I also got the DT-900 this afternoon and used it for the first time tonight. I charged it for 2 hours. I thought the screen was very warm. But when I removed the phone from the charger I realized that the charger itself was only a little warm and the camera side of the phone (which contacted the charger) was not nearly as warm as the screen. The instructions state that it is normal for the phone and the charger to get warm while charging. It also states that if the charger gets hot, you should remove the phone and continue charging after it cools down. Of course, we don't know exactly what their definition of too hot is. It does bother me that the screen gets hot. That cannot be good for the life of the phone. After I finished charging, I tried putting the charger on the underside of a glass table, and the phone was able to make contact with the charger through the glass. So tomorrow I will try charging it that way to see if the phone stays cooler when not making direct contact with the charger. I am not sure this will work, since the charger itself does not seem to get as hot as the phone.
