The s7 edge doesnt have a history of overheating. It appeared her phone specifically did. It's unfortunate and I'm glad no one was injured. The truth is since the note 7 recall, news outlets across the world report on every Samsung phone fire. Considering Samsung sells more phones then everyone else there will probably be more incidents of its phones catching fire. Also Considering the amount of phones sold the percentage is so low its almost negligible even when you included the note 7 fires. The fact that it is a fire that we're talking about, even 1 incident is enough for concern but the truth is all cell phone brands have these incidents about the same percentage as any Samsung phone. Case and point below.

But I bet you never heard about this incident and there are many many more, just google iPhone fire, or htc fire, or lg fire etc... the reason Samsung phones and tablet fires are in the limelight is because Samsung did a recall and everyone is aware and news outlets capitalize on continuing to feed the monster.
