ZTE is the fourth largest smartphone supplier in the U.S. and the second largest in the no-contract market. This month they announced the availability of the next generation of the ZMAX series, the ZMAX PRO. It’s available through MetroPCS for the affordable price of $99.00 after instant rebate. The ZMAX PRO breaks new ground as it is the first US carrier supported phone under $100 that features a fingerprint sensor, and a 3400 mAh battery. But seriously, a $99 smartphone? How good can it be?
Well, the ZTE ZMAX PRO will surprise you with its high performance for such a competitive price. The phone is packed with many of the features you would expect from a phone costing significantly more including:
- A monster 6” Full HD LCD Display with resolution of 1920 x 1080.
- Powered by SnapDragon 617 1.5 GHz Octacore Processor, + 2 GB of RAM
- MicroSD slot
- Powerful 3,400 mAh embedded battery that lasts a full day
- Android 6.0.1 Marshmallow OS
- 13MP rear and 5MP front facing cameras
- 32 GB of internal memory upgradeable to 128 MB with the micro SD slot
- Fingerprint sensor for added security
MetroPCS has also added its own app store offering Metro PCS apps that come pre-installed on the device along with a variety of utilities and games, although in reality this is little more than a link to the Android app store. The ZTE ZMAX PRO also features a USB Type-C connector. The cameras have the ability to frame, shoot and edit pictures on the go. Power hungry video games are playable without pause or problems, although some apps can take a little longer to load.
Unusually, the ZTE ZMAX PRO also includes a Qualcomm® Quick Charge 1.0 enabling you to charge the phone up to 40% faster than older phones.
In terms of styling and comfort, although it’s a lot of phone, it’s comfortable to hold in the hand. The soft touch back features the fingerprint sensor, which is fast and accurate. It can also be used to quick launch apps based on the finger that you use and you can also answer phone calls just by pressing the sensor.
The original retail price of the phone is $179.99 but Metro PCS’ mail-in rebate offer whittles it down to just under the $100 price mark which makes this phone an exceptionally good deal.

The Coolpad Group Limited is a Chinese telecommunications equipment company headquartered in Shenzhen, Guangdong, China. It’s the largest smartphone company in terms of sales in the domestic market. With 6 R&D facilities worldwide, the company continues to invest heavily in developing innovative cellular, wireless, and mobile technology products. Producing and launching over 85 different models and 50 million handsets a year.
Released in June of this year, the Coolpad Catalyst 3622A is the fourth phone from Catalyst to reach the US market. It’s a budget, 5” 4G LTE smartphone packed with many of the features of higher cost smartphones, including full built-in video calling, Android 5.1 Lollipop operating system, and a fast quad core processor for keeping in touch with friends and family and entertaining oneself on the go.
The cameras are adequate for everyday use and include a 5mp main camera with LED Flash as well as a 2mp front facing camera.
The phone comes with a 2200mAh battery. MetroPCS offers the Coolpad Catalyst with up to 80% off the retail price, meaning that after the mail-in rebate the phone could be in your hands for as little as $19.00. Not surprisingly, it’s one of the lowest cost phones in their portfolio.
While the Coolpad Catalyst is well equipped, and has 4G LTE connectivity, most of its features reflect its low budget price including the 480 x 854 pixels screen resolution, one of the lowest screen resolutions currently available. RAM memory is also only 1 GB and the low pixel cameras mean photographs could turn out looking grainy.
In terms of looks and aesthetics, for the price you definitely are not going to get a Samsung Galaxy S7, but the phone adopts a curved handheld shape. The front is glass and the glass is contained within a plastic frame. The rear shell, also plastic, wraps around to meet the frame. The display takes on a bright gray hue when off and it stands out starkly from the pitch black bezel. Overall, a reasonable, low cost, big screen entry level solution with above average call and sound quality. Designed for the smartphone newbie, or those that don’t expect or demand too much from their phone.

