Nope. You'll recall Paul couldn't explain how his phone ended up under his body him given the CW's scenario. Because it makes no sense.
His phone was likely turned off at some point by one of the perps in the house, and then turned back on when they dumped it on the lawn.
Recall also that his health app time stamp - stairs or no stairs, steps or no steps - had movement up until 12:31.
It is undisputed that Karen was gone by then as she was at One Meadows at 12:36 and she couldn't have beamed there.
