Get Broken Screen Data Recovery old version APK for Android
This app aids in retrieving data off a device with a broken screen.
If you've cracked your screen and you want to copy the data off the device but you can't type in your unlock password, this should help you.
What you need to do is install this from Google Play, and push it to install on the device with the broken screen.
This requires the partner App "Broken Screen Recovery Client", which will pull the data.
