Gallery Lock Pro is a popular Android app that tries to protect your personal privacy by hiding your pictures and videos on your phone.
The app has a stealth mode whereby it is able to hide the launch icon and it can only be launched by a secret code entered in your phone dialer. Once a media file is managed by the app, the media file cannot be viewed in your normal Gallery or Video app.
In the event that your forgot the password, secret code or the security answer, there is a very easy way to recover the media files locked by the app.
Based on my own research, I found out that the app does not really encrypt your media files at all! All it does is to change the file extensions to perform its magic. So if you want to hide a file called img_0001.jpg
, the app changes the filename to img_0001.glk
instead.
The app normally keeps the media files under your internal or external sdcard under /data/.GalleryLock/protected
folder. You should be able to view all the hidden files using the ES File Explorer Manager app. Or you could simply connect your phone to a computer to access the files.
Picture files have .glk
extension and video files have .glh
extension. You will need to rename all the files and your media files should be recovered.
