I find that shocking. To have timetables and learning materials accessible by smartphone is completely expected, even necessary, in a university - but a secondary school?
As for primary, what on earth do kids that age want with a smartphone? But several kids at my son’s primary have had them for some years. DC only just got his first phone (a brick phone) as a new starter at secondary (they must be switched off at all times whilst on the site or the kids face sanctions). He’s only 11. A smartphone is an outright ‘no’ until he’s much older.
As to the Ghey case, I listened to a podcast with tech experts discussing the kind of horrific online content Brianna’s murderers had been accessing. The fact that they even knew where to find this stuff is mind-boggling and the knowledge needed to keep on top of monitoring this stuff is extensive. Likewise, bullying can’t be so easily switched off if a kid has a phone through which they can be reached constantly. It must seem that there is no escape anywhere.
IMO some children are given unfettered access to these things from far too young an age. Esther Ghey is right. Too late for hindsight in her tragic situation but it’s not too late to help others.
