Primo R4 Unboxing

Design & Build Quality:

With smartphones getting larger and phablets becoming mainstream, the 5-inch screen size has become the new ‘compact’. By these new definitions, the Primo R4 is a fairly compact smartphone. The edges are a bit sharp, and the general shape and feel of the device is far from comfortable, raising questions about its ‘fashion’ credentials.

The back of the device is entirely plastic and feels incredibly flimsy. Although it’s been given a glossy finish that makes it look like glass from afar, it simply does not look as convincing up close.

Button, port and speaker positioning is fairly standard for a mid-range device, with the power and volume keys on the right, USB at the bottom, 3.5mm at the top and the speaker at the rear.

Display & User Interface:

The Primo R4 has a 5-inch display with an acceptable screen resolution of 1280×720 pixels. It is bright, handles colours well and allows users to juggle between warm (which gives it a yellow tint) and cool (for pure whitish background) colour modes through a setting. The wide viewing angles work well but sunlight readability is hit due to the reflective nature of the screen.

In terms of color reproduction the rear shooter is one of the nice cameras you will see in a mid-range. While the white saturation was not at all good, as the details seemed to be washed out sometimes. Although the camera manages to keep the details of the image pretty well, even in low light.

5MP front camera guarantees crystal-clear selfies and to make video calls at any time. Both front and rear camera captures brighter images in low light conditions because of having BSI sensor.

Audio and Video

There is DTS Sound System in the Primo R4, that’s why the audio output is clean. Plugging in a pair of headphones has a rather disastrous effect on stereo quality with crosstalk rising to very high levels.

In terms of connectivity, the Primo R4 has LTE, Wi-Fi b/g/n, Bluetooth V4, OTG, Wireless Display Sharing, Hot Knot, WLAN Hotspot, OTA. It is a dual-SIM device with a separate slot for expandable storage, so you don’t have to choose between having two SIMs or extra storage space.

Gaming Performance:

Primo R4 holds 64 bit powerful quad-core processor and Mali T720 GPU which ensures higher graphic speed so that you can enjoy High Definition games easily. It handles day to day tasks and some light to medium games really well. Although once in a while it stutters while playing some heavy games.

Battery Life:

With optimized software and 2400 mAh of battery the Walton Primo R4 manages to cut through the day. Although a bigger battery would’ve been much appreciated. The fashioned focused device offers good battery life when it comes to standby time. But not quite good if you’re a heavy user. The battery drop over the 7 hours of idle time was 4%, which is quite good for the device with the 2400mAh capacity battery.Talking about the screen-on-time it gave me fair amount at 4 hours, which is more than you could ask for such battery capacity. I was using my SIM card, and all the social accounts on the device while keeping the brightness at a medium level. So, it was more than average usage, which is good.

If you do find yourself outside without a powerbank, the Walton Primo R4 does have the extremely useful Extreme Mode feature that can extend your phone’s life significantly and it will allow you to run your device for few hours with only 10% charge in the battery.

Final Thoughts:

The Walton Primo R4 is definitely a very capable affordable Android phone. The things that I liked on Primo R4 was its build quality; it has been a tremendous ride when I talk compactness and sturdiness of the device. It felt lighter than any mid-range smartphone and still somehow showed great strength.
Primo R4 hands-on review
Dear readers, should you go for the Primo R4? Well, let me clear this.
The slim build factor and the light-weight of the device is what everyone will like the most. But this device is definitely not meant for extreme users because the battery capacity is less. Graphic intense gamers will also struggle with the handset. But you can play average games with ease. This phone is particularly meant for average users who just needs to make a phone call and surf web and who loves selfies.
