Samsung Galaxy S9 and S9 Plus review: Excellent, not monumental


Despite not feeling like a major improvement over last year's flagship, the Galaxy S9 is still one of the best phones around.

Dual Aperture effective in low light ; Excellent cameras overall ; Speedy performance ; Long-lasting battery

Not a major improvement over last generation

Samsung Galaxy S9+


It's not revolutionary, but the Samsung Galaxy S9+ sets the bar for smartphones in 2018, with the best hardware features you can get.

Gorgeous screen. Beautiful body. Spectacular network performance. Dual main cameras with excellent low-light capture. Loud audio.

Camera software oversharpens images. AR Emoji and Bixby disappoint.

I don't think the past 12 months make a great innovation year for smartphones. That doesn't mean we're seeing bad phones, it just means we aren't seeing game-changing phones. With in-display fingerprint sensors coming at the end of 2018 and 5G networks...

Samsung Galaxy S9 Plus first impressions: Improving upon the S8 Plus just where it was needed


Samsung announced its yearly Galaxy S series update with the S9 and S9 Plus. After a few days of use, it's clear the S9 Plus corrects some things from last year's model while building on the Galaxy foundation. It is sure to be one of the top...

Samsung Galaxy S9 Plus review


The Galaxy S9 Plus is a masterpiece.

Gorgeous design ; Brilliant, colorful display ; Feature-packed camera ; Excellent low-light photo quality ; Good sound from stereo speakers

Battery life could be better ; Live Focus produces fuzzy photos

The Galaxy S9 Plus brings a refined design, but it’s the ‘reimagined’ camera that makes this phone stand out, and worth the high price tag.

Samsung Galaxy S9+ vs LG V30


A glance at the Samsung Galaxy S9+ next to the LG V30 wouldn't be enough to pick a favorite. And while these two Android phones are similar, they're far from identical. Let us walk you through the factors setting them apart.

Samsung Galaxy S9+ vs Galaxy Note 8


Both the Galaxy S9+ and the Galaxy Note 8 are big, shiny and pretty to look at, and pack all of Samsung's latest bells and whistles. One can legitimately be confused when trying to decide between those two. So, let's take a closer look!

Samsung Galaxy S9+ Review


The Samsung Galaxy S9+ is available from Samsung and all major carriers. Take care when you buy, however, as each retailer sells the phone for a different price. The Galaxy S9+ is undoubtedly the best Android phone on the market and our pick as the...

The dual variable aperture cameras take stunning photos and portraits in both bright and dim conditions.

Intelligent Scan is not as effective or quick as Apple’s FaceID.

The Galaxy S9+ is the best Android smartphone on the market.

Galaxy S9 and S9+ Review: The Android Phones to Beat


The Galaxy S9 and S9+ improve upon the best Android phones of last year in several key ways, including performance, low-light photography and slow-motion video recording. The displays are also brighter than the S8 and S8+, while the stereo speakers are...

Good camera in low light ; Fun Super Slow-Mo video ; Brighter display with even thinner bezels ; Swift performance ; Long battery life

AR Emoji need work ; Intelligent Scan a step behind Face ID ; Bixby Vision AR features feel half-baked

While AR Emoji and other tricks don't impress, the Galaxy S9+'s improved camera, brighter display and faster performance add up to make this a worthy iPhone X rival.
