Does anyone know why my unlocked galaxy s9 didnt get the November 2019 security update? My friends unlocked galaxy s8 got it.
You could try to search for updates via the Samsung Members App. There's a german topic where someone got his S10 updated although the devive hadn't updated for the last year or so : https://eu.community.samsung.com/t5/Galaxy-S10e-S10-S10-S10-5G/Bekomme-keine-Updates-S10/m-p/1437090...
All updates for the US Unlocked Galaxy S9 Model SM-G969U1 are listed on this Samsung document. I noticed that the document gets updated the day after they release a software update. I can get the update on that day through the Smartswitch app on my PC if I change out my TMO sim with an old (non-active) ATT sim.
This is the latest software update for Model SM-G960U1 (which is the only Samsung factory US Unlocked Galaxy S9 model). This does not apply to any other unlocked models.
