Samsung will no longer release software updates for the Galaxy Z Flip 5G and the Galaxy Tab S7 and Galaxy Tab S7+. All three devices launched in August 2020, so support for them is ending after four years.
These devices stopped getting OS and feature updates last year, and now, they will not receive any security updates, either. Samsung promises security updates for devices launched in 2019 and later for a minimum of four years, and while it chose to extend support for devices like the Galaxy S20, S20+, and S20 Ultra into the fifth year, the Galaxy Z Flip 5G, Tab S7, and Tab S7+ are not getting the same courtesy.
Not all Galaxy Tab S7 models will stop getting updates this year: the Galaxy Tab S7 FE will get security updates until at least March next year, as it hit retail shelves in March 2021. However, it's the end of the line for both variants of the original Galaxy Z Flip (the LTE variant stopped getting updates back in April this year).
The Galaxy Z Flip 5G, Galaxy Tab S7, and Galaxy Tab S7+ launched in 2020 running Android 10 and One UI 2.1. They were eligible for three major Android OS upgrades and received the last one—Android 13—back in late 2022/early 2023. They later received updates to One UI 5.1 and One UI 5.1.1, the latter being their final feature update.
