I bought this phone 2 days ago and it has since had a regular problem with restarting. When I put the phone on standby, a minute or two later it will restart and I will see the windows logo and Nokia text. This happens constantly whenever I put it on standby. What must I do? Is this a known problem? Was very skeptical when buying a windows phone, especially by Nokia!! Its a nice phone without all these issues. Really disappointed right now and would not recommend this phone to anyone.
