Here we go again. The long screenshot that my friend received from me is not clear. What's going on here?

If you use a vivo phone, the screen resolution captured by the phone will be the same. If the screen resolution of the mobile phone is low, the magnification may be blurred after screen capture; If the picture is transmitted by software, the resolution and size of the picture will be compressed and the screenshot will be blurred. It is recommended to transmit the original image as much as possible when uploading or sending screenshots.
