Since October, I have exchanged my phone 4 times. The 1st day I bought it, I had to return the next day, because it was too hot to touch. The next 3, have had battery malfunctions and heating problems. I know the recent update has been the cause for most of this, so when will they resolve it? I've been patient, troubleshooting all 4 phones, reinstalling all my info 4 times....to then just have another rep tell me, "I'll send you another phone". Help please!!!!
