I recenty came a across a doubt...

Can a smart phone be used in space?

Obviously you aren't going to get any data signal, but will the functions like touch screen, GPS, accelerometer, vibrator, etc, work? Will anything get affected by gravity or no air?

    $\begingroup$ So you mean in a vacuum, not in a space station or something? $\endgroup$ Commented Aug 24, 2016 at 22:22
  • $\begingroup$ googlemobile.blogspot.com/2010/12/android-in-spaaaace.html (pressure at this altitude is approx 0.16 psi) $\endgroup$ Commented Aug 24, 2016 at 22:24
  • $\begingroup$ It would probably work fine as long as there was some sort of atmosphere, but in the vacuum of space, probably not so much, as air makes a pretty good dielectric. Granted smart phones don't work with very high voltages, but the space between runners is so small, it probably doesn't take a lot of voltage to arc between them in a vacuum. $\endgroup$

    $\begingroup$ GPS won't work, they're designed to stop working at high altitudes and high velocities so you can't use them to make ICBMs. See this: support.spectracom.com/articles/FAQ/… $\endgroup$

Multiple android based phone satellites have been launched into space. (At least six according to Wikipedia). I haven't looked into which components they tried using in orbit, but the camera obviously worked.

No. Take an ordinary smartphone and put it in outer space and you've got a big problem: Inadequate cooling. The phone is going to destroy itself with its own heat. Normal conduction and convection cooling will not work, all you have is radiation and at those temperatures it's a small part of the cooling.

Also see this answer to Do Phonesats and GoPros work with their internal batteries in space vacuum?

  • $\begingroup$ So how does this information apply to the ones that have been successfully placed into space / near vacuum? And still worked? $\endgroup$ Commented Aug 25, 2016 at 22:50

    $\begingroup$ @OrganicMarble What are you talking about? Nobody's launched a bare phone. Now, a phone in a larger system can use that system as a heat sink--it's no longer in outer space but in a satellite. $\endgroup$ Commented Aug 25, 2016 at 22:52
  • $\begingroup$ googlemobile.blogspot.com/2010/12/android-in-spaaaace.html says they launched Nexus 5 phones in styrofoam coolers. $\endgroup$ Commented Aug 25, 2016 at 22:55
  • $\begingroup$ @OrganicMarble That's a high altitude balloon, not space. The atmosphere is thin up there but it certainly exists. $\endgroup$ Commented Aug 25, 2016 at 22:58

    $\begingroup$ @OrganicMarble At the very least, the LCD display would stop working. Turns out the L in LCD stands for Liquid. $\endgroup$

As an addendum to the other answers, the GPS in a typical smartphone will not work in space--or more specifically orbit--because consumer GPS units have restrictions placed in their firmware which prevent their functioning above a certain altitude and/or speed. A military or scientific-grade GPS would still function though, and GPS is in fact used by many satellites and the ISS.

  • $\begingroup$ by that logic, the GSM system also wouldn't work because it'd be out of range of GSM networks which are earth bound and have antennae carefully designed to minimise radiation upward in order to conserve power. $\endgroup$
