Samsung invited the wrath of its fans last year by releasing the Galaxy S6 and Galaxy S6 edge without two simple yet important features seen in its predecessor. Samsung is likely to bring those features back to the upcoming Galaxy S7 and Galaxy S7 edge.

The South Korean electronics giant will offer microSD card slot expandable up to 200GB and IP67 certificate (dust and water resistance) in the Galaxy S7 and Galaxy S7 edge devices, reported VentureBeat, citing a source with knowledge of the company's plans. 

Interestingly, these features – microSD card slot and IP67 certificate – were seen in the Galaxy S5, which was released in 2014, but were discarded in its successor. This move left many Samsung fans disappointed. Now the company seems to have learnt a lesson.

The Galaxy S7 and Galaxy S7 edge are expected to be unveiled at the upcoming Mobile World Congress 2016 (MWC 2016) in Barcelona, Spain. Samsung has now hinted the same by releasing a teaser video stating that its next Galaxy device will be announced at its "Unpacked" event scheduled on 21 February.

Leakster Evan Blass â€@evleaks has claimed that the Galaxy S7 and Galaxy S7 edge will be released in the US on 11 March, but it's not confirmed yet. The devices have also been spotted on Zauba, a website that tracks imports to and exports from India, sent from Korea for testing purposes. 

Samsung hasn't revealed any detail about its upcoming devices but reports have claimed that the Galaxy S7 will sport a 5.1-inch QHD display with 2,560x1,440 pixels, and the Galaxy S7 edge will come with a 5.5-inch screen. However, the devices are expected to share same specifications.

The devices are expected to have features like Exynos 8890 or Qualcomm Snapdragon 820 processor (depending on region), Android 6.0 Marshmallow, a 64GB inbuilt memory, a 4GB RAM, a 12MP main camera and a 5MP secondary snapper.
