The Smartphones producer commented that private keys should be stored offline to maximize their security, which means that they should not reside on a mobile phone or any device that connects to the internet regularly.
The blog post comments that mobile phone cryptocurrency wallets are the best place to store "spendable" money due to the phone feature called Trusted Execution Environment (TEE).
Good advices. If you put spendable in the subject title as well, it would not be controversial anymore (but at least I can confirm you have skills how to create click-bait titles)
Haha good point. This thread has drawn a lot of attention just because if its name. I wouldn't ever be so assuming to believe that a phone is the safest place to store anything, let alone a savings account of bitcoin.
Although people have begin to live solely off of their phones these days. A lot of people don't even use computers anymore. They only need access to email, social media, banks, and now crypto wallets. So I guess if it has that much value, you could try to treat it as an account. With a detachable chip for savings, of course.
