I would like to have a highlight back recording
The attached screenshot is a highlight back recording supported by Lenovo's gaming smartphone Legion Legion Duel.
On Lenovo Legion Duel, It can back-record highlights situation at up to 1080p 30fs, and store up to 30 seconds.
I wish there were similar features in Oculus Quest 2. You can't show it to other people unless you're recording, even if you've an interesting situation comes out.
