I am in the process of purchasing a used Android device through eBay. Assume I receive it, it is exactly the model I expect, it appears to work, it is not encrypted, and it is not stolen, etc.

I am planning to do a factory reset on it when I receive it. Is there anything else I should do to ensure that it is not rooted and that no malware etc. is present? I don't know enough enough about rooting to know for certain that a factory reset will eliminate that.

If I were selling one, I know I should encrypt, perform a factory reset, and possibly load with data and perform another factory reset.

Thanks,
