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 2014 Sony Mobile products. As described above, 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™ M2 dual supports the Microsoft standard, Media Transfer Protocol (MTP), which makes it possible to easily transfer content back and forth between your device and a Windows PC. For Apple Mac computers, a special application called Sony™ Bridge for Mac is available with built-in support for MTP. This application can be downloaded from the Xperia™ M2 dual 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:

As noted above, 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. The consequence of such a limit being reached, for example, for the camera application, would be that no new pictures could be taken even if there was still a considerable amount of free space in the application area (or in the user content area). In such an instance, the download and installation of new applications would also not be possible, even if there was enough free memory in the 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 mandatorily and 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, for instance).

D2302 specifications

The Sony D2302, commonly known as the Xperia M2, stands out as a robust entry in the mid-range smartphone market. Launched in 2014, it was designed to deliver a balanced combination of performance, features, and style at an affordable price point.

Under the hood, the Xperia M2 is powered by a Qualcomm Snapdragon 400 processor, which is complemented by 1GB of RAM. This setup ensures that the device can run most applications smoothly, providing a satisfactory experience for users engaging in social media, web browsing, and casual gaming. Additionally, the 8GB internal storage can be expanded via a microSD card, accommodating those in need of extra space for their files and apps.

Photography enthusiasts will appreciate the 8MP rear camera, which brings several advanced features such as HDR and the ability to shoot 1080p video. The camera is supported by an LED flash, enabling users to capture memorable moments in various lighting conditions. The 0.3MP front-facing camera may not be as impressive, but it holds its own for video calls and selfies.

On the software side, the Xperia M2 runs on Android 4.3 Jelly Bean, with the promise of updates for newer iterations, ensuring a user-friendly experience. The device incorporates various Sony software enhancements that enhance the multimedia experience, including Walkman, Album, and Movies applications.

Battery life is crucial for any smartphone, and the D2302 is equipped with a 2300mAh battery that provides adequate power for a full day’s usage on moderate tasks. Coupled with Battery STAMINA mode, it helps prolong battery life by optimizing background apps and reducing power consumption.

In conclusion, the Sony D2302 Xperia M2 offers a compelling package for budget-conscious consumers who desire a smartphone that doesn't compromise on essential features, performance, and style. Its well-rounded capabilities continue to resonate with users looking for reliability and functionality in a competitive mobile market.
