One of the most welcomed features of the new Samsung Galaxy S7 and Samsung Galaxy S7 Edge is the microSD slot even if Google’s adoptable storage is not available. Being able to add additional memory suited to an individual user’s needs has been a big selling point for Android devices compared to iOS devices and joins a removable battery as one of two features invoking strong feelings in potential buyers. When Samsung released the Galaxy S6 last year, they were roundly criticized for dropping both of these items. This year Samsung brought back the microSD slot and now they are openly discussing their reason for the one year hiatus of the feature in their flagship line.
Samsung’s Kyle Brown, who heads up technology, content and launch management for the manufacturer, says the key factor in the company’s decision regarding microSD cards was performance,
“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.”
The explanation may not satisfy everyone though. Some people have noted that other manufacturers like LG, HTC and Sony were able to successfully include microSD card slots in their devices that used similar, if not the same, hardware. Also unclear is what Samsung may have done to address any possible performance issues during the intervening year.
