We subjected the Crosscall Action-X5 to our rigorous SBMARK Display test suite to measure its performance Cons six criteria. In the results of this test, we will analyze how it fared in a variety of tests and several common use cases.
Overview
Main display specifications:
- 5.45 inches IPS, (~ 63% screen-to-body ratio)
- Dimensions: 161.5 x 77.8 x 13.35mm
- Resolution: 1440 x 720 pixels, (~ 295 ppi density)
- Aspect Ratio: 18: 9
- Refresh rate: 60Hz
Pros
- Good uniformity of brightness and color
- Precise touch
- No flickering
versus
- Too bright in low light and unreadable in sunlight
- Strong aliasing
- Low 63% screen-to-body ratio
- Impossibility The device cannot read 4K or HDR10 content
The Crosscall Action-X5’s IPS display performed best in indoor conditions, with acceptable readability and color reproduction, which suited basic functions such as web browsing (although scrolling wasn’t very smooth) and watching SDR video, where the brightness was correct and the details were well rendered.
The device was not suitable for more demanding uses such as watching HDR10 and ultra HD videos or gaming due to the lack of fluidity and visible aliasing. However, the device did not flicker.
For a device designed to be used outdoors, the Crosscall Action-X5 display was not suitable for outdoor conditions. Reading the screen outdoors was very difficult when the device was held at an angle. Additionally, users who wear polarized sunglasses will find that they need to hold the phone horizontally to read anything on the screen because the display turns black in a vertical position.
Test summary
Learn about SBMARK visualization tests: For scoring and analysis in our smartphone and other display reviews, SBMARK engineers perform a series of objective and perceptual tests in controlled laboratory and under real-life conditions. Please note that we evaluate display attributes using only the device’s built-in display hardware and related still image (gallery) and video apps with default settings. (For in-depth information on how we rate smartphones and other displays, see our articles, “How SBMARK Tests Display Quality” and “A Closer Look at SBMARK Display Tests”.
The following section collects the key elements of our exhaustive tests and analyzes performed in SBMARK laboratories. Detailed performance evaluations in the form of reports are available upon request. Do not hesitate to contact us.
How the screen readability score is composed
Readability evaluates the ease and comfort with which users can read stationary content (photos and web) on the display under various real-life conditions. SBMARK uses its Display Bench to recreate ambient light conditions ranging from total darkness to bright sunlight. In addition to laboratory tests, perceptual analysis is also carried out in real-life environments.

Measurement of luminance uniformity
This graph shows the uniformity of the display with a gray pattern of 20%. The more green the color is visible, the smoother the display.
How the Display Color score is composed
The color attribute evaluates the device’s ability to accurately reproduce colors. The measurements made are for fidelity, white point color and gamma coverage. We perform color assessments for different lighting conditions to see how well the device can handle color in its surroundings. Colors are measured using a spectrophotometer in a controlled lighting environment. The perceptual analysis of the color rendering is compared to the reference model displayed on a calibrated professional monitor.

Each arrow represents the color difference between a target color model (arrow base) and its actual measurement (arrowhead). The longer the arrow, the more visible the color difference. If the arrow stays inside the circle, the color difference will only be visible to trained eyes.
Behavior of the color on the corner
This graph shows the shift of color when the screen is tilted. Each point represents a measurement with a particular angle. The points inside the inner circle show no color change in the corner; those between the inner and outer circle have shifts that only trained experts will see; but those who fall outside the outer circle are noted.

How the Display Video score is composed
Our video attribute evaluates the Standard Dynamic Range (SDR) and High Dynamic Range (HDR10) video handling of each device indoors and in low-light conditions. We measure the tone mapping, color gamut, brightness and contrast of the display. We perform perceptual analysis Cons our professional reference monitor (Sony BVM-HX310) to ensure that the rendering respects the artistic intent.

Range coverage for video content
Primary colors are measured in both HDR10 and SDR. The extracted color gamut shows the extent of the color area that the device can render. To respect the artistic intent, the measured gamut should match the main color space of each video.
How the score of Display Motion is composed
The motion attribute evaluates the handling of dynamic content. Frame drops, motion blur, and playback artifacts are investigated using games and videos.
The video frame drops
These long exposure photos present the number of frame irregularities in a 30 second video. A good performance shows a regular pattern (a flat gray image or a drop-down pattern).
How the Display Touch score is composed
To evaluate touch, SBMARK uses a touch robot and a high-speed camera to reproduce and record a series of scenarios for the evaluation of fluidity, accuracy and response time.
This response time test accurately evaluates the time elapsed between the robot touching the screen and the displayed action. This test is applied to activities that require high responsiveness, such as play.
How the Display Artifacts score is composed
Evaluating artifacts means checking performance, image rendering, and motion defects that can affect the end-user experience. SBMARK accurately measures device reflectance and flickering and evaluates the impact of residual aliasing when playing video games, among other characteristics.
Screen-to-body ratio
The screen-to-body ratio of the Crosscall Action-X5 is reduced to 63%.
The measurements above show the reflection of the device within the visible spectrum range (400nm to 700nm). It includes both diffuse and specular reflection.
This graph represents the variation frequencies of the illumination; the highest peak gives the main flicker frequency.
