* BlueWallet supports hardware wallets and I think that this could need a special "chapter", especially as Electrum (which OP failed to mention!!!) on Android doesn't support HW
It supports hardware wallet like Coldcard, the Bluewallet make a PSBT and signed on the Coldcard with the use of memory card. Also support cold storage wallet as it can be used as a watch-only wallet to make PSBT which would be signed on the cold storage and transferred back to the Bluewallet to broadcast the transaction. I do not think it support using it with wallet like Trezor, Ledger Nano and some others. Woah, you're right, I've made a confusion.
I wanted to test out my hardware wallet on Android "newer" bitcoin wallets and I thought that BlueWallet was the one this worked with, but no, it was Green Wallet (%!@$ color-names
