Galaxy S9 goes shopping for a new finger scanner, lands in Taiwan

Which one it is, remains unclear, but the source says they have worked with Samsung before, although the supply was focused on midrangers. The current Galaxy S8 fingerprint reader supplier is in danger of losing all of its business, it seems, while the improved scanning is likely to add significantly to the new supplier's bottom line, seeing that Samsung sells tens of millions of Galaxy S line phones each year.
