Software & ADB

5 free tools

For power users and technicians, the real diagnostics happen over ADB and Fastboot. This category builds the exact commands you need without memorizing syntax: generate ADB and Fastboot command lines for common tasks, read and filter a logcat to trace an app crash, and look up the dialer secret codes that open hidden test menus on many Android phones.

These tools generate text and reference information only. They do not connect to or modify your phone, so nothing here can brick a device. Use them alongside the official Android Platform Tools on your computer. Secret codes vary by manufacturer, so a code that works on one brand may do nothing on another.
