I want to know if a cooked ROM like the ones we can see here can enhance the camera quality by speeding up the shutter speed?
I have read that the 2.1 official update will surelly boost the camera too...
Yes it does...much faster making photo capture much more stable...you notice it more when taking pics in dark environment.
if yes how's your front camera exposure?? seems a bit high compared to old camera,selfies all seems so white now haha, however overall it improved a lot for back and front camera, good quality and nice shutter speed
Hi,
Take a look at the general thread about the update: http://forum.xda-developers.com/google-nexus-5/general/google-camera-update-t2720165.
Thread Closed....
Hi all, I 've been thinking of buying a new phone & I really like the g2 very much but the only thing that is stopping me is the camera performance.
Can someone please tell me after the Jishu/xdadebb mod how is the camera performance under low light, how is the autofocus in low light also is the continuous autofocus in the video problem resolved. How much is the shutter lag after the mod.
I really want to buy this device for the camera & its under my budget if the camera ain't good enough even after the mods I may go with oppo find 7a/oneplus one which are in the same budget but have better camera.
I dont capture my photos in low light. But the camera is pretty amazing with xdadebb mod, and Mi2Raw enables the G2 to capture raw footage as well.
The G2 and G3 has the same camera sensor, just that the G3 has a Z-Axis image stabiliser and laser autofocus. So if I were you, I'll go look at those camera comparisons on review sites comparing the G3, OnePlus One and the Oppo.
Edit: Video performance is pretty good too. xdadebb camera mod allows for tap to focus in video to focus your subject and it works well. It has object tracking too!
Edit 2: With dorimanx's kernel, I was able to turn down the mic gain when I was at a concert. That + the stereo recording = pretty awesome recording
Thanks @lowjinyik.
Anyone else using these mods please comment about the low light performace after the mod.
I haven't tried taking pictures in low-light conditions yet, I should, will do and compare later but under bright, sunshine outdoor, with Normal mode, I see virtually no difference in term of performance and image quality. There are several features that I haven't tried out yet.

The low light camera quality is good. The mod makes very little difference to low light pictures.
Thanks guys for your responses. I think I might go with oppo find7. It's better than the g2 in every aspect except battery life & OS updates. Which can be taken care by the VOOC charger & custom roms respectively.
We all know that most our photos get blury because of the shutter speed which is 1-2 seconds. Nobody found a way to reduce this speed to zero, but this phone's camera is still not very bad. So I would like to question all the i9500 users, what is the best camera app for this phone on KitKat? Or are there any mods or any other things that increase photo quality? I know how to play with the settings, so don't recommend me to do this. Stock settings are medium.
I am also using A Better Camera from the playsotre. But anyway, I am wondering if there are ways to increase our camera.
Thanks in advance!
Have you ever checked this folder /system/etc/camera? You can tune noise reduction, sharpness, contrast, hdr, night mode, light mode, nice food, scene recognition and many other algorithms as well. I have no knowledge and experience but if you want you can try and share your experience.

LOL! Why did nobody recognized before??
There was a mod that tuned camera long time ago, but in a different way - https://forum.xda-developers.com/honor-7/development/mod-camera-mod-100-jpeg-compression-t3340978
Anyway, Honor 7 camera is amazing and highly underrated - mostly because of too much noise reduction and too big jpeg compression. Just by changing camera app to a third party one (like Snap Camera for example) that allows you to change jpeg output quality to something about 90-95% makes REALLY BIG difference. Stock camera app simply compresses files too much and in effect reduces quality and amount of details. Files from stock camera are like 5-7mb each, while the ones from third party app are like 14-20mb! One problem though - sometimes, when image photographed scene has actually too much detail and resulting image exceedes 20mb you get nothing. Probably some memory issue.
Thing is, Honor 7 had great potential (and camera was just a part of it), but the interest in this device was killed by Honor itself. People who owned it mostly already sold it as there are big issues in current software that will most likely never be fixed. Therefore i would not expect to get much developement in camera area as the userbase is now reduced. It wasn't big year ago and it's only getting smaller and smaller.
Not much replies here. Anyone oriented on this matter yet?
First of all, I tried third-party camera app (Open Camera) that gives me 100% jpeg quality option, but I haven't tested real life quality out yet. Definitely bigger file size.
Video is the one I'm trying to focus on, tho. Open Camera gives me options for bitrate. Tried 50 and 40 Mbps. With higher dynamics real life framerate didn't go over 14 fps. With locked and somewhat under adjusted exposure, it can handle 30fps on 1080p. But it's no good when trying to shoot "professional" video. Didn't check the real life bitrate either.
