I searched but didn't find anything similar. Has anyone had problems with airplane mode? Late at night and sometimes during the day, my phone will put itself in airplane mode. I cannot send or receive calls and using the Touchwiz panel to turn on and off the mode does not work. I have restarted the phone a few times and sometimes that does the trick. The strange part is that there is no airplane mode icon. When I try to make a call, it says to turn airplane mode off and I am re-directed to the settings page to do so. When I un-check airplane mode, it doesn't help. When I go back to the settings page, airplane mode is re-checked. I find that the battery drains really fast in this state. Has anyone experienced this? Pic for reference.
