This is strange. Maybe like a Windows phone? Where does it get those device metrics? < 2% makes me think it might just be that Androidx86 emulator project.
Tablet list: https://www.intel.com/content/www/us/en/products/devices-sys...
(and there were a lot of small brands that used to make them, that I don't believe get represented in that list)
Having said that, for it to reach >1%, it was more likely a combination of Intel Android tablets (which were fairly common for a while) and Chromebooks.
