my galaxy s3 this morning unable to power on at all..

Guess the motherboard is fried. Didn't charge it and left it on table, this morning just hang with notification light only. So, i unpplug battery and put back and no sign of life. Send back to warranty. Just around 6mths only. WTF!

Hi guys...I'm new here but I've been using S3 almost 4 months..

I'm having dis trouble but I'm not sure whether its because of of my phone or because of telco provider..

My problem is I can't make/recieves calls in GSM/WCDMA Auto mode. If I'm lucky enough, my calls got thru for only a few seconds. Then..it will hang up automatically and call ended. If someone calles me, that call surely won't go through at all. A few minutes later, MAXIS sent 1 SMS to notify me that a had a missed call.

After a few experiments, I noticed that if I change the mode to GSM only....The calls will be like normal. so, the problems are WCDMA/ 3G network. But I dont want to set it to GSM mode all the time coz I'm using  data plan. 1 more..Internet sometimes are very slow even H+...

I read some forums outside Malaysia..and some of s3 users experiencing this problems..is it because of the recent JB update?

Anyone else experiencing this?Or am I the only one in Malaysia who are having this problems?  =)

and back to the main question.. Is it because of my device or Telco?

I've tried hard reset, change sim card but still no use. I'm running on JB n not rooted...Oh, I live in KL..

Thanks in advance guys..

I am not sure, but you could try. As long as the 2 copper connectors are touching the 2 connectors at the side of the battery, it should work.
