Samsung did a great job of fine-tuning its software on the
Galaxy S6 and Galaxy S6 edge, and multitasking issues aside, both phones are
among the fastest on the market as a result. Of course, the Exynos 7420
processor, which is more efficient and powerful than any of the chipsets being
used by smartphone manufacturers in 2015, can take equal credit. Both the
processor and optimized software come together to create the best software
experience we have ever seen on a Samsung smartphone, and in a speed test carried
out by TomsGuide, the Galaxy S6 managed to best the competition in almost all
real-life use cases that were part of the test.
The test included things like loading a PDF file, opening
the camera app, Wi-Fi speed, and performance in games, in addition to
benchmarks that tested the graphics, memory, storage and overall performance.
Except for the camera opening time, the Galaxy S6 managed to score the first
position in all the non-benchmark instances. The LG G4 was slightly faster at
opening the camera, which is a good indication that constantly keeping the
camera process in memory – like the Galaxy S6 does – might not be enough to make
the camera app open quickly all the time.
