If you are wondering which phone should you buy, then read along, read our verdict and decide for yourself.
The Samsung Galaxy series has been more or less the same plastic shape and design since the Galaxy SIII, they got thinner and bigger with each versions but nothing drastic was changed. But this time, the designers left the front part as it is and changed the back cover of the device, into a perforated dot pattern with a shimmering matte finish. This gives the device a more sophisticated look than its predecessors, and makes holding it easier and with a better feel.
On the other hand, the HTC One M8, keeps its place as the best design. The device kept the same all-metal construction of the HTC One, with a nice brush finish. This makes the HTC slightly heavier than the S5, with 160 grams opposed to 145 grams on the S5.
The S5 has added a few extra things though, which the HTC One M8 doesn't have, as the Fingerprint sensor that is embedded in the home button. The S5 is water and dust resistant and it has the heartbeat sensor on the back of the device.
The HTC One M8 has a pair of BoomSound Speakers which give a very high-quality stereo sound, both are situated on the front of the device, which makes it more convenient and useful for users.
The two smartphones are equipped with 1080 x 1920 pixel displays. Both of them should have QHD displays (1440 x 2560 pixels) by the end of 2014.
The Galaxy S5 has a 5.1 inch display with 432 pixels per inch, while the HTC One has a 5.0 inch display with 441 pixels per inch.
The S5 is using a Super AMOLED display with amazing colors and excellent viewing angles. But the HTC One M8 is using a Super LCD 3 screen, which is one of the best screens out there.
Every Android device manufacturer have their own custom made interface. This goes for both Samsung and HTC. Both devices will be running the latest Android update , the 4.4.2 KitKat. With their own customized UI.
Samsung with its new TouchWiz update, will have My Magazine home screen panel, which gets you updates from all over the internet. While Private Mode can be used to hide some of the content stored on your device. And one of the best features will be the new Ultra Power Saving Mode which will extend the battery life of your device dramatically.
The HTC One M8 will be shipped with the new Sense 6.0, with many changes to the interface which made applications flatter and lighter, alongside BlinkFeed which is a feature that aggregates new for you.
HTC's Sense is considered a lighter version than Samsung's TouchWiz which has a lot of features that most users don't need and makes the device bloated. While the Sense is lighter and more polished.
Both smartphones are using the latest Snapdragon 801 SoC, which is the best processor available.
Galaxy S5 has a better one though, as it is using it on a clock rate of 2.5 GHz, while the HTC One M8 has it at 2.3 GHz.
RAM on both phones is 2 GB, which is actually low for high-end phones in 2014, but we suspect other versions will be out with more RAM.
Both devices will be available in 16 and 32 GB versions and microSD card slot to increase your storage space.
Samsung's high-end smartphones have been always known for their excellent cameras. The Galaxy S5 is no less, it has a 16 MP camera with the new amazingly-fast autofocus, HDR mode with real time preview, 4K video recording and many others.
The HTC One M8 is One-Up'ing the competition by adding a new Duo Camera Sensor. The phone has 2 cameras on the phone's back. This new setup will allow the camera to take photos at different layers to allow for a better focusing effect.
You are choosing between two excellent high-end phones. They both have more or less the same features. So, it is a tough call.
In Design, both phones stand out, but the HTC One M8 has the sleek metal look which is more protective and looks way better than plastic. But the S5 has the fingerprint sensor and heartbeat sensor which the M8 doesn't have and it is water and dust resistant.
Display is the same in both phones, colors would vary a little due to different screen types.
In the interface, the HTC One M8 would win as it is less packed. But the S5 has more features (most of which an average user wouldn't need).
Both devices are using the same processor, but the S5 is a clear winner with a better 2.5 GHz than the M8's 2.3 GHz.
S5 and M8 both have the same RAM and internal memory, but the S5 will be preloaded with bloat software that would take up space, using a microSD card would solve this problem for you.
In the Camera section, the S5 is a clear winner, as it has the 16 MP camera with the amazing reputation of the previous 13 MP camera in the S4.
So, if you want the high-end smartphone with all the extra features and excellent camera, go for the Samsung Galaxy S5.
But if you want a sleek look, with excellent finish, along side a polished UI, go for the HTC One M8.
