Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
There is nothing wrong with the S7 Edge. The issue of bursting into fire is with Note 7 not with S7 Edge. So if you have a S7 Edge, then you can safely use it.
The Galaxy Note 7 is the only Samsung phone that experienced widespread battery issues that lead to explosions and fires.
If you have any questions or would like any additional information, please don't hesitate to ask
