Mark on Camera Lens - Bubble? - Xiaomi Mi MIX Questions & Answers

Hi All,
I've got an odd mark on the rear camera lens, i'm pretty sure it's not always been there, and from the looks of it is on the surface but it will not rub off. Tried Glass cleaner wipes, micro fibre cloth etc. It almost look like when you get an air bubble trapped under a screen protector. I know it's only tiny, but i know it's there and it's really bugging me.. any suggestions on what it may be, how to get rid of it?
Cheers
Paul

Some manufacturers do put a small clear plastic protector over lenses just like the one on the touchscreen when you get the phone.
Check it's not got one as you may simply need to remove it.

Thanks Pat, It was my initial thought, it really looks like an air bubble. But I've tried peeling at the edges of it with my nail but can't sense if its got plastic on it or not.
I'm beginning to think this is something on the inside of the glass.

Ah well, let's see if anyone else has similar, I assume it doesn't affect anything, just asthetic, I haven't a comparison myself as I've yet to get my hands on a handset.

The bigger question is - does it affect picture quality?
The sensor doesn't cover the entire glass face so it might not. However, it may cause glare/reflection side effects if the sun shines on the bubble.

I have to agree with Pat, I compared your picture to mine and unless it's just the picture it sure looks like there is a film of some kind on it. Try a good piece of tape towards the edge of the ring and peel it up, you never know.

Big difference: With and without backcover!

Hey people, look at these 2 pictures, that I just have taken:
With the backcover on:

And without:
http://www.4shared.com/file/53179169/2c2a3a6/Uden_cover.html
As you can see, there is a big difference. Hmm, why haven't HTC done something to this problem?
Are you sure you were at the same distance?
And what about the focus point? It seems a bit different between the 2 pics.....

Yes I'm very sure about that. I have tried with more pictures.
did you stick a 'lense protector' on the cover's lense screen? like if you stuck on a full body protector like invisibleSHIELD there'll be a piece for the lense cover too.
Or, did you forget to peel off the original one?

Haha, no i'm not that stupid Nothing "protection" is on.
the "lens" that is part of the back cover is obviously not optically neutral. Pretty lame if you ask me.

Without the back cover, the Diamond takes decent pictures, still slow on focusing and shutter release(you should see the Samsung F480, this little fellow shoots pictures almost like a normal digital cam) but pretty good for a 3.2 MP cam.
WITH back cover however, the pictures look like crap to me. Sometimes it looks like if the pictures have been taken through light fog and I can clean the lens cover as much as I want(not easy, tiny little bastard), after some time, the lens gets dirty/whatever again. Horrible, HTC definetely needs to find a better solution.

well ideally you should or you should remember not to put you fingers on the lens (not an easy task given the camera position i know) but lets be fair here, i mean its not as if you would take your stand alone digital camera, smear you greasy hands over the lens all day (+ let dust collect on it) and then expect it to take perfect pics...
be practical, if you remove the case screen for long you are gonna end up with scratches on the actual camera lens! and that's not easily replaceable now is it (not like the back cover...) lol

What we need is a back cover with a piece of glass in place of the piece of plastic which covers the lense.
This seems like the only solution to me.
Its because the plastic isnt very durable, it does mist up the photos. If you look on coolsmartphone.com ive also took some pictures and they looked alot better without the back plastic cover on.
I just hope someone somewhere is reading this as i would pay for a back cover with glass instead of plastic lense cover.
The pictures are alot sharper and arent misty without the cover on.

Your right!
white balance
Granted the backcover lens protector doesn't do justice to this phone. Adjusting the white balance does for improvement (say the lighhtbulb mode) I find. Again the camera does let this phone down, compared to others of similar spec. Can a software tweak solve the lag in motion when shooting in video mode at all? Is it as a 'simple' case as that I wonder!?
I just did some test shots with my xda diamond from germany and I honestly cant see a difference. can you tell which one is taken with the cover off?

Camera window fogging up? Polish it.

