Did you remove the plastic film from the lens.

Duh thnx just seen this never thought of checking that

 

Check very closely because the film is sometimes really hard to see. I've handled close to twenty S4's and all were shipped with the film on them. It is not the same as on the S3 it is clear film to protect the lens during handling and shipping. Like the one on the S3 it actually has an opening in the center and allows you to take clear pictures at first but after time lint and what not gets trapped underneath causing spots just like you are describing. The lens is still fully sealed when it is removed as it is just a thin piece of film.

 

If you are sure that the film is not there I am stumped. The S4 camera is sealed really well and I cannot understand how debris can get underneath the lens cover unless it was not installed correctly in the first place. Perhaps a warranty replacement is your best recourse.

 

Are the spots large or small? Pixel sized or large blotches? Are they clearly defined or hazy?

It would help to post a sample. If you can't upload to here...upload to any number of locations and post a link. There are numerous ways to post photos on the Internet for free.

Did you try to tap one of the corners of the phone on a table to see if you can make the spots move around and dislodge themselves?

 

This is the lens film I was referring to:

It looks like it's definitely something with the hardware, I would take it in to your nearest carrier store and ask them about it, or email/chat with samsung.

 

Thank you AeolianReflex I never noticed that small circular donut shaped piece of film. Thanks for the video link!!!!!! Easliy removed and makes a WORLD of difference!

 

I have the same problem on my s4. Maybe I have even more of those black spots but they look identical to yours. Did you end up solving this problem? Did you take it in for repair under warranty?

 

Hello and welcome to Android Forums alexandret!

Does your question mean that the fix, described in the thread, has not worked for you?

 

If the fix you mean is removing the camera lens film cover, then no. I removed that film the day I got the phone. My problem is identical to the one from user rpgutsy.

I have used a blower, knocked on the lens, etc. They just don't leave.

 

If you have removed the plastic film, as per the video, and the camera lens is clean and dust free then I would suggest taking your phone to the nearest Samsung Service Point or your carrier and request a fix or replacement under warranty as it would seem that the problem is internal dust on the lens.

 

I ended up taking it in for service at a repair center. They replaced the camera module, under warranty. Now the problem is solved.

 

Thanks for the update. Glad you have got it sorted out alexandret

Although the phones are assembled under clean conditions, it only takes a few microscopic specks of dust under the lens, during assembly, to cause a problem.
