#Training Camp# A small mobile phone based on the Taishan School

The circuit part
was completed in 3 hours, but a considerable amount of time was spent on the differential pairs.
Planned additions: Soldering the 31P FPC socket for

the battery
and camera hardware

was quite difficult. After several attempts, I switched to a hot plate and succeeded on the first try (there was a slight solder bridge after the hot plate, which was finally resolved by referring to a Bilibili tutorial). FPC socket close-up: Driver part . Planned functions: Backlight , touch, boot logo, screen rotation, automatic brightness, application startup. Problems encountered:       VMware virtual machine can install tools: `sudo apt-get install open-vm-tools-desktop`  `suto apt-get install open-vm-tools` `      sudo reboot` //Reboot              . When compiling, use the snapshot function flexibly to prevent some strange events. During full Android system compilation, the error `/bin/sh: 1: lz4c: not found` occurred: Execute `apt-get install liblz4-tool`.  If the screen does not light up after assembly and power-on, you can use the screen mirroring tool provided in the official documentation to test if there is a problem with the Taishanpai (a component).
