Google appears to have significantly increased the number of apps that can updated or downloaded simultaneously.
The Google Play Store can now handle up to six app downloads or updates at a time.
Previously, the Play Store only supported three simultaneous downloads or updates.
In the past, if you downloaded or updated multiple apps in the Play Store, you would have to wait as those apps downloaded or updated one by one. Google eventually upped this restriction to three apps at a time, and even tested raising it to four.
