    Answer a few quick questions to evaluate your visit.

    Improving memory performance

    The internal storage stores downloaded or transferred content along with personal settings and data, and it tends to fill up as a result of normal usage. If the device starts to slow down, or applications suddenly shut down, you should consider the following:

    • Close running applications that you are not using.
    • Uninstall downloaded applications that you don’t use.
    • Transfer photos, videos, and music from the internal memory to the removable memory card or Google service.


    • You can purchase a memory card separately.
    • If your device can’t read content on the memory card, you may need to format the card. Note that when you format the card, all content is erased.

    To view the memory status

    • Find and tap Settings > Storage.

    To free up space on the internal storage

    1. Find and tap Settings > Storage.
    2. Tap FREE UP SPACE. If you have a memory card inserted, select Internal shared storage > FREE UP SPACE.
    3. Select infrequently used apps or old files to delete, and then follow the on-screen instructions.

    To stop applications and services from running

    1. Find and tap Settings > Apps & notifications.
    2. Select an application or service, then tap FORCE STOP > OK.

    To format the memory card

    1. Find and tap Settings > Storage.
    2. Tap SD card > (More icon), then tap Storage settings > Format, then perform formatting on the next confirmation dialog.


    All content on the memory card gets erased when you format it. Make sure you first make backups of all data that you want to save. To back up your content, you can copy it to a computer. For more information, see Backing up and transferring data using a computer .

    Smart cleaner

    Smart cleaner improves the device's performance by automatically optimizing storage and memory based on app usage.

    To enable or disable Smart cleaner

    1. Find and tap Settings > Xperia Assist.
    2. Tap Smart cleaner, then tap the switch to enable or disable the function.


    You can also modify, copy or delete files manually if you find and tap the Files application.
