Motorola, a subsidiary of Lenovo, plans to sell a retractable phone next summer, according to a person familiar with the company's plans, according to the technology website CNN.

The website said the design would not be the same as the Samsung Galaxy revealed a few days ago, or the Huawei Mite X phone, which was presented at the World Mobile Congress in Barcelona last Sunday.

The device is likely to revive the Razr brand, which the Wall Street Journal said would return at $ 1,500. The website "Engadget" on technical issues on Wednesday confirmed the launch of such a phone.

The summer launch date will put it directly in the launch date of the Galaxy Express scheduled for April 26 and the launch date of the MiteX mid-year, and will highlight the growing trend of folding phones.

The Samsung and Huawei phones generated a lot of hype and became the focus of talk at the global mobile conference, at a time when interest in smart phones is beginning to decline.

Unlike my Galaxy and Mite X, which open like a book to a large-screen tablet, the Razr design, based on patented designs discovered by 91 Mobile's code, turns into a smaller device like the original Razr .

This design has some advantages, including protecting the screen as soon as it is folded. If it simulates the original phone, it will also be much smaller than Samsung and Huawei.

The original Razr was one of the most famous brands, and helped drive Motorola's success for years during the Golden Age of the flip-flop. It was one of the most successful handsets in history according to CNN, where it sold more than 50 million units in its first two years.

But Motorola was unable to take advantage of the success of the "Razr" and fell with the transition of the industry to more complex phones. Google bought the company in 2012, then sold it two years later to Lenovo.

Now, Lenovo has an opportunity to re-energize the Motorola brand with the Razr phone again.
