After using Electrum Bitcoin Wallet for so long, I had to try Cake Wallet + Cupcake and it so much better!
If you have an old Android phone sitting alone in the corner of your drawer or shoes box, you can do a pretty easy setup:
Download Cake Wallet on your main phone and load your public key there
on Cupcake in the old phone, load your seed phrase and done, Cupcake is your offline air gapped signer while your main phone is your watch-only and broadcast device.

Oh yea, Cake Wallet is compatible with Spark the newest Layer 2 Protocol which allow you to send Bitcoin through the lightning network but you own the keys to the Bitcoin.

Cake Wallet + Cupcake, transform your old Android phone into a hardware wallet

Valid approach but you forgot the most important part: Flash an air-gapped Android build to the old phone first, or remove the wifi/bt chip.
Without this step, you’re just asking for your private keys to be stolen.
