SAMSUNG UNVEILED its Galaxy S5 flagship smartphone at Mobile World Congress (MWC) at the end of February, and clearly hopes that its loyal fans will be so impressed that they will upgrade early from its 2013 flagship Android smartphone, the Samsung Galaxy S4.
We have lined up the two smartphones head to head on paper to find out whether the Galaxy S5's specifications make it worth upgrading early from the Galaxy S4.
Design, measurements and weight
Samsung Galaxy S4: 137x70x7.9mm, 130g
Samsung Galaxy S5: 142x73x8.1mm, 145g
While smartphones typically get smaller, skinnier and lighter from release to release, Samsung has bucked the trend with the Samsung Galaxy S5.
The Galaxy S5 is taller, wider, thicker and heavier than its predecessor, meaning that those happy with the size and weight of their Galaxy S4 smartphone might not want to upgrade just yet.
However, the Galaxy S5 improves on the Galaxy S4 in other areas. While they both are built out of plastic, the Galaxy S5 has an updated perforated casing, which we found made it easier to grip during our hands-on time with the phone, with the handset sitting more comfortably in the hand despite its larger size.
The Galaxy S5, unlike the Galaxy S4, has IP67 certification too, making it the first Samsung Galaxy S smartphone to boast resistance to water and dust, with the firm clearly upping its game to compete with Sony's Xperia Z2 smartphone. It's also the first of the firm's smartphones to have a heart rate monitor, meaning it could be worth the early upgrade for fitness fanatics, and it's the first to feature a fingerprint scanner.
While the Galaxy S4 launched in only blue and white models, the Galaxy S5 will be available in black, white, blue and gold versions at launch.
Samsung Galaxy S4: 5in 1080x1920 resolution Super AMOLED display, 441ppi
Samsung Galaxy S5: 5.1in 1920x1080 resolution Super AMOLED display, 432ppi
If you're thinking of upgrading to the Samsung Galaxy S5 in hope of an improved display, you might want to think again, as last year's Galaxy S4 has a higher pixel density than its successor.
That said, the Galaxy S4 beats the Galaxy S5's pixel density by less than 10 points, which means it's unlikely you'll notice the difference in screen quality between the two, with both offering full HD 1080p resolutions and Super AMOLED display technology.
The screen on the Galaxy S5 is slightly larger, however, measuring 5.1in compared to the Galaxy S4's 5in display.
