It is protected by a Triluminous glass and X-Reality Engine which makes it shatter proof. It also sports a 20 MP main camera, 2.2 MP front camera, 3 GB of RAM and non-removable 3,100 mAh battery.

Android 6.0 Marshmallow software will offer Xperia Z3 improvements in app permissions, web experience, Android Pay, app link, automatic backup, fast charging capacity, and system UI tuner, among many others.

App permissions give the users the opportunity to individually deny or allow apps asking for permissions. Permission request will show up when the app requires so and not at the point of installation. This gives user full control of their apps.

Web experience has been hugely improved. With the new Chrome Custom Tab, linking to a source will be opened with customization at the top of the window with launching an app separately. This way, users can better interact between apps and websites. This specially designed browser also features sign-in, saved password, auto fill and multi-process security.
