This is.. not true. A lot of hardware change is involved in modern mobile device security. Apple has come a long way from the iPhone 7 in hardware security and no amount of patching software is going to introduce a new cryptographic coprocessor.
This is true, but most of that hardware security makes the devices harder to access once stolen/confiscated. For everyday use, against online threats, 7 year old hardware can be made extremely secure - it's what Windows 10 and Linux do every day on much, much older hardware.
And sure, a cryptographic coprocessor will make accessing encrypted data a lot more snappy. But decrypting that data in software instead will work just as well, albeit slower. Which really doesn't matter for 90%+ of phone users.
