Samsung will be giving us an official answer as to why the Samsung Galaxy Note 7 was exploding. We were supposed to wait until the 23rd of January to get our answer but it looks like be might already have some leaked answers right now.
It has been reported that the real issue with the Samsung Galaxy Note 7 was that the device designed to have too little tolerances. They did not give the battery enough space to expand.
On top of that, the software which was supposed to shut the device off when it detects a thermal runaway failed to work. It is also said that Samsung tried to fit in too many features like the iris scanner and S-Pen. In the end, the battery just could not cool down fast enough.
We will still have to wait until the 23rd of January to see if that is what Samsung will be saying officially so take this with a pinch of salt.
