OK, there is HONOR 8X. I received a message that the international micro SD card is having problems and needs a backup. It only has Micro-USB (not USB-C), so I used other double-sided flash drives. THEY were so slow and I had a massive backup. It was new and cheap to try. A NOTICE. I HAVE MADE. YOU MUST FIRST DOWNLOAD AND INSTALL SANDISK APP FROM GOOGLE PLAY. WITH THE SANDISK APP, THE TRANSFER SPEED WAS AMAZINGLY FAST (COMPARED TO OTHER DOUBLE-SIDED SANDISK, a clearer model). capacity of this drive. NO! It was at least 50 times faster and easier. I don't know how much this has to do with the drive and the decision to use the official SanDisk app. It probably took 45 hours but I put it on my coffee table and watched TV. Not my OFFICIAL backup, but a good inexpensive add-on or backup of a real backup. My problem is with only one micro USB port on the phone, I can't charge and transfer at the same time. Took a lot of battery life. It's okay, just saying.
