Are they in the same place in every photo you take?
If so it looks like you may have some kind of contaminates on your lens / sensor.
I'd send it back to HTC and they should fix or replace it for you.
If it was a DSLR you could use a Rocket Blower to try and shift them but I don't think it would do much good on the tiny DHD camera

yes they are. i'll send an email to the shop i bought it in and hear what they say about it

Most likely dust on the sensor. Was it like that when you bought the phone?

Usualy dust on the lenses appear as bigger blurred spots. Those sharp edges on the black spots should mean that there is something wrong with the sensor (dust or a faulty sensor). The fact that they appeared at a later stage is truobleing - it could mean that the sensor is not sealed properly. Have you tried to take a picture at a bright light souse (a lamp for example) to see if they are still visible. If they are that should mean sensor failure. Are they visible while taking the shot or while shooting a video?
Anyway, you should take it for repair, they have to do something for that, but if you are rooted, S-OFF and/or have installed custom ROM, be sure to return your phone to stock condition, because they will void your waranty if they see you have done these things to your DHD.

Hi,
Any news about your problem ? I have the same kind of spots on my Galaxy S and would like to know what causes it...

Hi tkolev! Thanks for the precious info. I have a similar problem with my camera. I see a black patch on a fixed position in images as well as videos. Its just there when I turn my camera on.
Here's my thread.

FYI When i focus it towards a bright light source, it disappears..

Bottom Button Light Alignment

So, I just traded my Galaxy SII for a One X on Craigslist. He told me of this problem before, but hey, I didn't care. The phone functions perfectly fine. The one issue that I'm just annoyed at is the bottom button alignment. I don't know if this is common or not (I tried finding other posts but I didn't find any), but the lights behind the buttons are a bit to the bottom left. But when I press the buttons, they respond, the lights just... aren't behind it? Sorry, I don't have a great camera (used my Captivate) but I tried my best. It doesn't seem prominent, but it really is in the dark. Is there anything I can do to fix this? Or can I possibly send this to HTC (if I just tell them I bought it from AT&T, I don't know how they would figure out I didn't. I have the original box too)

in my phone, lights are perfectly matched to buttons
well try factory reset once and if the issue is still there then you can talk to htc customer care and send it to them {if the phone is not rooted}

Here is my issue. I already called them and they told me that they could diagnose it and possibly fix it. If I don't want to have it fixed (due to a high price for the services) I am required to pay the $40. So basically, I'm screwed.

Looks to me like the LEDs behind those buttons somehow got shifted. Can’t imagine something like that passing quality control at HTC, perhaps the screen was replaced by the previous owner and whoever responsible did a shoddy job.
Look very closely at the very edge of the screen and the thin black strip surrounding the screen for tool marks. This is how you take off the screen of the One X, the process is likely to leave some marks at the pry points (especially if it was done poorly). If you can see marks, that is a very good indication that the screen was replaced. IMO there is nothing much you can do without taking it apart and re-aligning /replacing the LEDs.

Yep, I just looked and talked to the guy and he said he did open it once. I think I'm just going to leave it as is because the phone functions perfectly fine and I don't even use those buttons that much (I'll just stop them from lighting up with an App). I was also expecting a problem here and there seeing as the phone essentially cost me 160 off contract. Thanks for the help.

[Q] Should i take it for warranty? or is it normal?

hey there guys. am having multiple issues in a 1 week old Note 2 which i noticed very recently.
first issue being , strange fade outs near home button, (tried cleaning screen with everything from water to specs lens cleaner,it's a permanent thing..... and looks like it is under the glass )

Second issue is non-aligned fade outs on front cam and sensor
third issue is , there are few pixels on left side of screen that do not blend in with other black pixels around them(except for videos where color is similar to pull down menu on home screen).it doesn't move either.it's in a permanent location. it can't be seen under proper light and only appear on more or less lowest screen light setting with ambient light off.this issue however doesn't occur with any other color of video,they blend in perfectly.it's similar to note 1's black crush issue,but on a specific spot
sorry but this is the best pic my cam could get. you have to look very carefully
Last issue is, S pen doesn't work on lower right side of the screen. like on the very end in the corner. it works fine in other 3 corners.
I know i sound extremely paranoid.... but i love this device so much ! would love perfection. should i take it to service center? will be pretty darn hard to explain the issues though. and can i expect a replacement ? on the side note, i got it from India and no carrier.
Thank you for reading

Hey,
I dont have ANY sort of fade outs anywhere. You should definitely have it checked. As for the S pen....even mine doesnt work all the way down to the end on the lower right but does go to the end of corners of remaining 3.

+1..definately u got defective one..better change it while still in warranty..

First question, do you have a screen protector on? If you do that will explain everything.
Looks like a misaligned screen protector to me.

guess it's warranty time then
and no ... no screen guard is on.it's whitish cuz of moisture and oily hands,can't help it in India's climate and tired of wiping the screen every hour. but those fade outs are permanent thing.
i do plan on getting screen guards soon after taking it for warranty though.

Is there a hardware issue with the z1c camera and LED flash?

Good morning,
in a german forum android-hilfe.de there is a thread with pictures taken by a lime z1c with led light - all of the pictures have a yellow shine.
For me this looks like an hardware issues on ALL the z1c devices of the first charges but maybe in the black one the problem is not easy to see.
What do you guys think about that?
Here is the link to the thread with the pictures in first post:
http://www.android-hilfe.de/sony-xp...ei-der-verarbeitung-kamera-bilder-inside.html
Could the be a major issue of this brand new device?

