The Australian government recalls Google Pixel 6a

A product recall has a specific legal meaning in Australia (and the US).

A recall means the manufacturer and the distributer have a legal obligation to promptly make available a fix and to do so at no charge.

Tesla in the US has also addressed 99% of their recalls with over the air fixes. They're still federally mandated recalls

Edit to add - and failure to promptly provide a fix in Australia means the customer is entitled to a full refund of orginal purchase price - even on many year old goods - which gives the manufacturer a strong incentive to not faff around

I'm guessing it's phrased as a 'recall' because either
A) It's an 'optional recall' and you could return the phone if you want (in which case they will probably just factory reset and update the firmware and give it back to you)
B) The terminology the ACCC uses (possibly must use due to legislation) is old and just doesn't neatly fit the case of a fault that can be addressed by an over-the-air firmware fix
