Or am I wrong?
I had a demo unit in my hands today... I tried to play with the camera.
Changed it from center weighted to spot meter to find out it only measures the light value from the center (aka center weighted) no matter where you press to focus. My old SGS1 would spot meter on the focus point while the SGS3 and SGS4 don't do that.
Sigh... to have the uber best camera on the smart phone market and not have decent spot metering is just retardulous.

figured i'd start a thread on the use of the camera and what others have done or do to take amazing pictures. possibly post some
only thing i've noticed is holding down the camera button half way till the center cue comes up and beeps, to snap a shot allows for a lot better clarity and focus on a shot.
that is the focus .... setting the anti shake before taking pics helps too. the use of macro mode helps with the small items... also adjusting the metering can help when you are shooting something and the light is coming from an odd angle...
ah k. Kinda assumed it was since pics are taken instantly with the push of the button instead of typical 2-3 sec delay to focus as with other phones. Have to mess with macro or any other feature other than image filter for b&w shots. Will try it though.
samsungs always take great pics.... i wish this phone had the settings the omnia 2 had.... that camera was the best 5mp out...
i wonder what Nokia's partnership with Microsoft and Windows Phone 7 will bring as far as cameras, cause honestly the last great cell phone camera i ever used was on an old Nokia flip phone from T-Mobile (years and years ago). it may have been 1.3MP camera but it took some sharp pics and quick. Iphone was eh aight, blackberry curve..the led flash was too long too bright and pictures were grainy, HTC Tilt 2...so so quality with slight not so noticeable color tint. but this Focus phone takes better pics than my old 8MP Nokia digital camera.
Was playing with the different camera modes the other day when my camera started acting funky. It looks like its out of focus but upon closer inspection i noticed my lens is actually moving around with the image stabilization. Pictures from far away arnt as affected but anything within 10 feet just comes out blurry. The picture also looks like its jumping around when your lining up your shot. Tried resetting the camera settings, manual focus and even a 3rd party camera app with no change. Was wondering if anyone knew of a way to disable the ois, or fix the problem all together?
Loved this phone but its just one problem after another, might just jump ship soon.
i think your camera focus is broken , replacement costs ~15$ on ebay ...
mine also won't work correctly, it's like it's in macro mode , i removed battery cover and pushed lens with finger and it focused on far objects . so this means focus is not working
Its the optical image stabilization not the auto focus. I can see the af trying to correct for the ois but the lens is constantly moving really fast making the picture all jumpy.
I can physically see the lens moving back and forth about a 32nd or 16th of an inch constantly
Hi Everyone,
Have a look at attached example image to see what I mean.
Please try to take a manual shot with your wide lens in a very dark environment with very high ISO (3200 in example) and exposure time of 5secs plus (20 secs in example).
Everyone who has tried that so far has the same issue, a big purple shadow on the top. It's most likely the laser and it won't happen with the normal lense.
Do you have the same result? Any suggestions what we can do about it?
Whoa! I haven't seen that in a long time. I think maybe around the time of the Nikon D80. I can't currently try this out personally but by the sounds of it what has happened is called Amp Glow. It's when you kind of start getting out of the bounds of what is really acceptable shooting conditions for a given sensor. In this case, if you really are shooting in conditions that call for high ISO AND still need a shutter speed of 20 seconds and the image still comes out that dark, then you're way beyond realistic expectations for shooting with a cellphone. In the older DSLRs, people would see it when doing star trail photos that were 10 minutes or longer. Frame stacking software became the solution to this problem by taking a lot of shorter photos and stacking them up and pulling through the new dots of light. (And this is still used by a lot of photographers as it also gets rid of other forms of noise.)
So what is happening? ISO is pretty much the gain. It's the amplification being applied to the signal coming off of the sensor. Ideally with ANY camera, you want to stay as close to the base ISO of a given sensor. That's usually the lowest ISO number. (There are some exceptions where some camera manufacturers have done some trickery to get a lower ISO to show up but that was short lived as it didn't really help things.) Unfortunately, image sensors are not hanging in space. They're packed in with a ton of other stuff. Stuff that gets warm. If that stuff is near an edge of the sensor, that heat bleeds into the sensor and then those warmed pixels get amplified by the higher ISO and next thing you know, Amp Glow. Well, that's the simplified version at least.
A cellphone, any cellphone, is not designed for those kinds of shots. If they were, they would have a tripod mount, a much better flash, and a much larger sensor. (Yeah, the flash on your cellphone is not meant to light up stuff much past 5 feet. Even the ones built into a DSLR aren't meant for much past about 15-20 feet.) The reality is that cellphones are designed for handheld shots with decent light. Even the larger sensor used in some cellphones shouldn't be expected to pull any miracles that top end DSLRs are just barely pulling off cleanly. For that shot, you would want to use a dedicated camera locked down on a tripod using base ISO and long exposure at the very least. Although, personally, I'd probably just take a pass on that shot.
someone on reddit has the exam same issue with the wide angle. and someone said it's in the regular too. weird. my s7 never had this purple hue when I did even 30 second exposure at night.

something obstructing the lens maybe, or just camera went bad
Better hope this isn't the same problem the HTC one m7 had with the purple haze. The culprit was a light sensor on the camera would overhear and give a purple haze on the screen in low light. Place the phone face down and with the camera on and see if the purple comes back.

