Memory card slot schematic for the Samsung SM-A22 5G, a 2.77 MB PDF and noticeably smaller than the other sheets of this set. It shows the microSD socket, data and command lines, card detect and the supply powering the card. Useful when the phone fails to read SD cards, letting a technician check the slot supply, ESD protection and signal continuity. Confirm the board is the 5G variant of the Galaxy A22 before trusting designators, since the 4G model uses a different board.