If you insist on Samsung quality but you don’t want to pay Samsung’s high-end phone prices, the entry level Galaxy Core Prime could be just the phone you’re looking for. It’s an all-plastic phone that manages to look and perform dependably above its weight. Its slim line good looks are inspired by some of Samsung’s bigger, more powerful phones, so while it is a budget model, it doesn’t perform like a budget phone.
The build quality is good, with smooth curves and a brushed metallic bezel and the battery is removable so you can add up to 128GB of storage via the microSD card slot that sits on top of the single micro SIM slot.
The phone runs on a 1.2GHz quad-core processor – a SnapDragon 410, with Adreno 306 graphics, 1GB of RAM and 8GB of storage (5.3GB is usable). In general use the phone performs at a good rate but for some heavier apps there can be slight delays when launched. At 4.5” inches, the WVGA screen is also smaller than some of the currently popular 5.5” phablet style phones, but it certainly makes up for lack of size with ease of portability as it could comfortably fit into a shirt pocket, so it’s perfect to carry around for summer months wearing just shirtsleeves.
The Samsung Galaxy Core Prime has 4G LTE data speeds so you can stream high-quality videos, video chat and share photos with friends. It runs on the Android 5.1 Lollipop operating system with the TouchWiz interface to make navigating simple.
As far as picture power is concerned, the phone has a front facing 2MP camera for easy selfies and a higher quality 5MP camera on the back with Auto Focus and a rear LED flash.
Battery power is boosted when it’s in Ultra Power Saving Mode; the battery continues to power the phone even when it’s critically low. It works by turning most of your screens to black and white and shuts off nonessential apps, so your smartphone still works when you need it.
T-Mobile USA was selling the Galaxy Core Prime for cash for $139.99 or just $5.84 per month with no money down.

With its Super AMOLED display, the highly successful and value for money mid-range Samsung Galaxy J series offers quality and performance capabilities that would have been considered high-end even just two or three years ago. The J7, bigger brother to the J5, enables you to upgrade your photo-viewing, video-watching and gameplay sessions with rich, true-to-life color reproduction and an exceptional contrast ratio for deeper blacks.
The Samsung Galaxy J7, which was introduced a little earlier this year, features an immersive 5.5-inch HD Super AMOLED display, a 1.7GHz Octa-Core Exynos 7870 SoC, with 2GB of RAM, 16GB of on-board storage, a 13-megapixel rear camera, a 5-megapixel front camera, and a 3,300 mAh battery. MicroSD support is also included, as is LTE network connectivity. Running on Android 6.0.1 Marshmallow, T-Mobile and MetroPCS, the two major service providers that stock the J7, have different marketing strategies to entice you to buy the phone, and both of them are tempting.
T-Mobile USA offers the Samsung Galaxy J7 for only $239.99, and comes with a second phone free provided you pay with a prepaid MasterCard credit card. While MetroPCS USA does not offer a free second phone but opts instead for a super low price for the J7 of just $179.00.
Whether you’re watching an HD streaming movie or reading a book, the Samsung Galaxy J7 is more involving thanks to the large 5.5″ HD Super AMOLED display. And while the 13MP main camera captures clearer photos, the 5MP front camera gives you fast and flattering selfies even in low light conditions. The 3,300 mAh battery has the power to keep up with your demands. The phone comes with in-built Ultra Data Saving which compresses data and restricts background apps from chewing up too much data, thereby supplying an unfailingly fast and cost efficient 4G experience.

The new LG G5 is the first modular smartphone from the South Korean company, and it comes in an all-metal design, so you can upgrade it with accessories, but still appreciate the sleek look and feel. Key new features for the LG 5 include a uni-body design, an easy to slide-out battery, and MicroSD card slot, so you can add more power and memory quickly and easily. The screen is a 5.3” Quad HD screen with a high-contrast display with daylight mode.
As far as cameras are concerned, they are dual rear-facing with standard and ultra-wide-angle lenses. There’s an 8MP camera at the front and 16MP on the rear. The 135° lens means you can capture a sprawling skyline, a stadium concert, or the full length of a beach. You can also zoom out ultra-wide (0.5X) – it’s a first for a smartphone. You can take a variety of photos and videos from a micro close-up to a macro scene by simply pinching the screen.
The phone measures 149.4 x 73.9 x 7.7mm, and unlike its G series predecessors, it’s not curved and is smaller and easier to hold. Reaching all corners of the screen is now possible.
The LG 5 features Always-on display so there’s no need to press the button to check the time, date, or notifications, just a glance gives you the information you need.
Despite the Always-on display, to minimize power consumption, LG redesigned the display driver IC memory and power management function so that the display’s backlight only illuminates one small part of the overall display. This means the Always-on Display requires only 0.8 percent of the battery’s full capacity per hour to remain functional. With consumers turning on their smartphones up to 150 times a day mostly to just check the time, the G5’s Always-on Display has been designed to make a notable difference in the life of the battery over the course of the day.
For greater connectivity, the LG G5’s Friends Manager app enables you to connect, interact and play with all your LG owning friends.
T-Mobile is currently selling the LG 5 for $629.99 or for $26.25 a month for 24 months with $0 down.
