Camera flash brightness with default camera app - OnePlus 5 Questions & Answers

Hi,
I was very disappointed with camera flash intensity one day while my colleagues were taking portraits in low light with their high intensity flash on xiaomi mobiles but my Oneplus Flash couldn't do anything.
I thought it was the hardware design and i thought to live with it.
But yesterday i installed magnifier app from playstore and observed that the flash was brighter compared to camera app.
My question is, is there a way to increase the intensity by increasing the amount of current pumped to the LED?

You may be able to do it with a custom kernel. Though they generally only offer options for the notification LED, not the flash.

UPDATE Comparison Pics with Galaxy S4 and 808pv added
I Really got frustrated by how they review cameras in web sites.
Although am not a photographer but atleast i know the basics and photography is my hobby.
First if all; What made me write (type!) This post because i noticed that many maanyyy dont know how to deal with this beast inside ?
So i have owned every well made camera phone till i settled with the one. I used the 808 pureview the N8 S3 and S4 also the Note2 so the pris and cons for each i passed through till am satisfied now with the One.
So first what is UltraPixel. Its a big sized pixel 2 micron which allow it to be able capturing more light than usual. Just for comparison the iphone5s pixel size is 1.5 micron (was adv. As super light sensitive)
Pixels and sensor size are directly proportional the bigger size of both the better light performance. So basically more megapixels (13) with the same sensor size mostly used (1/3") means smaller pixel size so lower light sensitivety and more noisy capture.
Most phone makers to get bright low light pics they raise the iso. Raising iso really gives more bright image but with more noise. So the right formula is to long expose the sensor to more light with bigger pixel size to get the perfect shot.
The draw back is the long exposure the slower shutter so the more blurred pics you have.
Htc added optical image stabilizer to compensate for hand shakes during longer exposure time to get blur free pics.
So Htc One is getting very near to the perfect formula a bigger pixel size (but same small sensor) with ois and some how longer exposures to get a better low light performance.
So why didnt they put a larger sensor with more pixel and join the megapixel race? The point is a big camera bump at the back as the 808pv or lumia1020 which ruins the beauty of the phone.
Htc one went for fewer pixel to allow a bigger size on the same thin and small sensor adequate for cellphone.
This very long introduction was mandatory just for everyone to know what to read when comparing cell phone camera spec.
F 2.0 means wider basically wider aperature to receive light so faster capture. So now we have a device with
Ultra big pixel f2.0 and ois
With my trials with the one to get the best pic i found that it works best with touch to focus
So just touch the area you want the phone to focus then tab the shutter button.
I found that the phone uses a matrix or centre focus metering mode by default. So you may find your self getting a very bright over exposed pic. Just touch to where you want and the metering mode will turn to Spot meter mode. Example is the lamp pic. First the phone used a centre weighted metering mode but to spot the lamp i touch to focus the lamp and its clear now.
The htc one flash is amazing. Its the only flash i used in phones that preserve the human skin tine perfectly not blue washed as samsungs or yellow washed as iphones. Try it and u will be amazed.
The flash is very strong really strong u may say double the S4 power! It never failed me. (But no near to xenon)
The Night mode in the htc one apply longer exposure time and lowers the iso to get a perfect clear bright night shot. The only draw back is u have to be steady even with the ois and be sure to touch focus on what you want and notice the focus. .. once it locked correctly press the shutter.
There is also l0ck af/exposure feature. Long press on area and the phone will lock the focus and exposure so you can talk dramatic nice shots!
The htc one captures videos @60 fps i dont know why all reviewers dont mention it while they mention it say for the note3 as a premium feature! The htc one captures 720p @60fps thats a very fluid hd video recording try it.
I like how they decided to go 720p instead of the 1080p for the @60fps cause the file size for the 1080p will be amazingly huge that u may find your self filling your 32gb version in alittle period if time.
The hd recording is just fine plenty of details and balanced video file size.
So the point is touch to focus then the shutter.
In video mode the focus is locked so to not let the phone hunts for focus every now and then. But if u want to let hunt for focus turn this feature off (not recommended in low light)
ironically the reviewers when comparing with other phones the point the device to focus during video comparison and sure its locked by default then they say mmm... Failed to focus bad camera ??
Other reviewers take a shot in dim conditions and say mmm.... The one didnt light up the scene as phone x.. . Thats because pointing the phone into bright direct point turns to spot metering it and dims the scene down ... ?? why you dont just touch focus and see the magic! I dont know!
Here is some pics i clicked hope u like it. Feel free to correct/add any part ?

