Both Samsung and Huawei said their devices can withstand the wear-and-tear of over 100,000 folds.
Apart from being foldable, the Huawei Mate X is also 5G-ready thanks to the company's Balong 5000 modem, and it fueled by the Kirin 980. The phone has a dual SIM tray that can take two nano SIM cards or one nano SIM and one NM card.
Rory Cellan-Jones, the BBC's technology correspondent said, "Security concerns about Huawei's 5G kit are a shadow hanging over the whole of this year's Mobile World Congress".More news: Lawyer: Ex-FBI official McCabe still facing investigation

In the photography department, it comes equipped with a Leica-branded triple-camera configuration that comprises a 40-megapixel wide angle lens, 16-megapixel ultra-wide angle lens, and 8-megapixel telephoto lens. The Galaxy Fold folds (duh.) easily into a compact form factor that snugly fits into a coat pocket. Android 9 is installed with EMUI 9.1.1.
Phone manufacturers have been gearing up for the 5G era, and Huawei is among them.
The Mate X's insides are equally as impressive. When folded, the rear screen can be used for selfies and showing others what they look like when you're photographing them, which is kinda neat. Emphasis on "seems", though. By nature of it being a flexible display means that we're dealing with a polymer material which is softer than glass, and thus also more scratch prone. After all, glass can't exactly fold. And the exterior 4.6-inch display looks kind of ridiculous from the outside, with its obscenely large bezels and downsized UI elements to fit everything in that tiny space.
The phone will have a very steep price at Dollars 2,600 but it is hard to say that it is too expensive.
This is a dramatically different approach to the Galaxy Fold, which keeps its pliable screen on the inside of the device in order to protect it from scuffs and scratches.
