Is Jolla 1 the only one running btrfs? [answered]
I know that the Jolla 1 uses btrfsand based on the latest comment over here https://together.jolla.com/question/157384/bricked-the-phone-trying-to-balance-btrfs-adding-free-space-via-sdcard/ other devices are supposed to use LVM2 and ext4.
Is that true? I'm especially curios about the Fairphone 2. Couldn't find anything about it other than android phones use ext4 since Android 2.3.
