Hi you all

I just came back from a trip to Senega and was watching the 2 videos I made there.
I noticed straight away that there is a small unclear spot on the film. I have checked the for visible dirt but can see any at all. So my conclusion is that is probably on the sensor itself. Does anyone have any idea of what to do about this??
I bought the Spark less than 2 month ago


thanks for any help

I don’t know Senega. How was the humidity there?
If it was moisture, it may be gone now.

Clean your lens regardless of whether you can see the spot.  I doubt one's ability to see a spot that causes "a small unclear spot" on such a tiny camera.  I had to clean my lens for a unclear grease like spot that I couldn't see externally.  

Hi, there. Please clean your sensor first. If your drone has the problem again, please provide a picture or a video about the situation. Thanks for your support.

Thanks for all of your responses.

First of all just to correct a typo it was Senegal I was visiting.
I have cleaned the lense, but the spot is still there.
As you can see on the photos the spot moves a bit when the camera uses the stabilization, when i shake the camera.
I have been trying to upload a video of it, but haven't been able to do it yet, tried both computer and iphone browser.

Here is a link for a video of it

Feel free to comment anytime, now that the video of the problem is here

To me it seems like dirt on the sensor itself. In case it was anything on the lens, it would be much more blurred – edges here are way too good defined.
As electronic stabilization kicks in, it seems to be moving – due using using of different sensor crop area.
You won't be able to clear it on your own... that's possible without risking your warranty only on cameras with interchangeable lens.

Hi Mara, Yes thats also what I concluded. Now the only thing is how DJI are going to help me with this, as this happened only 2 month after buying if. And as far as I can see its impossible for dirt to get inside the sensor box, as it looks VERY sealed.

It's sealed and it shouldn't happen, but Spark's sensor is fairly small, so your problem can be caused by just very very little dirt. Anyway I would contact DJI.

So the end of it all is, that i send it in for repair and if was fixed by DJI without any cost for me. VERY good service.
