The phrase refers to the process of gaining access to the internal components of a device running the Android operating system. This could involve removing the back cover, disassembling internal parts, or utilizing specialized tools. An example would be disassembling a smartphone to replace a damaged screen.
Understanding this process is valuable for repair technicians, electronics enthusiasts, and those seeking to recover data from a damaged device. Historically, accessing the internals of electronic devices was often restricted, but increasing repairability advocacy has led to more readily available information and tools for such procedures. The ability to perform these tasks can reduce electronic waste and lower repair costs.
