Steve, that sounds like the same Samsung A04 64GB detailed in the OP. Right? So even if the seller has not upgraded, you will be able to upgrade and/or it will push out automatically. Depending on the country, maybe the cell provider. Red responded that the phone has already received the “Android 13-based One UI 5.0 update“, but I figure samsung will auto send the 5.1 update soon. Then sometime over the next year or two the phone will get an update, maybe including Android 14-based (these cheap phones are the slimmed down android-based).
My statement about security during the years when a phone stops getting updates is intentionally exaggerated. Yes there is risk, but it is less if you keep aware, and follow known good advice for secure phone practices. Unless you are directly targeted somehow/some reason. Since any low-tier phone will be slower in two years after the upgrades have further bloated from the original, the best is to remove almost all 3rdparty apps at that time.
