Okay, so my dad recently bought me a Kindle Paperwhite and a plastic film screen protector for it. I took the Paperwhite to a shop and a salesman applied the screen protectora for me. There were no visible fibers, and no bubbles underneath the protector then. A few days later, I noticed there were a lot of fibers underneath the screen so I took off the screen protector and reapplied it. No bubbles, No fibers then. And now, there are fibers underneath again. I don't wish to take the protector off again as the screen protector might get damaged; how do I fix the problem? Will changing to a glass protector fix it?

Thanks for reading my post! I hope the post wasn't too long.
