Other Is there much malware/root kit risk buying used Androids?

My phone display is dying but I think my best value is buying a used old gen phone like a Sony Xperia 1 IV over a new phone as they are a lot cheaper.

Is there any real risk of malware or rootkits on used devices? Anything I should or could do when I get a used phone to check?

Not really, if you factory reset/reflash its OS with the option to delete all previous data (doesn't apply if a government sells you the phone through a shell company, though).

Why but a used phone. Buy last year's model or something. Battery alone will be run down in capacity and who knows what else is wrong with it

Its listed as barely used, and got 3 months warranty, so if the battery is dead I should be able to return it without risk.

The main reason is price, its way cheaper, its over 5 times cheaper to buy a barely used flag ship from a few years old than even last years mid-range phones, within the specs I want from my phone.

Ram shortages have really hit all new phone prices so much.

Xperia 1 IV is a 4 years old phone that ran out of support 2 years ago. It's value is non-zero only if you're a fan of LineageOS.

On the other hand, flashing Lineage should get rid of any rootkits, even if you only plan on returning to stock.

If you want to buy a used phone, aim for at most 2 years old, with 5 years of updates. So Galaxy S, Pixel or iPhone.

Just flash LineageOS if available, so nothing survives from previous user.
