Cell phones do not have a BIOS like traditional PCs; instead, they use a bootloader, which serves a similar purpose. The bootloader initializes hardware and loads the operating system, but it is specific to each device’s hardware, limiting compatibility with different operating systems. This lack of a standardized BIOS-like system makes it difficult for users to install alternative operating systems and leads to fragmentation in the mobile ecosystem. Manufacturers may avoid implementing a BIOS to reduce costs and maintain control over software updates.
