours since preview doesnt do a bit of hwhdr to have an more accurate end result to obturation and also nicer looks on instagram photos). Seems to be a problem with the phone configuration since the camera can record well on other devices, and the op camera can record well on ours. Not like there are no ways around now, we can use both cameras and take the images with stock camera before uploading them but in long term it would be a nice improvement on social networks direct uploading, easier to take videos and photos on a single application (also to have gcam benefits as it is video stabilization). Sorry if I didn't explain myself properly, im not so good at english. Also, I didnt develop directly for android/camera but if someone with a bit of idea gives me the hand I can check out the settings. I don't have so much free time to learn now but as a developer with a couple of tips on the topic maybe I can find a way around to check those settings. Or if an experienced developer with time and will to do it I can help out maybe. I believe it's worth to give it a look

Big camera color and HDR improvements

In the latest update sony seemed to add some camera updates besides that audio setting.
(50.1.A.13.83)
It seems there is more color after you take the picture.
Also when HDR is on (manual mode), it seems it only does a hdr photo whenever it's needed, for example when im just taking a photo of an object it takes a single photo and does no hdr but whenever the background is brighter than the foreground it takes 3 photos and then combines them.
Anyone else noticed it?
Yes ! I was about to ask, if it's just me or the camera takes much better low light photos now ?
Before it was just bumping ISO to 12800 in real low light conditions, and the photo quality was like well, 1/ISO
Now not even the used ISO level is lower, or at least not bumped so quickly, but even the Superior Auto mode used for low light produces more detailed photos. And plain "Night mode" photos are really nice now.
Now I really enjoy my Xperia's camera (which I really hated before, tbh...)
Really, really good job, SONY !!

Best Camera App for A2 Lite - Camera2 API required

Google Camera (all versions) running Pie OS has been very hit and miss in the focus problem, and therefore until a developer or OTA update can fix this issue, it is not recommended for pictures that matter. It is inconsistent as to when these issues occur. This being the case, if you are plagued with the Pie update, your camera performance results will not always be good.
After extensive testing with many hundreds of comparative photos taken with many camera apps this is the simple final conclusion:
Note that all these (except the stock app) require Camera2 API. Instructions elsewhere on this site.
For outdoor photos in bright light: Winner Stock A2 Lite camera app with the following settings:
Picture Quality:High, Contrast:Low, Saturation:High, Sharpness:High. These settings tend to take faster photos than HDR with similar results.
Note that all the camera apps work about the same in overall picture quality and only minor emphasis on color variations. While the google Cameras had a better saturation and warmer tone, the HDR artifacts in the sky make the photos only usable at lower screen resolutions. That limits your ability to crop or enlarge to bigger sizes. The stock camera did not exhibit these with HDR on.
For Indoor and low light: Winner in every test was the Pixel 2 camera app (GoogleCamera-Pixel2Mod-Arnova8G2-V8.2.apk) with HDR off or on depending on light levels. It produced sharp photos with surprisingly good clarity. The stock app was normally muddy and gcam 6+ was too grainy. As a bonus, the portrait mode zooms in (like the gcam 6+, which makes people look less distorted) and there is a motion video option (not tested yet) and lens blur that works better than the 2 lens system of the stock app, but the photos become only 5mp. Like the GCam 6+, HDR for solid color areas (like sky) had the same pattern. Haven't played with all the developer settings yet.
For ultra low light: Winner is the Google Camera 6 (MGC_6.1.013_MiMAX2_V1b_A8.1+fix_Hexagon_failed+blFront.apk) using the night sight feature found under More > Night. The idiosyncrasies of spontaneous app closure when a second shot is desired is annoying, however the results from their algorithm of image stacking is very well done. It also works well to create the smooth water motion for water falls and cascades, but only in dim light.
The gcam 5 app (GCamera_Mod_v.5.1.23_R5Plus_fix_crash.apk), that interestingly the pixel 2 app is based on, did not win in any category.
So I now have 3 camera apps to choose from depending on the photo required. Download an icon app to distinguish the 3 easily. I would imagine these results would be similar on other phones as well.
A note on HDR. None of the phone camera apps do HDR the way it is intended. In normal photography, HDR lightens areas in shadows and darkens blown out bright areas for a more usable photo by combining under exposed, properly exposed and overexposed images that are stacked and aligned. In all the camera apps tested, it makes little difference to shadows and even made shadows darker in the gcam HDR modes. What it does when needed is take multiple underexposed images (each at a faster exposure or lower ISO) and combine to increase (not decrease) contrast for a more vivid (but often artificial) contrast look, while better saturating colors and less noise for hand held images in low light. To do a proper HDR, you need to bracket the exposure and combine in photo shop (PS). There are phone apps that allow exposure bracketing and create the HDR in PS if you really want to get that involved. HDR+ only uses HDR when needed and HDR+ Enhanced the HDR is always on. When no HDR icon is visible, HDR is the HDR+ on when needed (auto mode).
I am currently running pie, and random focus issues have been surfacing for all the gcams. I read a comment that may be an issue with pie vs oreo, although not certain. It seems like Android One users are Google Beta testers. Pies battery life is much worse and no way to see what apps are causing the drain. I suspect it will get fixed in an update. Not for this forum though, there are already many out there for this issue. Main camera is set to Nexus 6P and Front camera a Nexus 5. I read elsewhere that this was optimal, but did not test if the others made any difference. The Nexus phones DO NOT use the same camera (sensor & Lens) on either the Front or Back camera so I am uncertain how much difference the setting actually makes. Most of the other settings were left as installed, although I am still testing to see if any improve the quality. Please chime in if you find any improvements and I will test and update this post. There is always room for improvements.
I would really welcome a more stable google camera build without the focus, night sight and HDR pattern issues. If someone has a line to the developer of these modded apps, please let them know.
Hi, thanks for sharing this. Do you have any specific settings for any of these apps? (Besides HDR)
Which gcam do you use for front selfies? On r5plus mod i get dank front selfies in good lighting but struggles so much on low light so much grain, noise and distortion. Or do you have any specific settings? Thanks

