My new Samsung G-something-or-other just died on me today. Showed it to my daughter (we were out to lunch) - she diagnosed it as having the "black screen of death". \r\n\r\nMe, looking perplexed: "Oh, no!" \r\nHer, unmoved: "YouTube for a hack".\r\n\r\nSo we did, and found a fair quality home-made video where a young man talks the viewer through a factory reboot, and voila! The phone, she is fixed. \r\n\r\nTotes amazeballs.
