The Samsung Galaxy S6 and S6 Edge were not free from mistakes such as its lack of an SD card slot and its smaller battery capacity.

However, the device’s biggest failure stems from poor planning from the manufacturer. Samsung had wrongly estimated the demand of the S6 Edge model which led to a mass shortage resulting in lots of missed sales.

But this mistake is nothing compared to the Galaxy Note 7. Users had experienced their Note 7 catching on fire or even exploding which made Samsung recall all of its Note 7 units worldwide.

This poor quality control had affected Samsung so bad that the South Korean company saw a $7 billion loss in their market value.

That’s not all – the company had revealed recently that the whole sales discontinuation and recall exercise would amount to about $1 billion. On top of that, a Samsung Securities analyst has said that the total loss due to the Note 7 episode as well its remedial efforts would total up to an estimated $740 million.

Now, that is quite a big blow to Samsung!
