Good day one and all.
My phone was working fine this am and now [830pm] it won't switch on from sleep mode. The battery is at 95%. The fixes I have tried are 1) holding power/volume down/home key down for 45 secs; 2) taking the battery out, replacing it and trying (1) again; 3) holding the power key down and plugging into my desktop with USB cord. Nada. Zilch. Any ideas how to get this functioning again or why this even happened.
