help - buying used/second hand phone .. what to check?

[InGearX]

I'm lost my phone and I'm going to get a used android (I think Galaxy s3 again)

please help me compile a list of all the big and small and tiny things I should check before giving cold hard cash forever ..

list:
* microSD slot
* wifi
* making a call
* headphone jack

* clean ESN/MEID - if in USA
* call - gives you a decent indication of whether the earpiece speaker is blown or not and if the mic has gunk clogging it.
* Make sure it has an OEM Samsung battery.
* Make sure the screen doesn't have any hairline cracks.
* GPS works properly
* Make sure the screen doesn't have any hairline cracks. Also power the screen on to see if the LCD/Digitizer assembly was replaced with a cheap shit knock-off third party
* sensitivity of the touch
* Check all buttons to make sure they function correctly
* Check the water indicators if present to see if they're pink.
* Check the charging port to make sure the solder isn't broken and the phone isn't shorting out.
* Lastly, check the cameras to make sure they function, focus correctly, and produce a clear image.

thank you ..

Expanding on that:
Meet your seller at the phone store and have them verify it's not stolen. Then have the phone transferred into your name while the seller is still there. After that they can't report it stolen.
