A micro-SD card is not RAM per se but having one is the most basic way to expand your Android phone’s storage. Just switch your device off then insert the card. A micro-SD card is usually placed in one of the slots of the SIM card tray.

Micro-SD cards are not created equal, having different storage capacities and classes. While it is already sufficient if you have a 4 or 8GB variant, it’ll never hurt to have extra space so feel free to select the size depending on your needs. When it comes to class, though, it is recommended that you use the ones with a Class 10 rating.

The micro-SD card class is indicated by the encircled number printed on the card’s surface. Class 4 to 10 versions are known to work well. It will also benefit you if you use a micro-SD card from a reputable brand to avoid data corruption and other issues.

Transfer Apps to the Micro-SD Card

On the next two app pages, tap Storage and followed by the Change button. You will have to click Move on the export app page and wait for the data to be transferred.

Set Micro-SD Card as Default Storage

Alternatively, you can also make the micro-SD card the default storage of your Android phone if you prefer not to transfer apps one by one. Only Android 6.0 and newer smartphones likely have this function.

To set a micro-SD card as internal storage, first, make sure you have emptied it of files you do not want to lose because it will be reformatted by the smartphone. Once the card is inserted into the device, look for the Storage option in your Android phone’s Settings menu. In that menu, click SD card. See if your phone will show you a “Format as Internal” or equivalent button. Tap on it to finish.

Restart your smartphone after formatting for the settings to work. Note that these instructions are not universal since the steps vary per device model. With these, though, you might get a lead on where to locate the feature.


Other Ways to Maximize RAM

If you do not prefer any of the methods discussed above, the best thing you can do is to maximize RAM even in the simplest ways. You won’t even need to download mobile apps or use a micro-SD card.

Once you see the list of apps currently installed and running on your device, select one that you want to remove or suspend. Clicking on the app from there will show you the app details and the Force stop and Uninstall buttons. Choose whichever is possible or what you prefer to do.

Widgets are typically shortcuts to programs or functions that are already on your Android phone.

There are many kinds of widgets, weather shortcut being one of the most common. The widget shows the weather based on the information the original weather app provides. This is if your phone, like many models, has a weather-checking function or app.

Another popular widget is the music player. It looks like a simplified version of your media player app with just the play, stop, pause, and forward buttons. Some even display album arts. Even if widgets act as good shortcuts for many functions, having too many of those can drag your smartphone’s performance down because they also take up a considerable amount of RAM.
