What Will I Lose?
Can an iPhone show two apps side by side?
Not with a built-in, general-purpose split-screen mode for two arbitrary apps. On iPhone, supported videos and FaceTime can use Picture in Picture while you use another app. Apple's windowed multitasking features are documented for iPad.
What to do
- For video multitasking, open a supported video or FaceTime session.
- Use the Picture in Picture control to minimize the video.
- Open another app while the video floats on screen.
Limits and compatibility notes
Check this before relying on the answer
Picture in Picture is not the same as running two full apps side by side. App support varies; check the controls on your current iOS version.