No, it won't happen with the same ISO/Shutter settings I took the previously attached photo. But maybe that's because it's not dark enough. Did the M7 issue only happen in dark enviornment as well?

Thanks a lot for the detailed explanation. My question here would be, why doesn't it happen to other phone-cameras with similar settings?

Yes the m7 only happened in low light / dark environment. Do a Google search for HTC one m7 purple haze. What caused me not to buy another htc phone

Settings aren't the only part of the equation. The other par is the placement of other components within the device. I need to look at the tear downs to see how the various parts are placed next to each other but something is heating up and passing that heat to the sensor. Just off the top of my head there are four parts together; the two camera sensors, the laser focus module, and the flask module. Each one of those on its own will generate heat if used enough.

It's the same issue. I haven't looked at the HTC issue but from your description of it, it's the same. Amp glow is what it is called in digital photography. (OK, silly that I said digital as you don't get amp glow in film.) The glow will show up because there is no other data coming off of the sensor for those pixels and the heat is amplified as "data".

Ok, just watched the JerryRigEverything repair tear down. The flash module sits right next to the wide angle and the laser focus next to the regular sensor. There is no mention as to what is sitting next to the sensors on the main board but I see silver boxes on each side with one having some sort of black and yellow warning sticker. Not sure what they are so I can't rope them in as culprits. So for now, I'd say it's a combo of the four units of the camera assembly.
Were you running the flash or one of the cameras a lot while you were playing around? Shooting a lot of long exposure shots in a row?
I'll get to test out some night shots and video tonight at a lighting ceremony but I'm still not expecting to shoot 3200 for 20 seconds type shots. Again, that's pretty extreme.
Hello, I think my S7 Edge camera has a serious HDR issue especially in the front camera. Whenever there's a little light coming from behind (while taking a selfie), the camera just turns black and I can't even see my face even during the day. The same issue is with the primary camera. I was lying down on the couch with my iPad reading my research work on my lap, I wanted to take a snap of the ceiling as I was laying down, so I opened up the camera and the ipad screen happened to peek in a little bit(the brightness was a bit high on the iPad) and the camera again turned completely black, so even in a well lit room it was like all the lights were dimmed completely. I have attached the photos of the same.
First photo is the issue I am talking about. And the second photo is of the actual room without the ipad screen.
Please help me out here. Is there some app or tweak that will force the camera not to do this? See I love this phone a lot and been holding on to it since it's release and I don't wanna switch phones just because of the camera but I am really frustrated with this issue.
I have some concerns about the new Motorola G7 phones particularly:
Screen - The screen tends to have a blue/cool tinge, the overall display calibration is "off".
Camera - Colours can be washed-out, zoom has many artifacts & noise and poor dynamic range at night. Stabilization needs a lot of work (for both front & back) and overall sharpness/detail/colour could be better.
Does this mean the actual lens is of inferior make & quality?
Will a GCam port be enough to compensate for the otherwise poor camera image quality?
Need help. Thank you.
Unlike G6 and Z3 Play, you cannot change the color temperature.
However, you can install CF Lumen if yours rooted.
I did it on both G6 (compensate green) and G7 to keep the color temperature consistent.

For the screen, I usually use night light. Corrects it easily
I know our maintainer is working on a gcam port last I knew. If you have twrp you can always flash gapps with gcam
But to answer the thread title: no its not worse with more RAM, more storage, better SoC, etc than the g6

I haven't noticed where the screen seems to be blue, mine looks fine to me and other colors seem just fine.
As far as zoom goes this device does not have optical zoom, so of course it's going to be bad. May as well take picture normal then crop, it achieves the same thing. I think stabilization is amazing, definitely a lot better than the G6.
I use the Google Camera port and it definitely takes good pictures but I haven't noticed and differences between them. Night sight is amazing too.

I have a replacement screen and the video looks fabulous over my g4. That died. Get a case or you're going to be looking on eBay for a picture of the exact same ribbon cable printing for about 29 bucks. If the photo doesn't show same printing on the black, don't get it! Real on left, not gorilla glass 3 on the right. I used silicone on the very edges instead of getting that 3M stuff because this model of phone uses the REALLY thin stuff. Did my pic upload?
Absolutely NOT! I feel as though the G7 is USA's G7 Plus with those specs. Lenovo really screwed up not bringing the G6+ to the USA last year. My OG Pixel was trashed (throwing it at a concrete wall) and my closest option to purchase an Unlocked Device was at Walmart. All the devices they had on display were last years models and the very non-knowledgeable sales Rep didnt know what was in stock, so i said forget the display models and lets head over to the storage box and see what there is to choose from. When he opened the box, a bright light shined over and they're were about 8 G7s (non of which was on display). "Oh we cant sell them yet" WTF??? Go I got stuck taking a G6, but I was NOT a happy customer. Contacted Walmart Customer Support and 2 days later i returned the G6 for my awesome Moto G7.

I do repairs so I see complaints about color accuracy on devices all the time, but you can take devices straight out of the box and there will be variations because there is an acceptable tolerance otherwise they'd be throwing out so many screens. The ones that tend to get the most complaints are the ones at the edge of the tolerance.
3m tape is awful for screen replacement, we use the black Tessa tape, it's super sticky and doesn't like to let go.
