Adding SD Card
I have a Galaxy A03 and I've been reading that this model allows for a new SD card to be added to increase storage space. First, I want to confirm this is correct, then if so I have questions.
First, I'd need to understand how to install the new card and whether it will be in addition to, or a replacement for, the existing card.
Second, how will it affect the phone itself? Once the new card is in, will everything on the phone work as before or will it be like doing a reset?
