This year has been one of the most interesting to date for smartphone buyers. While Apple and Samsung have continued to dominate the mainstream headlines, competing firms have shown they aren't willing to throw in the towel, and have challenged the duopoly by releasing some of their most advanced handsets to date.
Korean firm LG has been one of the most successful in this endeavour with its G3 flagship. Released in June, the G3 is in many people's minds, including ours at V3, one of the most innovative handsets ever made. In fact, it's so good that many buyers will wonder how it compares with Samsung's Galaxy S5 and Apple's iPhone 6.
Design and build
Visually all three devices are fairly distinctive. The G3 is by far the biggest and comes close to breaking into phablet territory, measuring 146x75x8.9mm and weighing 149g.
The iPhone 6, despite being notably bigger than previous iPhones, is the smallest option, measuring 138x67x6.9mm and weighing 128g. The Galaxy S5 sits in the middle at 142x73x8.1mm and 145g.
We found that the smaller dimensions and weight made the Apple iPhone the most comfortable to hold and use. However, interestingly, despite being bigger we found the G3 more comfortable to use than the Galaxy S5. This is largely due to the G3's irregular button placement.
The G3's volume and power buttons are on its back, rather than on the side and top as they are on most other smartphones. We found the placement to be a major selling point for the G3 as the buttons sit exactly where your index finger naturally falls when holding the phone one handed, and make the G3 significantly more comfortable to hold and use than the Galaxy S5.
When it comes to build quality the Samsung Galaxy S5 is on paper capable of taking more damage than the iPhone 6 and LG G3. The Galaxy S5 is IP67 certified so, unlike the G3 and iPhone 6, it's water and scratch resistant.
However, with real-world testing we found the Galaxy S5's metallic sides slightly prone to chipping and the removable backplate has a tendency to fall off when the device is dropped or meets with even moderate force.
Picking between the G3 and the iPhone 6, we found the iPhone 6 metal frame made it feel slightly more top end and robust than the LG handset. This is because the G3's polycarbonate chassis has a fake brushed metal finish which is slightly less scratch resistant than the iPhone.
