PA: Gaming aside, the Galaxy S9/S9+ perform rather similarly to their precursors. Surely, synthetic benchmarks will tell you a pretty telltale of a 30% better performance, but don’t expect the phone to perform 30% better in mundane day-to-day tasks. Granted, the Galaxy S8 was already an able performer on its own, and the Galaxy S9 further builds onto that strong foundation. Unfortunately, even with the speedy Snapdragon 845 and Exynos 9810, the Galaxy S9 and S9+ can sometimes exhibit hiccups and jitter. The phone stutters slightly and drops frames in some places. This is something that you notice once you use the phone, not something that you can see in benchmarks. It’s not a hardware but a software problem, yet the two go hand in had.

The audio quality coming out of the stereo speakers is good but the recent iPhones sound better to us. Granted, this is Samsung’s first crack at stereo speakers and things are only going to get better in the future.

The audio quality from the 3.5mm jack is pretty clear and satisfying. However, the phone doesn’t have much oomph to power high-impedance headphones. We tested it out with a pair of oldschool Fostex T40 over-ears (50 ohms). With Dolby Atmos on, the sound was full, crystal-clear, and detailed, with a max volume that is soft on the ears, but wouldn’t muffle out the noises of a busy street. Moving down to a 32 ohm pair, we got a bit of extra oomph.

Don’t regard Project Treble as something magical that will grant you software updates as soon as a new Android version gets released, but in theory, manufacturers should be able to push out updates faster as they will have to write significantly less new code. However, in practice, we will have to wait to see how the first wave of Treble-compliant devices will benefit from the feature – once Android P goes official, the countdown will be started and the major Android makers around will be carefully scrutinized.
