Video call blurred on tablett

Hi,

Yesterday i noticed my friends camera is blurred / all squares.
sound is ok.
We did not check after latest update ( received today)
They are using tablett

Do they need to change settings in media? Resolution ? Frame rates?

Thank you

Maybe you need to change the video codec and/or it’s one of these issues:

The artifacts are precies the things i get, but i do not see any solution…and topics are already old.
