ASUS Zenfone 4 ZE554KL 5.5-inch Case,Carbon Fiber Shockproof Cellhone Case,Light Thin Super Durable Snugly Fit Case for Zenfone4(ZE554KL) (White)

This is a beautiful case. Built well, great look, however there is a major issue that i just found. It interferes with GPS and phone signal and it's a dramatic difference. My new Zenfone 4 was having GPS accuracy issues. My error of margin was (on some occasions) 60+ meters off (on avg 25-30m) and number of fixed satellites was extremely low (hence accuracy issues). I ran a test before and after several times and with the case on my signal and GPS continually had issues. I urge people to try for themselves. Download a GPS status app (I'm using GPS Status & Toolbox from the play store), keep your phone flat and notice the difference with and without the case on. I really like this case, but I need my GPS accuracy. The phone signal drops an avg of 3 bars with the case on.

Thought putting the Zenfone 4 in and out of it would be less of a fuss. The detached back makes it more so.

It is a nice case. No doubt. Only a couple pieces of advice. 1) a guide to fit the phone in the case would be nice. It isn't as evident as one may imagine. 2) The case's metal frame weakens the phone receivers. It happened with the GPS with the phone loosing the GPS connection and tacking a long time to acquire it. We have removed the case and a using a more generic one and are not experiencing those issues
