Red Border on Screen
Hi guys,
I just bought a new Bluetooth wireless keyboard and mouse for my iPad. They seem to be working well, but I noticed that sometimes a red border appears on my screen ever since I started using them. Sometimes it’s surrounding the whole screen, but sometimes it surrounds a specific area, like a sidebar. I’m assuming this is meant to happen and that it is not any sort of bug, but could anybody please explain to me what it is and how I can prevent it coming on my screen?
Thanks.
