Product overview

Highlights

• The world’s first smartphone with a 4K HDR display

• 19MP Motion Eye camera

• Super slow motion video at 960 frames per second

• 13MP wide angle front camera

• IP65/68* water resistant

• Smart Stamina

• Xperia Actions intelligently learns and adapts to your usage

19MP Motion Eye camera

Motion Eye camera is the latest camera system developed with Sony Digital Imaging know-how to
capture motion beyond human eye capability, powered by the world’s first memory stacked image sensor
in a smartphone**.

• Super slow motion***

The new Xperia XZ Premium is the first smartphone with 960fps video capture***. This means you can
capture the action 32x slower than with normal video.

• Predictive capture

When the action starts, the Motion Eye camera starts buffering to automatically capture up to 4 photos
from before you press the shutter, to ensure you capture those unexpected moments.

• A breakthrough in clarity and quality

1. Superior image quality powered by a brand new 19MP memory stacked sensor and a redesigned
Sony G Lens.

2. With 19% bigger pixels, the new sensor can capture more light and detail.

3. For fast moving objects, Anti-distortion shutter reduces misshaping of the image.

The world’s first smartphone with a 4K HDR display

Using Sony BRAVIA TV technology, the Xperia XZ Premium plays 4K HDR content that’s so clear and
lifelike, it takes your breath away.

Because TRILUMINOS Display for mobile selectively maps colours from a wider palette, all of life’s subtle
shades are preserved. Even reds, blues and greens, which are typically hard for screens to show
accurately, look vivid and realistic.

*Xperia XZ Premium is water resistant and protected against dust, so don’t worry if you get caught in the rain or want
to wash off dirt under the faucet, but remember that all ports and attached covers should be firmly closed. You should
not put the device completely underwater; or expose it to seawater, salt water, chlorinated water, or liquids such as
drinks. Any abuse or improper use of the device will invalidate the warranty. The device has been tested under an
Ingress Protection rating of IP65/68. For more info, see www.sonymobile.com/waterresistant. Note the Xperia XZ
Premium has a capless USB port to connect and charge. The USB port must be completely dry before charging.

Memory in Android™ devices

To use Android devices efficiently, users should be aware of the different types of device memory. This
knowledge is important in order to understand, for example, where data such as music, photos and
videos is saved; how many apps can be downloaded from Google Play™; and how photos can be copied
to a PC.

Information regarding memory presented in this section may be useful to developers when optimising
applications for mobile devices.

Generally, all Android devices share the same basic memory setup. What differs is how much memory is
available to you via the different types of memory, and whether your device uses an external SD card or an
internal memory chip. Any information specific to the particular device model described in this White
Paper is noted as such.

19 February 2017

White paper | Xperia™ XZ Premium

Types of memory

The types of memory described and numbered below are consistent with the terminology used in Sony
mobile device menus and in other content relating to 2017 Xperia™ devices:

1. Dynamic Memory (also known as RAM) is used by applications that run when the device is turned on.
The amount of Dynamic Memory influences how many applications and operating system services can
run at the same time. The Android operating system automatically closes applications and services
that are not being used.

However, such automatic functionality has limits. For example, if a lower amount of free RAM is
available to applications after a new release of the operating system (due to increased capabilities in
the system), device speed will eventually be impacted. This is the main reason that a device cannot be
indefinitely upgraded to newer releases of Android™.

If you experience problems with RAM, for example, if the device runs slower than usual or if the Home
application restarts frequently when you leave an application, you should minimise the use of apps that
run all the time. Social networking apps that connect and update their data online and animated
backgrounds are examples of apps that are always running and affect RAM performance. To minimise
RAM issues, you could also consider using a static wallpaper instead of a live wallpaper.

To see which apps and services are currently active, go to Settings > Memory. You should have at
least 50 MB, and ideally 100 MB or more, of free RAM to avoid slowdowns and application restarts.

You should also be aware that if you update the device to a later Android release, the load on the built­in Dynamic Memory will increase due to the addition of more features. As a result, the device may run
slower after an update.

The Xperia™ XZ Premium has 4 GB of RAM available to the Android OS and any installed applications.
200 MB of the total RAM is in use during normal operation when the user starts using the device out of
the box.

2. System Memory (also known as “System partition” or “/system”) is used for the Android OS and for
most applications that are pre-loaded from the factory. This type of memory is normally locked, and
can only be changed through a firmware upgrade. There is usually some free space available in this
section of memory. However, since it is locked, you cannot save apps, photos or any other content to
this memory. System Memory is reserved for future firmware upgrades, which almost always need
more memory than the original firmware. You cannot see or influence the use of this memory.

3. Internal Storage is referred to as "working" memory. It can be compared to the C: drive on a PC or to the startup disk on a Mac.

This type of memory is used to store all application downloaded from the Google Play™ Store (and
other sources) as well as their settings and data (such as emails, messages and calendar events, for
example). All applications have an allocated area for application data. Memory dedicated to an
application is inaccessible to other applications.

Some game applications also store content such as game music and game level information outside
their own designated area. In most cases, an application can choose to save its data in a location of its
own choosing (outside the protected application settings area). Generally, such content is not deleted
when an application is uninstalled; it must be removed manually by connecting the device to a
computer with a USB cable, or by using a file manager application.

