Back camera is pretty good in daylight condition, although it doesn't perform well in low-light / interior light conditions.
The problem is front camera. It is very bad for a 2017 middle range phone!
The color is brownish and the photo quality seems to be too compressed. I hope is a camera driver / firmware issue

I do not care for the front camera...

Camera Fix for the HD

I searched for a camera fix for the HD camera with no success. Does anyone know if there's going to be a fix in the near future? I'm sure that ya'll have the same problem that I do. Camera takes pictures that look old & rustic. Brownish tint to them & not very sharp for a 5 MP camera. I have adjusted all the settings for light & junk but nothing fixes it. As far as I'm concerned, it should take pictures IDENTICAL to a normal 5 MP digital camera. I can promise you that it's not doing that. Any help would be great, thanks in advance.

Why should it take pictures identical to a 5MP camera. The lens on the front is going to be vastly different, the sensor maybe 5MP, but what is the spacing on the sensor pixels? The closer together, the noisier the image. Colour balance will be down to the sensor too.
Regards
I'm not talking about the front camera. The normal camera on the back. I understand about the pixel thing, but it still shouldn't be so brownish, right? The pictures look like an old Polaroid picture. You know, the one's that spit the picture out as soon as you took it. Old, brown & nasty looking.
My pictures come out fine...
Hmmmmmmm...................... I'll just keep playing with it.

I'm not being flippant, but is it possible you might have a dirty lens?
Lol, that was the first thing I tried. Cleaned both sides of the back cover & cleaned the lens on the camera. Good idea, though.
The "5mp" doesn't really mean much, as stated earlier, if the sensor and lens are poor quality. As far as I know, HTC haven't released a phone with a reasonable quality camera, yet.
I bounce between different smart-phones (just coming back to WM now, after a year with S60). I can say that many of the S60 devices (in particular the Nokia N95, but also the N82 with Xenon flash) have very good cameras, being similar to low-end digital cameras in daylight. They lack optical zoom and tend to over-compress images, but have good quality lenses.
imho hd camera is excelent
pictures look old & rustic only if you make them inside house without using the artificial light setting, and this is also a general rule, not specific to HD.
Never seen a good phone camera yet, including the latest 8mpixel ones. They're all terrible.
Never
This camera will NEVER take pictures anywhere near what real cameras do. The photo sites are so tiny, they are smaller then the length of waive of light. Therefore noise, lack of dynamic width, etc. No patch will ever fix that. Sorry
open back cover , clean the lens , you will see a huge difference in quality

Not that I'm doubting you or anything but you do realize that the back cover only has a hole through to the lens?
You might try setting the brightness higher:
If you touch the small rectangle near the bottom right side of the screen (when holding landscape)
Then select the gear symbol, then select brightness from the menu and hit the "+" until it looks better that will remove most of the darkness.
The camera is a plain disappointment. In the time the camera autofocusses, I could have bought a Sony Ericsson C905's, create a good looking photo (with xenon flash) and upload it to imageshack.
If 'your object' makes the slightest move, your photo will be blurry . This is also the case when you attempt to make a photo of someone that isn't aware he or she has to be waiting for the autofocus lag. Head moves >>> blurry pic.
iPhone camera shots are way better quality, don't ask me why. Overall my Touch HD scores 8/10, where atleast 1 full point is taken up by the camera
and it's better don't speak about the very laggy video recording

Too many megapixels on a tiny sensor = major noise problem = blurring from denoise.
Even 2mpixels is too much for sensors this size, but people buy on marketing numbers of megapixels, not quality. You can just imagine the whining that would occur if the Touch HD came out with 1.3mpxiels, even though it would produce better pictures.

hehe, thats true.
mpixels dont count as much as the general public belives. the more mpix. the higher rezolution you can print the picture in. but for ordinary photos, 1.3 mpix would be enough, as long as the optics is good.
Personally, I rarely use a phone camera.
I use either my Olympus 720SW or Canon EOS.
​
the camera sucks **** compared to the n95 and the video recording is horrid. i know it's not meant to be as good as a dedicated camera but this is pretty bad given the price of the device.
i concur with mach03, move the camera a slight bit and eveyrthing gets blurred. one way i've semi gotten aorund this is to unlock the burst functiona nd take a sequence of pics and hope one or two coems out alright, not the most economic way to do it though...
i would ahve thought that maybe there's a way to tweak the camera to stop the blurring or even affect how much light is picked up by the lens which should also help with clarity

A silly idea, but seriously, did you check if maybe, just maybe, you left the "sepia" effect turned on???

Poor quality front camera

I noticed that my new TD2 has a very poor quality of the front camera compared to the D1. I don't know if it's faulty, but it looks like digital zoomed, even if settings are superfine and L size.

It's just a crap camera... that's all. You wouldn't need a better resolution for video calling anyway. If you really need to make loads of self portraits, then rather find a friend.

LOL !!
But I think that the back 5mpx camera is crappy too... (compared with my old Nokia N95 classic).
If the ambient light isn't PERFECT, the camera is useless...
Front camera is a VGA (640x480) CMOS unit with no zoom capabilities; It will look blocky on almost any screen nowerdays (It's even lower resolution than the screen on the phone itself). As for the rear camera being worse than the N95 classic, the N95 was fitted with Carl Zeiss optics; Specialist lenses for cameras, and fairly good quality considering the market. It was (and still is) a very good camera phone. HTC cameras are *notoriously* bad. Autofocus is great, but no use without a decent CCD and optics. Heavy blurring under motion and poor ambient light handling are typical issues. The trouble is that HTC don't make camera phones, they make PDAs with camera and phone capabilities. Still, it's better than the iPhone...
If you want a decent camera above all else, send your phone back and get either a Pixon or any SE phone / Nokia N series handset.

