I formatted a brand new sandisk usb to ext4 in ubuntu 18.04.2. I have been alternating its use between ubuntu 18.04.3, 64-bit, and debian 10 / armbian, 32-bit. I have been adding files to it until today. 'fdisk -l' is telling me that it is FAT formatted. I am not able to add anymore files.
When I initially formatted it with 'mkfs.ext 4 /dev/sda1', it would not allow me to add any files to it. So I right-clicked on the usb icon in file manager and formatted it by choosing the ext4 format listed there. When I was using the usb in ubuntu originally, I saw a graphical rep of how much space was left, and it showed that it "WAS" ext4.

armbian is that on a single board computer and is that one powered by a 5volt adapter, if so can you measure the voltage at the board to see if it is close to 5.0 volts

Fdisk does not know what file system a partition contains. It only displays a hint based on the partition type code, which does not change when a new file system is created withmkfs. You will have to manually keep these in sync. If you formatted the partition to Ext4, I'm pretty sure it still is Ext4.
