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.
