Can Liquid screen protector be applied to the back of a phone

Question

This is more of a hardware question...
I got my LG V30 recently, and after a few days of usage without a case, I noticed I got a feel minor scratches, and one bigger one.



My question is this? Can I apply a liquid glass screen protector to the back of my phone too, to add some protection, qnd cover up the scratches I made.. Would that interfere with things like wireless charging or NFC?



Thank you in advance!

Answer

A screen protector, except a minority of extreme ones, don't interfere with any electric parts of your phone. It doesn't even contain any metal, usually. So there's no way that it can affect your mobile signal, NFC and blah blah blah. Its only use is to protect surfaces from scratches.
