Operating System Android 5.1 has not introduced any global changes, but Google, of course, has made great efforts to work on version 5.1 and added a few not the most obvious improvements. Those users who have already received their devices to a new operating system can find the list of all the applications point Google Connectivity Services.
If you run this program, the system will display a dialog box prompts you to protect your data when working with open Wi-Fi-networks, connect using Google VPN. Perhaps this means that in the future, Google will get a private VPN-service. So far, however, connect via VPN to implement is not possible.
To get to the dialog box is not so easy - access to Google Connectivity Services was obtained using the utility QuickShortCutMaker. The application itself is located at:
com.google.android.apps.gcs / com.google.android.apps.gcs.WifiAssistantOptInActivity
After the first application dialog prompts you to install VPN-connection, but after pressing OK the system does not find any connection.
It is unclear whether Google will launch this feature, and if you run, then whether it will be available to all or only to a limited number of users. Possibility of VPN-connections can be used in the recently announced project to launch its own virtual operator (MVNO) or through offers for corporate needs of Android for Work , because in this area is undoubtedly important data security.
