14. In addition, the screen's black level, shadow detail, and maximum brightness (310 lux) are maintained at a good level. With the help of these parameters and matte coating, the E5 can be used normally even under the sun.
However, this screen has a bit of a difference in color accuracy, and the average delta error we've measured is 9, and some colors even reach 10. As long as the error value is higher than 1, the naked eye can detect, so the E5 defect is still very obvious. In ac

Enable USB debugging on the phone2. cmd window input adb devices, you can see your own device at this time.PS: When you cannot see your device, check whether USB debugging on your phone is turned on, or if you have a mobile phone driver installed on your PC.The second use of wireless WiFi connectionFirst, learn a little bit about the underlying knowledge:T

First, whether locally or remotely, if you need to move or copy more files and are not too large, with the CP command and MV command less efficient, you can use the Tar tool to be copied/moved content to package/compress, and then copy/move, and finally unpack/decompress.
In addition, it is also a key technique that you do not have to copy after the tar packaging/compression, unpack/decompress, you can package/compress the other side through the pipeline to perform copy unpack/decompress.

The android terminal adbd service needs to enable port 5555 to establish an ADB connection. If port 5555 is not enabled, you cannot use network debugging to check whether network debugging is available: # netstat
If port 5555 is enabled, the connection can be performed:> ADB connect 192.168.x.x if netstat shows that port 555
When compatibility is required for automated testing, the previous practice was to install different versions of browsers on each executor. In fact, this would be a waste of resources. Now we have docker containerization technology, make everything simple
1. First, install a Ubuntu server. You can create a virtual machine in workstations.
2. Use xshell to connect after the virtual machine is created,
2.1 install docker
2.2 obtain an image
Docker pull selenium/hub docker pull selenium/node-F

For this TXT document, it's much easier to read from the Matalb.
For example, a test.txt file with the content "17.901-1.1111 33.045
