In My Xperia E3 dual...
problem in play store......
1. When new app downloading...Percentage displayed in notification is differ from play store (My apps).
2. Some times app downloading percentage goes to 150% in notification area...
Settings-apps-all-google play,force stop and clear data.
If that doesn't work then
Settings > apps > all > play store > uninstall updates > restart your phone > try again
