Like its Galaxy brethren, the Mega runs on Android 4.2.2 Jelly Bean with Samsung's newest custom Touch Wiz layer on top. With this you get Android's multiple home screens, and an expanded quick settings menu when you pull down the notifications tray. Samsung's customized interface offers additional features like S Beam, Samsung's take on NFC sharing, and lots of tools to share data with other devices like your TV, laptop, and tablet.
The basic interface of Mega is same as the Galaxy S4. There are up to seven home screens for widgets and app shortcuts, toggles for commonly used features in the notifications panel, including a brightness slider, and the ability to hide apps in the app drawer or choose to display them in a grid or list format.
The Mega lets you open two apps on the screen simultaneously. It only works with a selected range of apps but the likes of Google Chrome, Facebook, Gmail and Twitter are compatible. Given the huge screen size, you will also like the "one-handed operation" features, which position the dialer, the calculator and the unlock pattern towards the left or right of the screen.
The Mega's software allows you to personalize the lock screen and its short cuts, wallpaper, even LED indicator lights. There's also a call-blocking mode that can turn off a range of notifications and ignore most contacts for certain stretches of time. You'll also find Smart Stay, which uses the phone's front facing camera to determine when you are looking at the screen, refusing to timeout in that case, and Air View, which allows you to hover over the screen with your finger to display extra information.
The Galaxy Mega 6.3 doesn't come with the S4's other software features like Smart Rotation, Smart Pause and Smart Scroll.
There's also an S Translator app that can translate nine different languages using both text to speech and speech to text, and 'Group Play', which can send music photos and documents to multiple devices.
