The Abbot website is way out of date and not very informative on compatibility. The most recent Samsung on the list is the s8.
I can report that my s5 works great, but that an s9 i bought had to be sent back for a refund. The nfc on the s9 only works with the libre sensor when battery is nearly full. Drop below around 60% battery and it can't be made to work. I've read that this varies between 55% and 70%. But the s9 i had was as good as useless for going out and about with the libre. I wish there was a place we could all vote yes or no for a range of phones to build up some reliable statistics.
