Hi everyone,
I can confirm that it’s a firmware issue and not hardware or iPhone X problem.
In total I had bought 3 iXpand USB 3.0 drives, and one of them works perfectly fine on the iPhone X. At the beginning I bought a 128GB for myself and a 64GB for my busniess partner. The 64GB one didn’t work, so I returned it and bought another 128GB since the first 128GB worked. However, to my surprise the second 128GB I received didn’t work.
So I connected both drives and check the differences, the first 128GB I received had a firmware version 2.60.115.88, while the second 128GB had version 2.60.103.88. But if you use the Sandisk firmware update tool it will not update the firmware to 2.60.115.88, for some reason the tool will say 2.60.103.88 is up to date. I don’t know if I’m lucky to get one drive that came with 115.88 out of the blue, but I hope Sandisk can update their server soon.
Another difference I noticed is the “Card Type”, the first 128GB is type 2, while the second is type 3, I thought they were supposed to use the same type of card for an identical product? Anyone knows the difference between type 2 and 3 cards?
For the record, my iPhone X is running the latest iOS 11.1.2.
