Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 20400 Hz | ≤ 90 % brightness setting |  |
The display backlight flickers at 20400 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 20400 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17900 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

Pros
Cons
即使三星的Galaxy XCover 4并没有像想象里那么坚固，但却比许多其他非常脆弱的智能手机获得了更好的保护。坚固的塑料外壳看起来不笨重，它甚至可以更换电池。防水防尘能力与前代相比有所增强，扬声器现在在手机潮湿时仍然无可挑剔。在水中使用后，我们在后盖下方发现一滴水。 因此，该设备在这里需要单独地干燥处理。
该设备的存储容量可以更大些，但其应用广泛的操作系统和相当有用的主要摄像机还是让人折服的。输入选项多样，屏幕适当，性能足够日常使用。电池续航也符合良好的整体印象。尽管如此，我们并不喜欢该手机的音质和游戏性能。
像它的前身一样，Galaxy XCover 4并不适合极端的情况下使用，但是足以应对日常生活的不确定性因素。坚硬外壳下，隐藏着一个坚实的，中低档智能手机。
需要能在极端情况下使用的高端手机用户，将不得不在其他专业设备中选择。三星提供了一个坚实的设备，适用于稍微恶劣的日常环境，如徒步旅行或偶尔访问一个多尘的施工现场。由于该设备相对较便宜，定位系统很优秀，因此非常适合于这些情况。
