I got sold a bad G4. The display starting showing the left and right halves of the screen as separate halves, and eventually stopped working. The touch part still worked, but the display itself wasn't functional. Sprint told me it was a common problem with G4s and LG repaired it for me under the warranty. I think I paid ~$500 USD (~$660 CND) on a payment plan less than a year ago. Back up your phone regularly. Other than that problem, I love it.
