Hello there Laser54321,
Thank you for using Apple Support Communities!
It sounds like you would like to disable the screen rotation lock.
iPhone User Guide
I have a similar problem but swiping up and disabling the rotation lock sign is not helping and under General-> i cant find lock rotation, am i blind or what? srsly its not there, nada, nothing
it just wont turn
I wanted to use the sideswitch to lock or unlock the sideswitch but there is no place called lock rotation in general....
using ios 8.1
bought the iphone 5 used, but everything else works fine
Got an ipad mini and it works totaly fine...
I have the feeling I am blind....
