Bought one 18/8/2014 mobile when flat so I charge it about 50% tryed turning it on heaps of times rrrrrr still not turning on I'm not happy bought it from JB HI FI going in tomorrow to see what's going on .
There's something wrong...could be battery trouble even if new. With new devices, the battery already has some charge out of the box. You've done the right thing to return it. Tell us how you get on.
