Specifically I think the issue is that if people drop the phone while reclined and then return the seat to the upright position to sit up to be able to reach down more easily, if the phone is in the wrong place it can get bent enough in the mechanism to compromise the battery pouch inside (which hopefully only makes it heat up and smoke but it can potentially catch fire, and fire is one of the the worst things to have in the cabin). This isn’t hypothetical, they put this in the safety talk since it has happened and obviously by reports like this, continues to happen!
