I updated to Nokia Suite 3.7.22 and since then I have had problems with sms synching properly. One of the biggest problems is that although I read messages on the PC, they are not showing as 'Read' on the phone. This means if I have lots of messages, I have to mark them all as read on the phone.
Is this a problem that Nokia are working on? I have a C3-01
Try repairing Nokia Suite. Go to Control Panel > Add/Remove Programs or Program and features and then look for the following components:
1) Nokia PC Connectivity Solution > right click the mouse > select change > repair
2) Nokia Connectivity Cable Driver > right click the mouse > select change > repair
3) Nokia Suite > right click the mouse > select change > repair
After repairing all components reboot your pc, then double check if it resolve your concern.
Hope this will help you my friend
