Corrected entry: During Isaac's death in the massage parlor, after his phone rings during the acupuncture scene the elderly woman takes his phone and puts it on the edge of the shelf near a candle, however in the next shot the phone is not on the edge of the shelf but further into the shelf and right next to the candle.

Correction: It's not the next shot. And the reason it moves towards the candle is because it's on vibrate which makes it move.
