I use one of these from Amazon. I removed the adhesive tape and replaced it with the rough half of velcro. This way it is removable and sticks to the carpet easily. I have mine mounted between the seat bolster and center tunnel just about even with the front part of the seat. It is very easy to get to the phone and keeps it from falling between the seat and console. I will try and post up a picture tonight when I get home. I have an iphone 8 plus for reference.