All Default / Just touch to focus Once locked perfectly i tab the capture.
The Boat/Moon photos are Night Mode with touch to focus (5 trials were made to get the perfect focus)
Another perfect shots are found in the other thread of sharing the one photos.

You forgot to mention all the people with defective (or so we would hope) cameras. Some issues include: Purple tint in the picture, noise, inability of the camera to focus in dim settings, inability of the camera to focus at long distances, inability to focus on one side of the picture, inability to stabilize etc.
Moral of the story: if you are extremely lucky, you can get your hands on a perfect One and you'll have a great camera. For the rest of us, nothing has changed.
And does it record at 60 fps by default? I thought you had to select Fast HD from the settings for that.

the camera sure will not focus in pitch black cause due to the lack of auto-focus assist light
and yes in very dim conditions it takes many trials about 5 times to get the perfect focus point.
up in the boat pics my previous S4 failed to focus. it focused only after many trials on the moon.
Sometimes it focus automatic but you will have to re-focus again by touch focus. thats too in all cameras. All this issues in dim conditions not in bright light.
the purple tint i saw some sadly affected with it and heard that in the rolling out update 4.3 will be fixed. And yes my screen turns Red when i cover the lens with my hand.
No the 60fps isn't default but its very nice to have it specially in sporty occasions that needs fast buttery smooth HandyCam video recording
Fast HD (60 FPS 720p) is not enabled by default.
My thoughts?
IMO HTC One has a great macro shot capability. It also has an amazing HDR capturing ability. Using it during low light conditions also sometimes gives amazing shots. Everything else for me is decent.
is your camera settings set to default or customized some ?

Browski, I'm not exactly sure if you're trying to insult me, but it's not going to work. I realize that no camera will focus when there is no light. I'm saying that my camera, once in a while, simply refuses to focus, even though the lighting is somewhat decent. I'm not saying that you are lying or wrong. I'm just saying that it's apparent that not all One's created equal and therefore not everyone will be able to get the same experience as you did.
People in the Taiwan forums and those with dev editions have confirmed that the 4.3 update doesn't fix the camera tint problem. Go figure.

Hey! Why should i insult you or even be rude! We r just discussing a simple point dont get the point wrong here.
Am sad you got a defective unit i think u should return it if the tint bother you alot.
Other people here in xda confirmed the purple issue gone after the 4.3 update ... I will get u the link.
Wish you best of luck. And i didnt made the thread to say that the purple tint is user fault am just trying to help other users with a simple info or trick for better photography.

The issue with the purple tint is the camera software telling the camera to crank up the ISO and exposure automatically.
It's possible to keep the photo ISO down and there's no purple tint. But when recording video there are no manual settings options other than changing the resolution. Cinedroid sort of allows you to manually override the exposure level but the ISO is still maxed out so the image is underexposed but the purple tint remains and the image doesn't look anywhere near the way it should look as if it was a photo.
So a software update should be able to fix it.

Start video recording , hold on the spot you want to picture so you lock the focus then turn off recording and snap the photo ( remember don't touch anything after stopping the recording ) keep in mind this can mess things up sometimes and make super bright photos.
Here's one tip for far flash photos :
Increase exposure , if you use max exposure you better be 10/15 meters from the target , flash is very powerful with increased exposure , especially if using max , it performs like it has xenon.
If using max exposure + max contrast you better be 20+ meters away it's even more powerful.

