Question whats the difference between Android's screenshot and Camera take picture?

[DIYerLL]

Hi all.

I used Android phone to do: 1) take a screenshot; 2) camera take a picture; and sent both to ESP32_TFT through BLE by MIT APP, the 1) got better display , but 2) got realy bad display, its why I guess maybe the 1) and 2) working at different principle?

Thanks for any clue.

On an Android phone, a screenshot captures the image currently displayed on the screen, while taking a picture uses the phone's camera lens to capture a real-world image. Screenshots are often smaller in file size and may not be as high quality as pictures taken with the camera.
