Google promises 3 years only if you buy the device on release day. Our Nexus device at the office got ~18 months.
But yep, the mid/low end devices are often basically abandoned soon after release, or get 1-2 midlife updates so that December OTA has April's security patch level etc.
Or those smart enough to root their device to run a "post market OS" such as LineageOS or postmarketOS. Though the caveat of rooting your device could arguably be less security.
I wouldn't expect any 'normal' user to go though any of this. This is for Android enthusiasts that can get access to good hardware on the cheap and run the latest software.
It isn't at all ideal; it is a hack around the problem of terrible software support in the embedded computer industry. Once you got LineageOS on your phone, you can use OTA updates.
I know, and I very much dislike that as well. That is one of the reasons why I got a Fairphone 2, with long term support.
I also bought a Xiaomi for my partner (cause the FP2 would be an old SoC for the same price it cost 2 years ago) with specs which otherwise would've cost us more than double. I expect the device to last 1,5 years. Hopefully by that time the FP3 is on the horizon.
Yeah but knowing Samsung no phones will get the fixes besides the current flagship and MAYBE the previous one, all too expensive for most people in 2nd world.
And yet the standard advice when anyone buys a Windows computer is to wipe it and install a fresh copy directly from Microsoft to remove all the crap your OEM put on it.
Is is really so strange that the advice for older phones would be similar?
It'll still be vulnerable to a degree then. Android itself will have patches, but the SoC won't because Lineage don't have source code for that, only the binary blobs.
Don't get me wrong, Lineage is great, but fully secure it isn't.
