Rattle around the camera area.

I've only had my Ace 2 for about a week now but I've noticed if you turn the phone over and tap around the camera area, their is a rattling noise heard.
Is this normal? What causes it?
Cheers

It's not a software issue mate. Literally hold the phone in your hand and tap with your finger around the camera lense and their is a sort of rattling noise.

I dont hear anything.

I can hear it if I tap quite hard just above the camera. Also the phone has to be in your hand and not on a hard surface.

i have it but under the flash

I have it under the flash to but not as much. Would be interested if anyone else has this to.

I think it's the back cover of our device. It's all about friction between plastic and camera.

So you have it aswell?

Yes, under the Led. But i'm sure it's the plastic, take a look under the case. There is quite big gap between led and camera, and this cause noise.

Do you get any rattle at all if you tap above the camera lense, just under the 3.5mm slot?

Hmm weird, not sure why mine does this then. It's literally just above the camera lense, tap it over and over with quiet a bit of pressure and it rattles.

Ok so I've looked around on lots of other websites and lots of different types of phone report this issue and apparently it's normal.
Your guys phone is probably rattling when you tap it near the camera but maybe you're just not noticing it like I do...

Ok I've discovered something else and I think this is to do with the camera.
Open the camera, set the auto focus, tap the back of the phone near the camera when the auto focus is locked and you'll hear it rattle even louder.
This must be something to do with the camera/auto focus and from looking at Google it appears to be normal, but can anyone else confirm this please?
Thanks

I think that it is Accelerometer sensor

Do you hear it to?

anyone else?

If it happens when the camra is focusing, I would expect it to be the noise a digital camera makes when it focusses. It happens when you tap the phone because the camera would need to focus again...
... I don't think the Ace II is for you. May I suggest a Nokia 1100?...

It also happens when the camera isn't on though.

Fingerprint scanner with camera?

I saw an app being developed 2 years ago but I guess they actually never finished it. If you're interested the app was called biolock by blueplanetapp. So is their any app that does this for android?

I tend to agree, only because of the fact that a camera needs light to function. Digital cameras are after all photodiodes. If your finger was on the lens, there wouldnt be any light with which to image your finger.
Now, assuming you were to unlock via this method by holding ur finger a few inches away from the lens, I still dont think it would work as it would likely lack the resolution/fine detail needed to function and actually be secure in any way.

Duo camera issues.

I keep getting a message about duo camera lenses being blocked. Does not happen in portrait mood but always in landscape mode it happens while I hold the phone by the very edges. I am inside my house could it be that there is not enough light?

Could there be dust or a fingerprint on one/both of the lenses?
Also if you're using a case, make sure that it isn't covering either lens as well.

No case and I don't see anything on the lens. I guess it's just mine. Contacted HTC and they said it's an app interfering with the camera because when they had me boot the phone into safe mode, the problem does not occur. I don't have anything downloaded that's camera related.

By any chance does that happen when you block the sensor next to the front camera?

Idk why would that matter taking a picture with the rear camera?

Update***
The issue has not been happening lately. I didn't change anything. Anyway I didn't really buy the phone for the camera.

If anyone can figure out what app may be interfering, I'd be curious to know as I'm getting this error also. I also don't have any camera apps.

I can cause the message to pop up in auto mode by getting the lens close enough to something where the top lens doesn't see the same thing as the main lens but I'm guessing you weren't very close to anything since you were in landscape mode.

This. I've noticed myself when taking a picture and something is closer to the left side in landscape mode.
The whole reason behind this camera structure is for depth. That is why 1 lens is slightly recessed to the other. Its provides better distinction making it similar to the human eye. Yes, one eye is slightly recessed to the other, allowing this to occur. We are smarter and faster at processing that information better than the phone can, so essentially, if something appears closer to the left lens, it will error out.
Fix, cover both lenses, move camera, uncover.

Duo Camera Blocked
I am also having this issue. My original M8 camera worked fine but I swapped it due to an unrelated issue. Now, whenever I load the camera app, it says "Duo Camera Blocked". Obviously there is nothing in the way and I have no third party camera apps installed. In fact I have the exact same setup as the previous phone which didn't have an issue.
I'm starting to think that this is a hardware issue and will need replacing. Is anyone else seeing this problem?

duo camera is blocked
First sorry for my bad english,
I got the same problem..When i open my camera app it says '' Duo camera is blocked blabalblaa '' even i ddnt cover the duo camera with my fingers..I sent it to Technical service to change with new one and im still waiting the results from service..And i think this problem will be a chronical problem like what happen to m7 ( pink camera ) last year..

This duo camera's on HTC One M8 GPe, right?

Yes my friend

Anyone help it ?

I just got my M8 today, played with it for a couple of hours before unlocking the bootloader. Restored titanium backup after unlocking, everything was fine until I opened the camera. I also keep getting the "duo camera blocked" warning, I tried taking pictures for an hour straight but the warning persists and I can't use U-focus or any other duo feature on every picture I take.
I'm on stock ROM and recovery and unrooted. Tried to restoring factory settings, no success. Just updated to the newest firmware (1.54.401.10) via OTA but still no working duo camera.
Should I sent it back for repairs (with relocked bootloader) or has someone found a solution for this problem?

Hey I started the thread, but I can not explain how my issue as just gone away. But I think I stated I don't use the camera that much but have recently been using it without issue. Strange. When in doubt I would just exchange if that's an option for you.

I know this is probably very obvious, but make sure your finger isn't covering the Duo camera at all. I've had that message a couple times and it was due to my finger blocking it. You won't see it on the screen.

I'm definitely not blocking the second camera. I tried taking pictures in portrait and landscape, inside and outside, with every possible grip, there is no dirt or dust on the lenses, it just doesn't work..
I just got on the phone with customer support, they advised me to sent it back for repairs.
After calling I just noticed something that might explain what's wrong with my phone. If I look very closely at the second camera lens, it seems like it's tilted sideways a couple degrees. I attached a photo taken through a mirror (I don't have another camera at the moment). Can someone confirm that it's not supposed to be this way?

Its hard to tell in the pic, but to me it looks like the Duo is aimed slightly up. Try taking the pic a bit farther back from the mirror and without the case. Also I've found it's very sensitive to fingerprints causing slightly blurry photos, and you have one on the main lens. See if you can get a slightly clearer one.

Here's a better picture, taken with another camera. I drew a red square to show how the lens appears to be tilted.
I'm sending the phone back for repairs tomorrow, I hope they don't make a big deal of the bootloader being re-locked.

Camera Problem

I have a problem with my back camera when using flash, it sometimes has a line on the left side of the screen and looks like the flash has only flashed on one part of the screen
Here's a picture. https://pbs.twimg.com/media/BxcEVZzCQAAI7Ny.jpg

Please try with Google Camera or another camera app to exclude an hardware issue.

My back camera not functioning.. Tried all camera app and kernel as well.. Is it due to hw faulty..? Currently only front facing working..

swapping camera sensor's

Iam looking at swapping my isocell camera sensor out to the sony camera sensor. I already took the phone apart and swapped the sensor out but it would not recognize it.
I wish I know alot more about hacking into the software of the phone but i do not can any body maybe make a flashable zip with the sony sensor software? I am willing to pay for your hardwork.

O_O Did you confirm with anyone before doing this, as in whether this is even possible? Sounds like a very dangerous and costly game you are playing.

Youll need to either go through the samsung hidden menu and update camera driver or maybe reflash full firmware with 4 part files

I thought this would be a straight swap. I intended to do the same before I installed my battery cover, but I didn't have the patience to buy/wait for the Sony camera.
