外壳和功能 - 有三种颜色的塑料外壳
你必须为黑视A52支付不到三位数的费用，这使它处于最低的入门级智能手机类别中。
相应地，机身仅由塑料制成，但它有三种颜色可供选择：浅蓝色、浅绿色或黑色。该智能手机不应受到过度的压力，否则，在屏幕的液晶中也会看到。否则，这款手机制造得很整齐，扭动时不会发出任何噪音。
黑视A52的重量在其尺寸中属于中等水平，而 摩托罗拉Moto E22i显示，你绝对可以在这里节省几克。
黑视A52提供了微不足道的2GB内存和32GB大容量存储；一些价格相近的竞争对手提供了两倍的容量。有两个SIM卡插槽，但其中一个与microSD卡共享，所以你可能不得不决定你想使用什么。用户还必须做的是没有NFC，所以移动支付服务是不可用的。
在与我们的参考卡Angelbird V60的测试中，microSD读卡器的速度与其他廉价手机持平，但在复制测试中有点落后。

通信、软件和操作 - 真正缓慢的WLAN
在这里，黑视A52 2023也不再是最新的：其他廉价的手机现在提供WiFi 5，但黑视的手机只能用WiFi 4，而且只能得到大约40MBit/s的速率，这意味着手机通过WLAN每秒只能传输大约5MBytes的数据，这对于高清流媒体来说是不够的，例如。然而，由于缺乏Widevine L1认证，这在大多数主要的流媒体应用程序中是不可能的。
LTE频率仅够在中欧地区操作该手机，你应该做好准备，在国外旅行时，你可能无法使用该手机的移动互联网。
软件是Android 12 Go，Blackview把自己的UI称为Doke OS 3.0放在上面。我们在这里发现了一些错误，例如，当通过USB连接到PC时，我们无法选择是否要充电或传输数据，因为相应的窗口并没有弹出。安全补丁是2022年9月的，因此在测试时已经过期无望。
60赫兹的显示屏和缓慢的SoC常常使操作感觉迟缓。虽然菜单仍然可以相当流畅地操作，但更复杂的应用程序或多任务处理往往伴随着严重的停顿或挂起。
指纹识别器被集成到外壳右侧的待机按钮中。它工作可靠且非常迅速。你还可以使用面部识别来解锁智能手机。然而，由于缺乏额外的硬件，这并不那么安全。

摄像机--最低的质量水平
后面的主摄像头有一个1300万像素的传感器，在光线充足的地方拍摄的照片太亮，在黑暗的地方几乎没有任何细节。此外，在近距离观察时，照片并不真正清晰。自动对焦在低光和高对比度下难以带来足够的清晰度。
在实验室的良好光线下，测试图像的中心部分显得相对清晰，但文字轮廓总是不自然地突出。细小的线条也很难看清。在曝光度只有1勒克斯的情况下，你无法识别图片上的任何东西。
主摄像头可以以最高1080p和30帧的速度录制视频。自动对焦反应延迟，而且并不总是很准确，亮度调整不时需要花点时间。总的来说，照片和视频可以作为快照使用，但它们不能满足更高的要求。
前置摄像头提供500万像素，拍摄的自拍在放大后很快就显得粗糙，在黑暗区域几乎无法提供细节。

显示屏 - 明亮和高对比度
事实上，对于一款低价智能手机来说，黑视A52的屏幕在某些方面可以让人信服：虽然1600 x 720像素的分辨率只是在级别上，但IPS屏幕不需要PWM闪烁来显示低亮度，而且它也比较明亮，提供良好的对比度，所以颜色显示得更亮一些。
400cd/m²的平均亮度离记录还很远，但它比所有的对比设备都要好。然而，这并不能使黑视A52 2023成为一个户外专业人员。反射仍然很强，所以最好在阴凉处或室内使用该手机。

性能、排放和电池寿命 - 关闭电源进行充电
ǞǞǞ Unisoc SC9863A已经有5年的历史了，实际上已经不再是最新的SoC，特别是由于其低效的28纳米节点。在性能方面，Blackview A52 2023甚至落后于其他廉价手机。
这在日常使用中是很明显的，有一些明显的停顿或应用程序完全停止工作。在某些情况下，该智能手机的温度高达40.7℃。在GFXBench电池测试中，我们没有注意到节流现象，但3DMark拒绝启动。
小型单声道扬声器几乎不能用于音乐，因为它的高音很重，听起来没有乐趣。外部音频设备可以通过3.5毫米插孔或蓝牙4.2连接；支持SBC、AAC、aptX、aptX HD和LDAC等蓝牙编解码。
电池容量相当大，有5150毫安时，但即使在轻度负载下也只能维持较短的时间：我们在浏览互联网时借助脚本测量了12：06小时的运行时间。这对一个工作日来说是足够的，但考虑到电池容量，它可以更长。
在GFXBench的电池测试中，我们还注意到，在高负荷下，电池会很快耗尽：手机在10分钟内失去了10%的电池容量，所以你甚至不能假设2小时的运行时间。
充电也是对耐心的真正考验：我们等待了几个小时，直到设备的电池最终再次充满。有时，即使手机处于待机状态，并且连接了附带的充电器，电池甚至也会放电。只有当智能手机关闭时，电池电量才会增加。重新启动后，充电也能在待机状态下进行，但手机似乎仍然非常不可靠。

Pros
Cons
评语 - 便宜，但制造成本低
我们不能真正推荐Blackview A52，即使它的价格很低，只有不到100欧元。不过，它在互联网上一些大型购物门户网站的畅销名单上，也有相当好的评价。
鉴于软件的缺陷，电池在连接充电器的情况下会放电，几乎没有任何性能，以及极其缓慢的WLAN连接，我们不能完全理解。由于充电技术的问题，我们还从总体评价中扣除了一个百分点。
事实上，摄像头不能提供良好的图片质量在这个价格范围内是很常见的，屏幕甚至可以用相当好的亮度值和可接受的对比度来说服人。
黑视A52是一款非常便宜的智能手机，有部分严重的问题，如电池不加载和WLAN非常慢。
除此之外，我们看到这款智能手机有很多弱点，在竞争中显得更加严重：与摩托E22i例如，你可以得到更快的Wi-Fi，甚至90-Hz的屏幕。与Ulefone Note 14你必须做的是没有指纹传感器，但你也得到了更多的性能和更快的Wi-Fi。
价格和可用性
黑视A52可以直接从制造商那里获得https://de.blackview.hk/products/a52-pricehttps://de.blackview.hk/products/a52-price.
它也可以在amazon.de提供。在测试时，它的价格为105欧元。
