How to Move Apps to an SD Card

Moving apps to an SD card frees up space on your phone's main storage

An SD card is a small piece of removable storage that slides into a slot on your phone. When your phone's built-in storage fills up, moving apps to the SD card makes room for photos, messages, and system updates. Not all phones have an SD card slot, and not all apps can move — but for the ones that can, the process takes about a minute.

Whether you should move apps depends on your phone model and how full your storage is. Moving apps to an SD card is slower than keeping them on your phone's main storage, so apps may take longer to open. If your phone is running out of space and you do not want to delete apps, moving them is worth the trade-off.

Key Takeaways

Only Android phones with an SD card slot can move apps to external storage; iPhones do not have this option.
Not every app can move — system apps and some games stay on your phone's main storage no matter what.
Moving an app takes one to two minutes and you can move it back to your phone anytime.
Apps on an SD card open slightly slower than apps on your phone, but the difference is usually not noticeable for everyday use.

Check whether your phone has an SD card slot

The first step is to learn about your phone can use an SD card at all. Most Android phones made in the last five years have a slot, but some do not — especially budget models and phones from certain manufacturers. The slot is usually on the side of the phone, next to the power button or volume controls, and looks like a thin horizontal line.

If you are not sure, search online for your phone model plus "SD card slot" or check your phone's manual. If your phone does not have a slot, you cannot move apps to external storage. Your only options are to delete apps you do not use, move photos and videos to cloud storage like Google Photos, or buy a phone with an SD card slot.

Insert an SD card into your phone

If your phone has a slot, you need an SD card. You can buy one at any electronics store or online — they cost between five and thirty dollars depending on the storage size. A 64 GB or 128 GB card is enough for most people. Make sure you buy a card that fits your phone's slot; most modern phones use microSD cards, which are smaller than full-size SD cards.

To insert the card, find the slot on the side of your phone. You may need a small pin or paperclip to push the tray out. Slide the card into the tray with the gold contacts facing down, push the tray back in, and wait a few seconds for your phone to recognize it. Your phone will send you a notification when the card is ready to use.

Open Settings and find the storage menu

On most Android phones, open the Settings app and scroll down to find "Storage" or "Device storage." The exact name varies by phone brand — Samsung calls it "Storage," while Google Pixel calls it "Storage." Tap it, and you will see how much space your phone is using and how much is free.

Look for a section labeled "Apps" or "Manage apps." This shows all the apps on your phone and how much space each one takes up. Apps that can move to an SD card will have a button or option that says "Move to SD card" or "Change storage." Apps that cannot move will show "Move to phone" or no option at all.

Select an app and move it to the SD card

Find an app you want to move and tap it. The app details page will show how much storage it uses. If the app can move, you will see a button labeled "Move to SD card," "Move to external storage," or sometimes just "Move." Tap that button. The phone will copy the app to the SD card, which usually takes between thirty seconds and two minutes depending on the app size.

While the app is moving, do not turn off your phone or remove the SD card. When the move is complete, the button will change to say "Move to phone" — this means the app is now on your SD card. You can move it back anytime by tapping the button again. Repeat this process for any other apps you want to move.

Understand which apps cannot move

System apps — the ones that came with your phone like Messages, Phone, and Settings — usually cannot move to an SD card. Large games sometimes cannot move either, even though they take up a lot of space. If an app does not show a "Move" button, the phone will not let you move it, and there is no way around this restriction.

If you need space and cannot move an app, your choices are to delete it, clear its cached data (which removes temporary files but keeps the app), or move other apps instead. Clearing cache frees up some space without deleting the app itself — find this option on the same app details page, usually labeled "Clear cache" or "Storage."

Know what happens if you remove the SD card

If you take the SD card out of your phone, the apps on it will not work until you put the card back in. Your phone will show them as "unavailable" or "not installed." This is why moving apps to an SD card is risky if you plan to remove the card often — for example, if you share the card between two phones or use it as a backup.

If you remove the card permanently and want to keep using those apps, you will need to move them back to your phone first. This takes the same amount of time as moving them to the card. If you lose or damage the card, the apps on it are gone unless you have a backup.

Frequently Asked Questions

Will moving apps to an SD card make my phone faster?

No. Moving apps frees up space on your phone's main storage, which can help if your phone was running out of room. But apps on an SD card actually open slightly slower because the card is slower than your phone's built-in storage. The difference is usually not noticeable for everyday use.

Can I move photos and videos to an SD card instead of apps?

Yes, and this is often a better choice. Photos and videos take up more space than most apps, and moving them to an SD card does not slow anything down. Use your phone's Files app or Google Photos to move media files to the card. This frees up space without the speed trade-off of moving apps.

What happens if my SD card gets full?

Your phone will warn you when the card is almost full. You can move apps back to your phone, delete apps you no longer use, or buy a larger SD card. If the card is full, you cannot move new apps to it until you make room.

Do I need to format the SD card before using it?

Most new SD cards work right away, but some phones ask you to format the card the first time you insert it. If your phone shows a notification asking to format the card, tap yes. Formatting prepares the card to work with your phone. Do not format a card that already has files on it unless you want to erase everything.

Can I use the same SD card in a different phone?

Yes, but the apps on the card will not work in the new phone. You will need to move the apps back to the original phone first, or delete them from the card and reinstall them in the new phone. SD cards are not tied to one phone, but the apps on them are.
