Looking at the body of one's spouse after their demise

Q: My grandmother passed away a few days ago and after she passed, someone said that my grandfather is now a non-mahram for my grandmother and that he cannot look or touch her dead body. Is this correct? Because I have never heard this before that a wife and husband become non-mahrams after one of them dies. Also, can a husband give ghusal to his wife after she dies? Can a wife give ghusal to her husband after he dies?

Video calling

Q: My uncle passed away yesterday. His daughter and uncles younger brother stay out of the country and for them it was not possible to reach before the funeral hence for the last dedaar ( viewing the face) video calling was made just to show the face of my uncle to his daughter and brother. No photographs/ video was saved of the janaza only video calling was done for 3-5 minutes. The same was also confirmed with the maulana who was present. It was just use of technology for showing the face of the expired person to his loved ones who could not reach on time. I would like to know if this act was permissible or was anything wrong done?
