ok so scratches doesn't void the one year warranty right? the reasons i don't want to get a screen protector are because it makes finger swiping feel different and i've heard problems where it interferes with the sensor. makes the screen feel sticky plus if it's not put on relatively even on all sides it bothers me because i have this thing about being even. >_<
the reason i want to get one is because i don't want scratches. it seems people are getting them with this screen even though i never got one with my razr maxx. i just figured screens have improved to the point of no scratches so i haven't seen one in any of my last 3 smartphones (htc incredible, galaxy nexus, razr maxx), all of which never had a screen protector and have fallen on the ground face down. i had a screen protector on my original droid and it felt tacky at times and eventually the sides started peeling. i eventually took it off and never got a scratch on it.
- No, scratching the screen won't void your warranty. At least, to a certain extent. I guess they could say that numerous scratches constitutes as abuse.
- I feel as if glass has actually degraded over the years... the original iPod touch's screen was impervious to scratches, for some reason. You could always find it online and everyone would say "back is scratched, but screen is perfect". Since then, though, glass seems to always be prone to scratches.
- Just have someone install it who knows how to install it, and you won't have an issue. Yes, there will probably be cutouts for the sensors and possibly the camera, so it won't be a completely flat screen. Depending on which kind you get, the texture of the screen should not feel too different (but that will vary person to person). I'm using the Verizon protectors, and I don't think they're that good compared to better brands, but it's manageable and haven't had issues with it.
