There are a few ways to rename images on Android. You can use the File Manager, or you can use the Android Image Editor. The File Manager is a more common way to rename images, but it can be a little bit tricky to use. To start, open the File Manager and select the image you want to rename. Then, drag and drop the image onto the desired location in your Android phone. When you release the mouse button, your image will be renamed according to its new name. If you want to rename an image using the Android Image Editor, first open it and select the file you want to rename from within its context. Then, drag and drop it onto the desired location in your phone. When you release the mouse button, your image will be renamed according to its new name.
