iPhone 12/ 12 Pro Max: laggy display while recording timelapse video on front camera

[Eisselmann]

Hey guys.

I have found a strange behavior of my iPhone 12 Pro Max and was able to reproduce it on an iPhone 12 and another 12 Pro Max.

Situation:
iOS 14.2.1 and 14.3 running on the iPhone 12/ 12 Pro Max.
Open the camera app, switch to your front camera and select timelapse.
When you start recording a timelapse video while holding the device in your hand everything is fine.
But position your device on a table so that your whole body is visible on screen:
The displayed image from the front camera becomes laggy as hell with like 1 or 2 fps.
The video recorded however is fine.



Apple support on Twttr says it‘s supposed to be normal behavior but it is clearly not since I wasn‘t able to reproduce that malfunction on an iPhone 11 Pro Max or 11.

I wonder if you can recreate this problem.

Can you?

Hello, I'm in the situation you're in. Have you found a solution? 😔

Nope, unfortunately still the same even after 14.3 update. :/

Now I also have a laggy display when recording timelapse videos on the main cameras. Meeeeeh...

I found a fix in the Apple forums:

You gotta activate the autofocus lock before recording the timelapse video.

So it‘s a bug.
The autofocus apparently always tries to focus all the time, so slowing the device down...
