When it comes to large-screen phones with displays that measure 5.7 inches or longer (otherwise known as "phablets") there aren't a lot of cheap choices The Apple iPhone 7 Plus and the Samsung Galaxy S7 Edge, for instance, start at $700 to $800, and even more affordable devices like the Google Nexus 6P fall at the $500 range.
Enter the ZTE ZMax Pro ($350 at Amazon). It costs just $100 and features a 6-inch screen, fingerprint reader, a 13-megapixel camera and runs Android Marshmallow (not the latest version of Android, but recent enough).
So what's the catch? Well, it's only available on the prepaid carrier MetroPCS for now, which uses T-Mobile's network. It's no real speed demon, it doesn't have a near-field communication chip (meaning you can't use things like Google's Android Pay digital wallet) and it's nonremovable battery could last longer and charge faster.
Even given all these compromises, the ZMax Pro is definitely worth considering. And if you're in the market for a cheap big-screen device and don't mind being on MetroPCS, this should be your top choice.
Design: Big, solid build
With its 6-inch display, the handset is big -- really big, and it reminds me a lot of 2014's Google Nexus 6. Due to its size, it won't fit easily in your pants pockets and if you have a small grip like me, holding it with one hand won't be comfortable, so prepare to use both hands for navigating. In addition, the phone's back cover is matte blue and collects a lot of fingerprint smudges that I had to wipe away constantly.
But other than that, the ZMax Pro's design is good. It's solidly built and I especially like the subtle rosy color accents around the buttons, camera and fingerprint scanner. And though it only has a 1,080-pixel display (in high-end devices, a display this size would have a 1,440p resolution), text, images and movies are still sharp and easily viewable.
Software: Just the basics
The handset runs Android Marshmallow 6.0.1, which has features like the more robust search assistant Now on Tap and added user security with app permissions. Marshmallow also supports the digital payment system Android Pay, but since the phone doesn't have an NFC, you can't use it. Otherwise, ZTE kept the ZMax Pro's software and interface pretty light. There are a handful of preloaded MetroPCS apps though, and since you can't uninstall them, they'll have to stay put inside your device.
Camera: For your casual photo needs
The ZMax Pro's 13-megapixel camera is a pretty sufficient shooter. Some images did end up over-exposed and the camera's burst shot feature (aka the ability to take lots of pictures rapidly in succession) takes a beat to fire up. But in general, the camera works well, especially for the kind of informal pictures you would take daily. Photos are clear and bright and retain a lot of detail at max resolution.
