About the bug on Trustwallet, someone complained it to me, but the person was able to send all his coins out of the wallet into another wallet. It is a bug. Still also good to know that a close source wallet should not be used, not because of this particular bug because an open source wallet can have such bug and be fixed, but because you do not know the kind of vulnerabilities that the developers may intentionally included into the wallet code, like spyware etc.
I just want to remind that anyway Trust Wallet is owned by Binance, the biggest exchange in the world, which makes a ton of money every single day so I'm not saying that we should 100% trust them but I find very hard to believe that they would jeopardize all what they've built over a wallet spyware, it makes little sense to me.
And just to be clear, as I said before I use Trust Wallet just to receive the bounty rewards, it's not my main storage wallet, I just prefer it for small transactions using the smartphone.
