As of now, we have not had any unfortunate incidents for TrustWallet users. Perhaps the possibility of users accidentally disclosing their private keys to hackers is greater than the possibility of a security vulnerability within the TrustWallet application.
If possible, a hardware wallet will always be a better choice, even though I have consulted and do not like its unfriendliness during interaction. I am still temporarily using TrustWallet on iPhone and trust it. I will think about buying a hardware wallet from the profits this season to store BTC for the next crypto winter.
Don't think too much about the unfriendliness of using hardware wallets, they are made for higher security and are not concerned with visual appearance alone. and not just about security in the Trustwallet application but the security of the device you use. it will be vulnerable if exposed to malware and you should know that any device can be hacked in ways that you haven't thought of, so you need to be alert about that. Setting aside a small profit for an HW that doesn't even reach $100 is a good idea to do if you care about the assets you hold.
