My dad has one, with MTN, and if you mean "restart issue" the issue where the phone randomly shuts down, then yes he does.
My dad got the phone about 2 months ago and it did not initially do that.
Recently (about 2 week ago) he setup a Wifi ADSL router at home, and ever since then he also got the random shutdowns. Looks like it is because of Wifi. The problem appears to be that sometimes if your phone goes to sleep while connected to your wifi it will turn off completely.
Suggestions are to not leave your Wifi on, only use it when needed, and turn it off when done.
