The smartphone industry is one of the fastest moving in the world at the moment. Only four months into 2015, already we've seen new handsets arrive from big names including Samsung, Sony, HTC and Asus on a near weekly basis.
What's more, with an LG launch event on the horizon and Apple expected to hold it's yearly iPhone launch in less than six months time, it doesn't look like the world of smartphones is going to get any slower.
To make sure any potential buyer doesn't get lost in the sea of announcements we've created a definitive top 10 list detailing the biggest confirmed and rumoured handsets to arrive this year.
The Xperia Z4
Sony surprised tech fans at MWC in March, choosing not to unveil its next flagship the Xperia Z4.
Instead the company chose to quietly unveil the handset one month later in its native Japan.
While there's no official word if the Xperia Z4 will arrive in the UK at the moment, considering its impressive specifications we certainly hope it will.
Featuring a similar IP-certified design to its predecessor, the Xperia Z3, the Xperia Z4 features a number of upgraded internal components.
Key features include a 5.2in, 1920×1080, 1080p LCD screen and impressive 20.7MP rear camera with Sony's back-illuminated stacked Exmor RS CMOS sensor for mobile and Optical Image Stabilisation technology.
Sony has also upgraded the Xperia Z4's front camera, loading the handset with a 5.1MP with Exmor R mobile sensor and wide-angle lens.
Given how impressive past Sony phone's cameras were, we can see the super-charged Xperia Z4 being one of the best camera phones to arrive this year.
Add to this its upgraded 2GHz, octa-core, 64-bit Qualcomm Snapdragon 810 processor and we can't help but get a little excited about the Xperia Z4.
