hi i have just purchased a new iphone 8plus and when i’m trying to record a slow motion video in my room it starts flickering, i even tried changing the frame rate to 240fps 1080p but it’s still flickering i’m currently running on ios 11 please suggest a proper resolution as this is a very major and genuine issue and a big disgrace to the phone standard itself
I am not an expert, but what I have the same issue, and I think I understand it. If you live in the United States the AC current coming out of your wall oscillates at 60Hz. This means every second your electricity is going back ad forth 60 times every second. This causes your light to flicker on and off 60 times every second. Your eye, and normal cameras, do not see this because it is to quick to notice. But, a camera that is filming at 240 frames per second is taking a picture more frequently than the light is flickering on and off. So, you see the light flicker in your video. To prevent this, you have to use a light source that uses DC current, such as a flashlight or an LED.
To better see this effect, try recording a computer screen in slow motion where you can see the reflection of a regular light on the screen. You will see that the computer screen does not flicker because it has DC power. However, the reflection of the normal light will flicker.
I am not 100% sure that this is fully correct, but it is the best explanation I can think of.

Hello,
The same is happening to me and it seems this issue is not new because I saw some posts reporting the same back in 2017.
I am also an owner of an iPhone 8 Plus and for a long time I didn’t use the slow motion mode but today using indoors it happened the flickering. I read in other posts the the fluorescent light could cause that, but it seems it’s not only under this kind of light. I’m going to test further tomorrow during the day, but I’m guessing you have an issue that must forward to your technical team!
I can always record a video and send you but I’m pretty sure I’m not the only one having this and this might be happening to all iPhone 8 Plus.
Before you ask, and because it’s proceeding, I have the last OS installed 12.1, and all my apps are updated. Also I read your suggestion and yes, I have my camera cleaned and no covers, etc, etc.
Can you please check?
Thank you in advance
