Hi @TechnoLogical Unfortunately @Aayan09 is not correct. of the S10 series only the S10 FE will be eligible for Android 13 as that launched later. only 3 major updates were promised for these devices. see more information here https://www.sammobile.com/news/will-samsung-galaxy-s10-series-get-android-13-update/
The S10 FE is also not one of the devices in the initial schedule, so will be a bit of a wait for those with this device.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