I don't often use the camera in my Tilt, that is to say I never use it on purpose. If I need a camera on the spot, I'll use it. It's better than nothing sometimes.
I hadn't used it in a while and this weekend I needed to grab a photo of something and I noticed that the window on the battery cover was very strange looking, almost a fractal pattern of scratches or etches on it. Very light, but making it very foggy. Unfortunately I didn't notice until later, and my shots were horrible. After I noticed the fogginess, I took a few test shots with and without the cover, and without the cover the shots looked as 'good' as they ever do.
So I got out my Novus plastic polish that I use to polish up light scratches out of gadgets (similar to Applesauce and other products) and polished the window for a few minutes and all of the weird foggy layer went away. It took a few times, so it wasn't simply dirty, etc. Now I have a 'ring' of this weird looking fogginess around the edges of the lens but that doesn't affect the camera. So I took a few more test shots and the different between with the battery cover and without are back to negligible.
Just thought I'd mention it for folks who are taking off the battery cover to take photos or thinking about removing the 'lens' in the battery cover. If you have something to polish plastic and your lens looks foggy, give this a try.
I might try to take a picture of it sometime, but not sure I'll be able to really capture it well.
I used brasso brass polish for the same result, works well with a bit of elbow grease. As for the "halo" left around the edges I took a wooden toothpick and covered the end with a bit of paper towel and got rid of the "halo" by polishing in circles against the edge to remove that halo. Now my cover is like new!!!

yes, it looks like a "rainbow" on the surface almost like if you were to blow a bubble and catch it and look at it you can see a rainbow of colors in the bubble.
After I polished it it was clear, the before and after effects were enough for me to see.
must have been somthing on our fingers that got on the cover or something like that.

I'm beginning to think you're right, it was a suspicion of mine to start with as the only thing that could have really made a lot of contact with it is my fingers. And sure enough after a week or so, the window is starting to get funny looking again. I touch it all the time by accident, it's just in a perfect spot to get fingers on it.

Just in case people aren't aware, the lens cover is not plastic but really thin coated glass. The coating thats been applied to it clearly isn't heavy duty enough for the type of ordinary use the device gets as mine also developed this problem, even though I'm very careful with how I treat it. I too used brasso to polish the coating off and then cleaned it with my Klearscreen and microfibre cloth and all is now well. I thought the blurry photos I was getting were because I wasn't holding the device still enough but it turned out to be Chromatic Aberation (click the link for an excellent Wikipedia description).
thanks for the advice, now my pics won't look like they've been altered by some cheap gaussian blur effects,

Fingerprints, Dirt, enc

Hello folks,
As most of you reading I am a happy Topaz user,
But I find it sad, that I almost do not dare to use the device without stylus
Whenever I touch the phone, it leaves a dirty mark...
And I cannot live with that, So I always want to clean it afterwards
I mean... even with a screen protector installed, it gets dirty too quick,
And I recon I cannot walk around with a bunch of cleaning tools either
So, what's your opinion on this? or do you have a good solution?
Do you care that the screen is dirty, or not? please tell me
Thanks already
- Jeutie
is ok , you can always change screen protector .

I use an antiglare screen protector I got from Brando (http://shop.brando.com.hk/bw-pda-screen-protector-htc-touch-diamond-2-_p03225c1035d039.html). You lose something in brightness but it is very impervious to dirt and fingerprints.
There is also an hot debate on matte finishing battery cover. I simply painted the original cover using matte spray acrylic paint (http://forum.xda-developers.com/showpost.php?p=3950791&postcount=67) Of course you need a bit of manual dexterity and a brave heart...
I just leave it dirty
I thought about another screen protector aswell... but I think I'll fail again xD
(screen protector was dusty already when I putted it on, But I'll try again.)
Thanks for the information
But Would you recommend the normal screen protector or the Ultra Clear one?
Hi
Yep feel the same, hated touching it when I first got it as any touch leaves a fingerprint, if you try and wipe it away you make it worse. The aluminium surround really shows up finger prints and then smudges and so does the screen even with screen protector on. Even ear prints are clearly visible!
This isn't unique to the Topaz though, the state I've seen some iPhones in
So I just live with the fact it only looks shiny and new after a quick clean with some cleaner and a microfibre cloth, for just a short period of time.
It would help if the back was matt black or rubberised, but it isn't. I really don't understand the people that design these things as surely they must put them through some form of user testing, and I can't believe out of an even tiny group of testers the comment 'finger print magnet' didn't arise.
Regards
Phil
I do have the matt finish ;-) bought it way overpriced on ebay...
But the screen protector didn't help so I was looking for something better
and indeed, the aluminium is even worse xD

The Ultra Clear looks and feels as the original screen and as other screen protectors, that is glass like. Therefore, dirt and fingerprints remain very visible.
On the other hand the antiglare has a kind of very small granularity over it. Dirt and fingerprints do not stick to it and fingers, nails and stylus glide very nicely over it. On the other hand, it is not completely transparent, expecially under direct sunlight.
But so, for the fingerprint issue, the normal one should be better, then the ultra clear one, Thanks
I'll order one on Monday, And I'll get someone less clumsy to put it on ^^

That's a PERFECT DEFINITION!

