I spoke to apple support on the “apple support” application from the App Store and they ran a diagnostic test remotely on the phone. They were able to see the dropped called, which were about 30% of calls at the time.
When I went to the apple store, annoyingly they decided to do all the diagnostics tests again. But that time they say how much more bad it was. Of 130 calls , about 60 had dropped. (I guess a more advanced diagnostic?)
Nonetheless, they replaced it after I had done basic troubleshooting with tech support prior. Such as restore the phone to factory settings using a computer (fresh install), contact the carrier to do troubleshooting on their end etc.
I’m surprised I’d get two duds in a row. The other baffling part is how “not widespread” this issue it. So it’s definitely affecting a smaller pocket of people like you and I and meow mixes friend.
At the apple store they said mine was the first they saw with the issue.
You should've showed them the 122 page thread on Macrumors, this issue is very wide spread and affecting all carriers. I personally wanted to get the XS Max, however this issue of poor connectivity is what has stopped me.
Cellular connectivity is my number 1 priority in a phone, so I may jump ship and get a Pixel 3 since it uses Qualcomm.
I currently have a 8 Plus with the Intel modem, and I find the phone switches to 3G a lot, instead of hanging onto LTE like my old Qualcomm iPhone 6s did in the same locations. The 1 bar of LTE provided better speeds/experience than the 3-4 bars of 3G in the same location.
