The Huawei phone is probably the more unusual of the two, since it appears to be one of the first phones to sport 3 cameras on the back instead of two. It looks like they’ll be vertically stacked and also work with an LED flash and laser autofocus.
It’s unclear what the extra camera is for, but given what we know about dual-camera systems, enhanced telephoto, wide-angle, or adjustable depth features seem like a safe bet. Or maybe you’ll be able to choose between different lenses depending on the situation.

Asus, meanwhile, seems to be intent on releasing a new flagship phone with a 18:9 (2:1) aspect ratio display, dual rear cameras, a fingerprint sensor on the back of the phone, and a micro USB port, at least according to some leaked images.
We’ll have to wait a little longer for official specs, release dates, and pricing.
Asus has scheduled a Zenfone 5 announcement for February 27 in Barcelona, and the way the company usually does things makes us think it won't be just one Zenfone 5. If anything, the #backto5 tagline could be closer to the number of devices we may see at MWC, in addition to being a shout out to the already existing Zenfone 5s. Just Asus things.

Anyway, one of these Zenfone 5s has been revealed in a manufacturer's manual sporting an (aluminum?) unibody and a tall 18:9 display, likely in the 5.7" ballpark. Carrying an internal designation X00PD, it's unclear which model exactly this would be. Judging by the microUSB port, however, it's looking like a non-flagship device.
Even so, a dual camera on the back suggests it's not a low-end phone either. Asus has made phones with a pair of shooters on the back before; however, starting with this generation, the two sensors are arranged vertically, instead of side by side.
That's just a teaser, though - there's about three weeks until we see the real deal.
Asus has confirmed that it is announcing its ZenFone 5 series at the upcoming Mobile World Congress 2018 (MWC 2018) to be held in Barcelona from February 26 to March 1 but what we still don't know is its key specifications. Now, several pictures of the purported handset have been leaked ahead of its launch, revealing its design details.
The Taiwanese company has announced in a tweet that it is unveiling its ZenFone 5 series. The press event will be kick off at 7:30pm CET on February 27 (12am IST, February 28) and it will be live streamed on the firm's official website.
The handset from the ZenFone 5 series is seen from all possible angles in pictures shared on WinFuture website. It is obvious from the photos that the device will sport a 5.7-inch display with 18:9 aspect ratio. It is also seen with microUSB port, speaker and mic at the bottom, and the 3.5mm audio jack seen in its predecessors, including the ZenFone 4.
It was earlier reported that the ZenFone 5 series to be unveiled at the MWC 2018 could be called ZenFone 5 Lite and ZenFone 5 Max.
The ZenFone 5 Lite has reportedly received certification in Russian, thus paving the way for its launch, according to Mobiltelefon (in Russian). It is also reported that the ZenFone 5 Max with model code ASUS_X00QD has received Wi-Fi Alliance certification. Both the handsets are expected to run on Google's latest operating system Android 8.0 Oreo.
