What have you done with this latest update,god its rubbish,i want to go back,but i cant see how you can,gps is miles out now,nothing has improved....Help.
Can you try a soft reboot by turning the phone Off and On.
The update may have nothing to do with your current situation.
As a process of elimination can you try your sim card in another phone.
Current Phone > Samsung Z Fold³ 5G.
