Fantasydao Compatible with Huawei Mate 20X [Magnetic Adsorption Case] Metal Frame [Clear Tempered Glass Back] 360° Bumper Slim Fit [Ultra-Thin] Lightweight Cover for Huawei Mate 20X(Silver)

I found that in areas with weak signal I would have one less bar on average with this case on vs non-metal cases. The quality is nice on the case though. It is a little slippery, but so is the phone without a case.

I ordered this in silver. Received black...did a return and received black again. Did another return and finally received the silver. While the seller was very apologetic and quick to resolve the problem, I ultimately had to remove the case because my reception was awful...calls would cut in and out constantly. It's a nice case and I loved the look, but killing my reception was a deal breaker. Recommend the seller (hence, the two stars) but do not recommend this case.

I can't figure out how to get this on the phone and will have to return it

This case looked great. Sadly the first time I dropped my phone the glass shattered into sharp pieces. I do not recommend this case.
