Eventually, Samsung released two updates for the Note 7, one that activated a 60% charge limit and then a 0% charge limit that made the phone unusable even though the charge limit can be removed by erasing the phone and downgrading it to Version 1, the stock release. Initial reports On 31 August 2016, it was reported that Samsung was delaying shipments of the Galaxy Note 7 in some regions in order to perform "additional tests being conducted for product quality"; this came alongside user reports of batteries exploding while charging.
