So, this time, all you need to do is remove the battery of the device and press the Power key for 10 seconds to discharge all stored electricity in the hardware components. After you do so, place it back the battery and turn on your device. However, if the issue still happening after the method, jump over to the next step.

After the method, observe closely and see if the issue still happening. If it is, then, proceed to the next option.
Step 3: Perform a reset

The good thing is, this step is very effective and could easily fix if your phone is experiencing software-related issue. But before you do the method, be sure to transfer all your important files and data to you SD card or personal computer.
- Turn off your Galaxy S3.
- Press and hold the Volume Up, Home and Power buttons simultaneously.
- Wait for your phone to vibrate, then release the Power button.
