Hi, as 3ds Max professional I can do a very clean and ralistic simulation of the mobile with a low-poly charge to make it more portable, in case it's necessary; or, if you prefer, a high-resolution model fully detailed.
The rendering will be done with V-ray to provide a more realistic and attractive view.
I subscribe on this project with desire and enthusiasm to work with you.
Thank you for your attention.
PS: As you can see on my portfolio I've done a Iphone X model for a client in the past, so I've experience with mobile modeling.
