I have the same problem with the Sony Xperia Z3 and Vodafone. It is the Amazon App 2.10.0 integrated into the system. I have stopped this, disabled and restarted. Innately appears in PlayStore "Amazon shopping". When I suggested above, select the link to Amazon DE, the following message appears after the installation:
Error!
Duplicate provider authority
When I use the app at Amazon.com: Amazon wants to install app for Android (Security: Allow unknown source) appears at the end of the installation the message:
Application not installed
If I choose Amazon shopping, this is installed. But the instant Vodeo player will then perform an update for Amazon, which is not carried out. This problem is described several times in the above combination in the net. Unfortunately I can not get any help from the friendly hotline. The problem is well known. Too bad that Vodafone no help is to be expected. Now I'm standing there with your Android phone No.1, with which I can not watch videos.
****************
The problem is solved:
1. Open Play Store
2. Navigate to "My Apps"> "All"
3. Browse Apps for "Amazon" (Vodafone) NOT "Amazon DE" or "Amazon Shopping" and call the entry
4. Select Refresh
