Power and Performance

In 2015, Samsung unveiled the Galaxy J7, a mid-range phone-tablet hybrid that received high marks for its blend of function and affordability. It's available in black, blue and gold and offers some desirable features usually reserved for pricier devices, including dual-band Wi-Fi and near-field communication.

With 3GB of RAM, the Galaxy J7 has plenty of speed for multitasking. There's little lag time opening new apps or working with multiple windows open, note reviewers at AndroidPIT, so you can browse websites or send text messages while listening to a podcast.

The phone has a respectable battery life that lasts a full day with basic use. You can conserve battery life even more by turning on Power Saving mode, which reduces performance and turns off the SIP battery connectivity. If that's not enough, switch to Ultra Power Saving mode and work with a black and white screen until you can plug in the charger and juice up the phone.

Camera and Connectivity

The Galaxy J7's phone features a 13MP rear camera with an LED flash for taking photos in low-light conditions. A 5MP front camera is available to use during video chats and for taking selfies. The camera also records 1080p video at 30 frames per second, so you can capture important moments in your life.

Before sharing your photos, edit them in the built-in photo editor and make your pictures pop. Crop the image to draw viewers' eyes to just the right spot. Apply filters that adjust colors, contrast and brightness to give your pictures artistic flair. Add lettering to create your own memes or comments on the photos you share with your followers.

You won't have problems sharing your photos thanks to the dual-band Wi-Fi, a feature that lets the phone operate on more than one frequency so you can access more bandwidth. The phone also has near-field communication so you can wirelessly pay for purchases while you're out and about. Data-conservation features limit the amount of data the phone consumes when you're not using it.

Screen

Arguably the phone's most striking feature is the Super Amoled HDS display, which provides deep contrast and rich color expression. No matter what you're viewing, you see more vivid colors, and the screen's maximum brightness is crisp enough to help you see what's happening even under the outdoor sun. The brighter screen makes it easier to aim the camera for the perfect shot or check the navigation map while you're on the road.

With a 73.1 percent screen-to-case ratio, you have enough room to review your photos, play games and watch videos on the 5.5-inch screen without feeling like you have to squint. The 720-pixel resolution produces sharp graphics that make viewing a pleasure even at an angle, despite the fact that it's not as sharp as higher-end smartphones, according to AndroidPIT. However, it's more than adequate for everyday use, and many users don't notice the difference in graphics quality.

Storage and Security

Samsung gives the Galaxy J7 16GB of internal storage, which is adequate space for storing downloaded apps and other files. If that's not enough, you can insert a microSD card to expand the storage to 256GB. You aren't able to store apps and system files on the card, but it provides plenty of room to hold your music, images and videos so you can carry them with you at all times.

You also get amped up security features on the Galaxy J7 that let you restrict access to your data. In 2016, Samsung included a fingerprint reader on the J7 Prime in addition to the PIN locking function. This lets you set the lock and rest easy knowing your phone has an extra layer of protection. To unlock the phone and gain access to your information inside, scan your fingerprint to show the phone that it's in the right hands.
