How to Safely Remove USB Flash Drive in Android

Other than being an open source operating system and being fully backed by Google, one of the reasons why Android has become so popular is that it supports a wide range of hardware. You can see Android smart phones, tablets, and smart watches in many different hardware configurations all over the world. You can even connect your portable USB storage devices such as flash disks to your Android devices through an OTG cable and access their contents right on your smart phone. Since the USB flash disks are now coming in huge sizes as big as 64 GB, this makes it very convenient to expand the storage capability of any Android devices.

While using the flash disks with your Android devices via an OTG cable, you should also be careful when removing the storage media. Just pulling it out may result in data loss, app crashes or some other unexpected behavior in Android. You should first unmount the USB storage media in Android before removing the OTG cable from your smart phone.

Here is how you can safely remove the USB storage devices in Android:

  1. Open the Android settings by going to the home screen, touching the menu button and selecting Settings or Android Settings from the menu that appears.
  2. On the Settings screen, you will see many different settings broken down under different categories. Scroll down the list of all the settings and touch Storage when you find it.Unmount USB Storage Devices in Android
