Hi,

My brother cant access anything with Google Chrome on his android phone, hence me writing this. All he keeps getting is the connection is not private.
He's tried both 4G and WiFi, switched on and off, the same with aeroplane mode, and the time zones are all correct.
He can't access Google play to download any other browser or anti virus.
Anyone any ideas on what we can do please?

Thanks
Leigh
