I have almost exactly the same problem as well: If I have my phone off for more than a few minutes, the screen is mostly unresponsive unless I sleep and wake. It will respond to some touches but not most, and it’s bad enough that I can’t even swipe to unlock. I have not replaced the screen on my phone. Rather this issue started randomly one morning after sleeping on it. My headphone was pressing into the screen. A hard reboot didn’t fix anything. I also thought it might be something to do with capacitance, like sleeping and waking was discharging something. However I bet it is a faulty connection corrupting some controller, and sleeping resets it. If opening it up and wiggling around the connection works, I’ll post here.

Yes, hooking the top part of the phone in first seems to be pretty important. Also the plastic rim had broken and detached, which made pressing the screen back in even harder. Laying the phone face down to press the screen back in that way probably saved me from breaking it. Major upvote on this comment.
