That was three years ago, I haven't changed the configuration but now it doesn't work any more
I was a smart kid at school and in my country they did, at that time, attempt to fast-track such children. This was many years ago and these days they have learnt from their mistakes and handle the whole thing much more sensitively.
It was a disaster for me however - they just advanced me into the next academic year. I could still learn the material with no effort and was still bored, but now I was also the smallest (important when you're age 7 and nobody wants you on their informal games team) and although I was smarter my shaky social skills were now a year behind everyone else's.
Coupled with a few other factors (poverty at home relative to others) it set me back *a lot* in life and I was 30 or so before I really got over it.
tl;dr Teacher, leave them smart kids alone
"Too much choice" might be a real argument in some contexts (such as Linux desktop) but certainly not in the world of Android phones.
Most people don't flash a custom ROM or change the launcher. Literally everyone I know just accepts (and grumbles about) whatever configuration the vendor burnt in at the factory. The more adventurous ones just possibly might create a custom wallpaper or ringtone but that's it.
Unbelievably some don't even know they can install apps, or do know but avoid doing so "in case I mess anything up". Quite rightly they understand that they hold in their hand a complex computer for which they will get absolutely no assistance to fix anything they do which stops it working.
Put your handbrake on if your vehicle is stationary. It is politeness for the guy behind you, so you are not shining a bright red light in his eyes for 45 seconds. Also if someone rear-ends you, and you are forced forward to hit the car in front, then your insurance company WILL ding you for it.
