I have wifi and network connection issues with samsung Galaxy S21 ultra 5g.
Tried all suggested actions on samsung groups
May be some hardware issue.
Kindly help me to resolve it.
Try rebooting your phone. if that doesn't fix it, plug it into your computer ad shut it down, then hold the Power and Volume Up (+) keys together until you are greeted with a text menu. navigate down to Rapair Apps and it will fix anything broken in the update.
