Question Can't format 128GB SD card as Internal Storage on 128GB Galaxy Note 9

[bighank]

Inserted a new unformatted micro SD card into the 128GB Galaxy Note 9. Went to storage-SD card, and was only given the option to format the card which made it removable or Portable Storage. Looked on Internet and see instructions saying go up to top right 3 dots to select the format. No such option in my Note 9. Removed SD card and inserted into Windows PC and was able to format and access the SD card. It is not bad. (Class 10 v30 I U3). Replaced it in the Note 9 and got same results as before. It is recognized as Portable Storage.

How do I make it Internal Storage?

To my knowledge, you can't make internal storage. Making portable memory will still allow use of the additional memory for apps and general storage.

Expand your Galaxy phone storage using a microSD card

Similar to a thumb drive or other external storage devices, a microSD card lets you store files - but from your phone. Once you insert one into your device and move around your files, you'll have more storage space.
