A:AnswerI have had this issue with a number of stiffer rubber mounts. My solution is to clean the surfaces involved with isopropyl alcohol and use liquid rubber cement lightly applied to the rubber. Can get rubber cement at a office supply store for a few bucks. Press the unit on the surface and hold for a few seconds and then pressing firmly, activate the suction lever.
A:AnswerYes- I have a IPhone 8 with a otter box and it hods it fine. No problems while driving or turning at all. It keeps the phone in place at all times. Hope this helps you!
