My phone recently had a coniption. Everything worked fine except that I couldn't make or receive phone calls. Messages went through fine, but no calls. After some research, I found that the only to fix it would be to back up my phone to Samsung Kies and reset the phone to factory setting. This I did and it went very smoothly. My issue was resolved and I then used Samsung Kies to put everything back on my phone. However, my S Calendar has decided not to do so. Now it shows nothing. When I go to create a new event and click 'save' it doesn't appear either. I've gone to my Google calendar and that shows nothing either. How can I fix this?
