Here a some thoughts on the new Samsung Galaxy S8. If you want to read a more detailed test, then visit a more serious website.
Outstanding performance: 8-core Exynos processor, 4GB RAM and 64GB fast memory
Fantastic display resolution: 2.960 x 1.440 pixels, impressive sharpness, brightness and contrast.
Innovative cameras: Rear – 12 megapixel, Front – 8 megapixel (includes autofocus)
Boring speakers: underpowered, no bass
Bad battery: can be empty after less than twelve hours
Fast fingerprint reader: works great but badly positioned.
Conclusion: If you are willing to spend a bunch of money on a new smarpthone, then the S8 is certainly a good choice, if you value on good performance and processing.
