iPhone X weak cell signal

I received my iPhone X on Friday and have set it up. While it's a fantastic phone overall, the cell reception *****. On my previous iPhones (4, 5s, & 6s) I had no problems in my apartment and could use the phone in any room. Not the case with iPhone X. I have no reception anywhere unless I'm sitting in the window where I get a single bar. This is absurd for the supposed most advanced cell phone. Is there a setting that can be changed to boost reception? I live in downtown San Francisco where cell coverage should be abundant. Any fixes would be appreciated.

iPhone X, iOS 11.1

I'm having the same problem. I took my new iPhone X to the genius bar and all they did was run a diagnostic on the phone and tell me that there was no hardware issue, so it must be a carrier issue. Luckily, I was able to return the phone because I was within 14 days of purchasing it at the Apple store. I then bought a new iPhone X, and three days later, and it's having the same weak signal problem. It almost always goes to 4G in places where I previously had LTE, and it has one bar in places where I previously got two to three bars. My kids and my husband all have iPhone 6 models, and we can all be in the same location together where they get bars and LTE, and I get nothing with my $1149 phone. Therefore, I'm returning the X and going back to my older iPhone 6 Plus, and I'm seriously looking at the Samsung Note 8. For over a thousand dollars, I expect the phone to work!

I took mine back to the Apple store too, where their diagnostics showed that the iPhone X in a few days had dropped four out of thirty calls that they acknowledged were the fault of the phone. Then they told me that that was below their 20% threshold and they would not normally consider it a serious problem! Pretty incredible!


Their diagnostics do not track failed call attempts... my phone had failed at least ten times to make calls in areas where I have routinely made them in the past.


In the end, they agreed to replace the X with another one, same model. The new one they gave me is no better. I'm considering also returning mine and going back to my iPhone 6s Plus which has been a great phone.

I've just discovered the same thing.


My wife and I were sitting across from each other in a coffee shop yesterday. She had a three-bar signal on her iPhone 6, I had a one-bar signal on my iPhone X. Over twenty minutes and a half-dozen attempts the problem remained and attempts to access web sites failed with can't connect, not online errors. During that time I turned off and turned on the phone; no change. Meanwhile my wife was surfing happily the whole time. At our home location an hour later we both had three bars.


My previous phone was a 6s Plus and the small handful of times we compared cell signals they were at the same level.
