WebRTC remote video keeps freezing on ios Safari


We have a WebRTC based solution and have been excited about WebRTC support on ios 11 Safari. However, every WebRTC solution we have tested using iPhone 6 on ios 11.0.3 experiences the same problem:

After a while the remote video freezes and the whole phone crashes requiring force reset. There seems to be no talk about such issues anywhere on Internet. Has somebody been experiencing the same and have you found any solutions?

We have replicated the issue with ios 11.0.2, ios 11.0.3, iPhone 6 iPhone 6+ and the following solutions:

  • Our own WebRTC solution based on SimpleWebRTC
  • Talky.io
  • TokBox Safari Demo
