My Google Play Store application has gone haywire.It is downloading heavily without even notifying anything about what it is downloading and the rate has gone up by 2.5 times in past 2 days.I tried everything to stop it.I selected do-not auto update apps in play store settings and turned off all kinds of Sync.But it still isn't working. Is there any way i can restrict data consumed by my google play store on WiFi? I have a rooted device.
you can start clearing data cache for play store app in .. settings>apps>all apps>play store>clear data.
It would probably solve your issue if it still lingers than remove your google account from settings>accounts>google account>remove this account.
Add again the same account with your credentials.. it would solve the issue.
