I posted this in a wrong forum previously so I will post it here. I was wondering if the Lumia 640 gets very warm or hot when talking? I was interested in this phone, as my current android phone gets annoyingly warm when talking on it.
+1For the money this phone is hard to beat. Maybe the best phone purchase I have made yet.
The operating temperature of the phone is going to vary based on the load it is carrying. If you are running multiple apps in the background, have all the bells and whistles turned on such as Bluetooth, location, Wi-Fi, cellular, etc. – it’s going to run warmer (read: not necessarily hot) than if it were idle. I wouldn’t worry too much about the temperature of your phone unless it’s recently been exposed to moisture or humidity recently. It could be an indication of internals being damaged.
