Can't the previous software of Apple's mobile phone be uninstalled?
Yes, click on the APP for downloading software for Apple phones. There is an update button in the lower right corner. Click on it, and there is a purchased item button at the top after entering. Click on it, and all the software you downloaded is in it. Go down and find the software you want to download. Click the download button on the right to download the uninstalled software again. Codewords are not easy.
