Made a move yesterday after coming across few threads about coinomi wallet in wallets thread of this forum, missing funds, stolen recovery seeds, some said it's coinomi team, some blame SSL but I don't want this to happen to me, I finally switched to Trust wallet even though it's not fully open source, I hardly heard anything bad about the wallet.
I do not get the full gist as regards the hacked/stolen coinomi wallet; i have been using coinomi for years without any difficulties whatsoever; i keep my btc there.
Its a good move for you; you cannot keep your wallet where your trust does not lie; trust wallet is equally good; i use it for my erc 2o tokens because it is more easier than the coinomi app.
Always do your own research.
