Apple iPhone 7 and 7 Plus
Expected this fall, there's not much we officially know about Apple's next flagships. Because this is an even-numbered year, however, we do anticipate more changes to the design. Other rumors include the next A10 processor inside and a lack of a 3.5mm headphone jack.
HTC One M10
Though HTC's marquee series includes some of the best looking Android phones around, there's still lots of room to improve. For instance, a spruced up design that differentiates it from its predecessors would be great, as well as a better camera and longer battery life.
Microsoft Surface phone
With the critical success of the Surface Pro 3 tablet (pictured on the left), a high-end Microsoft Surface phone (that's not a Lumia) could be in development. And similar to the tablet, the device could come with a stylus and emphasize handwriting recognition.
LG G5
LG has confirmed that it will launch its next flagship handset at MWC 2016, but we don't know much else besides that. There has been some speculation that it'll have a pull-out battery and a fingerprint sensor like LG's other high-end V10 handset, but the former feature doesn't seem too likely.
The next pair of Google Nexus handsets
Last year, Google released two flagships: the Nexus 5X and the bigger and pricier 6P, both of which featured a fingerprint sensor and USB Type-C. The next successors should come some time in October and will hopefully add two more devices to Google's Project Fi Wi-Fi only service.
The OnePlus 3
OnePlus, a scrappy mobile manufacturer, drew consumers in with a high-end but incredibly inexpensive smartphone. And while it recently started selling the even cheaper mid-tier OnePlus X last month, the new year should mark a third generation for its flagship line.
Lenovo and Google's Project Tango
Project Tango, a program that will bring motion tracking and depth perception to mobile devices, has been in the works for a long time. But at CES 2016, Google and Lenovo announced they are teaming up to finally offer a Project Tango phone (a tablet is already available for developers). It'll go on sale by the summer for less than $500 (about £350 and AU$720) and use three cameras to virtually map out the space around it.
A high-end Windows 10 Mobile phone from Alcatel
At CES, Alcatel showed off its first Windows 10 Mobile handset, the OneTouch Fierce XL (left) -- but the company doesn't intend to stop there. In fact, Alcatel's senior vice president of the North America region, Steve Cistulli, says the company will make a "superphone" that runs the Microsoft mobile OS and will be on par with high-end devices from Apple and Samsung.
Nextbit Robin
Created by ex-Google and HTC execs, the Robin started off on Kickstarter last year and will be available this February for shipping. Aside from its quirky design, the phone will work on networks using both GSM and CDMA technology, feature a 5.2-inch display and have 100GB of cloud storage.
Yezz Sfera
The Sfera by Miami-based mobile manufacturer Yezz looks weird and clunky, but that's because it has a 360-degree camera on its top bezel. That means the photos you capture and videos you record can be viewed in an immersive VR headset. Sure, that's a pretty niche thing to sport, but it's enough to make us really curious.