Is it so difficult for a developer to make a tweak to give us flash when touch to focus? This is the biggest problem of the camera in my opinion as I never had purple tint

JIAYU S3 focusing problem

I would like to know from another owner whether he faces the same problem with this phone. i wonder if this problem has anything to do with the sony sensor. or is it a malfunction of my own phone.
The problem is taking pictures in (low ?) light, indoor conditions. If I switch off the flash and try to focus, that is touch focus on a close piece of text such as , a fine print on a prescription, the camera will just not focus. I wonder if anyone else has faced the same problem.
Perhaps some other owner can do a similar test and fault their feedback here Now if you turn on the flash in low light conditions , I mean indoor conditions (they are not really low light,) then with flash on the pictures are nice..It leads me to think that in low light conditions the camera depends on the reflection from flash to achieve good focusing.
When I use an iPhone 4 in similar condition the iPhone camera will focus
Very precisely without any flash. the Sony sensor here is IMX215 and the iPhone 4 has an Omni vision ov8850
Please let me your thoughts

Try to use camera mx from playstore
I'm already using other camera apps that offer a lot of options in terms of focusing but the problem is the camera itself will not focus up close unless flash is turned on . If you have the same camera can you try it at your end and share your results - switch off the flash and focus on small print in doors and tell me if it focus correctly

It is happening to me too. I think it's a software problem, not a hardware one. Let's hope that the stable lollipop will solve this.
If I use this app open camera then I can get slightly better pictures without flash in low light conditions for close ups by changing the various focus options
So I do not expect it to improve w lollipop .this is the limitation of the camera under low light conditions . They use a good sensor but just standard or possibly substandard lens so the full potential of the sensor cannot be exploited.
buying the cheaper Chinese brand cameras get you compromised someplace . If they do a good job and sensor they will short on the lens. Xperia cameras have the g lens from sony and I think that makes a good diff.
For this one I think when the flash turned on it uses the flash to focus as well so without flash it relies on passive light coming and so the focusing is not precise . Why can't they just charge 50 dollars more and put in a class lens to match the sensor.
Anyways do you have a place where I can upgrade to lollipop. I was looking around for lollipop rom

A better camera app?

First day with this fabulous device. Came from Note 7. The only disappointment so far is the camera, especially low light. I'm wondering if it's just the app itself. I downloaded LIGHTROOM and I'm getting better results but has anyone found another camera app that works well?

"A Better Camera" seems to take better quality pictures in low light (just testing it at my desk). It crashes on setting image size in the setting though (but not from the in app menu).
However, it's video function doesn't let you set resolution/rate and such like the built in app.

1) As a general point, low light photography is the weak point of the Axon 7 camera
2) You can try open camera. I have had good results. It is a free open source app
One thing i found just by mistake, was if you tap on where you would like to focus in low light conditions it will turn on nightmode and give slightly better picture.

Yes, Google camera works great... Not any improvement in quality, but works great. Not like it did on the Nexus 6P (not able to swipe to change from camera to video, have to use swipe-out menu).
If you have the ZTE camera open, then try to open Google camera (or any other), you'll get an error the camera is in use by another app.

You should be able to extract it from any of the stock system partition images -- either direct from ZTE's files or from DrakenFX TWRP backup versions.

The default camera app already has the best options for low light. It's just a trade-off between shutter speed and grain. You can use SUPER NIGHT mode or ISO100 mode in manual to get less grain but you have to hold still to avoid blur. SUPER NIGHT seems to make a composite to reduce blur though.
Any sample shots using super night mode?
Zte is not using the CameraApi2 so you won't get the same quality with a 3rd party camera app.
I've personally found that HDR works quite well in low light, sometimes making the shot look brighter than real life. The only annoying part is keeping the phone steady to avoid blur.

