How to Verify File Checksum MD5, SHA1 Directly on Android

Whenever I talk about installing any ROM or system updates on Android from the recovery, I always emphasize checking the file MD5 checksum to ensure the integrity of the file. There are many free tools for Windows using which you can calculate and compare file checksums quite easily.

If you have downloaded the file on your device directly, and you are looking for a way to verify the checksum on the device itself, Android File Verifier is an amazing app that can help you out. To get started download and install Android File Verifier (AFV) on your device and launch it. On the main screen SFV will ask you to select the file you want to check the hash for. Tap on Select File button to open up the list of files and folders on your SD card.

Select File

Navigate to the file for which you want to check the hashing bits and long-tap on it to open the option menu.

Calculate Menu

Select the hashing algorithm you would like to use for the calculation and tap on it. The app with then start calculating the checksums for the file and once it’s finished, it will display the bits as well as copy it to device clipboard.


You can also check integrity of Nandroid backup folders you have created using the recovery by selecting the option to Verify Nandroid Backup on the folder itself.

The tool is excellent for people who regularly flash their device ROM and install files using system updates. Although the comfort level of the app can’t be compared to a windows tool, when you have the file on your device it’s a lot easier to directly check for the checksum bits rather than mounting the device in mass storage mode.
