Google has just released the first major Android OS update, and while it's different from many other updates that have generally been skewed toward "stability and performance," the Android 5.1 comes with some excellent features that all Android users ought to know, reports Tech Radar.

Silent Mode Returns

Apart from the excellent additions as well as design upgrades, Android was actually somewhat annoying, especially because Google removed the silent mode. In other words, users could no longer get LED notifications without their phones making some kind of audible sound. Fortunately, Android 5.1 has restored the silent mode, which was so loved by the users.

Repairing Shoddy Wifi

Android 5.1 has fixed the problem related to poor Wi-Fi, which has been a nightmare for devices running on Google's OS. Now, when Android 5.1 users connect to any network, their phones will remember this black sheep connection like a terrible nightmare and will not auto-connect to it in the future. Although a minor feature, this is indeed a great one.

Safe Browsing

Apart from ensuring that the users never get an unnecessary Wi-Fi network, it is likely that Google is working on a VPN service to enable them to browse networks more securely. Although, for now, this is just a rumor, Pocketables has detected a new app sheltered in the All Apps folder dubbed as "Google Connection Services." When it pops open, the app reportedly greeted them with "To help protect you on open Wi-Fi networks, your data will be transmitted securely through a Google VPN." Keeping in view the fact that the new app was discovered on a Nexus 6, apparently the only device that will be in harmony with Google's upcoming wireless service, it is possible that the Mountain View-based tech company is waiting for this service to roll out first.

Anti-Theft Game

In addition, Google is also augmenting its anti-theft game, in any case for Nexus 6 and 9. Android Police reports that a new anti-theft feature would make it difficult for a potential thief to replace the user's account as a primary account, with any accounts of their own, and have access to the phone even if they wipe it and attempt to login with their own credentials. As of now, it seems that the roll out will be somewhat restricted, but users can expect Google to offer this feature to more smartphones in the future.
