If you just want to see your transfers, then yes, you can use the watch-only mode. By going to create a new standard wallet -> Use a master key, and then paste or scan your Master public key QR code.
And to get your Master key from your current wallet, you go to the menu -> Wallet -> Information. You'll find it at the bottom.
This is exactly what I do NOT want. This procedure creates/replicates a full wallet.
First of all: I already have a a Standard Wallet on Windows. And I don't care (for now) about Tor connection.
My primary one-and-only focus is to create a watch-only view on Android 13 of an existing wallet on Windows.
After creating a standard wallet on Android and scanning the QR-Code from Windows Screen the wallet is created.
And it is writeable :-((((
I can send BTCs.
So again: How can I create a watch-only wallet view from an existing wallet on other device (Windows)?
