Operating system
The Micromax Canvas Turbo runs Android 4.2.1 Jelly Bean, which comes with some skinned elements of the UI like the app icons. The Canvas Turbo has also been given four preloaded themes, namely Mint, Mocha, Raspberry and the default theme that bring minor changes in the phone's colour scheme. The UI of Canvas Turbo features the same setting toggles shortcut that are found in stock Android and adds some of its own as well, for quick access to Airplane Mode, Battery status, Wi-Fi, Bluetooth, GPS, Data connection, Data usage, User (audio) Profiles, Brightness, Screen backlight timeout and Auto rotation.
Samsung Galaxy Grand 2 features the Android Jelly Bean 4.3 OS which works in conjunction with the TouchWiz UI. This makes everything from navigating the UI to opening and shutting apps, very smooth.
Winner: Micromax Canvas Turbo as it is likely to get Android KitKat updates.
