Why Does the Screen Freeze when Using the Telephoto Camera for the First Time?

 

Situation: The screen hangs/ freezes and does not focus for 3 seconds when using the telephoto camera for the first time.

Applicable to: Reno 10x Zoom

This is because the system updates the Optical Image Stabilizer (OIS) firmware during the first time of using the telephoto camera (5x zoom and above). There won't be any issue once updated.
