Don't go too far when it comes to wallet we have lots of them but my most recommended is imtoken which have been using for years Now. Also we have trust wallet and all of these can be gotten from Google Play store, just search on the names you will see them. I can still edit this post again with the links Below. ✌️
both of your suggested wallets are terrible in general and specifically for someone who is looking for a
bitcoin cold storage.
for starters they are both mobile wallets and this category of wallets are always far less secure than a desktop wallet.
secondly they both are token wallets first and then have some bitcoin wallet options. which means they are only good if you want to store garbage in them not bitcoin.
and finally which is the most important factor, both of these wallets are closed source so you literary have zero security when using them. (TrustWallet has some source available but not all)
