Now the South Korean electronics giant has stabilized the ship and "got its mojo back," according to analysts.
On Thursday, Samsung reported operating profit of 6.68 trillion won ($5.8 billion) in the first quarter of 2016, a nearly 12 percent rise from the 5.98 trillion won recorded in the same period last year.
In the mobile segment, operating profit hit 3.89 trillion won, up 42 percent year-on-year, and was the biggest profit driver for the company for the first time since the second quarter of 2014, according to Reuters.
Behind the strength of the business was Samsung's Galaxy S7 and S7 Edge smartphones which helped lift profits.
"Samsung has had a real return to form with the S7 and S7 edge. It's focus on higher-tier, higher-margin products has certainly helped boost its earning. The new devices deliver a good story for anyone considering a Samsung device as an alternative to an iPhone," Ben Wood, chief of research at CCS Insight, told CNBC by email.
"Samsung certainly seems to have got its mojo back in mobile devices."
