Samsung’s mid-range Android smartphone, Galaxy Grand Duos (GT-I9082/I9082L) might not see an official Android 5.0 Lollipop update, but you can now download and install the CyanogenMod CM12 Android 5.0 Lollipop custom ROM unofficially from XDA developers on your Galaxy Grand Duos (GT-I9082) and enjoy the latest Lollipop OS version.

Though, the CyanogenMod 12 will give you taste about Android 5.0 Lollipop on your Galaxy Grand Duos (GT-I9082/ I9082L), please note that this is not a fully functional ROM, which means it is not ready to be used as a daily driver yet. A number of things do not work, so use them at your own risk.

      The device received Android 4.2 a year ago. If not got on you check via Keis. If you are technically savvy, download the firmware for your region [] and install via Odin
