My Fairphone 2 gets hot
When this happens (particularly around the top area) it means that your processor is working hard and is processing a lot of things at the same time!
Several situations can cause this.
As you may already know, the “brain” of your Fairphone 2 is the Qualcomm Snapdragon 801 processor. It sits right above the SIM card readers, beside the camera, which is where the heat you are noticing comes from. This processor model is known for getting warm when under load
Next to that, the frame and casing of the FP2 are made out of plastic, which does not disperse heat as well as metal.
The combination of these two design choices makes the temperature of the device more noticeable for you. This is nothing you should worry about unless your device reboots unexpectedly. If that is the case, let us know.
Usually when your processor gets warm, several apps and other programs are running in the background. We recommend to occasionally close all apps running in the background to calm down the processor. It might also be the case that there is a third party app running in the background which is causing this to happen. So check for any apps that might be causing this!
When your FP2 warms up when you don't expect it there might be some application(s) stuck in the background. To fix this, reboot your device. A full boot cycle will likely bring your device back into normal working order.
If you think this is happening a bit too often, you can also try a factory reset. This will remove all the third party apps you installed along the way (and your personal data so make a backup!) and excludes the possibility of software causing heating problems.
Make sure your SIM card is not older than a year or dusty and rusty. When the SIM card is corrupt, the processor has to work harder and harder to communicate with it. If you are unsure try out a different (new) SIM card in your device, or request a new one with your provider.
