Using the Quad Lock case for your Samsung Galaxy S10 is a piece of cake. Just slide your phone into the case gently. When you want to use the mounting system, align the case with the mount and use the dual - stage lock. You'll feel it click into place, and that's it! Remember, use a smooth technique instead of pushing too hard. As for maintenance, a soft, dry cloth is all you need to wipe off dust and fingerprints. Avoid using harsh chemicals as they might damage the case's soft - touch material. Also, while the case can hold a lot of weight, don't test its limits in normal use. And you can charge your phone wirelessly with the case on, so there's no need to remove it every time.
