Standard Cell Phone

• 1). Flip the phone over so you're looking at the back of the device (the side opposite the phone's number pad).
  
  
• 2). Remove the cover protecting the phone's battery. The exact method for doing so varies slightly per phone.
  
  
• 3). Take the battery out of its slot on the phone. Leave the battery out for approximately two minutes.
  
  
• 4). Insert the battery back into the phone. Place the battery cover back onto the phone.
  
  
• 5). Flip the phone to the front. Press and hold the "Power," "Call" or another button (depending on your phone) until the phone turns on. The phone should no longer be frozen.
