Samsung hopes to reverse its fortunes with a radically redesigned flagship smartphone.
The company on Thursday said that itssmartphone, alongside its curvy sibling, the , will go on preorder Friday and then become available for purchase at carrier and retail stores on April 10 -- the same day that and that Apple begins taking preorders for its Apple Watch.
Samsung's latest smartphones incorporate aluminum and glass, higher-quality materials that set them apart from previous Samsung phones, which largely used a plastic shell. But the change did come with sacrifices -- the company ditched the microSD slot for expandable memory, as well as the removable battery.

A lot is riding on Samsung's Galaxy S6 line. The company saw its smartphone market share and profits slide last year after the tepid reaction to its predecessor flagship product, the Galaxy S5. But with a new design and a focus on premium materials,and stay atop the smartphone mountain.
"The Galaxy S6 represents a new era of design for us," Hong Yeo, the senior designer in charge of Samsung's new devices, said in an interview at the time of the phones' unveiling earlier this month.
Samsung's phones are going up against some formidable competition. Apple's iPhone 6 and 6 Plus, launched last September, sold like gangbusters in the fourth quarter of 2014, helping propel Apple to world-record profits. That surge alsoin global market share in the fourth quarter, with each company claiming 20 percent of the market -- but it was Apple edging up while Samsung plunged from 30 percent a year earlier.
On the lower end, meanwhile, Samsung has been contending with up-and-comers like China's Xiaomi and India's Micromax.
