 I've had my phone for 3 years now and I need to use screen protectors (here in Brazil it's kind of the norm), but as a perfectionist, I get anxious over misalignments, hair under the protector (even if it's on the edge and tiny), a scratch (which isn't even from the protector and I don't remember how it ended up on my phone), and halo effects (although that one was fixed using olive oil)

I can't replace the protector because parents and I'll only be able to have a new phone when I turn 18 (I'm 16, 17 next year), so I have to "get used to it," but I can't.

Any help?
