Disclaimer: I don't use mobile apps as wallet software, only PC, but I can feel your frustration.
I am not a fan of them either, especially not for hot wallet use. But there have been situations where I needed one. I also use Blue Wallet as one of my companion apps for my Jade airgapped hardware wallet. I initially installed it over the Play Store but I know there are alternative ways to download it (like GitHub) if one day it completely disappears from the Store. I also use MetaMask on my Android when I need to have stablecoins on the go.
Yeah I am not really trying to imply that it’s bad, just that people around here have solid knowledge in order to avoid possible scams etc.
And to be absolutely honest I have used BW as well only for watch-only my multisig vault.
Plus if I ever needed to do frequent transactions via LN I would have an LN wallet like Phoenix.
