Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 240.4 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 240.4 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 240.4 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured. | |||

总结-中端手机中的屏幕素质标杆：
2018款三星Galaxy A7出色的Super AMOLED面板在我们的测试中有着出色的表现，这块屏幕亮度很高，具有极其精确的色彩还原以及稳定的可视角度。最重要的是，由于OLED屏幕的典型黑色值，它具有良好的对比度。总而言之，这是一个在这个价格范围内没有对手的屏幕。
三星自家的中端处理器给我们留下了并不那么深刻的印象。在我们的测试中，在日常工作负载下，Exynos 7885暴露出了一些缺点。三星SoC的系统性能完全跟不上高通。而配备新型海思麒麟710的荣耀 8X也可提供更加稳定的日常性能。
2018款Galaxy A7的噱头是它的三摄，它提供了极大的可玩性和不错的照片质量。超广角和实时聚焦功能为用户提供了有趣的选择，虽然后者有时会令人失望。
与荣耀8X一样，我们仍然想知道为什么三星仍然决定为其2018年的型号配备microUSB接口。这没有任何意义，特别是考虑到2017年的Galaxy A5就已经配备了USB Type-C接口。
“如果买家们正在寻找合适的中档价位设备，注重屏幕素质的人将无法绕过2018款三星Galaxy A7。”
在这个中档细分市场中有很多有趣的替代品可供选择。例如强大的Pocophone F1以及更便宜的性价比冠军小米A2。如果2018款三星Galaxy A7的价格略低一点，其出色的显示屏和广角相机使得它成为一个值得的选择。
