I need to take screenshots on my phone like for instagram and twitter and stuff but i downloaded a few they either dont work or i dont know how to take them on this phone anybody know anything??

[Gracie]

wait so you don't know how to take screen shots or your apps aren't working?
usually when your apps don't work turn off your phone and turn it back on
that usually works
if you don't know how to take screen shots
press down both the home and power button at the same time
that should take a screen shot
