"will need updating"
I am of the opinion that millions of Android users (i.e. the majority) who are not running OREO will be waiting and waiting and waiting for patches let alone the opportunity to upgrade to OREO.
Makers and carriers in the main can't be bovvered to support the handsets they sell once they have gone out the door or if they do then it is only until the model is replaced by another one.
There are some exceptions to this and if you have one of these devices then you are one of the lucky ones.
Updates or rather the lack of them is IMHO Android's Achillies heel. I know that Google want to change things but it seems like a snail will reach the top of Everest before anything worthwhile is done.
Never mind, all the techy press will be salivating about the latest iPhone tomorrow so this will quickly be forgotten or pushed under the carpet.
Shiny-shiny rulez ok!
