Why are you trying to cram another feature into your phone? It already has a great amount of functionality, which makes the phone a multi-tool. As is usually the case with devices that try to combine the functions of many others, the quality of the functionality turns out to be worse. That is, the phone can have a hardware wallet function, but the level of protection will be much lower, and the risk of losing it also increases, since you always and everywhere carry the phone with you in everyday life. This is not suitable for large sums, because you don't carry all your savings with you and is only acceptable for pocket money, the loss of which you can afford. It is better not to combine the hardware wallet with the phone and keep it in a safe place. Moreover, you will rarely use HW anyway.

We'll have to choose between security and reliability between convenience and mobility.
