Android 5.1 Lollipop is here!
There is also a new operating system from Google, Apple only released iOS 8.2 yesterday. Now Google has also released a new version of Android: Lollipop 5.1. Among other things, an improved theft protection and some bug fixes are included.
Android also has its own support for devices with multiple SIM cards. Until now, manufacturers had to have their own solution for this case programmar There is also an improved voice quality for telephone calls. And other small functions and improvements are added to stability. This allows the user to configure WiFi networks and Bluetooth connections directly via the quick settings.
Improved theft protection
Google has now built a new mechanism into the update: even if a thief resets the smartphone to the factory settings, it can only be used if you log into the corresponding Google account. I don't know if you can get around that somehow.
The update should be available for download immediately, and delivery on Nexus devices will begin these days. The new Nexus devices will likely be the first. When the update arrives on other Android devices also depends on the manufacturer.
