But how?? Because there are so many apps in play store who ask for access your contacts, sms, notepads, photos, call history, call recording , location etc.. before installation. If u deny them then u cant install that apps. for installation you have to allow them. Then they can easily access all your data (where you saved your wallet details) which u allowed them. So how can b smartphones are safest way to store cryptocurrencies.
Yes you are right but if you talk about smart phone then may be PC ,Laptop also can get hack. so both are same. But now a days there are more bio-metric verification options available in smartphone which can secure our money. So I think whatever samsung claims is right and i think there should be another button like hardware wallet in future models for conforming transaction for 2FA purpose.
