Short for "Android Debug Bridge." Software that bridges the gap between your Android device and a computer, allowing you to send high-level commands to your phone or tablet over a USB data cable.

• ADB
• Churn Rate
• Stickness
• Lifetime Value
• Acquisitions

A minimalistic screen that shows up when your phone is locked, serving as a quick way to see the time, weather, and pending notifications without having to wake the device. This feature, commonly referred to as "AOD," typically requires an OLED display since the black background doesn't use power and only the white lettering will consume battery on these types of screens. Also called "Ambient Display" or "Active Display," depending on the OEM.

• Always-on Display
• Churn Rate
• Stickness
• Lifetime Value
• Acquisitions

A type of wireless connectivity for battery-powered devices that allows for data transfer at speeds of up to 24 Mbps over a theoretical range of up to 100 meters. Used commonly to connect accessories like headphones and speakers to an Android device.

• Bluetooth
• Wifi
• Cat5
• Hardwire
• Cable

Software with a code base that is freely accessible to the public and licensed for reuse and modification by other developers. Most open-source software is free to consumers and falls under the General Public License (GPL), which allows any developer to modify and redistribute the original work by simply complying with the initial license of the software. Android itself is open source software, with its code base being published in AOSP.

• Open Source
• Accessor
• Method
• Password
• Closed Source

Short for "Android Open Source Project." The base of Android as a whole, which is used by manufacturers and independent developers to create the firmware an Android device runs on. Used colloquially to refer to an unmodified version of Android in some cases (see Stock Android below).

• AOSP
• Windows
• Java
• Python
• Cobol

Short for "high dynamic range." HDR comes into play with two common areas in Android: photography and displays. When a phone has an HDR or HDR+ mode in its camera app, it can capture photos similarly to how the human eye sees the scene, so darker areas won't be underexposed, nor will brighter areas be overexposed. When a phone has an HDR screen, it's compliant with standards like HDR10 or Dolby Vision, enabling it to display more accurate colors and higher contrast in HDR-compatible apps.

• HDR
• LDR
• CIA
• Password
• Emulator

The process of encoding a file in a way that makes it unreadable without a special decoder key. Internal storage is encrypted by default on all modern Android phones, so if an outside attacker removed the storage drive and tried to read it, all of the files it contained would appear as gibberish without the decryption key. For the end user, decrypting storage is as simple as entering your lock screen password, PIN, pattern, or scanning your biometrics. Android devices use one of two encryption methods: full disk encryption (FDE) or file-based encryption (FBE).

• Encryption
• Decaying
• Decrypt
• Password
• Emulator

Short for "embedded SIM" or "embedded subscriber identification module." Incorrectly referred to as "electronic SIM" by some, this is a chip built into a smartphone that can be programmed to function as a virtual SIM card.

• eSIM
