I’m running the Wyzecam app on an iPhone SE, which happens to have the same display size as a 5S. I noticed in at least two places in the app, certain elements of the user interface/controls are overlapping. I’ve attached screenshots.
I have seen the same problem on my @#$%^&* iPhone 6S
Looks like the second overlap I posted is fixed with the latest update. The first one still exists though.
