To expand your phone's internal memory, you can format your microSD card as internal storage from your device without any special software. Here's how to do it.

Android phones have an in-built feature known as Adoptable Storage, which enables users to add an extra layer of storage space for music, pictures, videos, files, and so on.

If your Android phone is running out of storage space, many phones will allow you to insert an SD card, which you can set as the phone's primary storage.
