Why Samsung dropped microSD on the Galaxy S6, then brought it back

It wasn't up to scratch

The Samsung Galaxy S6 was a critical hit for the South Korean brand, but dropped one of the big things that fans loved: the microSD slot.

Its return on the Galaxy S7 has been lauded as a boost for the new phone, but why did it disappear in the first place when so many other brands, like LG, Sony and HTC, managed to keep it as a key part of their flagship phones?

"At the time we launched the S6, we upgraded all the performance within the device. We upgraded to UFS 2.0, we upgraded to DDR4 RAM… we believed that having a memory card slot would slow down the performance of the device," said Kyle Brown, head of technology, content and launch management at Samsung.

"Thankfully on the S7 we've managed to get the best of both worlds."

The brand launched the S6 with multiple options of internal storage capacity, but that forced the price of the phone up dramatically if you fancied the 128GB Galaxy S6, with many commenters claiming that Samsung was just trying to ape Apple in the way it sold phones.

However, Brown said that it was merely a performance decision, although he didn't comment on why other brands were able to make the technology work, stating that Samsung 'weighed up the pros and cons' of what to include in the device and wanted to make sure design, along with performance, was brought to the fore.

"A lot of people were very disappointed we didn't have a [memory card] slot in the S6, and [its return] has been one of the most positive reactions to the S7. We're really proud of what managed to achieve, adding a microSD slot and water resistive IP68 rating. It's a really massive achievement for engineers."
