ZTE Tempo X
Next is a relatively new phone from ZTE that arrived in late 2017. Available on Boost Mobile and other regional carriers. This is a good phone that's not too big.
ZTE's new Tempo X packs plenty in a small 5-inch phone for only $79. You'll enjoy an HD screen, 5MP rear and 2MP front camera setup, and a decent Quad-core processor. One of the best aspects though is this phone runs Android 7.1.1 Nougat. A budget device that's running newer software is hard to find. It has 4G LTE and an average 2,200 mAh battery. It isn't the best, but for $79 you're getting a good setup that will work as intended. This replaced the original Tempo from 2016. Sometimes this phone drops to $49.
Additionally, consider the all-new ZTE Tempo GO. This is the first Android Go phone in the United States. What that means is this phone runs a trimmed down version of Android 8.0 Oreo or 9 Pie designed for budget phones. Offering up to date software and the best experience at the same time.
The Tempo GO is a well-rounded phone with the latest Google software and security for $79.99. Check it out.
