On 30 January 2018 JEDEC published version 3.0 of the UFS standard, with a higher 11.6 Gbit/s data rate per lane (1450 MB/s) with the use of MIPI M-PHY v4.1 and UniProSM v1.8.
At the MWC 2018, Samsung unveiled embedded UFS (eUFS) v3.0 and uMCP (UFS-based multi-chip package) solutions.
[20] In April 2015, Samsung's Galaxy S6 family was the first phone to ship with eUFS storage using the UFS 2.0 standard.
According to a Universal Flash Storage Association press release, Samsung planned to transition its products to UFS cards during 2020.
[26] After that, other Android OEMs started using this storage solution on their flagship to upper mid-range category smartphones.
[26] On 30 March 2016, JEDEC published version 1.0 of the UFS Card Extension Standard (JESD220-2), which offered many of the features and much of the same functionality as the existing UFS 2.0 embedded device standard, but with additions and modifications for removable cards.
