multisig cold wallet laptop, cold wallet android + watching wallet

[francuss]

Paranoid here,

After reading a lot of your docs I am still confused.

Is it possible and does it make sense to set a 2 of 2 multisig, one cold on laptop (no network), the other cold on android (no network), and a watching on a third device?  The plan is to prepare a transaction in watching, then sign it on android connecting the phone via USB cable and finally signing the file with the cold laptop?

If it is possible which minimum Android version is required?

If it is not possible or unstable, would it work better buying some hardware wallet to replace the phone?

Thanks

Fran

Why complicate your life? Just use a Ledger or Trezor hardware wallet with Mycelium on your Android phone.

If you are going to connect the android device to the online PC then it's not going to be cold anymore. But apart from that what you want can work. Look up the minimum version of android that electrum will work with on play store.
