Blackview Tab 12 Pro 评测 - 配备双 SIM 卡和高达 14GB RAM 的 4G 平板电脑，售价低于 170 欧元（约合 185 美元）
以户外产品闻名的中国制造商 Blackview 推出了 Tab 12 Pro 平板电脑，将自己定位在入门级到经济型中端市场。型号名称中的数字并不代表屏幕对角线。Tab 12 Pro 只有一块 10.1 英寸的 IPS 屏幕，分辨率高达 1920 x 1200 像素。
在评测期间，Blackview Tab 12 Pro 的售价约为 130 至 170 欧元（约合 140 至 185 美元）。鉴于给定的配置和 8 GB 内存（可扩展至 6 GB 虚拟工作内存）以及 128 GB 系统内存，价格低廉的Android-12 平板电脑与 Unisoc Tiger T606似乎具有很高的性价比。请阅读我们的测试是否能证实这一点。

案例 - 略有缺陷的 Blackview Tab 12 Pro
Tab 12 Pro 采用金属外壳，为这款价格低廉的 10.1 英寸平板电脑增添了几分质感。不过，它看起来并不特别抗扭，而且在我们评测的样品左侧，IPS 面板与边框之间的距离很小。除此之外，Blackview Tab 的做工还算可以，430 克（约 15 盎司）的重量也让人感觉手感舒适。
除了银色版本，Tab 12 Pro 还有蓝色和灰色两种颜色可供选择。这款入门级平板电脑的正面屏占比为 78.7%，屏幕与总表面的比例相当低。中国制造商没有说明 Blackview 安装了哪种保护玻璃。
功能 - 带 3.5 毫米插孔的 Blackview 平板电脑
尽管价格低廉，但 Tab 12 Pro 的功能却相当丰富。除了双扬声器系统、4G 双卡双待、状态指示灯、FM 收音机和蓝牙 5.0 之外，Tab 12 Pro 还配备了 UFS 2.0 存储系统。UFS 2.0 存储空间还可通过 microSD 卡扩展至 1 TB。不出所料，Blackview 的入门级平板电脑采用了速度较慢的 USB 2.0 端口，无法进行高数据传输或有线图像输出。
microSD 读卡器
我们使用参考存储卡 Angelbird Pro V60 对内存插槽的速度进行了更深入的研究。虽然 CPDT 基准测试的结果不错，但 JPEG 复制测试的数据传输速率仅为 8 MB/s。此外，它还不支持 exFAT 文件系统。

软件 - Tab 12 Pro，含Android 12
Blackview 将过时的Android-12 操作系统与内部用户界面 DokeOS 3.0 版相结合。在测试时，后者仍有 2022 年 11 月的安全补丁。目前尚不清楚未来是否会有操作系统升级，以及安全更新会持续多久。
通信和全球导航卫星系统 - 配备 4G 功能的 Blackview Tab 12 Pro
Tab 12 Pro 支持接入移动 4G 网络，但只有 6 个 LTE 频段，包括本地使用的 28 频段。这款入门级平板电脑在国内无线局域网内提供 WiFi 5，与我们的参考路由器华硕 ROG Rapture GT-AXE11000 结合使用，平均传输速率超过 300 MBit/s。

除了与卫星系统通信的内置定位模块外：Tab 12 Pro 除了与 GPS、GLONASS 和 Galileo 卫星系统通信外，由于支持手机，还使用了 A-GPS。在我们的实际测试中，定位精度并不总是令人信服。与同时用于对比的 Garmin Venu 2 相比，Blackview 平板电脑的细节显示有一两处不准确。尽管如此，其跟踪水平应该足以胜任导航任务。
电话功能 - Tab 12 Pro 支持通话
喜欢用平板电脑拨打零星电话的用户可以通过 Blackview Tab 12 Pro 的电话应用程序拨打电话。不过，通话质量不是特别好。只要用户不直接对着麦克风说话，对方就会觉得声音非常小，几乎听不懂。
摄像头 - 配备单摄像头的 Tab 12 Pro
背面的单摄像头模块光圈为 f/2.2，并配有 LED 闪光灯。1300 万像素镜头和自动对焦功能可在白天提供可接受的画质，不过照片有时会显得非常明亮和有点柔和。不过，Tab 12 Pro 在色彩还原方面还是令人信服的，不过绿色调有时会有些偏淡。不过，在可控的光照条件下，与参考色相比，没有出现真正的异常值（>15）。
Blackview 平板电脑录制视频的最大分辨率为 1080p，而 500 万像素的 FroTCam 只能录制高清视频。

