If you happen to have kids, or you yourself may have come across the scenario of accidentally buying certain things within an application, only later to find out you’ve been charged for something that you didn’t want. Google’s newest Play Store update permits you to stop this by opting to want a password for each in-app upgrade. It’s going to not really stop you, however hopefully it’ll cause you to stop and think about the purchase.
The latest Google Play update permits you to make a choice from the default 30-minute purchase window, and a brand new setting that needs your password with each purchase. There are multiple other additions to version 4.6.16, such as batch install (my favourite), also a new settings and help menu, and security verifications.
You can wait for Google to push the update to your Android device, or head over to Android Police to download the APK.
