I've had some freezes with my phone and I'm wondering whether I should take it back to Harvey Norman to get a replacement or whether the issue is related to software itself and thus should I just 'hold out' till a fix is delivered.  I've pretty much stripped the phone down to the Windows Phone 8 bare installation and still I find that I get freezes just doing basic things - I scrolled through my music collection then suddenly it freezes up. The strange thing is though it isn't happening 4-5 times a day but once every 2-3 days which leads me to wonder whether the software is just buggy and thus if I do take it back I'll just get another phone with the same issue.

Any feedback would be much appreciated.
