Your charger is connected, but the phone does not charge.

The adapter and/or charging cable may be faulty. Swap these components, if available, and attempt charging again.

First attempt to clean the port. This can be achieved with a dry, unused toothbrush. Compressed air may also come in handy. See guide for more detailed instructions.

The battery may contain one or more bad cells, and is therefore defunct. Replacing the battery may solve the issue. Remove the back cover to access the device’s battery, remove, and replace. (Refer to repair guide for more detailed instructions.)

Bluetooth will not connect, and/or stay connected.

Bluetooth connectivity issues are a general Android problem for some. This was addressed in the 4.4.4 Android update. As such, it is advisable to begin the troubleshooting process with this step.

Navigate to Settings -> Applications -> Application Manager. Scroll right to the “All” tab. Scroll down to locate and select “Bluetooth share.” Scroll down and select “clear cache.”

Your phone will not take pictures; the camera app will not open.

Navigate to Settings -> Applications -> Application Manager. Scroll right to the “All” tab. Scroll down to locate and select “Camera.” Scroll down and select “clear cache.”

Your screen is either shattered or defective in some other way.

Refer to the tear down/repair guide for replacing the ear piece and/or microphone.

Your phone will not place outgoing calls/receive incoming ones.

Power down the device. Remove the back cover of the phone, and remove the battery. Locate the sim card to the top left of where the battery sits. Using a pair of tweezers or a similar tool, gently grab and slide the sim card out. The new sim card should slide in by hand. (Refer to repair guide for more detailed instructions.)
