Install CyanogenMod 12.1 Android 5.1 Lollipop On Galaxy Mega

You don’t have to own a high-end device to enjoy the latest features. If you are a Galaxy Mega user you may be disappointed by the fact that this device won’t receive Android Lollipop officially. Samsung has rolled out the update only for its latest flagship devices but Galaxy Mega isn’t in the lucky list.

It’s a pity that Galaxy Mega wasn’t in the list of devices that will receive further update from Samsung. It has some good specs and it’s a good budget phone. It comes with Android Jelly Bean and later it was updated to KitKat. Unfortunately this phone won’t receive further updates from Samsung.

If you own a Galaxy Mega and want to taste Lollipop the only way is to install a Custom ROM. CyanogenMod 12.1 has landed on Galaxy Mega and you can install it right away. The ROM is based on stock Android ROMs so after installing it your phone will be like a new device. There will be no sing of TouchWiz and those annoying Samsung bloatware.
