Hey everyone,

I'm using a Samsung Galaxy S21 FE and ever since the latest software update, my phone has been having major network issues that are making it almost unusable for calls.

My phone randomly loses network in areas where it used to be perfectly fine before the update and slowly it is loosing network in areas it used to work after the update too.

When people try to call me, they say it keeps ringing on their end even though I already answered, and my voice doesn't go through at all.

Even when I can make or receive calls, the voice either breaks up or doesn't transmit at all.

The Flight Mode toggle gets stuck - I try to turn it on or off and it just freezes. I have to manually go into Settings > Connections to force the change.

It's clear that this is a firmware/modem bug introduced with the last update. I love Samsung (this is why I got the S21 FE in the first place), but this is seriously killing the user experience.

Is anyone else facing similar issues on the S21 FE after the update?

If yes, have you found any permanent fix or should I just wait for the next patch

Thanks in advance!

I AM Facing About 1 Years.
