I am trying to download [Droid Scan Pro / Droid Scan Lite / Droid Scan Upgrade], but I keep getting a "Download Unsuccessful" message or something similar from the Google Play app. What should I do?
Because app distribution is handled by the Google Play team, not individual application publishers, we may not be able to resolve the issue, but the following procedure frequently works:
1. Power cycle the device.
2. Make sure the device is connected to a WiFi or cellular data network.
3. Retry the download.
See the Google Play Help for the latest information about this issue (http://market.android.com/support/).
