Play Store app download 100% then starts over to 0% I can successfully download small apps like solitaire, but when I try to download larger apps/games that are 65 MB large, it downloads 100% then it starts over until I go in and cancel the download.

I have plenty of room on my phone and it can download apps (like booster, cache cleaner, etc) from other websites. I also have restarted my phone.

What could it be?
My suggestion is to clear your Play Store data, by accessing the app's info from your phone's Settings, and tapping on Clear Data. Please note that you'll have to reconfigure the Play Store's settings, afterwards.
