The much-anticipated HTC M7 is widely believed to be a hopeful new flagship handset from the currently ailing tech giant. Due to preview at the Mobile World Congress in Barcelona this February, it’s purported to boast a 4.7-inch display, 13-megapixel camera and the new HTC Sense 5.0 software.

2. Apple iPhone

Apple has been characteristically cagey about information regarding the new iPhone, but early reports seem to suggest the team is aiming for a summer release date. Online speculation is laying expectations for higher resolution displays, HFC capability and the long-awaited wireless charging.

3. Sony Xperia Z

Originally expected at this month’s CES, the Galaxy S4 is now pegged for a May release. Notable rumours include the update to a five-inch screen, a 13-megapixel camera on the back and 2-megapixel front-facing lens, and perhaps most bizarrely a flexible, foldable display.