配件和保修 - Blackview 平板电脑（带电源适配器
Blackview 为其平板电脑配备了 10 瓦电源、保护膜、一个相当贵重的保护套以及 USB 电缆和信息手册。此外还有一些可选配件，如 Blackview K1 无线键盘（约 45 欧元/49 美元）。
保修 保修期 在德国的保修期为自购买之日起 12 个月。
输入设备和操作 - 带面部解锁功能的 Blackview Tab
电容式触摸屏最多可同时检测四个输入，识别手指时不会出现严重延迟。层压面板的工作频率仅为 60 Hz，这意味着动画看起来不如 90 Hz 或更高频率的屏幕流畅。
Tab 12 Pro 没有指纹传感器，但可以通过前置摄像头的面部识别功能进行生物认证。Blackview 最多能可靠地识别一张存储的人脸，但这种方法（2D 方法）很不安全，而且有一定的延迟。
显示屏 - 采用 IPS 面板的 Blackview Tab 12 Pro
10.1 英寸 IPS 面板的宽高比为 16:10，分辨率为 1,920 x 1,200 像素。在我们的测量中，屏幕的最大亮度为 371 cd/m²，高于制造商的规格（300 nits），但提供的亮度并不高，照明也不均匀。APL18 测量结果也没有改变这一点--我们得到的亮度为 373 cd/m²。
Blackview 平板电脑没有使用脉宽调制进行亮度控制。

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 1260 Hz |  | |
The display backlight flickers at 1260 Hz (worst case, e.g., utilizing PWM) . The frequency of 1260 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 8702 (minimum: 5 - maximum: 343500) Hz was measured. | |||
在我们使用 CalMAN 软件和分光光度计进行的测试中，IPS 显示屏的校准效果不佳，灰阶显示出明显的偏蓝。色彩的 Delta E 值明显高于理想范围（<3），色温也设置得过低，约为 9700K。
由于 0.48 cd/m² 的黑色值相当高，Tab 12 Pro 的对比度只有约 770:1。APL 测量值（0.49 cd/m²）也无助于提高 10.1 英寸平板电脑的对比度。

在户外，Blackview Tab 并没有给人留下令人信服的印象，尤其是亮度始终需要手动调节。在盛夏的阳光下，显示内容已难以辨认，但 Tab 12 Pro 在阴暗处也会出现恼人的反光。
另一方面，IPS 面板的可视角度令人信服，平视时典型的亮度下降也只是微妙地出现。
性能 - Blackview 平板电脑采用非同一般的 UNISOC SoC
在日常使用中，Tab 12 Pro 的运行并不流畅，轻微的卡顿现象时有发生。安装的 UNISOC T606在 1200p 分辨率下常常显得有些力不从心。在我们的基准软件包中，12 nm SoC 在此价格范围内显示出稳定的性能，但 Mali-G57 MP1在 3DMark 测试中的表现比 Teclast T50在 3DMark 测试中的表现不如采用相同 GPU 的 Teclast T50。由于应用程序的问题，我们无法提供 GFXBench 的数值。

发言人
Tab 12 Pro 依靠两个扬声器，最大音量超过 91 分贝。我们的测量结果显示，这款入门级平板电脑的中音具有线性频率响应，但超高音调在粉红噪声中明显塌陷。声音图像中没有低音，在最大音量的上三分之一处会出现失真。
此外，还提供通过 3.5 毫米插孔和蓝牙 5.0 连接的有线或无线耳机解决方案。音频插孔的噪音水平在良好范围内，信噪比值约为 79 dBFS。音乐爱好者还可以信赖由 aptX、aptX HD、AAC 和 LDAC 组成的可靠编解码器。

判决
来自 Blackview 的 Tab 12 Pro 以极其诱人的价格提供了坚实的优点，却没有暴露出任何明显的弱点。金属外壳看起来并不廉价，但也不耐磨耐用。凭借集成的 LTE 调制解调器和双 SIM 卡功能，这款 10.1 英寸平板电脑不受国内无线局域网的影响，而且良好的电池续航能力也让户外娱乐变得持久。不过，缺少环境光传感器是户外使用的一个缺点。
Blackview Tab 12 Pro 的低廉价格和 4G 网络接入为购买提供了理由。
不支持外接显示器或校准不理想也是该机的不足之处，尽管考虑到价格，这些不足还是可以原谅的。另一方面，软件方面的问题更大。旧的Android 12 和更旧的安全更新并不一定适合购买 Tab 12 Pro。那些看重更新保证和（更长时间的）安全补丁支持的用户，可以通过以下产品找到更好的解决方案 诺基亚 T21 - 但诺基亚 Tab 的价格也高出很多。还有一款非常便宜的 联想 Tab M10 2022（第三代）可能）比 Blackview Tab 12 Pro 更有前途。
价格和供应情况
Blackview Tab 12 Pro 在美国亚马逊上的售价约为 140 美元。