As supevixen stated there's some threshold on bitrate and/or jpeg compression buffer. Any idea why?
So what I'm trying to solve is;
- Why there's so low threshold on buffer and can it be optimized? Could it buffer better if I used fast external SD instead of internal?
- How to optimize buffer to match hardware maximum?
- Should I continue using third-party apps or should I try to optimize stock camera .xml files?
- How to reduce denoising? (xml optimization)
- How to lock frame rate and/or shutter speed on video recording? (xml optimization)
I'm not very familiar with jquery or imx230 or much about the Honor 7 SoC either. I'm fast learner and very interested on optimizing the camera.
Ok, here we go. I'd figure that: "/system/etc/camera/multidenoise" -> "multidenoise.xml" is for the "selfie camera" as it states attributes for IMX134 and IMX135. So this doesn't need optimization, if I'm getting this right. "/system/etc/camera/davinci/imx230" has "hdr.xml", "imgproc.xml" and "multiframe.xml" files. "imgproc.xml" I believe has everything to do with the image processing. "multiframe.xml" has everything to do with denoising and luma enhancing, I recon. How to properly reduce denoising? Should I also tinker with luma enhancement or image processing? Also, as I stated I'd like to lock down the shutter speed on video recording, with frame rate set to 25. "/system/etc/camera/bshutter/imx230/" -> "algo.xml" has algorithms for shutter behavior. Any way to optimize those?
Or should I simply throw this peace of crap out of my life? Camera has great potential anyway, would be shame to toss it away.
If there's someone with some knowledge on the matter, I'd be more than grateful. Thanks in advance.
anamorphica, i didn't try modding original camera app by editing various files as i don't wan't to lose warranty, but i've tried many different camera apps and best one i've found is Snap Camera which paid version i'm using right now. Why? Simply because it can save jpeg files with 100% and it makes HUGE difference. Just imagine - files saved by stock camera are about 5-6MB each where files saved by Snap Camera are about 16-20MB each! And difference is really BIG when you zoom just a little bit and as we have 20mpix camera sensor it actually does make sense to "zoom" by just cropping full image to desired part and gues what - it is possible with good quality images. Of course you can save jpeg's with different quality in most third party apps (like Open Camera or Zoom FX for example), but Snap Camera seems to work best for me (it's interface is ok, it does have many useful options) and it also has amazing HDR mode (three images with different exposure are stacked together for final one - there are other apps that work that way but believe me - results from Snap Camera are by far best)
There is however one downside - sometimes, when detail quantity is to big and output image exceeds ~20MB files are not saved. It happens rarely (really) but it has to be somehow connected with amount of memory needed to that amount of data (in RAW data it has to be much more than just compressed 20 megabytes) and that's probably one of the reasons why stock camera app saves such highly compressed images. Take note, that every other "creative" mode in stock camera doesn't output full res images (light painting and night mode - they're about 8 or 10mpix as i remember) and i'm pretty sure that's also connected with memory limitations (probably not whole RAM - just the part available at the moment for camera sensor and GPU)
As for video quality, there's probably not much we can do, as our Kirin SOC is limited. Where Sony smartphones with same IMX230 can record up to 4k and have OIS, we can do only 1080p with just electronic image stabilisation and pretty low bitrate. Slow motion is also pretty bad with framedrops...
Anyway, as for me, Snap Camera is the best and i'm not going to mess with stock one. Just when i need those light painting modes or night mode - it's ok. But in good light i'll stick with Snap.
Thanks for your reply.
I'd like to know if buffer is really low/restricted due to hardware limitation. As I see it, Kirin is overkill for the needed buffer and RAM should be more than enough.
Someone made 100% jpeg quality mod to "media_profiles.xml", but every bitrate etc. values were set to very odd numbers. It's just hard time to believe that this phone couldn't handle more than what it does now.
btw. I read somewhere that Honor 7 GPU would be plenty for OIS as it should be implemented on IMX230 and people was waiting for firmware update to fix much of those restrictions, well we all know that update never came.
Our Kirin is not that good actually. Not only it does have issues with energy management (that's why apps in background are killed on stock roms and why battery times are much less impressive with CM roms - without agressive app killer built in stock firmware) but it is also crippled on GPU part (no Vulkan compatibility) and not really video capable - like i've said, phones based on different SOCs with same camera sensor are more capable (different codecs etc.) Our phone can't even record perfectly fluent slomo video with stock app - just try it, it's never without freezes.
All in all, i don't think it's worth mess with internal configuration files - you won't get too much probably, at least on video part.
