Samsung Galaxy S10+ security patch

when Samsung kicks it out to TMO

What is the most recent security update? I still have April 1 and it's causing issues with work profiles. 

that im un aware of. keep in mind that the S10 is getting a bit older now..not that Samsung wont kick out security patches..but it’ll be a bit slower than their flagship devices updates.

Is there a way to track the status of the Security Path Level updates, i.e. whether Samsung has issued it vs update is pending T-Mobile to roll it out? (I need April’23 update, also required by my employer)

for security patches it would need to be tracked through some other site. TMO only really shows large OS updates and only for the newest variant. so you’ll see info for Android 14 but nothing prior to that and no security patches

The s10's are 8 months away from being end of life.   OS updates and security patches will be sporadic at the best of times.  Think about upgrading to something newer with a more current life cycle.
