Welcome to Vodafone Community
I've just installed the Vodafone Broadband app for IOS and this question relates to that, not the My Vodafone app.
It's all working fine but alongside my iPhone symbol on the Devices page (see screengrab below), there's a "heavily-inked and crooked" wireless (echo-type) symbol alongside the normal wireless symbol that all three devices connected wirelessly show.
Can someone let me know what it means please?
I believe it means Beamforming is supported on that device. Checked against various devices connected to our router and that symbol only shows where that is supported.
