    Answer a few quick questions to evaluate your visit.

    Improving memory performance

    Your device has several different storage and memory options:

    • The internal storage stores downloaded or transferred content along with personal settings and data.
    • To get more free internal storage space, you can use a removable memory card or Google service to store your data.

    Note

    • You can purchase a memory card separately.
    • The dynamic memory (RAM) cannot be used for storage. RAM is used to handle running applications and the operating system.

    Your device memory 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.
    • Clear the cache memory for all applications.
    • Uninstall downloaded applications that you don’t use.
    • Transfer photos, videos, and music from the internal memory to the memory card.
    • 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 clear the cache memory for all applications

    1. Find and tap Settings > Storage.
    2. Tap FREE UP SPACE. If you have a memory card inserted, select Storage > Internal shared storage > FREE UP SPACE.

    Hint

    When you clear the cache memory, you don’t lose any important information or settings.

    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 > Menu icon (Menu icon), then tap Storage settings > Format, then perform formatting on the next confirmation dialog.

    Note

    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
