Aftermarket tinkering on Android phones isn't as prominent as it once used to be. That's not to say you can't root your Android phone or install a custom ROM like LineageOS on it. You can still tinker and customize your phone to a large extent as long as you have the interest and the technical know-how. Most — if not all — aftermarket tinkering requires you to connect your Android smartphone to a computer using a USB cable, so you can use tools like the Android Debug Bridge (ADB) to interact with the device.
