I successfully installed and encrypted a brand new 128 GB SanDisk Ultra external media card, in my brand new Samsung Galaxy 7, copied photos onto it (tethered to my computer), and accessed them without incident, until today, when suddenly, my pseudo-intellectual phone utterly fails to access the media. I have removed and reinserted the media, rebooted the phone, and run SD Insight to confirm that the media is inserted and is in fact a 128 SanDisk chip, all to no avail. Is anyone else having this issue? Does anyone have a solution? Does anyone want to go to Google and chop down the Marshmallow sculpture in Android's irritating sculpture garden until Google manages to produce a reasonably bug free version of this operating system?
