I’m also having the exact same issue and actually I’ve read about a dozen other threads with people having the exact same issue. It truly seems like a persistent problem on many iPhone X devices and I’m surprised apple STILL has yet to come to a solution what with so many people having this recurring issue. Whenever I press the side button, the first initial press doesn’t wake the screen. The second press then wakes the screen but immediately activates apple pay. SO THE FIRST PRESS WAS REGISTERED, the screen just didn’t wake. I have done everything apple suggested to do, with no solution. It is most certainly a software fault. This should be addressed and I don’t know why it isn’t. I’ve had this phone for months now. It’s not a huge problem, but it is becoming increasingly more persistent and that much more annoying. Before anyone replies with what they think is a solution please read the entire comment. I’ve repeated myself to 10’s of people with the same responses and suggestions. Which is restarting the device, restoring the device, and then doing a complete wipe. None of these suggestions worked the phone still has the same exact issue gradually getting worse. Also the button works entirely fine, because it sleeps the screen on EVERY press. And registers the first intial wake press but just doesn’t respond until the second press activating apple pay. Again IT REGISTERED THE FIRST PRESS. In case anyone missed it. I would just love a solution that actually works, because the phone is great, but this issue is just really annoying.
