The Zerolemon I installed a month ago has the halo but has not budged since installed. I have had a Thor case on it, a Ballistic Tough Jacket and a couple of different Spigens. However I don't take cases on and off regularly which might contribute to the protector lifting for some folks. Not a matter of trying to protect the Protector in my case. I just don't take cases on and off that often as a matter of course.
I think a lot is a matter of the installation. In my case while I am not thrilled with this Zerolemon it is not coming off unless and until I have another in hand that I want to install. Once again I will be attempting to create as perfect an installation environment as I can possibly create with everything in place before I even attempt to get the screen protector that is on it off. Frankly, the halo just does not bother me nearly as much as it seems to bother some.
The only thing I can really say about the Zerolemon is that it is not a fingerprint magnet of any kind. If anything it seems to reject fingerprints. Beyond that and the fact that it seems to stay on if it is installed correctly, there is really nothing to recommend it....price I guess...it is not nearly as costly as some. Yes the S-pen works fine as does the touchscreen. But I would not have expected S-pen and touchscreen to have been an issue anyway.
