Dead pixel in any video or camera mode

I obviously cannot take a screen shot of this but just now I was playing with the slow mo feature and I clearly see what appears to be a dead pixel. Now, it cannot be because a pixel because on the retina display is not easily discernible but it looks just like it.

It only happens in the slow mo function and it disappears in photo or rearguard video. Even the video taken shows it. Change in light make no difference. Any thoughts?

Sounds like a bad camera sensor. Try cleaning any spots or lint off the camera. If that doesn't fix it, you'll likely need to have the phone replaced.
 
I suspect you are right and it relates to the sensor on the camera. Oddly, as I stated in my first post, it only occurs in slow motions view as well as the clips that are recorded on it. It does not show up on anything else, including video and photos.
 
I'm also having the same issue. iPhone 6+. Not sure if it will show up in a screenshot, but here is a screenshot anyways:

Call Apple. When I called the senior advisor mentioned to me that they had not seen this in any of their csses. I even emailed him a sample video, which we acknowledged showed even exactly what I was talking about. He told me to hold onto the phone for a little while longer since it may be software related.

I restored the phone and it still did it. I believe it is hardware related.
 
Same here :/ Perfect iPhone 6, besides the 3 annoying dead pixels which are visible in slo-mo only :( I'm scared of exchanging my iPhone and getting a worse one.. But I don't want to have a defect camera-sensor with a brand new 800€ device!

hm... I don't agree with that. Slow motion takes 720p videos. That being said, you see less pixels. The pixel density is not as big as taking 1080p videos or photos with 8 megapixel.

Not true. In slow-motion mode it samples 240 times per second, resulting in a fairly short exposure. In regular camera mode it only does so 30 times per second so the exposure time can be 8 times as long. It just means that there's a few photo sites in there that are defective such that the defect shows up when exposure times are low but not with longer exposures.

In that case you'd likely also see it in well-lit conditions.

Thanks for your post. I am trying to wrap my head around this. So, in slow motion I see a cluster of pixels that are sparkling in a way. They show up on the recorded video as well. However, I have reproduced the same actions in various lighting conditions and I only see this occur in slow motion. I do not see it in regular video.

I still think it is hardware but I suppose I am holding onto hope that it is a software related issue.

However, as I stated earlier, I did go ahead and restore my phone and start it as a new device and it still did the same exact thing in the same exact spot.

I'm referring to the post above mine that mentions dead pixels. If it was a dead pixel would you not see it all the time? I just tested mine for dead pixels and have none. I do have one bright pixel when in slo mo mode though

I have the same 'bright pixel' in slow mo. I am glad that I am not the only one experiencing this. It seems to be related to the camera sensor, because, as I stated earlier, dead pixels are not really discernible to the naked eye.

Well, there is nothing to be glad about.. My friend also got the iPhone 6, I've made a test with his iPhone and he doesn't have these bright pixels in slow-mo. I do.. And it pisses me of!

Well, I understand why you would be pissed. When I said I was "glad" I simply meant it in the sense that I am not the only one. Surely that is not the outcome we all want.

I still cannot figure out why it is only occurring in slow motion and not in the regular video. I saw that someone above posted saying that slow motion is in 720p while the regular video is 1080p, which affects one being able to see the sensor issues.

so what did you do, i have this on mine and this is not ok. Have a genius app later today. Did you get it swapped?

Also, since you paid full retail like i did, will you let them give you a "refurbished/replaecment white box unit? or will you demand a brand new sealed in the box retail unit?
