    I have been having issue with my phone mount suction kept falling off while driving. Here is the list of what I have tried so far:
    1. clean the dash well before stick on the suction. I placed it on the left side of the dash. Stay on for a couple days.
    2. i moved to the middle dash where the plastic panel is but no help. It still falls off.
    3. i bought the disc to have the suction cup sit on but the dash has a slippery texture and the disc glue can not stay on.
    4. on a hot day, i placed the suction cup onto the windshield glass. It felt like it will stay on but over night, it came off.

    I ran out of ideas. please help.

    Not sure what type youre using, but this is what I use. Big thing is surface prep, clean the area where you will be sticking the adhesive with something like rubbing alcohol. This will remove any body oils or detailing products. Mine has lasted super long, until I left my phone on the mount on a day when it was 115 out.

    This is an easy one.

    IF.....the suction cup won't stick to GLASS, the the cup itself is damaged or defective.
    Yes, they do go "bad" after a few years of being left in the heat.

    BUT......you should not expect to get a suction cup that will stick to a modern day dashboard.
    They just aren't smooth enough.
