Q&A for How to Increase Internal Memory of Any Android Phone

A feature in Android version Marshmallow (6.0) and later that allows you to do this. However, not many phone models actually support it, so look up your model before going any further. There are also good reasons to avoid using an SD card as internal memory. If you do, you cannot ever remove the card, or your phone will start getting a lot of error messages and prompt you to reinsert it. Also, using an SD card for internal memory could cause the card to wear out faster and cause errors or slow down your phone.

You need not remove the card. You can share files that are taking up too much space on your phone to another card or phone so that space is freed up.

It might be glitched. Try reloading it or exiting out of the app and rejoin it and try again. Also check to make sure that your storage is not taken up by videos and music.

Samsung phones typically use Micro SD cards, the ones that are smaller than your thumb. There are the standard SD cards as well, but since it's a Samsung, use Micro SD.

Go to your file manager app and type "mp3" in the search bar, then right click it if you're on a laptop or computer, or if you're on an Android device, press and hold it until the menu pops up. It should show the option to delete.

Unless you format your SD card to be an extension of your internal phone storage, I don't believe you can normally store apps on it. Example 6 will show you how to format your SD Card for this purpose. Note: Doing this will require you to delete everything stored on your SD card. Back up your files first.

If you're talking about Method 6, then it should be fine to take the card out of your phone, All you're doing is copying the files to the card, and the card can be removed. Android doesn't necessarily need to have the card to run, as long as you have the files still in your main hard drive.
