Hi, I have got a HTC desire S, with android 2.3.5. Since some days, it's impossible to access to the "Stop/Reboot/Plane mode" menu, pressing power button for some seconds. When I press the power button, my device goes to sleep mode, even if I press power button for 2, 3, 10 seconds... I think it is since my update to 2.3.5, but I'm not sure... Do you have an idea about that? Thank's in advance.