I will do some more experimentation and update the post when I finish. It is very time consuming for the developer settings do not have easy explanations as to what they do.

Pixel 2 for selfies, but HDR must be off for the photo to record. BTW, the flash works, but not sure it is any better then ambient light. Main issue is the 5mp front camera is a bit outdated. Lipstick on a pig is still a pig.
thanks and keep up the good work!
i think test results need to be explained a bit more detailed. for ex. oreo or pie based? you know, it's reported a lot that pie has gcams' losing focus issues (mostly with flash, blurry photos)
and yes, HDR and saturation (or maybe more) settings sharing would be better...

Arnova's v8.2: GoogleCamera-Pixel2Mod-Arnova8G2-V8.2.apk (Arnova8G2, 2018-08-13, changelog)
Although I am not certain if it is the best. When visiting the rose parade floats, there were random times where focus was an issue. I will experiment further with other versions. Many of the apks that are not compatible will just not start up (black screen or return to home screen). It would be nice to find a more stable version.
I agree except for the stock camera For outdoor photos in bright light... textures are always "muddier" than gcam to me. It can have a more precise light sometimes but it's a price not worth to pay IMO. If someone doesn't want to be bothered I'd suggest to use only the google camera 6 in order to have at hand always the night mode, arnova is generally sharper but you need to fully zoom it to spot the difference... i noticed also that the night mode of camera 6 produces better results than arnova even in mid/low light scenes but not always and not for all the shots... smt i make two shots with arnova and camera 6 night mode and keep the best... pity that camera 6 doesn't allow to be started by double tapping on the power button though.
Are you running Pie or Oreo? Are you having intermittent focus issues with the gcams? Will night sight always allow a second night sight photo without restarting the camera app? Have you looked at a solid blue sky with HDR on any gcam, and is there a pattern there? Thank you.
BTW, all my tests I enlarged the photos to 100% pixel level and more in PS comparing many areas of the photo in unison.

I'm running Pie, i do have some refocusing (but often it stops) but only in very low light condition. I didn't experience problems on second shots of night mode but smt it quits when i select night mode though. I do remember sometimes to see a pattern but only in night mode and in bright light I think. That was also a reason for not to use always the night mode btw... will do a shot on a deep blu sky when I'll see it but as far as I remember I didn't see this issue with arnova at least
I use one Gcam app called "Gcamera" is only in english and hdr front camera works..but is a older version of gcam and don't have a night mode photo etc, IMHO the best choice is for video on 60fps the xiaomi camera (in Pie update 60fps is enable) , for general video and photo gcam (a lot of optimization and hdr+) , and for selfies gcam with hdr off..waiting for it to work.

I didn't test it toroughly but I had the impression the video to be more stabilized and better detailed with arnova than the stock one... moreover I can use H265 to encode it...
btw i do have focusing problems with gcam and pie...
At the moment, the only solution for focus Gcam problem, Is change 4:3 to 16:9 and restart the app...
? i'm always in 16:9 but when I switch it doesn't work anyway...

Try to force close the app, after changing the size
it's just terrible any news for update gcam app to handle pie?
This developer's works great for me, no crashes on night sight so far and more customisable
https://www.celsoazevedo.com/files/android/google-camera/dev-backrider/
Just don't switch to the front camera and photobooth or you have to force stop the camera to be able to save images
Try the bulkin043 V8Y

It is optimized for mi a2 but some said everything works except hdr on the front cam
