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.

I think this is a discussion that is more of technical discussion for those who are more technically inclined can contribute better for a better understanding. Phones sometimes are known to have some security issues depending on the model and the country where its coming from and for this to be a refurbished one, there is high probability that there could be some back end security issues that have been compromised in that regard. I had read a news of US military banning military personnel from using some particular phones because they believed its being used to monitor their movements which then exposes them to danger. If your app is not allowing you to install on it, I guess you should just not install it by force to avoid stories that touch about how you lost all of your coins because of that.
