Even the replacements are catching fire. All of the major carriers in the US have issued press releases that say they are halting Note 7 replacements and offering exchanges for the phones regardless of purchase date. A lithium ion battery if it goes into thermal runaway burns extremely hot. This places the Note 7 users in high danger. If you have a Note 7 return it to your carrier immediately.
For me I would also not trust the s7 as it is basically the same as the Note 7. While there are no reports of the S7 catching fire I would be wary of these phones as well.
