It comes with One UI 4.1, March 2022 security patch, support for 5G networks and a new virtual memory feature called RAM Plus, among many others.

MalaysianWireless was able to perform a speedtest and make VoLTE calls while connected to the DNB 5G network via Yes 5G. Among the initial experience include download speeds of over 600Mbps, which can only be achieved via the 3.5Ghz network (N78). Meanwhile we observed slower speeds between 10Mbps to 100Mbps on the 700Mhz network (n28).
Overall, the Internet experience varies throughout the day due to inconsistent signal reception and unstable network performance, indicating that 5G in Malaysia is best suited for fixed wireless broadband service for the time being.

Samsung has said that the new One UI 4.1 update will also be made available globally to Galaxy Z Fold3 and Galaxy Z Flip3, Galaxy A series, Tab S7 FE, S20 series, Z Fold, Z Flip, Note series (Galaxy Note20, Note20 Ultra, Note10+ 5G, Note10+), S10 series, A series and Tab S series.
The update is already rolling out to Galaxy Note 20 5G and the Galaxy Note 20 Ultra 5G users in other countries. It is expected to be available in Malaysia soon and should come with 5G connectivity enabled.
Previously, all Samsung smartphones sold in Malaysia was not enabled with 5G connectivity despite being branded as 5G.
