螢幕黑屏，但可以操作 The phone is black screen but can be operated

看起来你的手机屏幕黑屏，但可以通过3utools的Realtime Screen看到屏幕上的内容，而且手机也可以通过触摸进行操作。即使你更换了新屏幕，问题依然存在。

这个问题可能是由以下一些原因引起的：

1. 显示器背光问题：这种情况下，你可以看到内容，但是屏幕背景光线不足，导致屏幕呈现黑色。你可以尝试增加屏幕亮度或在光线较暗的地方使用手机来检查这个问题。
2. 显示屏电缆问题：这种情况下，可能是由于显示屏电缆受损或接触不良导致的。你可以尝试检查显示屏电缆，确认它们的连接是否良好。
3. 软件问题：这种情况下，可能是由于软件问题导致的，你可以尝试重新启动你的手机或者重置你的手机设置，看看是否能够解决问题。

如果以上方法都不能解决问题，那么可能是硬件故障引起的问题。你可以尝试联系手机制造商或者寻求专业修理服务的帮助来修复手机屏幕。

It looks like your phone's screen is black, but you can see what's on the screen through 3utools' Realtime Screen, and the phone can also be operated by touch. Even if you get a new screen, the problem persists.

This problem may be caused by some of the following reasons:

Display backlight issues: In this case, you can see the content, but there is not enough light in the background of the screen, causing the screen to appear black. You can try to increase the brightness of the screen or use the phone in a low-light area to check for this problem.

Display cable issue: In this case, the display cable may be damaged or poorly connected. You can try checking the display cables to make sure they are well connected.

Software problem: In this case, it may be caused by a software problem, you can try to restart your phone or reset your phone settings to see if that solves the problem.

If none of the above methods resolve the issue, a hardware failure may be causing the problem. You can try to contact the phone manufacturer or seek the help of a professional repair service to fix the phone screen.
