Note20 Ultra 5G Groups Texts Messaging issues after recent update

im actually surprised you get signal being in the second to last floor of the tallest building in your area..usually the taller the building the less signal you would get since they point the antennas towards the ground and not up into the air. my mom has been running into the same type of issues with her i believe S21..doesnt receive many of the incoming calls...texts are pretty hit and miss..Samsung junked up something in their last couple updates they have pushed out.
