trust wallet from play store is my first time to get across of it today, but i believe that your funds is secured provided you have your seed phrase.
Wallet security isn't only about keeping your seed phrase safe. The type of wallet you store your bitcoins is equally as important.
I've had pleasant experiences with TW and Coinomi for years despite being labelled risky. Sometimes, one begins to reason that the issue with closed source thing being risky has to be majorly a thing with the developers going rogue after a while.
It takes only a day to destroy a reputation built for years. Events that have occurred in the forum prove that. For you it boils down to trust. It's your personal decision to trust the developers of a closed source wallet even if you realise they have the power to rip you off at anytime without you knowing. I find it difficult to do that. The only "trust" we have in crypto is the blockchain. That's what separates us from those that believe in traditional currency/fiat imo
