Six of the most anticipated smartphones of 2015 will soon be introduced, with three this March, one in May, one in July, and another one in September. Each is leveraging on their key strengths and bringing in a few yet excellent new features for better, faster, and longer-lasting smartphones.

This March Samsung and HTC are all set for the launching of each brand's flagship smartphone the Galaxy S6 and One M9 "Hima" respectively at the MWC in Berlin.

The Galaxy S6 will have a metallic body distinct from its predecessors and the first Samsung Android phone to come with the Snapdragon 810. Storage options now start at 32GB and camera megapixel might be either 16 Mp or 21 Mp shooter. Samsung is also hinting at a curved S6 variant which T-Mobile confirmed by posting a photo teaser on its website for the pre-registration.  

If Samsung is departing from the design of earlier models for this Samsung's product category, HTC is said to keep the stand-out design of the One M8 as well as the color options that is expected from HTC: gold, dark gray, and silver. It may also maintain M8's fast and efficient Sense software which proves to be an asset not all Android phones have. The only thing it needs to upgrade (and HTC has to take it seriously) is its UltraPixel camera. HTC will regain supporters and maybe attract new ones if it can do that.

Another flagship phone that is set for a mid-March launching is Nexus 6. Verizon posted a photo of the Nexus 6 complete with the carrier branding at the back of the device to inform its availability on Verizon Wireless very soon. Specs include a 5.96-inch Quad-HD display and storage options that start from 3GB of RAM, 32 or 64GB.

LG, on the other hand, will hold its own launching event for the LG G4 if predictions about the May release date is true. The LG G4 is projected to be powered by an in-house processor and be made available at slightly lower price than its rivals. It better provides improvement on the screen display which was the weakest area of the previous model. 

Xiaomi is also eyeing for a separate launching event for the Mi 5 which is quite understandable given its lack of presence in the US and Europe. Yet even so it manages to land on the third rank in the list of top selling smartphones for 2014.

The Mi 5 is crammed with the latest specs high-end phones boasts of at a price twice lower than rival phones in its category. This doesn't mean though that Xiaomi users can't demand for a more updated OS from the tech manufacturer. It is expected to be released in July.

Of course the list will not be complete without the world's top selling phone in 2014: Apple. Apple is expected to release the iPhone 6 and the iPhone 6 Plus mid-September. Tech reviewers are confident that it will keep the device's stand-out premium design and at the same time add a small further boost in iOS 8, an upgrade in the camera sensor, and a few more usual surprises from Apple.
