While on my deliveries, I was using my gs3's navigation and at one point put it to charge. When I did it suddenly turned off and I had to pull the battery. After unplugging it for another delivery I put it back to charge and it shut off again. This time it wont turn back on even if I leave the battery out for a long time. If I put it to charge for a couple of mins the lower part of the phone feels pretty hot. I heard of some GS3's getting this thing called sudden death syndrome but I wonder if MPCS gs3 is also affected? I had one of the custom roms installed but I think this is a hardware issue.
. The JB update fixed all that...supposedly. Take it to a Metro corporate store & they are supposed to replace it. At least that is what I have read.
. End Of the Story... But wait... at the end it wasn't the cellphone the problem, My battery were gone, because they tried to turn it on the "re manufactured" S3 with my old battery and it didn't turn on... so the guy decide to give me both things new, Device and Battery, so after they change the battery my S3 turn on again. they charge me around $50 for both things. Device replacement $15 and battery $35. I hope you have the same lucky like I had Man.
