Why doesn't Nokia use a FS which is specifically designed to run on flash like UBIFS or LogFS?
Because that device is an eMMC block device, NOT a MTD device. Some years ago people realized it's a lot of fuss to work with MTD-s on the software level (wear leveling ? block management ? addressing ? error correction ? spare blocks ? MLC vs SLC ? CPU overhead ?), and put all this functionality, tailor made for that particular flash device, into something that is known as managed NAND (=aka eMMC).

Take a look for some pretty pictures at

(talks about eMMC around page 55)
