Same keyboard(Logitech K480) is working with Android phone(Samsung A71
5G), how funny this is. Google, pls stop blaming a vendor for your
problem - Bluetooth is Bluetooth, a universal standard and nothing
special.
I just purchased Chromecast 4k and it updated automatically to A12. I
tried to pair with K480 but it does not register pair code. I searched
web and found that this is sort of common issue people reported after
updating to A12.
