I uploaded an app to Google Play Store. But some users reported that they were able to download the app, but unable to install the app. They are getting the error

Unknown error code during application install: "-25"

Why is this happening and what can I do to fix this error?

  • I am getting the same error. did you have any luck in resolving this? what device are you using? (Smasung galaxy S4 in my case). My app is a phonegap app - is this also the case with you?

check to make sure that the versionCode of your new version is not lower then the one you have installed already.

For me this was what was causing the "Installation error code: -25" error on samsung galaxy S3.
