Has anyone else found recently that the iPhone “signal breathes” a lot more than it used to. My home has a good coverage of 3 bars but often sat in the same place it will go down to 1 bar without me doing anything and then about 5 to 10 secs later go back up to 3 bars. This never used to happen but happens often. Because it’s happened recently I’m wondering if a software update has screwed things up.