GSMArena complained about some issues with their review model. My white one doesn't have any of these issues, seems fine to me

What the !?

I sometimes get a slight blueish shot but that's because of the.auto mode and not a hardware issue. Transfer the image to snapped and increase the warmth. Problem solved

It is a hardware issue. The problem is the back of the device. It reflects the flash light which then hits the camera lens.
I can create pictures under the same conditions with my Xperia T - but I don't get that fog-effect.

took a shot yesterday from that...."thing" that used to be a snowman. Can't see any fog there? (taken w/ z1c black)

Flat glass can't reflect light into the.camera lense. But just out of curiosity I tested your theory. Covered the back in a matt vinyl. Same effect

@GR36 as far as I remember my physics classes refelctions can occur between every material Change, eg led-glass->glasscover->air
So a reflection would be possible, see my example:
@toxic_garden
try to take a Picture of the sky at night. Picture should be black. But it is not.
Close Pictures are fine for me, too. But move away 1 or 2m. Please try again.

Tried various settings, all the same. I still think this might be resolved by new firmwares in the near future. If it would be some kind of hardware issue, wouldn't this also affect pictures taken from less than 3 meters distance like those?

Huh.. Seems that I was wrong. Took some automatic "sky at night" pictures - the pictures were blueish. Then I changed into Manual mode and got nice black pics. Seems the reflection is not really strong, but superior mode creates a superior reflection ._.

I don't expect full quality pictures at night, but you can definitely see that this is a hardware related problem (reflective back) - this is not what I expected from a 500€ phone. (I still like it, but I hate the fact that the camera fails so badly)

This is not the point. Even a weak LED flash must not (!!) mess up the pictures taken.

at least, Sony seems to be aware of the problem now. I'm curious how this will work out. Still thinking of a software related problem. (e.g. better controlling of the LED might help, like changing the time between shutter and light etc.)
http://talk.sonymobile.com/t5/Xperi...ison-shots/td-p/541415/highlight/false/page/3

Can confirm this issue on mine, though I think its impact is exaggerated. The only normal situation (i.e. not covering the flash with your finger) where you see the issue is on long range dark shots, on which you shouldn't really be using the flash anyway
Edit: took a few example shots.. (ignore the overall quality, didnt bother focusing properly)

And for completeness sake, flash covered with finger: https://dl.dropboxusercontent.com/u/6953585/DSC_0051.JPG (should stress that my finger is not visible over the lens in the viewfinder, the colour here is purely reflection)

Guess what seems to fix the problem....

Slight noise when moving S20 Ultra.

Anyone else hear a slight rattle when picking up or tilting phone? I have the T-mobile Ultra and I noticed this today as soon as I opened it. When I activate the camera and do the same gestures I do not hear the sound. Once I heard it I can't un hear it. I will try to record the sound in a bit.
Recorded it but can't post link.
linksharing.samsungcloudDOTcom/GWL84K4gvRrN

I've had what sounds like a peice rattling when shaking it. Not sure if it's the cameras or a loud accelerometer.

Too me it sounds like loose buttons. I can hear it when I shake mine too.

I think it could be the camera. When I turn it on and shake I don't hear it. I hope its "normal". I shook my old note 9 and note 10 plus and they don't make that sound.

It's the camera modules turn on the camera and shake it see if it disappears.

Wont it just be the camera shutters opening?

My device rattles weirdly when first vibrate hits, when you shake your phone it's normal to hear noise from camera because of camera OIS but that vibration sound drives me crazy ! i thought I had faulty device but many many users have that issue, my s10+ and note 8 had that sound too, check if you can and answer me dial star#0star# and tap vibration if you hear that strange rattle noice...

It shoud be the OIS of the camera. Same here, when you use your main camera, you cant hear anymore, but the selfie cam you can still here it.

There are decent sized cameras in these phones now with shutters, we dont shake digital cameras and we shouldn't be shaking mobile phones imo. Treat them with care, mechanical shutters are delicate things
Sent from my SM-G975F using Tapatalk

This is the physical stabilization, don´t panic

There are no physical shutters in smart phones. The camera module is quite durable, even the so-called periscope camera. It can take quite a bit of gs in shock as shown by drop tests that destroy the front and back glass, the camera still works flawlessly.
The noise/rattle you are hearing is from the module(s) that feature optical image stabilization (OIS). These have elements that can move freely when the camera app is not running. It is perfectly normal and part of the design and is not a defect.

Glad I'm not the only one with this problem... Although the sound drives me crazy! But I also don't remember it making that noise when I first opened the box... Might still try to contact Samsung support and see what they have to say... Have you had any luck with yours?

I think it is probably more audible on the ultra than the other S20 series devices because the stabilisation on the zoom has 2 separate pieces that are suspended by electromagnet coils - check teardowns, there is the 90 degree prism, and also some other optical 'barrel' in the centre that moves back and forth as part of the focusing mechanism. (basically lots of moving parts for a smartphone lens.. and the device cant be powering the magnets all the time as it would be major battery drain).

Starting to think none of the you guys hang out on the Samsung s20 Community Forum. Or you would know this is normal. It's been discussed in at least 10 different threads. Enjoy the Phone and stop freaking out over stupid ****! lol geeze.

its normal the one you are hearing is coming from Optical image stabilization sensor dont shake it otherwise you may break something on your camera.
