Samsung Flipshot SCHU900 Calendar Problem

I have a problem that Samsung said they never heard of with the calendar on my phone. It deletes appointments on me and then it will limit how many appointments I can enter. The alert will go off at odd times and you will not be able to access the calendar. I did a google search on this problem and it seems many others are having the same problem.

If many others are having problem, then it's definitely a Samsung phone issue and they must be lying to do if they don't admit there is a problem. Who knows, they must be secretly working on the fix but don't want to admit there is a problem until they have a software upgrade.
