Sprint galaxy s10 plus, stuck in may security update

[masterq1104]

What happen with sprint galaxy S10 PLUS, no security updates after the last one for may 2019, last update was may 17, no June or July security updates, and this is because of the merger with tmobile ??? what's going on, lately the on screen fingerprint is laggy, did anybody has the sprint June update or perhaps July ???? please help
