If you're in the market for a new smartphone, Amazon has some fantastic deals that you should check out.

Both the Essential Phone and Moto X4 are getting massive discounts for Amazon Prime Day 2018. What's more, both phones are being sold unlocked and include support for all four major U.S. carriers, so you can use your new device on your current carrier and take it with you if you switch providers in the future.

These deals are only available to Amazon Prime members, but you can sign up for a 30-day free trial of Prime and get access to them if you're not already subscribed to Amazon Prime.

These are some of the biggest discounts we've ever seen on either the Essential Phone or the Moto X4, and they're worth considering if you're in the market for a new device. It's also worth noting that the Essential Phone has been getting speedy software updates and will likely be one of the first non-Google devices to get Android P, so keep that in mind if software updates are important to you.
