I have an s20FE 5G with the carrier being spectrum and I had updated my phone last night with th One UI 3.0 update. It worked completly fine with wifi and I made a call later after leaving the house. I was trying to pull up the news when I realised I had no data. I restarted my phone multiple times and pulled out and cleaned up the sim card. Is anyone else expieriencing this problem and if so has anyone fixed it?
Power off the phone, press and hold volume up and power at the same time till you see the green android guy, when the menu shows, use volume down to go to wipe cache partition and use power to select. It wil take a little time, but you won't lose any data or apps.
firmware search and find andriod 10
example mine was sm-g986u youll see it
the instructions are also on the site. very simple . backup before hard reset