The painting is quite resistant but of course scratches accumulate as they did on the shiny original case (but they are a bit less visible). The good news is that on too many scratches paint can be applied again...
You're right! If it's been successfully done once, why not repeat it if needed..
Hoping that none of us will ever need it,http://www.expansys.com/d.aspx?i=179389 is one of the most expensive pieces of plastic on earth

That "thing" with two holes is also on sale at HTC's:http://www.htcaccessorystore.com/uk/p_htc_item.aspx?i=179389 as "original" cover for D2Very affordable as usual.. I get mad if I think it's about 10% of the phone's price. My ideal back cover would be mat gummy black, just like the Kaiser (a.k.a TytnII).. hope someone is going to think about it!
Aright... I have applied the screen protector...
That's great! no more fingerprints on the screen
Together with the backcover and installation of some cabs... my device is totally like I want it
Thanks folks!

How's your camera lense wearing?

I've recently noticed that my photo's are starting to look like crap compared to what they used to look like 10 months ago.
The only thing I can think of if the camera lens, which seems to have scratched and worn pretty badly.
Unfortunately the lens is built in, not the in back cover, so it's not really possible to replace.
Any ideas?
What does everyone else's lens look like?
Maybe get some kind of cleaner like alcohol wipe or something to clean it? I'm not sure, just throwing an idea. Mine doesn't look too bad.
I had the same problem. Not the lens but cover that protect lens was scratched. Pictures became a large blur. I changed it via warranty. If you don't have warranty you could try this.
http://www.ebay.com/itm/Replacement...131?pt=LH_DefaultDomain_0&hash=item43b1e7b893
Im new on this forum. My camera's lens is good, two weeks after i buyed the phone, it started to scrach all the brushed metal borders. I have attached a small piece of transparent scotch tape with a hole in the center that covers all kinds of scratches. My lens works very well taking advantage of 8 megapixels with no blurring or difficulty when trying to focus on something. If your lens is damaged, do not try to put alcohol or any abrasive liquid. It can give you problems on your device. The best solution is to get a new replacement lens (I recommend genuine parts) and keep the plastic wrap or, in case of their absence, a piece of scotch tape.
Sorry my bad language. Personally I do not like google translate that translates very badly. Heh, I'm using all the little I know of English..

can I fix these scratches?

Unfortunately I got drunk the other day and the next morning I noticed a couple silver dots / a couple small nicks in the circled area below. I can feel them a bit with my finger nail. I tried to cover it up using a permanent marker but it looks like crap. Any way to fix it?
Here's what it pretty much looks like up close.

tape out both sides of the led light/lens and finger print reader as to only have the small 'bridge' between the two sections where your scratches are nit taped. tape off also bottom and top where the camera section meets the body of the phone. make nice and straight tape lines. then paint and varnish the exposed section . it will be barely visible if you do a good tape job. paint black wait for it to be dry enought then , varnish and remove tape after a few minutes when the varnish is still a bit soft. then for the love of god get a case.

I'll give it a try. And I've had a unicorn beetle case on it since day 1. I also kept on the back protector that it comes with, put on a screen protector, and even put narrow strips of clear packing tape on the right left and top bezel/frame of the phone and then put it into the case. The camera/finger print area is the only unprotected area on my phone. I actually just now put a piece of scotch tape over the fingerprint reader to protect it from scratches and it still works perfectly.
must have been real unlucky to had it dinged just at the wrong place.
That's what happens when you get arrested for public intox and cops confiscate your phone and put it in a bag with your keys.
So should I paint the whole "bridge" or just the two nicks?

maybe the whole thing as it might be less apparent and more cimetric. you could also paint the whole thin bezel to. might protect against future alcohol related endeavours.
I might paint the whole thing. Could I actually make it look as good as it originally is? What do you think about taping it off and spray painting? Idk how to tape off the curved edges of the camera/finger print reader.

spray paint on such a small surface... i dont know. put at least 3 coats. each coat must be thin and uniform. spray at a far distance.
painting on smooth surfaces usualy requires an enameled paint. U need a paint that will resist chipping and that will cure hard.
https://plaidonline.com/brands/folkart/enamels
as for your taping skills then stick to first picture to keep things simple and straight lined.
you could also use a wide tape and cut out the sections with a sharp razor that you need to paint.
when using multiple coats you need to wait a bit between each so it dries enough. keep in mind you still need to have the total coats to be flexible enough so when you remove tape that it will be removed easily and not chip the section you just painted. maybe practice on a piece of glass before.
anyways just be sure surface is grease free before painting.
