KOREAN PHONE MAKER Samsung's Galaxy S4 and Taiwanese phone maker HTC's One smartphones are arguably the fiercest high-end Android handset rivals on the market and probably will continue to compete for well-heeled punters' cash until Apple releases the next generation iPhone.
Android users across the globe are torn over which device to buy, with both flagship devices boasting features that will draw users' attention, so we decided to compare them head to head to see which one really is best.
The Samsung Galaxy S4 looks nearly identical to its Galaxy S3 predecessor, albeit for a smaller bezel and a slightly thinner design. Its casing is molded from polycarbonate plastic that, while it has proved decent at protecting against scratches, feels cheap in the hand - not something you want in a £600 phone. The case material is also a veritable magnet for grease and dirt, and we found ourselves having to clean the device multiple times a day.
On the other hand, the Samsung Galaxy S4's plastic casing is light, and at 130g it doesn't weigh you down too much when it's stuffed into a pocket.
Then there's the HTC One, which has a fully aluminium construction rather than plastic. HTC's decision to go with a high-end metal chassis pays off, as the HTC One is easily one of the nicest looking handsets on the market, giving the iPhone 5 a run for its money. The HTC One looks and feels more expensive in the hand than the Samsung Galaxy S4, which might manage to sway some potential customers.
The 9.3mm thick HTC One is slightly chunkier than the 7.9mm thick Galaxy S4, and at 143g the HTC One is weightier than the 130g Galaxy S4. However, we didn't notice any handling issues when using the device, and see this as adding to the high-end feel of the HTC One.
Winner: HTC One.
Next: Screen, performance.
