This is a little off topic, but it's been driving me nuts and I want to know if anyone else has experienced this. I feel like iOS 11 causes my phone to drop calls... I have an iphone 5s, and took a loooong time before I updated to iOS 11 from iOS 10.3. I learned the hard way with my iphone 4 not to blindly click update or your phone may be unusable. Anyway, I have been in my apartment since the beginning of the year. I make all sorts of phone calls no problem. Reception is good, usually 3-4 bars. In June I updated my phone to iOS 11. Since then, a phone call in my apartment will last at best 5 minutes before I get a "Call Failed" screen. It's insane. I look at my phone and it has 4 bars. Literally as I press the "Dial" button, it instantly drops to 1-2 bars. Usually about a minute into the call it drops to 0 bars. Then the call drops. As soon as the "Call Failed" screen goes away, it's back up to 4 bars. I feel like I'm going crazy. Has anyone else experienced this? I haven't been able to find any similar bug reports or experiences online... edit: i meant iOS 11. I am hesitant to update to iOS 12 because of my experience with 11

This sounds like you're getting data on LTE, but you don't have VoLTE (not available on iPhone 5s? or not provisioned by your carrier for you). As a result, when you use calling features, your phone will drop LTE and connect on an earlier standard to make calls. Carriers have been reallocating spectrum from older standards to LTE, so it's not unlikely that carrier changes reduced your calling ability around the same time as you made software changes to your phone. Double check if VoLTE is available for your phone, and try to get that enabled... Or stand closer to the window when you make calls.

  Huh I never thought of that (or even knew about VoLTE). I'll look more into that. I am always hesitant to say "it was definitely such and such upgrade" but I can't think of anything else that changed about my phone in mid June except my iOS update. It took me a month or so to realize that it was a persistent pattern, so it's not like I updated on Monday and on Tuesday realized my calls were dropping.
