We know you’ve already got a smartphone sitting on your desk or tucked in your back pocket (you might even be reading this article on one right now), but given how much we rely on our devices, you might be due for an upgrade sooner than later. Lucky for you, we test a lot of phones here at Underscored, and you can find many of them on sale during the last few hours of Amazon Prime Day.

From deals on brands you know like Google and Samsung to burgeoning names like OnePlus, our editors have rigorously tested each of these smartphones so you can find the best one for you before the Prime Day sales run out.

Amazon Prime Day Google deals

The first foldable in Google's smartphone lineup, you can grab a Pixel Fold with 256 GB of storage for $600 off.

Stunning design, performance and camera quality make the Google Pixel 8 Pro a great smartphone choice outside the Apple ecosystem. Take 30% off the 128GB Pixel Pro 8; those who need more storage capacity can score 25% off the 512GB model.

Amazon Prime Day Samsung deals

The A35 is a strong smartphone choice that almost took the top spot as our best budget smartphone. Now you can get it for an even better deal at 25% off.

While the Galaxy S23 FE performed well in our testing, we didn't love the standard $600 price point. But for Prime Day, you can grab a 128GB model for $150 off.

The Z Flip 5 is most recently upgraded version of Samsung's Z Flip phone. With lightning-fast performance and a stunning 6.7-inch screen, you can take home the Z Flip 5 for more than $400 off during Prime Day.

If you want the newest phone in the Samsung lineup, you can preorder the Z Flip 6, which comes out later this month. Get double the storage with the 512GB version for the same price as the 256GB, plus a $200 Amazon gift card when you preorder.

The most basic model in the Galaxy S24 lineup, the S24 still delivers a premium feel, which you can grab for $200 off.

The Galaxy S24+ comes preloaded with a ton of AI features designed to make managing your life easier, plus a rich quad HD screen for watching videos on the go. Take 27% off the S24+ in five different colors right now on Amazon.

Features like a sleek, easy-to-hold design and incredible battery life make the S24 Ultra a premium phone in Samsung's lineup. Take almost $400 off the S24 Ultra, which also comes with the S-Pen for even easier touchscreen navigation.

Amazon Prime Day Motorola deals

A more modern version of the Motorola Razr you may have loved in the early 2000s, this foldable smartphone is 40% during Prime Day.

Amazon Prime Day OnePlus deals

For under $300, the OnePlus Nord is a solid choice if you just want a bare-bones smartphone, and now you can get it for under $250 during Prime Day.

Another foldable smartphone option, the OnePlus Open delivers excellent battery life, good camera quality and a great multi-tasking experience. Grab this 512GB model for $400 off.

The 2024 OnePlus 12 is an excellent flagship phone that performs just as well as other thousand dollar phones from household brands Samsung, Apple and Google. Score this OnePlus 12 for $200 during Prime Day.
