If you happen to own Lenovo's S60 mid-ranger, here's some good news for you. The Chinese company has just started rolling out the update to Android 5.0 Lollipop for this particular device.
Although it was made official this year, the Lenovo S60 launched in March running Android 4.4 KitKat, many months after Google unveiled Android 5.0 Lollipop.
Now though Lenovo is rectifying that error by releasing this update. The new software version has so far been spotted in Greece.
The rollout is happening over-the-air, so it might take a while for it to reach all devices out there. Rest assured however that your handset will notify you when it's ready to install. The download is a hefty 1.32GB affair, so you should probably make sure you're connected to Wi-Fi before grabbing it. You aren't supposed to lose data during the update process, but it's always safest to create a backup beforehand.
