The Samsung Galaxy A5 (2016) launches with Android 5.1.1 Lollipop as Samsung is yet to make the jump to 6.0 Marshmallow. The TouchWiz system adds many proprietary features, but it lacks some key improvements like fine-grain app permission control.
The phone features a capable fingerprint reader, which is, of course, available for securing the lockscreen. It's quite fast (as fast as the S6), especially if you wake the phone with the Home key - all it takes to unlock the phone is to leave your finger resting on the key for an additional split second. This makes using the sensor and its security benefits seamless.
The homescreen is the standard TouchWiz base of operations, which includes the Briefing pane. It's basically Flipboard in disguise (and can be disabled if you don't like it).
The Notification area features a row of quick toggles. S Finder and Quick connect buttons are enabled by default, but you can hide them to free up more space.
Themes are fully supported and there are even A-series exclusives. Themes change wallpaper and icons and modify the look of some stock TouchWiz apps.
The Samsung Galaxy A5 (2016) comes with an average amount of apps pre-loaded. The built-in storage (16GB) doesn't leave much room - according to official specs, the user-available memory is around 11GB, but it may be less in some regions. Good thing you can pop in a microSD card.
The new galaxy A5 also offers split-screen multitasking. While it's better-suited for phablets, this mode allows you to chat with two friends at once or reference a document while writing an email. Not all apps support this split view, but all of the key ones do. The option to put an app in a floating window is not available.
