I may have @ the time I put my SD card in originally but I don't recall ever coming across that feature/option. Also, I definitely do not wanna erase/reformat my 128 GB SD card (that's about 3/4 full) to be able to see if that's is/was ever given as an option when putting a brand-new card.
If ANYONE'S able to offer me ANY advice/ideas, tips/tricks, choices/options on this matter as well as ROOTING and/or UNLOCKING for my Samsung Galaxy on5 SM-G550T2 phone.
