Force reboot your Android device upon hangup

Did your tab suddenly hang? No? Well that’s lucky for you, but mine did, and I wasn’t sure what to do.  With the screen timeout set to 5 minutes, and the extremely good battery saving mode of the device, my Samsung Galaxy Tab 10.1″ was basically unusable. Technically, only the touch screen hung so everything else worked, but I just couldn’t use it. I plugged it in to the charger, to the computer, but no luck. I would have to wait for a week or more to wait until it ran out of battery.

I figured that if I could make it reboot it would be OK, and there has to be a way to reboot the device through USB, right? Indeed. Here’s what to do:

  1. Download and install the Android SDK
  2. Run the android program (located under the tools directory). It will start a the «Android SDK and AVD Manager» (GUI).
  3. Select «Available packages» from the left menu, and install «Platform tools». The installation path is where you unpacked the android-sdk-linux_x86 package.
  4. When it is finished, close the «Android SDK and AVD Manager», and go to the platform-tools directory.
  5. Plug in your Android device via USB. Verify it by running «./adb devices». You should see your device listed up.
  6. Run the following command: ./adb reboot

And voila! The devices reboots! 🙂
