Opinions on buying an old unsupported android phone?

Say I'd buy a galaxy S7 thats no longer supported or even an S8 that soon will be unsupported and don't plan to use a custom ROM.
How bad would that actually be?

I know it'll lack security patches, but how risky is that?

    If you can use a custom image, why not?

    Custom image.

    Security risks in android and _all_ other mobile OSes are severe.

    Be it Apple, Android or whatever tickles ya fetish.

    Attacks can be focused on any part / app of an smartphone - many attack vectors, muey fuckity.

    A non conclusive list:
    - SMS / MMS (e.g. SMS of death)
    - Web (and everything included in Web)
    - App Permissions (e.g. sharing contact lists because of lack of permission system for every App)
    - Bluetooth / NFC / ... (Anything that connects to external devices has flaws)
    - Camera

    A part of it requires your participation... Everyone who says now: I would never do that. Be realistic please. Everyone has this one moment every now and then where brain says: beep and hand pushed the Ok button... Realizing 3 secs later that this was beyond stupid.

    If you put the handy in a lead box, connect it with an external USB cable which doesn't compromise the isolation of the lead box and the connector leads to a secure PC in an isolated environment ... Yeah. Maybe that's secure.

    But pretty non mobile ;)

    Let's not ignore the user-to-root or userspace-to-kernelspace security issues.

    As those are usually kernel or baseband issues, third party images often won't fix it.

    thanks much.
    @iiii voiding warranty and possibly not all features working. That makes a Custom ROM not my preferred Option or at least not straight after buying

    @Jedidja that phone is so old there's no warranty for it anymore...

    @iiii depends where you buy it.
    refurbed.de seems to have 12 or sometimes even 24 month of warranty. Dunno how much would break in such a phone that this warranty will cover, but still.

    @Jedidja Read the warranty details.

    Also just because vendors claim the warranty will be void, it might not be legal (depends on jurisdiction).
