About three months ago, at the same time as the bad news about the security issue of Trust Wallet on iPhone, I got hacked on my Android phone, and all the money I had was stolen! I am not newbie, and I have been using Trust Wallet for more than four years, even with more significant amounts without any problem, a topic that confused me:
You said you used trust wallet on your iPhone but the paragraph after this, you said Samsung. Nevertheless, wallet hacked doesn't have anything to do Witt whether you are expert or you are a newbie, sometimes the things we don't expect are the ones that happen to us without us even noticing the mistake occurring. I just want you to know that I have experience similar experience on my wallet I created from metamask and export to my Trust wallet too before, that was the day I stopped using the wallet because it's an open source software.
The strange point is that the hacker or thief still hasn't cashed out after three months. Even if he/she does, I can't do anything, but it's strange to me why he/she doesn't.
Sadly, All the wealth I had built up over the years is gone, and I don't know what to do.
Sorry for your loss but what chain exactly were you holding your coins even though it doesn't matter, in just skeptical how vulnerable your seed phrase was easy to guess or copied by another person. What I can say about this your possible things that happen is that first and foremost, Trust wallet is open source and is the reason why many developers don't recommend it as wallet and your android phone is open source but android security is very short, you may have a malware of your phone but trust me, you will never know about it. Something most have happened somewhere in your phone.