Internal storage is also used for all added user content. For example, photos taken using the device's
camera, media files downloaded from the Internet and file transfers are stored in this area. Typical user
content includes:

•photos

•movies

•music

• Email attachments

Internal Storage will tend to fill up as a result of normal usage. Devices with a large initial Internal
Storage can handle more applications and store more user content.

If the Internal Storage starts to get full, the device slows down, and in some cases it might no longer be
possible to install more apps. You should always ensure that you have at least 100 MB of free Internal
Storage. If not, you should consider removing some apps that you seldom use, or move content that
you do not frequently access to external storage.

You can see approximately how much Internal Storage is free in Settings > Storage & USB. You can
also view more details about how much memory is used by applications under Settings > Apps. In
the Xperia™ XZ Premium, about 49.31 GB of Internal Storage is available out of the box.

Please note that in Sony Mobile 2017 products, “Internal Storage” is now the combination of what was
previously known as “Device Memory” or “Phone Memory” (for applications and their data – also
previously known as “/data”) and “Internal Storage” (for user’s content – also previously known as “/
sdcard”). The changes in Internal Storage were made so that memory usage could be more flexible
and to allow encryption of user content.

Memory card slot

Some products include both a large internal memory and a built-in memory card reader. Android manages
devices with a built-in memory card reader and internal memory differently from a device that includes
only a built-in memory card reader.

Since most applications expect only a single location for storage, such applications will not generally
allow you to SAVE anything to the memory card (i.e., they do not offer the option to choose a storage
location). However, some applications (for instance, the Sony Mobile “Camera” application) may actually
allow you to do so. Other applications, for example, backup applications such as the Sony Mobile
“Memory” application, will by definition be configured to copy content from the Internal Storage to the
external SD card.

On the other hand, when it comes to reading from an external SD Card, you will be able to access content
(for example, videos, photos and music) on a memory card inserted in this slot without any special
consideration since the Android system searches all available memory for content. Therefore, such
products may be regarded as supporting a fourth type of memory, called “External Card” or “SD Card”.

4. SD Card (known as “/ext_card” from a programmer’s point of view, or by other names in other Android
products) is the name for the removable SD memory card in all 2017 Sony Mobile products. As
described in the previous section, this External Card memory is generally more limited in that any
application can read from it, but many applications cannot save to this card. Only a few applications,
including backup applications and file manger applications, have the capability to save to this card.

Backing up data to different memory types

Generally, you should not save photos, videos and other personal content solely on the internal memory
of a device. If something should happen with the hardware, or if the device is lost or stolen, the data
stored on the device’s internal memory is gone forever.

In a device where an SD card reader is the main memory, it is relatively easy to take the card out and copy
all content to a PC or Mac, or to an entertainment device with a memory card slot. In a product featuring
Internal Storage as the main memory, it is not possible to physically remove the memory. Instead, any

critical or high-value content must either be copied to an external SD card by a special backup
application, transferred to remote storage over a network (mobile or Wi-Fi), or to a computer via a USB
cable.

To facilitate the transfer of data via a cable, the Xperia™ XZ Premium supports Media Transfer Protocol
(MTP), which makes it possible to easily transfer content back and forth between your device and a
Windows® PC or an Apple™ Mac® computer. This application is called Xperia™ Companion and it can
be downloaded from the Xperia™ XZ Premium support page.

Note that you do not need to back up or make a copy of applications that you have downloaded from the
Google Play™ Store. They can normally be downloaded again after you have set up your Google account
to work in a new device (or in a device where the memory has been completely erased).

Note 1:
Some Android devices, including Sony Mobile devices from 2012 and Sony Ericsson devices from 2011
and earlier, do not use a single “Internal Storage” for both applications (and their data) and user content.
Instead, these devices use either an external SD card for user content, or a corresponding area of internal
memory to reproduce the functionality of an SD card. In such devices, there is a fixed limit between the
application area (“/data”) and the user content area (“/sdcard”), with the result that user content can build
up and reach this limit. When the user content reaches this limit, no additional data can be added using
any application. For example, the camera application would no longer be able to capture additional
photos even if a considerable amount of free space was available in the application area. This limit also
applies to the application area. Downloading and installing new applications would not be possible even if
there was enough free memory in the user content area.

Note 2:

Some devices with integrated storage have abandoned the distinction between the application area and
the content area when it comes to a Factory Data Reset. As a result, there is no option in such devices to
perform a Factory Data Reset and preserve content. In such devices, all content is completely deleted
from the device when a reset is performed.

In contrast, Sony Mobile’s memory integration solution makes it possible to preserve user content in this
situation. Therefore, when performing a Factory Data Reset, the default action will still be to only remove
applications and their data, and an option box must be checked if all content is to be removed as well (as
might be desirable when selling the device second-hand).

Note 3:
For a developer, it is important to note that from a programming point of view the location names used to
refer to the different memory areas described in Note 1 are still valid, i.e., the area used for applications (“/
data”) is still present, as is the area used for content (“/sdcard”).

In reality, “sdcard” is a “symbolic link” to “/storage/self/primary”. However, from inside an Android
application, “/sdcard” can still be used. For example, you can use “sdcard/DCIM/100Android” to find all
camera images. The continued use of “/sdcard” to access the content area ensures compatibility across
different products and Android releases in this regard.
