I have a clock app that shows time and weather.
- When app launches I show clockViewController. If a user clicks on the the cloud looking button on it then I take them to weatherViewController
- On weatherViewController I present 4 day weather forecast and if they click on the arrow button it takes them back to clockViewController.
- I created both these buttons through drag and drop storyboard and added a Triggered Segues connection between the two view controllers. Pretty straight forward
- Everything works as expected and designed. (see these screenshots)

Now here's the weird part, yesterday I got an email from a user saying this word to word "It takes 2-3minutes and them it switches to weather and then after some period back and then weather and it stays on weather . It works perfect on my 4S but always with bug on 5S?"
How could this possibly happen? I thought about it being a hardware screen bug but how can it press buttons that are not laid out in the same pixel area on the screen?
I don't own a iPhone 5S so I cannot test that on a real device. I did however ran it in simulator (4-in 64 bit, Xcode 5, iOS 7) and for 30 minutes it remained on the clock page.
I kept telling this user that there is no way it could change on its own without someone actually touching the buttons but they keep insisting there is a bug in our software. Is this a problem with their hardware? Should they take their phone to Apple store? I am out of ideas ... short of telling them their is a ghost in their house that likes apple devices.
