Android 5.1 is a major bug fix release and it was first scheduled to hit the Nexus and the Android One devices. Some of the Nexus devices have received it and now Micromax Canvas A1 Android One device has started receiving the Android 5.1 OTA.
Along with the various bug fixes, the following changes will be observed:
- Multiple SIM-card support
- Return of silent mode
- Device protection
- High-definition (HD) voice calling
- Quick Settings menu that lets users join Wi-Fi networks and control paired Bluetooth smartphones directly
The roll out for the Micromax Canvas A1 will happen in batches. Not all the devices will get it together. You need to go to the Settings >> About Phone >> System Update option and look out for the Android 5.1 update.
The Android 5.1 update will be 410MB in size. Another Android One device – Karbonn Sparkle V is expected to get the Android 5.1 OTA soon.
