Huawei said its foldable phone will launch in September, slightly later than it was reportedly set to, as it does extra tests following the debacle Samsung went through with its rival device.

A spokesperson for the Chinese technology giant told CNBC on Friday that the company is trying to launch the Huawei Mate X globally, focusing on markets that are rolling out next-generation mobile networks known as 5G. The Mate X, which starts at around 2,299 euros or roughly $2,600, is a 5G-capable device.

The Mate X was unveiled in February but has yet to go on sale. Huawei had initially targeted a mid-2019 launch date and in April, Chinese media reported that it was looking at June. But the spokesperson confirmed the official launch will take place in September. He said that the company was doing extra testing with mobile carriers around the world and developers to make sure their apps work when the device is fully unfolded.

Huawei’s spokesperson said the company was more “cautious” after Samsung’s foldable device, the Galaxy Fold, began to break when tested by reviewers in April. Samsung and some of the carriers selling the Galaxy Fold have canceled pre-orders that consumers had already placed.
