no network issue and no sim. emergency calls only

[Luvharry]

Since the last two update my Samsung Z fold is losing network connection and says no network and after sometime no sim. i got a new sim from the operator thinking this is because of worn out sim. but same issue. I changed network provider and same issue. 

It seems the last two updates had really affected the connection to network. I restart phone or remove sim and re insert it and I will get network for a few seconds and tha no network error and later no sim. 

this is a serious critical issue please help.

This should be a firmware issue since the problem started after an update.
