I've seen malware popups that give detailed steps on how to install the app on Android. You can put up all the scary warnings you want but if someone really wants to install some scam app, they will click past everything.

I really wish we could have a simple "don't bother me, I know what I'm doing" switch on these phones but I can certainly understand the reasons why Apple and Google are putting in as many roadblocks as possible to protect users from themselves.

Which is why Google is getting ready to lock down Android.

I wouldn’t mind phones having “Adult” mode that intentionally fails secure net and is completely split off from the standard user space. In adult mode I install what I want.
