TL; DR
- Samsung has removed the Galaxy S9 series from its mobile security page.
- The Galaxy S9 and S9 Plus will no longer receive security updates, marking the end of all software updates for them.
Samsung will no longer update Galaxy S9 and S9 Plus with new software. The 2018 flagships ran an impressive four-year software update that is now coming to an end.
Samsung has removed the Galaxy S9 duo from its security update page. Samsung had earlier downgraded the devices to its quarterly update schedule, which usually happens when phones are in their last year of support.
The Galaxy S9 and S9 Plus are as far as Android updates concerned after the Android 10-based One UI 2.5 update. You can unofficially port Android 11 and Android 12 on the phone, but for that, you need to have an unlocked bootloader and TWRP installed to flash Noble ROM. However, you may find some features missing and if you do you will see some bugs.
If you decide to go ahead with your Galaxy S9 or S9 Plus, Samsung is offering a lucrative trade-in discount of $ 270 to $ 300 when you purchase the Galaxy S22 Ultra. This is a pretty neat deal for phones so old.
Elsewhere, Samsung downgraded the Galaxy S10 series to a quarterly update from a monthly update schedule. This means you can expect support to end for phones at the same time next year.
