Home/Snapchat Memories wrong date in Samsung Gallery
One UI / Gallery
Samsung Gallery shows exported Memories as today
Same metadata bug as Google Photos. Gallery is not broken; the export never wrote a capture time into the JPEG.
Copy path
Restore on a computer, USB or Nearby Share the Snapchat-Memories folder, then move JPEGs into DCIM/Camera or a dedicated album folder. Open Gallery → wait for media scan. Dates should match DateTimeOriginal.
