Strongest smartphone holder for the windscreen?

Hi, can anyone recommend a good phone holder that keeps reasonable on the windshield and possible not broken? Likewise, as a magnet holder, the main thing you can attach it to the windshield and the smartphone does not fall down even with potholes or heavy stunts. I previously had this bracket:

At the disc she has kept super and bombproof, only the mechanism was completely over after 16 days. I do not want to have that again.

Must be held a Huawei p20 pro.

Thank you for any serious and reasonable proposal.

You certainly can't attach a magnet holder to the windshield. Because on a glass pane holds no magnet.

Why should not something on the windscreen? Self-assembly only with magnet: https://www.amazon.de/...B00UJH8BHS
