Android Authority

Robert Triggs | March 2023
"The Asus Zenfone 9 is a compact device that still packs more than enough power under the hood. It's compact size, Bluetooth and audio features (including a headphone jack!), and hardware gestures combine to offer a package that does enough differently to warrant your attention."

James Peckham | April 2021
"The OnePlus 9 Pro offers phenomenal performance, a vastly superior camera to the brand’s previous smartphones, and a variety of top-end features that make this a serious contender for anyone who’s in the market for a premium Android handset.The 6.7-inch 120Hz QHD display is among the best we’ve seen on a smartphone, with plenty of detail, strong brightness, and a variety of other tweaks. If you like to watch a lot of video on your phone in particular, this is a great option."

About ASUS

Asus is a well-known player in the mobile world, and in the past few years it has been known for covering specific niches in the smartphone market. Their Zenfone line of devices appeal to small phone enthusiasts, by providing very well-rounded and capable phones at a package that is not too large to operate with one hand – something hard to find in modern Android smartphones. Conversely, their ROG line of devices cater to mobile gamers, by providing a slew of hardware and software features, specifically tailored to enhance the mobile gaming experience. Additionally, Asus is one of the only manufacturers left that continues to include headphone jacks in their lineup of phones, a feature that has become exceedingly rare in today's market.

About OnePlus

OnePlus, established in 2013, is a smartphone brand that first became known for providing flagship-like devices, at a fraction of the cost compared to more expensive Android competitors. OnePlus focuses on creating smartphones with powerful hardware at reasonable prices. They also bring hardware features normally not seen in other Android phones sold in the US, such as their ultra-fast “Warp Charge” and the beloved “Alert Slider”.
