Celkon Mobile is a well-known name in the Indian mobile market. They are famous for making affordable smart phones. The Celkon Diamond U 4G is one such smartphone which supports 4G speeds at a very affordable price. It is a dual-SIM phone which also has a fingerprint reader for added security.
It offers up a big 5.0” display with an HD resolution and expandable storage up to 32GB. That’s a lot being offered at this price point. The Celkon Diamond U 4G is available at a price of Rs. 6,199/- in India. Let us take an in-depth look at this affordable smartphone in this review.
The Celkon Diamond U 4G has a rectangular body with rounded edges and rounded corners with a sleek profile. The back of the phone is made of plastic and features a matte gold finish. Starting from the bottom, there’s a long rectangular strip made up of drilled holes. This is the loudspeaker grill. But only half of the holes are open. There are two plastic nubs on either side of the loudspeaker grill while help props up the loudspeaker grill so that it doesn’t get muffled when set down on its back. Above that is the ‘U’ branding setting inside the picture of a fingerprint. Near the top side is the new Celkon logo. Finally, at the very top is the 8.0-megapixel camera flanked by the single-LED flash. The power button and the volume rocker are located on the right edge.
The micro USB port and the primary microphone are located on the bottom edge of the phone. The 3.5mm headphone jack and the secondary noise-cancelling microphone sit on the top edge. The front side is dominated by the big 5.0” display which appears edgeless at the sides. But it does have side bezels. The earpiece sits at the top of the display, flanked by the 3.2-megapixel selfie camera on one side and the proximity and ambient light sensors on the other side.Below the display are the two android navigation buttons; Multitasking and Back. The Home key is a pill-shaped physical key which also houses the fingerprint reader. The design review of the Celkon Diamond U 4G highlights its premium design at this price point.
The Celkon Diamond U 4G sports a 5.0” HD LCD display and has a resolution of 1280 x 720 pixels which gives it a pixel density of 294 PPI. The display is sufficiently bright and the colours are well-saturated. The contrast levels are exceptionally good which make for wide viewing angles.
The display also performs well in outdoor conditions. Though direct sunlight legibility is not exceptional, it is visible outdoors. The review of this display highlights a competent display which has beautiful colours and sufficient brightness.
The main camera of the Celkon Diamond U 4G is an 8.0-megapixel shooter which is supported by a single-LED flash. It captures decent photos with a good amount of details, in daylight and good lighting conditions. Photos taken in low light conditions are full of noise and are a bit on the darker side of the scale.
The use of flash improves things a bit, but not by a huge margin. The 3.2-megapixel selfie camera is a competent shooter and produces good images in good light. Low-light photos do not fare well. All-in-all, the pair of cameras on the Celkon Diamond U 4G are competent shooters without being exceptional.
The Celkon Diamond U 4G is powered by a Spreadtrum SC9832 Quad Core Cortex A7MP processor running at 1.3GHz. It is paired with Mali-400 MP1 graphics processor and supported by 2GB RAM. It has 16GB of internal storage, which can be increased to 32GB via a dedicated microSD card slot. It supports dual SIMs and also supports VOLTE, which is the latest communication standard in the mobile world. Other connectivity options include Wi-Fi, Bluetooth V4.0, GPS and FM radio.
The 2500mAh Li-Ion battery keeps the phone powered throughout the day. The phone works smoothly in regular day-to-day tasks. There are some intermittent lags here and there. But these are to be expected, given the fact that it has only 2GB RAM. It can play casual games smoothly and the 5.0” screen is a decent size for watching movies. The Celkon Diamond U 4G is a decent mid-range phone which performs well in this review.
