Well, it's stopped downloading those infernal updates so that's very pleasing. It claims to be Android 7 if that is meaningful. But.....tonight I've managed to send a text! It's so much better than my £25 Tesco phone because it guesses what I want to write.
This is impressive. Also - wait for this ....I've done a video call with my youngest grandson.
The other one is old enough to realise his granddad is a total idiot and not worth bothering with.
Thanks for the blocking tip - I shall try that next time.
