Tried to do a software update, it failed after the updating apps screen, but now my phone is mental. Trying to turn on WiFi says an application was detected doing unpermitted things and that message comes up every so often on it's own anyway.
Only repair I've seen involves flashing the stock ROM, which requires the USB port to function. Samsung customer service are being dicks and reckon my phone was damaged via user because the logo is fading and the screen has a minor cosmetic scratch in it which has no bearing on the USB port which seems to be failing at an alarming rate on launch models.
Same thing happened with my Samsung TV to be honest, even though that failed outside of warranty. They had to be forced by a large group of people to admit there was a problem with the cheap transistors they used. My TV went before it got to that point so repaired that myself too. Looks like I'm going to have to do that with the USB board, but since this one is in warranty and they're being dicks, I'm out of patience with Samsung products.
Going back to Apple probably. Really enjoyed being away from iOS, but I do love their customer service when shit goes wrong. Just walked into the Apple store, told them my phone went for a swim, dude checked to see if the water damage indicators had gone or would have replaced it under warranty anyway despite my honesty, they had, but still only £60 for a replacement iPhone 4S which was still the latest at that point.
