Looks like your phone holder is secure.
I had been using a suction cup type that works well with a glass windshield in the summer, but didn’t work well in the winter due to frost etc.
To solve this problem, I removed the suction cup lever mechanism and replaced it with a large machine screw which screws securely into a push pin hole on the top of the dash. It’s secure year round now and I didn’t have to make any new holes in the dash to mount it.
