Unless things have radically turned around in the last four months, your shilling is bullshit, AC.
Here's a highlight:
El Reg can vouch for this first-hand. One of our offices has an Android 7 Samsung Galaxy S8 handset that, despite being "up to date," can't fetch any security patches since August last year.
An Android 7 Samsung Galaxy S8 obviously being "a 3 year old £50 Chinese phone" from a non-"major manufacturer".
Now please go and try it on with an audience which doesn't know what a shitshow Android updating is because you're wasting your time here.
