Disappearing icons

[Jovis]

Hi

Since update when I open my S21 ultra the icons come on then dissappear for a second then come back?

Also while on WhatsApp I was looking for the app icon and the whole page of icons had gone? I have three pages with icons, first and 3rd page were there! As usual the page of icons I needed was gone!

When I locked and unlocked the phone it was back. 

Ps phone seems a lot fast at loading now 🙂

@Jovis: This may have been a temporary issue, however I recommend pressing the Volume Down and Side Keys together for around 10 seconds until the S21 Ultra restarts, as this will refresh the software and address any issues that may have been a contributing factor. Don't worry, this won't affect your personal data or settings.

Hi

Have reset cache etc! Still happening.
Not a great problem when they flash off only for less than a second.
But a full page of icons not so good?
Had to lock and unlock phone, they came back. But you do panic for a second 🙂
