My partners phone was on charge, he checked his phone about 10 mins before and it was working. Then 10 mins later nothing, no lights on screen etc wont even turn on.
is there any way to fix this?
If it is sudden death, it will have to be sent into Samsung for repairs. Sudden Death only affects the International version which has a 2 year warranty. The US variants don't get Sudden Death as it uses a different chipset and only has a 1 year warranty. Which model S3 does your partner have?
