I had my new Samsung E715 for three weeks so far, it is a great phone overall. The thing I missed the most are no voice dialing. If you plan to play games or take pictures with this phone, forget about battery life. A few days ago, I was driving home from the mall, and my battery was running low, so I decided to use the car charger. After about half an hour or so, I started to smell rubber burning. I thought it was from the outside, but the smell started to get worst. I was so nervous, thinking my car was on fired. I took a quick peek at the charger and the red light was off, so I tried to pick up the phone, and boy was it hot. I pullled over to a safe place and inspect the phone. From the inside, under the screen and below the word Samsung, there was a burned hole. Then I opened the battery area, and discovered my chip was toasted as well. So, be very careful of charging in the car. I am trying to get Samsung to provide this as a warning, before something bad happen. Luckily, TMobile promised to ship me a new phone of similar value, and my Cell store is willing to give me a new chip. My old phone was a Montorola V60g and I can leave the car charger with it for a long time. If you are curious of my car cigarette lighter being over powered, it is a 1999 Camry LE. Hope this help.
