Does anyone exactly know the vibration pattern for shutting down the Xperia 10 III?

Hi!

So I used to do a full image backup using recovery mode before every new update of SailfishOS. If you want to get back out of recovery mode and flashing, you need to hold some buttons and then wait for a vibration pattern - one time long and then three times short - and only after that you can release the buttons.

My problem: after a display change, my Xperia 10 III doesn’t vibrate anymore, so I cannot know when this vibration pattern is done (and therefore when to release the buttons). That’s why I don’t dare to try to backup my phone anymore.

My question: does someone by coincidence know, how long it takes from starting to press the buttons until I can release them? By knowing this delay, I could start to do backups again without worrying that I will never get out of the recovery mode again
