On my old iphone 4s I never used one and it held up fantastic. I got a screen protector with my otterbox case for the one and unsure if I really need it. how many of you use a screen protector on your htc one?
You will get mixed answers. Some will tell you these screens don't scratch, others like me will tell you they do scratch just not easily. To avoid micro scratches and potentially something worst I use a screen protector.
I didn't use one until I saw tiny scratches on my sister's one. Then she and I got ghost armor screen protectors at a local mall. My phone didn't have any scratches but hers did.
If you have ti even think about asking....Just do your self a favor and get one. I have a ZAGG IS on mine and I love it so far. Worth the small investment if you wanna sell it later or keep it in perfect shape for years to come.
