What better way to rain on your competitor’s parade than to release the first major update to your mobile operating system just hours after their event. That’s exactly what Google has done with Android 5.1, an update to Lollipop that includes a few new features as well as improved stability and performance.
For starters, Android 5.1 now allows users to use more than one SIM card on a device with dual SIM slots. This could come in handy if you’re using a pre-paid service while traveling or happen to share a phone with a family member.
The new update for Lollipop also delivers high definition (HD) Voice calls to compatible handsets such as the Nexus 6 for T-Mobile and Verizon subscribers. Other basic enhancements include the ability to join Wi-Fi networks and control paired Bluetooth devices from within Quick Settings.
