Android One line was created by Google aimed towards countries that cannot afford to buy expensive flagship devices. Android One fixes this as it offers smartphones with decent hardware at a very low price tag. You get a lot for what you pay. That is why Android One smartphones have become so popular selling hundreds of thousands of devices in India and other Asian countries.
Besides having great hardware at a low price, these devices have a lot of support regarding software updates. After Nexus devices, the Android One line is the second one to receive the latest updates. Android 5.1 Lollipop was announced and launched just a few weeks ago and now some of the most popular Nexus devices are already rocking it.
Now the time has come for Android One devices to enjoy Android 5.1 Lollipop. Forum member “ghpranav” has captured the official OTA Zip files of Android 5.1 update for all the Android One smartphones, including Micromax, Karbonn and Spice.
These are the latest builds and come with the build number LMY47O. This build number is much better and more recent than LMY47O. The performance is flawless, with no known problems and users who have updated to Android One have only said good words.
If you cannot install the update using the usual method which is going to Settings > About Phone > Software Updates, then do not worry. You can download and flash the OTA Zip file instead.
