When your cell phone's screen breaks, it is never convenient. Many cell phone users throw away their cell phones, or replace the whole phone outright. While this is not a terrible idea, you can save the hassle of buying a new phone by replacing the cell phone's screen yourself. It is not as difficult as it may seem, and it costs a fraction of the price of a new cell phone. You can purchase a replacement screen online for nearly any cell phone model (see Resources).
Press the power button on your cell phone for about four seconds, or until the cell phone powers off.
Place the phone face down, remove the back cover, and then lift the battery out of its compartment. Set it aside.
