Download progress notification and Google Play Store showing different progress percentage As the title says, I've noticed that the download progress in the notification bar and the progress in the Play Store shows different progresses. Screenshot:



My question is why does this happen? Is this a bug?

Also, when the download progress in the notification bar reaches 100%, the progress in the Play Store jumps to 100% and the app I'm updating gets updated.
I'm quite sure that this is based on the fact that updates aren't loaded fully but in parts. The notification bar then shows the progress only for what is really being downloaded, the Play Store itself shows the progress for the entire app.
