This is my first 3D model Upload, This is the iPhone 14 Pro, with high quality geometry including ports and speaker grills.I didn't made this to be used in games or anywhere we need Low-Poly geometry. This model is suitable for use in still renders and where having high poly doesn't matter.To change the screen texture, please replace the Screen Texture file with another image heaving the same resolution/ aspect ratio.You may not see the screen because the screen texture file is initially placed in the zip file. Just select the Screen object in blender and select the image in the zip file as the color input and emission.
