Samsung Galaxy S4 vs. HTC One: Camera
The Galaxy S4 has a 13-megapixel rear-facing camera, an upgrade from the Galaxy S III's 8-megapixel snapper. The most significant camera upgrades are all software related, however. 'Dual Shot' allows users to take a photo with the front and rear cameras simultaneously using selected templates, 'Drama Shot' takes 100 shots in four seconds and 'Cinema Photo' is similar to Nokia's Cinemagram feature picking one part of the photo to move while the others stay still - somewhat like an animated GIF.
There's also "Sound & Shot' which takes a picture and captures up to nine seconds of audio, and 'Story Album' which groups photos together somewhat like a timeline. Finally, an 'Eraser' mode takes a series of pictures, allowing you to remove unwanted people or objects in the background.
'Dual Shot' allows users to take a photo with the front and rear cameras of the Galaxy S4 simultaneously.
HTC is betting on a new camera technology altogether to win over consumers. The One has a 4-megapixel sensor dubbed the 'UltraPixel' camera. The custom image sensor uses enlarged pixels that the company says can absorb up to three times more light than those inside "most leading 13-megapixel phone cameras."
HTC promises that the use of UltraPixels make for an improvement in low-light performance and there's also optical image stabilization (OIS) and an f2.0 aperture, the largest available on a smartphone camera. In addition, the 2.1-megapixel front facing camera uses an ultra-wide angle lens, the same seen on the HTC Windows Phone 8X.
The HTC One's camera uses a 4-megapixel 'UltraPixel' sensor that makes use of enlarged pixels to capture better quality images.
The UltraPixel sensor also allows HTC to introduce a new media called "Zoe". It enables users to capture up to 20 photos and a three second video simultaneously. The feature looks similar to Twitter's Vine videos or the Cinemagraphs used on the Nokia Lumia 920 but you can only share the files through YouTube and Facebook, or on HTC's servers for a limit of 180 days.
Samsung Galaxy S4 vs. HTC One: Internals
Naturally, both of these handsets boast impressive specifications. The Galaxy S4 is powered by a 1.9GHz Qualcomm Snapdragon 600 processor and has 2GB of RAM. The 16GB of internal memory will be expandable by a microSD card slot located behind the rear battery cover, though 32GB and 64GB models will be available in certain markets. A 2600mAh battery is also a significant upgrade from the Galaxy S III's 2100mAh battery.
