So I'm on T-Mobile US, and my wife has been having issues with her 8x. I called T-Mobile and they determined that the problems are due to faulty hardware so they offered a warranty swap, but they're asking $20 for the exchange in addition to shipping costs! I know it hasn't always been this way because I had to exchange my Touch Pro 2 back in the day and I only had to pay for shipping. I've never heard of charging a fee for warranty exchange! I understand if it were an insurance claim, but this is due to faulty hardware and 100% out of our control, so what gives? Does anyone know if other US carriers charge for this? I'm considering ditching T-Mobile near the end of the year once our contract runs out, and this issue may play a role in deciding which carrier to go to next.
