ADB not working or detecting your device on Windows? If Android can't connect via Android Debug Bridge (ADB), fixing this ...

Enter Koush’s Universal ADB Driver for Windows. Koush is the developer behind popular apps for Android devices including ClockworkMod Recovery, Carbon file backup, and ClockworkMod Tether.

The Android Debug Bridge (ADB) driver, contained in WPD, is the universal Android USB driver – plug an Android device into your computer and ADB does the talking.

Google has made ADB and fastboot available as a standalone package, meaning users no longer need to download them with Android Studio or the Android SDK.

Thanks to the work of two Googlers, there are now direct links to the approximately 3.5MB platform-tools folder that includes adb, fastboot, and several other utilities.

Google has started hosting platform tools downloads without the other stuff that are a mere 3.5MB. You can get the platform tools for Windows, Linux, or Mac direct from Google's servers.

Luckily, the latest update for BetterBatteryStats added full support for unrooted phones via ADB commands. There's also better Oreo support and various bug fixes.
