More than You Pay For
For an $80-$100 phone it's decent. Unfortunately, many features that have been standard since the galaxy 4 are not here, most notably :
NO WATER RESISTANCE
The display is garbage. It is literally the awful. 1. It has zero of the benefits you'd expect in a modern phone. No Gorrilla Glass, no Dragon or Sapphire glass, heck, zero scratch resistance, at all. It's not full hd. People want 4K, or at minimum, the 2012 standard 1080p. Not here. 720p TFT (not OLED, UHD, QLED etc, a TFT 720p $3 digitizer (the cost of a replacement on Ebay/Alibaba. Originally used in the early 2000's for Motorola Sidekicks, this should not be on a $30 device, never mind an $80+ one. The RAM is also very low for modern apps and games at 2GB instead of the 3-4GB standard for smartphones over the last 2 years. The 16GB internal storage is also a letdown, but standard in Flagship BARGAIN phones and, like the RAM, is an excusable corner to cut to keep prices down (unlike the display which should at least be a $7-$10 usd 1080p scratch resistant TFT; truly baffling). Between another 15GB of free space through GoogleDrive and the option to use a micro sdcard (the J7 Prime supports up to 256GB, so I would assume this is the same, though I could not find that specification.) make the low 16GB of space less of a concern. It also keeps the headphone jack which is a definitely a plus.It has all the functionality of a Galaxy 9 in regards to the layout and what it can do, though the 2GB of RAM make it a bit slower, having more of an effect on multitasking and games the the lower end CPU/APU.
If you "Just need a phone", and want a 5.5" display, then this is a fine choice, though the 16GB Galaxy J7 Prime is a far better one ($110, 1080p, Gorrilla Glass, waterproof, 3GB RAM, just to name a few things). If you don't mind a smaller screen, then the iPhone 7 is far superior (and I am NOT an Apple fan) in every way.
Get a good case for this phone as if it falls from 3" on to something hard it is going to scratch. More than a foot and you will most likely crack the screen (which may be good as you can replace it with something far better for $10 usd and a free online guide from ifixit).
If this phone had an average 2015 display I would reccomend it without pause at it's price point, but it doesn't. It's literally worse than my old Galaxy 3, and that is inexcusable. This phone was a gift, and as I had the Apple Screen band kill my old phone that day, I swapped my information over to this phone before Googling the specs. If I saw 720p TFT display I WOULD HAVE RETURNED IT and settled for a smaller, but far superior screen, as most other companies (LG, Google, Apple etc.) offer 5.2" or 4.1" screens that have Gorilla Glass, or at worst, at least offer scratch resistance and 1080p (2k for the Apple, but the processor is subpar). It baffles me that this is where they chose to skimp, to this degree, with a 5.5" display. Most people who buy this phone will probably watch YouTube, want to video chat etc, and this phone is TERRIBLE in that regard. I am literally stunned. This phone released less than a month ago. This is not 2009 where 720p was not optimal, but excusable. It is not excusable now, and I am more than disappointed with both the visuals and touch recognition (it also has no fingerprint unlock which again, is standard on every Galaxy J7 model besides the Crown model).
Don't let the 5.5" display away you. Even if you are a Galaxy like myself, please, pick another option, you do not want this phone. If this thing lasts me a week with no scratches or cracks without a FULL case (which will make responsiveness and visuals even worse) I would be floored.
To reiterate, unless this is a gift to a child or someone unfamiliar with tech, I cannot, in good faith reccomend this device.
