S7 Edge fires
A low single digit number of reports for something that has been out for a while and probably has 10 million plus phones in the field is not indicative of a serious systemic flaw like the Note 7 suffered from. The Note 7 was burning up at a rate probably 1000x greater based on how few it had sold and how short of a time it had been around.
If you recalled every model of phone that ever caught on fire even once, we would all be switching phones every few months - unless you bought some wildly unsuccessful model that only sold 10,000 worldwide (i.e. rely on statistics to keep your model "safe")
