On 31 August 2016, it was reported that Samsung was delaying shipments of the Galaxy Note 7 in some regions to perform "additional tests being conducted for product quality"; this came alongside user reports of batteries exploding while charging. On 2 September, Samsung suspended sales of the Note 7 and announced a worldwide "product exchange program"[31] in which customers would be able to exchange their Note 7 for another Note 7, a Galaxy S7, or an S7 Edge (the price difference being refunded).
