I read an article claiming that on android 6, it is possible to format an SD card as adoptable storage (about time).
I have an ASUS Zenfone, with a PNY 128Gb SD card. I have used an identical card for some time as external storage, but that's not very useful.
First, in settings -> System ->About indicates that the system is running Android 6.0.1
The article claims Settings -> Storage and USB, that I can click on the device, and it will offer to format as internal storage. The only option I can see is portable storage, there is no choice for adoptable. After I format, there are only two choice, eject and format.
How can I get the system to adopt the storage?
I found a video claiming that ASUS disabled the feature, and showing how to use adb and enable it by hand. Before I do this, I want to know if there is any easier way, and if there is any potential problem, including what might happen at the next upgrade.
Last, any idea why ASUS would do something as obnoxious as disabling a major feature like this?
