    Some newer phones allow you to insert an SD card using the SIM tray, but some, including the popular Samsung Galaxy lines, offer instead large internal storage and no space for an SD card. [1] If you can't find your SD card slot, check your Android's manual to make sure the feature is supported.
    • Locate the oval-shaped compartment that has a pinhole on the right, then turn off your Android. Insert a paperclip, pin, or the SIM tray tool that came with your phone into the pinhole and press down to eject it. Place a micro SD card in the tray and reinsert it. If you don't see the space for your SD card and only see your SIM card, carefully flip the tray over to see if the SD space is on the back.
    • If you have a new SD card, you can insert it and will be prompted by Android to format it, according to Oppido.
    • Warning: Formatting an SD card will erase all data on it, and you will not be able to recover it. Make sure you back up all data you want to keep on the SD card before formatting it.

    According to Oppido, if your phone doesn't immediately prompt you about the SD card, you can go to Settings to format it manually. To do so, swipe down from the top of the screen to display the Quick Access menu. Tap the icon that resembles a gear in the upper-right corner.
    • Alternatively, you can open the Apps menu and tap the icon that resembles a gear.

    This is usually sandwiched between "Battery" and "Sound" if your phone supports an SD card. According to Oppido, you'll find the option to manage your SD card here.

    The name of it will vary depending on the manufacturer of the SD card, like SanDisk, or any personalizations you made.

    Here you need to choose if you want to use the SD card as internal storage or if you want to create a portable device.
    • Selecting Internal Storage - If your phone has a very limited amount of internal storage, this might be the option you're looking for. You can't install apps, but you can save data, including files, photos, and videos, to this card. This setting is not available on every phone, and you cannot use the SD card to transfer files from one phone to another .
    • Selecting Portable Storage - If you have multiple devices and want to be able to share data using your SD card, this option is for you. You can't install apps on the card, but you can save files, photos, and videos and move them between devices. [2]
      • Tap Format SD Card in the pop-up to confirm your choice.

    I have done according to the suggestion, but only could delete everything on the card, not format it. What else should I do?

    Remove the memory card, insert it in a USB card reader in your PC and format.
