I have an X on tmobile and it's abjectly terrible. I had a 6S+ before it. In the same location, on the same network, it will drop signal or become unusable and gets lower reception almost everywhere.

This is nearly as bad as the issues reported with the essential phone, honestly. It's a night and day difference you can compare side by side if you have two devices.

With good signal it's fine, and the speeds are plenty fast. I have no complaints about battery life. It's entirely when the signal is marginal that it's garbage.

I've considered selling it and buying the verizon or unlocked qualcomm model multiple times.
