Dumbphones are so dumb. I just used Apple configurator, installed special profiles that block social network sites / news sites and few addictive apps.

If you want you can block all of appstore, block safari etc.

Why would you block uber on your phone? Also I can still use messenger to chat with my friends and don't have to force them to sms me.

Plus I saved money as I kept my iPhone.

I also can take high quality photos and videos.

I can use google maps.

Dumb phones are dumb. Why on earth would anyone buy one?
