New Error code "-25" during application install from Google Play store

Aug 15, 2014
Device is a Xiaomi Hongmi 1SW, the MIUI version is : MIUI-JHCCNBD24.0

Has anyone else seen this error code happen while installing an app from the Google Play store?
The app downloads fine, but then reports this error while installing :
'Unknown error code during application install: "-25"'

This is happening on an app that my company made, and this is the only app and the only device that exhibits this problem. The apk can be installed via email fine.
