I had the phone about a year and had at the beginning exactly the same problem had with the memory card as described in the recession of "atomschubbser". After one sending in, we went though. Until yesterday. Since it is assumed me for no reason and can no longer since power. The Sony Ericsson logo is more, then the display will flicker briefly and that's it. I am neither dropped nor anything else. Had there only day every day in my pocket (in a mobile phone case) where it is obvious to the mechanical stress was not held. The shaky impression can thus be transferred to the overall processing. Those who want a rugged phone is wrongly advised with the W715.
