I removed my previous ZAGG Glass Screen Protector from my iPad Air 2 for two reasons: increased screen glare and lowered TouchID efficiency. In response, ZAGG sent over another set of their screen protectors: another Glass with a different “Omega” Home button cut-out, and their HDX protector, which claims to add great impact protection.
I haven’t yet installed the HDX, but I have spent the last few weeks with this newer Glass protector. The button cut-out on my previous Glass was circular, which made the Home button harder to press and I suspect it kept my finger just far enough from the TouchID sensor to affect accuracy. I’m happy to say that the new cut-out, which leaves the lower portion of the Home button exposed, no longer affects TouchID performance. I can reliably unlock my iPad Air 2 with my thumb, and I think that has everything to do with my finger sitting closer to the sensor.
As for the glare, I do think it’s still present, but it’s not a showstopper. The naked Air 2 screen still has glare, but reflections simply don’t look as bright as they do with a ZAGG Glass installed. I tend to run my iPad at about 30% brightness most of the time, and I find that’s enough to outdo any of the ill effects of an extra layer of glass over my screen.
So does this altered version of the Glass change my recommendation? Actually, yes. I do think there’s a tradeoff in glare for installing a ZAGG Glass, but it’s a fair one if you want an added layer of scratch protection that doesn’t affect the clarity of your screen (in the way that matted screen protectors can). There doesn’t seem to be a way to check whether or not the Glass will have the Omega cut-out, but their support seems good enough that you could contact them afterwards if you end up with the previous circular version.
