I plugged my phone in tonight with the Samsung OEM charger that came with it. I picked it up and noticed that it was extremely hot. I immediately shut it off but the phone was still plugged into the charger. I immediately got a yellow triangle with a thermometer next to it showing the phone was too hot. I have searched on the internet and see that other's have got this with the S2 through other carriers but no real solution could I find. Some say it's an app like the Barcode Scanner and others say that it's the charging port or battery. Has anyone experienced this with the Boost version? If so, how did you resolve it? I pulled the battery and after the phone cooled down I plugged it back in. So far, it's charging with just a little heat. I do have a couple of news apps that check for news every hour and I have the barcode scanner app.
