Hey, is anyone having an issue with their SIM card not working after updating to One UI 7? Before the update, my phone model was SM-G990U1, but after the update, it shows as SM-G990U1/DS.
Now I get the message: "Emergency calls only. Invalid card." — even when no SIM is inserted.
In the settings, there's now a SIM Manager that shows a SIM 2 (Unknown), which shouldn’t be there, as my phone is a single SIM model. It seems like the update installed software intended for the dual SIM version of the phone.