OK I know that... but why make a phone with *5mpx* camera with crappy lens ? Why don't make 3.2mpx camera with good lens ? Just marketing ?
And I`ll pay some extra 20$ for some LED flash too
Wait.. I said so 'cause the front camer on Diamond 1 was waaaay better!
This one looks ugly, dark, pixelated and zoomed. Just sh**ty!
I was supposing that it's kinda faulty. I would try how it is after a rom upgrade... atm still stick to the rom in signature.

Samsung Galaxy S5 front&back camera issue

I have a Samsung galaxy s5 and I'm having issues with front and back camera, the quality is too low same in the back and front camera I'm even getting watermarks on the front camera as you can see in this photo. The phone is not fake it's original the screen is quite scratched and the back camera case is also very scratched but I don't really think that's the reason I'm getting the quite-like 3mp camera quality lol.
Is there anyway I can fix this?
Marks on the camera lens would cause the spots all over the screen, they'll likely be tiny and maybe hard to see on the lens
Have you set the MP quality to max in the camera settings? (Cog at the top of your image)

Yes of course I did, it's 16MP.
I don't get the watermarks on the back camera, only on the front one.
The phone also has one problem: Sometimes it turns on normally, the sound of booting can be heard but it doesn't show any sign on the screen. Can this problem be fixed without changing the whole digitizer?
Well that's pretty obvious, if there are watermarks using one camera and not the other, then there are watermarks on one camera lens, and not the other... (Or a faulty front camera)

Is the front video supposed to have really low exposure?

For some reason the exposure on the front camera is really low. When switching back and forth from selfie mode and video mode there is a huge drop in exposure, compared to the front camera where there isn't any difference at all. Looking at all the video tests for the front camera on youtube, they all look fine in comparison. I can't tell if this is a hardware defect or if the front video camera on the axon 7 isn't that great. Anybody else have this issue?

Hi, I have the same problem at low light but it's fine at good light condition. It seems that the back camera automatically adjusts the exposure at low light, but the font camera does a bad job. However, you can manually adjust the exposure thorough the vertical slider on the right. The algorithm of Axon 7's camera sucks!

I know what's wrong with g5plus camera.

The highlighted thing about g5 plus was also the reason for bad camera. The 1.7 aperture and wide angle camera are the cause here. Though it is good for shots within a certain distance like 10-15 feet. But any further the pictures loose sharpness and gets noisy due to which moto decided to use high denoising due to which the photos look soft. My father's redmi 4 clicks better distance pictures than this. It has 2.0 aperture and little less wide angle lens.
Don't forget that G5 Plus have the same camera sensor as HTC U11 or Asus Zenfone 4 (which takes good pictures on stock software).
Worse photo quality is caused by software (Motorola/Lenovo screw it up).
Did you tried any mods/apps? You can find a lot of these, but I suggest you to try Google camera app port.

I use bacon camera on stock Android without root.
I disabled noise reduction and use hdr with manual mode and stable hands to get though grainy but nice pictures. Though the app is not perfect but it works
When I first got the G5+ I thought the camera was too dark... While a lower aperture may help in low light shots it does cause a bit of trouble for highly illuminated scenes.
HDR does compensate but it's nothing like HDR+ from Google.
Plus, terrible sharpen and overdone Noise Reduction excessive Color NR.
I felt quite dissapointed comparing it to my old Titan (G2)
Anyone tried to mod the camera to enable debug mode? You can disable noise reduction from there

Coming from an old school enthusiast of photography background - you're aperture on your lens (in this case f1.7) isn't going to cause noise - that's a function of the sensor. A lot changed when we went from film to digital sensors, but the impact of the f number of the lens did not.
You might be on to something with the with loss of sharpness though. Typically a fixed focal length lens is at it's sharpest at it's only setting... but they very well could have forked this up.
Given that the camera does pretty adequately with other camera software or other hacks - I don't think it's a hardware issue or lens issue. It could be a cut rate sensor...
It could also just be that whomever chose the default settings for this camera did a bad job

What about shadows in bright scenes such as outdoor scenery?
I mean, wouldn't lens aperture like f2.2 preserve more of these details?
That's a function of the film/sensor.
Your f number controls light and the depth of field (area that's in focus) - a smaller f number is more desirable because it allows more light to the film/sensor.
The only thing different here than fine that I can see is the size/diameter of the lens related to the f number. A larger f number, like f 8 or f16 increases the depth of field and sharpness, but at the cost of light hitting the film/sensor. That results in a longer exposure time.
A wide open f stop means more light and shorter exposure times.
One thing we gained with sensors over film is a wider range between highlights and shadows... You could get more shadows and more highlights. Film could get only so much of that before shadows went black and highlights blew out to white. But you still have a limited range. You can't get it all. In order to keep the highlights from going completely white you have to trade off some of the shadow range.
It's early and I'm probably explaining this horribly. Your spectrum between black and white or shadows and highlights is very long. But your camera sensors capability can only encompass a range of that spectrum. If the spectrum were a line of shades of grey from black to white that was, say, 10 units long, the range you could get in one image might be six units long. You've gotta give up somcombo of four units either at the black end of the spectrum or the light side.
If the cameras loaing details in the shadows that's because it's opting to the highlight/light end of the range.
So lens doesn't play a huge role in what chunk of the spectrum the film/sensor can encompass. But does play a role in how quickly the sensor can collect that info. Higher f number = smaller amounts of light on the sensor = longer exposure times.
My guess would be that the sensor or software is biased toward highlights because it results in faster exposures making life easier for snap shots and selfies.
