Hi,

Since a week ago (2nd of March ?) all new SMS I receive are showed as "Unknown" instead of the number or name (if in the contact list) on the car display. And if I try to open them in the car MMI I only get an error message "Format not supported". For every new SMS I receive, a new "Unknown" line appears.

It's only the incoming map that doesn't show the SMS correct, other maps as Sent, Trash etc looks and behaves ok. Also the list of contacts, call and receive phonecalls and dialling with voice control works ok. And all SMS looks normal on the phone.

Telephone is a Samsung A33, Android version 14. No system updates or re-configurations at the time when this issue started.

Another attached phone (Samsung A50) works ok.

Tried to restart the phone - no difference. Removed it from the car Bluetooth list and re-installed it - no difference. (Cannot test the phone in an other similar car right now my wifes A3 is too old and doesn't support manageing SMS on Bluetooth)

Any ideas ?

Are they SMS or RCS messages?

MIxed.
I can see older RCS and SMS, but since a week ago no identity at all is showed on the incoming regardless of RCS or SMS.

Received two with SMS format only a few hours ago, and a marking that "new message received" showed up. But still the same - two new rows but with text "Unknown" and not possible to open.
