Has anyone experienced some strange signal strength issues on iPhone 5 running Beta 4? It seems to me like the algorithym for how signal strength is displayed is all messed up. Places in my house that used to have just 1 or 2 bars of signal strength now have full signal according to beta 4 but next to no reception regardless. Also, there are times where ill be connected to LTE and then loose signal and get stuck on 4G. The only fix is rebooting the phone or resetting the network settings. Anyone else getting these issues?
