Why don't you use Metamask extension on your phone with extension supported browser? I have been using it since long, and it works for all needs. You won't need walletconnect, since every dapp supports Metamask, you'll be able to connect normally.
I assume you are on android, you can use: Kiwi/Lemur/Mask/Mises, search respective name on play store.
If I was ready to use an extension, I would use it directly on my desktop computer, because it's more convenient to use a large screen and a physical keyboard than a smartphone like an ape.

I'm offended.

And even if a plugin is safe, it can be hacked one day. So I prefer to use a standalone app for connecting Web3 dApps and validating transactions from the dApp. In addition I can check all interactions, I am sure there won't be hidden interactions in the background with the plugin.
