2 problems...repetitive notification sounds & TouchWiz stopping.

[Katrina Baker]

I got the Tab Pro 12.2 for Christmas...and the first problem is that from the moment that I set it up, I keep receiving consist repetitive notification sounds. Sometimes there is a notification, & sometimes there isn't. It's VERY annoying! The second one is the same problem that I keep having on my S4, "TouchWiz has stopped working". I have talked to Samsung about this and they basically told me to soft and hard reset, & when I informed them that I had...I was told to send it in for repair. I haven't done this yet, I can't be without my phone for 2 weeks & was hoping it would stop. But now it's happening on my NEW 12.2, needless to say, I'm not happy...but I was wondering if anyone else is having these problems before I take it back to the store? If so, any solutions? Thanks!
