Does anyone else have a tremendous amount of issues with the Lumia 521? Some of these problems are:

Turning completely off at the slightest bump not sending specific messages such as "Me too." when on WiFi

The screen turning off and requiring the force of taking the back off (or touching it) to shut it off completely and them turn back on

Not being able to send or receive pictures. Pictures send if it's within the first few texts I've shared with a contact, but other than that, it just says that it's downloading media, but it doesn't seem to be doing much of anything.

Not being able to send or receive group messages, experiencing the same problem as with sending and receiving pictures.
