Samsung unveiled its latest gadgets this week at the consumer electronics show in Las Vegas.
But it seems to have joined Apple in the ranks of troubled tech giants.
On Tuesday (January 8) it warned profits would be down almost 30 percent in the latest quarter.
The Korean giant says a slide in demand for chips is to blame.
It also warned that profits would remain weak in the coming months.
New smartphones due to be released in the second half of 2019 are its earliest hope for an upturn.
Samsung is the world's biggest maker of smartphones and semiconductors.
The drop in profits comes a week after Apple made the rare move of cutting its earnings forecasts.
And the two stories are likely related.
Samsung is a big supplier to its U.S. rival.
Now both firms face similar challenges.
Demand in China - the biggest market for smartphones - shows signs of going soft.
Competition from Chinese brands including Huawei is also on the rise.
Then there's concern over the impact of the U.S.-China trade war.
It's all a negative for investors.
Samsung shares down by almost a quarter last year.
On Tuesday the stock was down a fresh 1.7 percent.
