I'd benefit from a "Driving Mode" on my phone. If John, Rachel, or Stan calls, auto-text them: "I'm driving, can't talk". Everyone else goes straight to voicemail. If they send me a text within 5 minutes of that call (must be serious), make the font huge so I can read it in .5 seconds on my console. Hide all other texts.

I'd like to be truly responsible and just turn my phone off, but I don't to allow for those few times when there actually is something important.

Interesting idea, but I don't see many use cases. Are people really handing their phones out that often? I only hand my phone to someone else when: * I've asked them to take a photo of me. * They're riding shotgun in my car and need to call a contact or navigate with info readily available on my phone. Neither situation is risk for people snooping around.

It happens to me often enough. Maybe it's just if you have friends who are interested in gadgets, but they will usually say things like, "Oh, you got a new phone? Can I see it?", "Oh, you installed a new ROM? Can I see it?", "Oh, I was wondering how this worked on that phone, can I try it on yours?" All of these are generic requests that just involve tapping around a lot to get a feel for the device, and they're all totally valid requests that one wants to fulfill to help his friends experience more stuff.

Also, some people just don't consider their phones private and don't understand why anyone else would. My parents or siblings sometimes want to flip through Gallery to see the newest pictures of my children, friends, or co-workers.

A couple misplaced photos can be quite the liability in a situation like that...

Earlier quoted context omitted.

Not all games have a separation of user data. Some games basically only have one save slot, so that starting a new game wipes out the save data.

This caused me to be beat upside the head with a Gameboy repeatedly when I was young when I hit "new game" on my cousin's Pokemon Red.

If you were my cousin who did that to me, you wouldn't exist today, to put it lightly.

But if the whole family could share it, they might only buy one instead of four.

Speaking as a father of a 3-year-old, a separate profile for him would save me an immeasurable amount of frustration. "Figure out which folder the program I want is in" becomes really tiring after about the 600th time.

Spotlight could save you that frustration already.

This was done to me by cousins and brothers maybe 4-5 times (with very well developed games before each time). I understand the frustration (although what you describe sounds a bit full on) particularly as I'm pretty sure you had to start a new game then save.

I'm more bewildered to why no tablets seem to have multi-user functionality. In my experience, tablets get shared far more often than phones.

I work for a tablet manufacturer, and I spoke to an Android product manager at I/O last year about this. According to him, this is a feature that pops up once in awhile, but they have a long list of stuff to do and this is just one of those things that always gets bumped out. From my perspective as a platform dev, I'd like to get into some of the technical problems with changing this, but I could end up breaking some…

There are two your account and the hidden root account ;)

"Why Don’t Smartphones Have A Guest Mode?" Because dealing with multiple profiles and/or different profile types is a fucking huge giant pain the ass and a monumental amount of work! Xbox has local, guest, live silver, and live gold accounts. Dealing with all the different profiles and switching between is a nightmare. Urgh, no thanks.

Wasn't this a solved problem... 40 years ago? At least?

Nope. While on Windows, Linux, and OS X you can have two remote users logged in and independently using tty windows, they all must share the same GUI window.

The "two PINs" idea would also be great for when a police officer pulls you over and asks you to hand over and unlock your phone. With the proper encryption you could even have plausible deniability.

Haven't people suggested this with regards to TrueCrypt's hidden volumes, with "rubber-hose cryptography" being the most common answer, and "yeah, well, prove that this is your REAL phone unlock code" being the second most common.

Rubber hose cryptography isn't a valid response to plausible deniability, because it applies equally to a volume that's encrypted normally (i.e. the cops just see junk data). At least you have a chance to throw them off with your fake unlock. Anyway, if it comes down to torture, you're screwed no matter what (unless you're trained to withstand torture); plausible deniability is more for "civilized" courts because they can't possibly prove that you're withholding anything. Personally, I think the 5th amendment in the USA should mean you can't be compelled to decrypt your data anyway, but that's not how the courts see it.
