Samsung Galaxy Core Prime review: Core values

A poor display

The Samsung Galaxy Core Prime features a 4.5" screen with WVGA resolution, or 480 x 800px in concrete numbers. The Core line rarely deviates from those numbers and even then, it doesn't go further than a 4.7" 540 x 960 screen.

It's a regular TFT LCD unit, which initially looked quite good. Our test showed that while viewing angles are decent for a non-IPS display, its downfall is the poor contrast ratio.

The image looks way too washed out, which also negatively affects colors, they look dull and lack saturation. This display is not on the same level as the one on the Grand Prime, despite both phones sharing the Grand epithet.

Our measurements show a rather good 1:1000 contrast ratio, but that was achieved only in pitch darkness. The display is rather reflective so even a little ambient light can spoil the contrast. Also, we get the sense that the contrast curve of the display is not set right, which makes matters worse.

The pixel density and sharpness are unimpressive too. You see, 207ppi isn't much to talk about. It's not bad, text is readable and photos look sharp enough, but they are not as nice looking as on better LCDs.

Here's what the LCD matrix looks like under magnification.

We would like to say that contrast was sacrificed in the name of brightness, but that's not the case. The display isn't very bright either and we never went below 50% on the slider.

Again, there's no ambient light sensor so you can't rely on automatic brightness to adjust the screen as you move between locations with different lighting.

Not that even going full blast helps the display outside, where bright sunlight washes it out pretty easily. This is once again an issue of contrast and reflectivity- the difference between white and black is small under good lighting conditions, but when glare comes into play things get very difficult to see.

Optional dual-SIM, optional LTE

The Samsung Galaxy Core Prime is surprisingly well-armed in its connectivity department. The base model is a single-SIM with 2G (quad-band) and 3G (quad or six band) support. There is a dual-SIM version too where the second card gets quad-band 2G connectivity.

For data there's HSPA with 42.2Mbps downlink and 5.76Mbps uplink on the primary SIM. Two versions - G360G and G360F - have LTE connectivity and thanks to the current Snapdragon 410 chipset, it's of the speedy Cat. 4 variety. It should offer up to 150Mbps downlink and 50Mbps uplink (same as the iPhone 6) where the carrier network allows it. Unfortunately, the LTE models are only available in China and Taiwan for the time being.

Local connections are handled by single-channel Wi-Fi b/g/n with Wi-Fi Direct for file sharing but no DLNA for media sharing.

There's also Bluetooth 4.0 and even NFC, which is rare to see on phones in this market segment. The Galaxy Core Prime will do some good in bringing NFC to the masses as the short-range wireless tech has had a slow burn for years.

For positioning, the phone relies on the standard A-GPS, plus GLONASS and Beidou, the Russian and Chinese answers to GPS. Beidou does not have worldwide coverage, but China is an important market for Samsung and this phone in particular.

A microUSB 2.0 port handles charging and wired data transfer duties. It doesn't have extras like MHL or USB On-The-Go.

Battery life

Running on an average 2,000mAh battery the Samsung Galaxy Core Prime relies on the new Snapdragon 410 chipset for great battery life and it worked. It helps that the display isn't terribly bright, but the handset showed impressive results in all categories.

It starts off with a great talk time - a little short of 17 hours. We should note that the test was done on a single-SIM LTE version of the Galaxy Core Prime. Web browsing and video playback both drain the battery in about 10 hours.

These scores, combined with an efficient standby mean the phone will last you three days of use, two if you push it harder.
