The LTE version of the S4 Mini VE has a NXP PN547, which is supported by the nxp-nci-i2c driver in mainline. It seems to detect NFC tags using "nfctool" just fine, although more testing is difficult given there seem to be very few useful applications making use of the Linux NFC subsystem. :( Note that for some reason Samsung decided to connect the I2C pins to GPIOs where no hardware I2C bus is available, so we need to fall back to software bit-banging with i2c-gpio.
