This article is just a huge scam. I purchased the "zZjoOoj" glass screen protector from Amazon and the fingerprint reader just does not work. Is the writer lying to get Amazon commissions from click purchases?
I purchased a second glass screen protector from a different brand and it has the exact same problem. They both come with a distinguishable circle where the fingerprint reader should be. You attach the glass to the phone, then the circle becomes a smudge (tried 3 separate applications and happened to all), then the fingerprint reader simply does not work. Sure, after many retries you can get it to enroll a fingerprint, but good luck ever being able to unlock the phone with your finger.
Do NOT buy zZjoOoj nor Newspoint glass protectors, they are both garbage when it comes down to the fingerprint reader working.
