I just also got an ATT LTE Note but noticed it gets little warm under the camera when using it. I was wondering if this is normal or something is wrong with it?
its normal. Just like any other electronic device. Heavy usage will make it warm up more. My old phones did that too. I would suggest getting an app to show the internal temp so if it is getting too hot you can stop using it and let it cool down a bit.
"Battery Indicator". Its primary function is to give you a percentage battery notification in the notification area. If you pull down the notification area, it displays the battery temp in either Fahrenheit or celcius. Unless you are bothered by the addition of the battery notification, dl it. Great app.
I use the battery solo widget. It puts a small (takes up only one spot) widget on your screen that tells you the battery level, and if you tap on it, it tells you the internal temp(*C &*F), voltage, health of the battery, etc. Its simple and works well
