From launch until yesterday, my Max has been running circles around my iphone 6s plus and Qualcomm X, even in weak signal areas. Yesterday, it acted like it had hit a brick wall and couldn't come close to the speeds of my iphone 6s plus (only other phone I have left to test with). First time it has had the symptoms everyone on here has been talking about. When I say slow, I'm talking less than a meg, while the 6s plus was hitting about 10 megs. Today, everything is back to normal and the max is crushing the 6s plus. Only difference I can see, is yesterday was a cloudy day, and today it is clear one. Sometimes weather can affect reception, but I don't know if that was the problem or something else. I really hope it wasn't the weather, because that starts to point toward the antennae as the problem. I hope to keep this very expensive phone for a few years, but not if it's going to have receptions problems. Fingers crossed for a software fix.
