hi while i was swimming my sister played with my phone samsung s3 and she got irritated and she smacked my phone so hard on the tiles! My S3 got a bit cracked on the bottom part of the screen then i tried to turn it on but the screen was just black!!!! I tried to remove the battery then i tried to turn it on but it was still black!!! So i removed the battery, put it on again then i tried to charge my phone but it cant even show the battery logo charging!!!! Its just all black!!! Please help me!!!!
Dry fone, battery and take out SIM and uSD card. Place in a Tupperware container full of fresh uncooked rice overnight with the lid sealed, to try to extract the most amount of moisture.
Reassemble and try it ... if the screen is still black you should be able to access and download all of your pictures / movies and personal files using the usb cable to a PC ... get all of your stuff off it.
You can put the unit in for the screen to be repaired.
