The model can be considered one of the best basic smartphones of 2018, bringing the major trends of the market.

Here is a comparison between the Elephone A4 Pro and UMIDIGI A1 pro.
Design
In terms of design, the Elephone A4 Pro has become a real eye-catcher for being an entry-level or budget smartphone. The smartphone is surrounded by a chic frame made of stainless steel, which has a pleasant rounding and is held in glossy optics. The back is made up of highly reflective glass with a slightly different vertical bar in color, extending to the left of the camera module to the Elephone logo. This reminds a little of the back of the Huawei P10 Pro, which also carries such a beam, but it is aligned horizontally. The available colors are black and gold and 
The Umidigi A1 Pro has a 5.5-inch screen, already with 18: 9 aspect ratio, which is still not very common to find in this range. The screen has an HD + resolution with Sharp TDDI In-cell technology and the finish of your glass is rounded at the ends (2.5D). The rear is also slightly curved, which will certainly offer a more comfortable use. In terms of dimensions, the Umidigi A1 Pro measures 145.3 x 69.1 x 8.5 mm, weighs 173 g and comes in black, blue and silver. The phone comes along with dual back cameras. The cameras are placed in the middle towards the top bezel. The camera is placed vertically to each other with the flashlight coming in between the camera and fingerprint sensor.
Display
The Elephone A4 Pro features a 5.85-inch display with a resolution of 1440 x 720 pixels. The display is almost rimless at the top, left and right and has a cut-out for the Phone receiver, the sensors, and the front camera. In return, the lower edge of the display has been reduced to a minimum, since there is no need to clear space for a front camera, as would be the case with a Tri-Bezel-Less design. Sure, you can argue about the notch, but in the case of the Elephone A4 Pro, the design looks very well done. If the Notch is well integrated on the software side, nobody should be bothered by it. According to Elephone, the A4 Pro should be smaller than an average 5.5 “smartphone, but concrete dimensions have not yet been released, and With the Umidigi A1 Pro, the new 18: 9 format is now also being introduced in the ultra-low-budget class. The phone has a 5.5-inch display with 1440 x 720 pixels installed. The mobile phone thus achieves a pixel density of 293 ppi and is therefore only just below the Retina value. Although the display is not as sharp as current Full HD panels, it is sufficient for a pleasant picture. The display of the Umidigi A1 Pro works with IPS technology and should also bring stable flashing angles and good brightness. The touch screen will probably be able to register 5 touch points at the same time. It is to be hoped that the A1 Pro delivers a good display quality. Even if the specs let assume, one must wait with such a favorable device the first test reports, in order to get really a certainty.

The sensor of the main camera is an unspecified sensor from Samsung. Both on the front and on the back there is an LED flash.
