Whenever i lock my iPhone while connected to our wifi the connection drops and none of my notifications come through until I unlock my phone so it is hard to know who is messaging me on Facebook or who is skyping me ect
I am leaning towards this being a phone issue as I honestly have never experienced this before and I'm an Apple user. If you ensure your iPhone is backed up, it might be worth resetting your phone and set it up from scratch again.
