This is simple I just worked it out Just follow these steps:
1. I know you may not want to do this but you have to download another app
2. once you've pressed install and when your on the second page of installing it quickly un tick the box where it says automatically update this app
3. although it says "this app" it stops the automatic update for every app
Go to upper right corner where small boxes are (for Apps) and click it.
Click on SHOP in upper right corner of next screen (where apps are)
Click three vertical boxes in upper right corner once shop opens.
Under General is "Auto-update apps - uncheck the box.
There is also an Auto-add widgets and other settings you can change.
open the play store, go to "my apps," once there, to the left of where it says 'my apps' at the top is a menu button. tap on that, then select settings at the bottom of the list, from there the top option is is auto-update apps. tap that, and you get three option, "do not auto-update apps," "auto-update apps at any time. Data charges may apply." and the last one is "auto-update apps over wi-fi only." select the top one, and you're done. LOL took me about three hours to find that particular menu. hopefully this helps someone else save that time. *grin* enjoy.
