RE: How To Set Up A Smartphone For Cold Storage
another great post! Do you use a dedicated smartphone for this? What are the minimum hardware requirements? Just thinking older phones don't always have access to the latest security patches, getting a very cheap newer model may be safer.
Yes, my phone wallet is a dedicated device. It should be used for nothing at all other than managing your wallet. Regarding the age of the device, newer is typically better but older phones should be ok provided you remove all the unnecessary apps and encrypt it.
