A:Answer I'm unsure if it will work after using liquid glass, I'm not familiar with liquid glass protection. However, this particular tempered glass protector is not working well with the fingerprint sensor for me. It is difficult to save prints, frequent errors, and once I get them saved, it takes many tries to recognize them (even saving multiple ones and using different fingers), and doesn't work at all at least 50% of the time. It does hold smudges, but even cleaning the screen doesn't help much. I had a thin film protector on my last phone (came with it as a promo) and that worked well for over a year before it started to peel off, fingerprint sensor worked fine. My phone doesn't take a lot of abuse, I'm not particularly clumsy or rough with it, but it held up well. It was dropped a handful of times and no screen damage. Not sure that it would've damaged even without the protector. My 17 year old son has the same configuration, and his screen has also sustained no damage. Hope that helps you some, even though it doesn't exactly answer your question.
