I actually used the microSD to SD adapter before in my old Galaxy Note 3. Since the Note 3 had a removable back which you could use to access the both the battery and microSD card slot unlike most phones today, I replaced it with one normally used with a Zerolemon extended battery, and used it with a 512GB SD card since microSD cards did not come in sizes that large at the time.
