Which type of screwdriver is typically used to remove security screws on smartphones?

The pentalobe screwdriver is specifically designed to fit the unique shape of pentalobe screws, which are commonly used in smartphone devices, particularly by manufacturers such as Apple. These screws feature a five-pointed star design, which provides increased security against tampering and unauthorized repairs. This design makes it challenging for standard screwdrivers to remove these screws, thereby necessitating the use of a pentalobe screwdriver for removal.

While Phillips and flat-head screwdrivers are prevalent for regular screws found in various applications, they do not fit the pentalobe screws used in smartphones. JIS (Japanese Industrial Standard) screwdrivers can also fit some screws used in electronics but are not specifically tailored for the pentalobe design. Hence, the pentalobe screwdriver is the correct tool for removing security screws on smartphones, aligning perfectly with the requirements for servicing such devices.
