Screen flicker on newer iOS device when launching game

Hi All

We are working on a 3D graphics iOS game (using the Binary build of UE 4.10 on Windows 10 machines) and having some really bizarre issues when trying to launch it on newer iOS devices (specifically on occurred on and ). We’ve been developing the game for the last couple of months and testing it on an and along the way with none of these issues.

Basically what happens is we launch the game from the UE4 editor and it “pushes” to the iOS device with no issue. Then when you try and actually tap on the game icon the device the screen RAPIDLY flickers between a white screen and your home screen (the game does not actually launch). The device becomes completely unresponsive and the only way to stop this is to do a hard reset (hold home and power button for a couple of seconds).

We’ve only seen this happening on “newer” iOS devices ( & ). The exact same build runs perfectly on an and .

All iOS devices are running the latest iOS 9.2.1.

Any thoughts on why this might be happening?

I think this flickers only occur on and iPhone 6s/6s Plus, and I think it got something to do with the metal settings. Try untick that if you have it ticked.

But perhaps I’m wrong. Try check on AnswearHub. I have iPhone 6 Plus and it does not give the flicker.

Hi. I have same ploblem.
