What is Flash?
Flash, to be specific, is Flashing a ROM. ROM is a file containing executable instructions for an Android operating system and related applications. The stock ROM refers to the Android version that is officially provided by your mobile carrier along with the device. On the other hand, a custom ROM is an Android version that is customized and distributed by other developers. Flashing a ROM means installing a ROM on your phone so that the original Android operating system returns to its primary factory state and can be changed and updated.
Why Flash a Cell Phone?
Some users need to flash a new ROM on their phone to modify the Android operating system of their smartphones. For example to get new features and customizations, remove the bloatware or modify the user interface.
Other users flash their Android phones to keep their devices up to date.
