The $550 OnePlus 6T makes me feel like I'm cheating in a world where top smartphones cost $750 or more

The OnePlus 6T runs on the same Qualcomm Snapdragon 845 chip as most top Android devices from 2018 that cost $750 or more, like the Samsung Galaxy S9 Plus, Google Pixel 3 XL, LG V40, and LG G7. That means the OnePlus 6T runs the Android operating system and apps just as well as those other top Android phones that cost $750 or more.

In fact, from my own experience, OnePlus phones tend to run slightly more quickly and more smoothly than those other top Android phones. That's likely because OnePlus phones run a comparatively light "skin" — an extra layer of software that runs on top of Android for extra features and design elements.

It also likely has to do with the extra RAM that OnePlus phones typically have compared to most top Android phones. The OnePlus 6T comes with 6 GB to 8 GB of RAM, which is on the higher end compared to most smartphones in general.

The extra RAM allows for more apps to be stored in the phone's short term memory, which means smoother and faster switching between the apps you often use.

Whatever is going on, the OnePlus 6T runs as well — if not better — than the more expensive Android competition. It's tougher to gauge the performance compared to iPhones, as those run Apple's own chips and operating system. Either way, the OnePlus 6T definitely doesn't feel slower than the latest iPhones.

Despite its lower price tag, OnePlus didn't skimp on design, either. The OnePlus 6T has a sleek metal and glass design that looks and feels unique.

The back glass, for example, has a frosted matte finish, which looks and feels superior to smooth glass, in my opinion. Only the Pixel 3 smartphones have a similar finish on the back, but they're late to the party — OnePlus already brought the matte glass texture with the previous OnePlus 6.

The front surface has bezels around the display that are just as narrow — if not narrower — as other smartphones. Even the notch's water-drop design is unique, and it's small and unobtrusive.

Like many other phone makers when display bezels became narrow, OnePlus moved its fingerprint sensors to the backs of its phones. With the OnePlus 6T, it moved the sensor back to the front, despite its narrow bezels. That's because the OnePlus 6T is the first smartphone that's available to buy in the US that comes with a hidden "in-display" fingerprint sensor. Yes, it's under the display.

The real selling point here isn't that it's the first in-display fingerprint sensor, but rather that it's back on the front of the phone on the OnePlus 6T. I truly welcome the ability to unlock the OnePlus 6T when it's laying flat on a table without having to pick it up and reach around the back for a rear fingerprint sensor.

It works surprisingly well for a first generation effort at in-display fingerprint sensor. I have some trouble when I'm in direct sunlight, and that's because of the way in-display fingerprint sensors work. They focus bright light around the sensor and finger to recognize your fingerprints, and bright external lighting apparently has a negative effect on this.

When I faced that issue on a bright sunny day, the OnePlus 6T's insanely fast face unlocking took over and unlocked the phone without issue. It's a great backup if you want it to be, or a great primary option to unlock the phone, too.

I should mention that the sharp, bright light that emanates from the in-display fingerprint sensor is uncomfortably bright in a dark room, or when you're in bed getting ready to go to sleep. It's something you can avoid by setting your home as a "trusted place" in the Android menu, just to avoid using the fingerprint sensor altogether in the dark.

The OnePlus 6T has a 6.4-inch screen that's on par or larger than than the bigger models of smartphones out there, like the Galaxy S9 Plus, Google Pixel 3 XL, LG G7, and LG V40. Those larger models tend to cost more than the standard-size models.

And yet, the OnePlus 6T offers a large display for a smaller price tag than even the smaller standard-size smartphones out there.

I'm just as happy with the OnePlus 6T's camera as I am with most other smartphones. The only exception is the Google Pixel 3 phones, which have the best smartphone cameras, hands-down.

With the OnePlus 6T, however, you don't get as many camera features as you would with a more expensive smartphone. For example, there's no optical zoom lens for better closeup shots like you'd find on the Galaxy S9 Plus, nor is there an ultra-wide angle lens for capturing ultra-wide photos, like you'd find on the LG G7. Then there are phones that have all three types of lenses, including normal angle, ultra-wide, and zoom lenses, like the LG V40.

The OnePlus 6T does have a second lens, but it's entirely dedicated to helping out with the blurry background effect for portrait mode shots. It doesn't do anything else. Despite this dedicated background blur lens, the OnePlus 6T doesn't let you adjust the background blur during or after you take a portrait mode shot.

I'm not a big selfie taker, but they look just as good as most other top Android smartphones.

As I mentioned, there are two top Android phones that give me selfie features, and they're pretty meaningful. The LG V40 and Pixel 3 phones have a secondary ultra-wide angle selfie camera lens for ultra-wide selfies that let more people and scenery into a selfie.

You can check out a full list of things that expensive smartphone have that the OnePlus 6T doesn't right here.

In a nutshell, you're not getting the following features in the OnePlus 6T that you'd find on an expensive smartphone:

• No wireless charging
• No official water resistance rating
• A 1080p resolution display versus the technically sharper 1440p displays on top Android phones
• No stereo speakers

While using the OnePlus 6T, I didn't miss any of those features I listed above that the OnePlus 6T doesn't have.

Sure, there were times when a 2x optical zoom lens would have been nice, and the single loudspeaker on the OnePlus 6T doesn't sound as good as the stereo speakers on other phones. But would I pay an extra $250 minimum for those features? Or any of the other features I listed above? No.

The only smartphone that does tempt me despite it's high $900 price tag, is the Google Pixel 3 XL. It just takes the best photos out of any smartphones. And now, when I don't use Google's Pixel 3 XL, there's a little voice in my head telling me that the photos I'm taking with other phones aren't going to be as good.

If I bought the OnePlus 6T myself, I'd have this cozy feeling that I made the right decision. I just don't see the need to spend $750+ for a sharper display or wireless charging, or an official water resistance rating.

Of course, I can't speak to those who do thoroughly value those features. If you do, then the OnePlus 6T isn't for you, and your best bets are phones like the Pixel 3 phones, Galaxy S9 phones, the LG G7/V40, and the iPhone XR and XS phones, with a lean towards the Pixel 3 and Pixel 3 XL.
