I am typing this review on my OnePlus 9 phone and love it more than I thought I would. Coming from an LG 6, it wasn't that difficult to figure out how to use this phone. My IT guy set it up, and it follows the Android phone system. I am now a believer in the OnePlus 9. A must buy worth every penny.

Phone is fast and amazing. The charger is ridiculous and only take 25 minutes for full charge. Only gripe I would have is that the fingerprint scanner is really low.

While the phone has some nice features it's never going to hold a candle to my old LG G8 ThinQ.
This OnePlus 9 over heats, Has battery drain issues. Does not have a slot for a micro SD card. Has constant performance issues.
I was excited about this phone, but it's not a very good phone. For the price, it's terrible.

Amazing phone at a even more amazing price! Originally bought a Samsung Galaxy S20 and returned it for this phone and so much better and less glitches than other brands. Would recommend!

I am both an iphone user and Android user. I picked this phone up unlocked because I've seen so many good things about it and it has not been a disappointment. It's sleek, camera is a beast, it runs smoothly. I'm Very happy with my purchase.

I paid only $250 for this so keep that in mind. For that price this phone is a STEAL! I love it and it works so smooth! I think this phone is still pretty good compared to other "cheap" phones out there.

I upgraded from OnePlus 8 to OnePlus 9. This device is excellent. The screen looks vibrant and feels great being a flat screen. I immediately updated to the latest Android and it feels very snappy.

Unacceptable camera. New OS is a downgrade.

This device is very disappointing, even though it's currently selling for around 60% Off from its launch price.
I knew going in that Oneplus had a bad reputation for camera performance, but the Oneplus 9 is a supposed flagship or flagship-lite phone from 2021, which debuted at $729. Also, multiple professional reviewers claimed that the 9-series camera perfomance was much improved from previous years. Therefore, I reasonably expected the Oneplus 9 camera to perform at least as well as the phone I was coming from, a decidedly mid-range phone from 2018, which launched at $499, and which had pretty unimpressive camera performance even for its era and price point. I was wrong. The Oneplus 9 camera is so bad, particularly in anything less than full outdoor daylight, that it performs worse than not only my previous phone, but worse than my 2014 mid-ranger, and worse than the old Moto G5 Plus, a 2017 $229 budget phone, that my kid plays with. My wife's Google Pixel 6a, which sold at the same price as the Oneplus 9 all during November 2022, absolutely blows it away under any and all lighting conditions. I wasn't looking for or expecting a great camera when I purchased this device, however the camera is simply unusable. It's a deal breaker at any price, even if like me the camera is not your top priority. And it's an absolute joke that a company would put this in a $700+ phone in 2021.
Aside from the camera, the other major disappointment was the operating system. One of the reasons I decided to try my first Oneplus was the clean look and the amount of customization offered by the stock OS. Unfortunately, I've come to learn that OxygenOS 11 (based on Android 11), which this device ships with, was the last version actually built by Oneplus. "OxygenOS" 12 and 13 (which come with the Android 12 and 13 upgrades) are actually just the ColorOS from Oppo, another manufacturer who recently bought Oneplus. And ColorOS stinks in comparison - bloated, childish looking, less customizable, and buggy.
Do yourself a favor and avoid this one. I have serious buyers remorse. There's a reason this "flagship" phone is selling for under $300 a year later.

Purple color is nice, phone is smooth. Only knocks for me would be the plastic sides and the lack of OIS on the cameras. Macro mode works well and the 65w charging is amazing.

I am more of an Apple person, but I have a second phone and I bought this one because of the price. Out of all of the android phones that I’ve had this one is the best.
