I use Electrum in my phone but really do not keep much coins in there. Make sure you keep the passphrase somewhere in a safe place so you can restore it in the desktop version too.
If my phone were to be compromised how would anyone be able to access it?
Not sure about this Trust wallet. But in this kind of cased you have to be the first one to move the funds to another wallet. This is why you need the passphrase to be safely saved in somewhere else.
