I bought a refurbished HTC one from Ali Express. I can not use netbank on that mobile as netbank shows security warning and netbank app does not work on that phone. But I use that phone to send and withdraw coins from wallets. Is there any possibility to be hidden app or malware that can send my wallet key to someone(hacker)? Is it risky to use that phone for wallets.
Any device can really be possibly be prone to any malware specially you do purchase it online without knowing on whose the real owner.If installing applications and causes some error then if you have doubts then why would you risk? Its better to avoid things rather than on regretting in the end. Even on my smart phone i do know its a brand new one but still i cant entrust the full information of my wallet belongings.
