Bad pixels on photos taken with Universal - JASJAR, XDA Exec, MDA Pro General

Hi!
I have problem with red, blue and white dots on every photo taken with my
universal...
Here you can see:
How can I repair my camera? Or where I can repair my camera? And
what is repair cost?
THX

You will probably find they are "hot pixels", which are pixels always stuck on a bright colour (usually white or light blue). These are flaws in the sensor and can exist even on high-end cameras. You could replace the sensor, but to be honest you may be better just buying yourself a cheap camera.

Hmm.. I have another camera I want to use my universal as alternative, when I can't take my compact camera...
Where can I buy that new sensor? I can't find any on ebay...

Having looked for HTC components myself they are practically impossible to find. I doubt you would come across the components you want unless you salvage them from an old Universal.

That you having is called nose in professionals photographer terms. It's a peering wan you sensor is exposed to high sensitivity.
I phased same problem wan i updated form WM5 to WM6. I think it's a gun in some Bootloaded OS. I went ban to WM5 and it was fine. I'm running WM6 now and truing to fix this problem.
And one more thing take photo with low resolution like 640x480 and if you not going to have this problem it's a OS bug not Camera. lather a voltage to high or ISO it set to high

Camera quality? Different leneses?

I have an Cingular 8525 and two of my buddies have another 8525 and a softbank X01HT. Why do my pictures suck in the dark and there's don't. They have the same good quality in the dark while my pictures come out very blurred and dark. I checked the adjustments and they were the same. Me and my friend both have the same rom on the 8525 and everything! I don't get it? Did HTC start shipping different lenses after time? Has anyone else noticed this?

My Tytn is not good in the dark. I doudt there is anychange in the lens but there may well be a difference in the auto light level increments. Before you ask how you could change that - I don't know. Don't even know if it's possible.

I dont believe that this is caused by lens. maybe version of Camera program is little bit different or some DLL file (but you said, it is the same). anyway you can compare it or try version from Trinity (it is here somewhere) but this version have not comfortable installation and do not support front camera and light I guess. But if your device is newer like the others, then maybe HTC used different (and perhaps cheaper) CMOS chip - I dont know, it is only speculation, but it is nothing unusually when electronic company uses cheaper components in newer pieces.
Ill try to get a picture so you guys can see the difference and what I mean. Adjusting the settings does nothing, in fact, it makes it worse for mine...

That would be interesting to see. It's not that we don't believe you, just that we don't think it's the lens that is different. My Tytn as I said above is very very poor at night but great for sunny day photos. I think in my older Tytn it is set too low for light exposure. It seems to adjust itself in incremental steps to the light level but in dark conditions it does not give nearly high enough a light exposure level. It is entirely possible in later/different models this hard coding has been adjusted for better results.

Ya, I just want you guys to see it. It's not a minor difference. Mine is so bad I don't even try to take photos at night, while my buddies' has unbelievable night photos...damn htc!

I feel your pain, I have this problem with mine (TyTN) too. It takes really bad pictures in dark areas, and most pictures look too dark and blurry even when there is a decent amount of light. I saw many cheaper phones doing a much better job. Really a shame.
My htc tytn also takes crappy night pictures. the front camera takes better ones at night. hell every other cell phone i had in the past and all of my friends phones take better night pictures.
very lame on htcs part.
is there a way to change how the camera detects light in video or still mode. the camera keeps adjusting to much during different contrast of the back ground that is being recorded
with a well lit area. i would like to sample the light of one area and lock its exposer time permanently.
Could it be software related? I mean, i've installed now Black Satin and i have the impression that the photoquality has gone down in the dark compared with the Black Dymond release. Or am i just imagining things?

[Q] Galaxy S I9000 camera lens flare normal size?

Anyone else noticed some kind of lens reflection problem at night photos?
Hope it's not design fault.
There's no scratches at lens and phone is only two weeks old!
Sample pictures attached:
Edit: yes lens flare is norma, but is it really normal that effect is so strong?
Take that same exact picture with a real digital camera and compare it before posting up another "issue" thread.
Seriously, people are picking straws now.
That's a known optical phenomenon which is called "FLARE". edit the title, this might get people anxious.
Lens flares is a problem optics struggle with. Even 1500 dollar lenses fail in this. But with special coating and sofisticated technology it can be less flares.
The only real solutions to prevent flares are:
a) dont point the lens to a direct light source (like the sun)
b) use a lense hood (on a phone?? hehe)
But you can in fact use your hand to shadow the lense to prevent this.

digital-photography-school.com/eliminating-lens-flare
My take on this:
Since night mode compensates with high ISO, it will get those lights more. Try covering the bright part.
This is absolutely normal for cheap camera with a very small lens and plastic cover.
high iso wont likely give you more flares, just more noice. Unfortunatly with almost all but real slr´s the software tries to hide this noice with cheap and lousy smooth-filters, creating a soft and cartoonish look

Front Camera Low Light Pink/Purple tint..

Anyone got a purple overlay on their front camera when there is no light?
I get heavy purple or blueish vignetting with the front camera in low light, but only with the stock camera app.
First pic is from stock app, second one is from Google Camera.
Does anybody else see what Fuzalert2k sees when the camera is covered, i.e. dark? That means the image enhancement algorithm goes crazy in low light conditions. Does your camera work normally otherwise?
PS: there's already a thread on this: http://forum.xda-developers.com/z3-compact/general/camera-pink-spot-poll-t2933507/

Yes, the purple hue is also apparent in not-so-low light as you can see from my sample.
No, it's not the same phenomenon at all. This effect is only visible in the end result picture and it's the entire picture rather than just a spot within it. This is also not related to white balance, just seems to be a problem in the post-processing of the stock camera app specifically.

Yeah definitely not the same thing.
Look's like I'll be using Google Camera in future.
I must say Sony really dropped the ball on the Z3C camera software, and have yet to fix it or even acknowledge it.
I come from the HTC One.
The "pink hue when dark situations" was a well known problem there.
For soem time HTC used faulty camera sensors, which caused this problem.
If you experience sthis problem with your HTC One you can send your device in and get a replacement.
I hope that this is not the same wit the Z3Cs.
I for myself can't reenact this behaviour with my Z3C.

You are trying it with the front facing camera, are you?
It wouldn't make sense if it was a faulty sensor because it only happens in the stock camera app.
Now went into a completely dark room.
You are right, with the front cam, there is little bit of pink hue on the edges.
Yes, it is very "good" that it's only visible with the stock app.
Therefore the sensor should be okay.

V20 Bug - Purple Shadow when Taking Night Pics with Wide Lens

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?

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.

Moto G7 worse the G6 phones?

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.
