Using the Quad Lock case for your Huawei P30 is super easy. First, just slide your phone into the case. When you want to use the mounting system, simply align the case with the mount and use the patented two - stage lock. You'll feel it click into place securely. When detaching, use a gentle, even motion following the lock's mechanism. Remember, it's all about technique. As for maintenance, keep it clean by wiping it with a soft, dry cloth. Avoid using harsh chemicals as they may damage the case's material. Also, don't try to force the lock open or closed, as it can handle up to 80 kg when used correctly but might break if misused. And since it's wireless - charging compatible, you can charge your phone without removing it from the case, just place it on a wireless charger as usual.