Nougat on Z5 : no more blue tint on edges (camera)

Hi there,
Good news, I have noticed the blue tint on the the edges of the low light pictures is no longer there when using Android 7.0. Automatic mode.
I guess the low light setting isn't too aggressive with the ISO setting now, as was the case with Lollipop or Marshmallow.
Too bad the ISO value is still not displayed on screen.
Not sure what are other things have been changed with the camera software.
Best
MF
I just tried the old firmware about 2 hours when i bought the device , then updated to latest software 7.0
I noticed that with the old firmware , the pictures taken with camera in very low light was more clear than the new update , but not sure because was only about 2 hours of testing.
I have not noticed a difference w.r.t. the picture clarity.
Regarding the blue tint, the difference is spectacular. No blue tint. At all. Take a picture in low light conditions and you will immediately see that. Even if you usually don't care about picture quality. The difference is THAT big.
Pics or didnt happen

Improvements in stock camera app?

Has Moto stock camera app improved picture quality? I haven't updated my camera app for a long time now, even the one that changed the app icon. Are there any improvements after updating the camera app on stock ROM?
Nops only changed the icon and microphone bug. Even the pink tint is still present in high ISO setting. forget HDR+
I think that the quality is little bit better using manual mode.

Agreed. I find setting a manual shutter speed cuts down on the oversharpening that usually occurs with low light shots. I use 1/30 second for most indoor shots. The photos are usually under-exposed and require some tweaking in Google Photos or your editor of choice. I'll take that any day, instead of automatic mode's tendency to over-expose and clip the highlights.
I've got to admit, I just got this phone today and was hoping it would be at least as good camera-wise as the Nextbit Robin it was replacing. I didn't think the Nextbit's camera was so amazing, but with the right manual controls I was able to nail decent shots with it.
This, I feel like the colors are oddly oversaturated and the sharpening is ugly as sin. I did also find that switching to manual helped a bit, at least with the sharpening, but what's with the clipping highlights so early? Does this camera sensor just suck when it comes to dynamic range? Or is it just bad software?
My phone hasn't had a chance to update yet so I was hoping new software might have come along to address the shortcomings, which is how I ended up in this thread.
Are there other camera apps which might improve things? I tried Open Camera, but it seems to just behave the same as the stock app with a different UI. Has anyone tried the ported Google Camera app?

I'm resurrecting this thread in order to address your original question, which is now irrelevant to you. Meanwhile, you've demonstrated (in this thread and others) that the G5+ does, indeed, have a capable camera module that's hamstrung by lousy software. But this is for those of us who are still wimps and not yet willing to unlock the bootloader.
As others have said (and I have too) just switching the stock camera to "pro mode" seems to reduce the oversharpening effects, but only slightly. Setting the shutter speed to 1/30 also helps in some low light situations.
However, my best luck has been with the Camera FV-5 app, which I bought years ago. In addition to allowing much more manual control, it also can be set to save images in .png format, and that seems to bypass more of the default image processing. (Unfortunately, it also means no EXIF data, so no info about exposure is recorded.)
Setting Camera FV-5 to save black and white images (Settings/photo encoding settings/color channels) also produces some strikingly sharp images that I find very pleasing. I'm sure many will not be interested in that option.
Am I the only one who finds it hilarious that Moto is now advertising the G5+ as having the "Most advanced camera in its class"?
One more app worth trying, whether rooted or not: FreeDCam. It's free and open source. It's possible to turn off denoising, resulting in a much sharper image. Some sort of noise reduction is still needed for most low-light images, though. Even without root, I'm getting much better photos now. For those who are rooted and have access to camera2 api, raw images are supported.
edit: after more experimentation, my enthusiasm for FreeDCam is waning, at least on unrooted phones. I think it still has a lot to offer those who have rooted. And it still produces incredibly sharp images in good light. But in low light, the noise is severe and I haven't found an effective way to deal with it. For now (until I root) it's either the stock camera in "pro" mode or Camera FV-5 for low light shots.
I was disappointed with the camera too when I first got mine, but I've recently discovered it's not the camera itself, but merely the software. I've been using the 3rd-party, free, ad-free Open Camera app by Mark Harman, available in the Google Play store, & it's heaps better! You can download it here: https://play.google.com/store/apps/details?id=net.sourceforge.opencamera&hl=en
