I'm surprised how many people still use screen protectors, my 2 year old phone looks spotless majority of the time unless under the brightest of light and stupid angles with the screen off and even then I really have to look hard for the few micro scratches it has
And if you had a screen protector you would not have them few micro scratchesand when it comes time to sell you can say the screen is spotless and have better chance of selling
Its a definite no from me, I just keep my phone in a separate pocket to keys and coins etc. and never get any scratches. Screen protectors are horrible for the reasons you describe, I'd really rather not have one. I guess you can get some pretty good ones these days (apart from with curved screens like you) but it always seems odd to me when somebody has a nice phone and it looks terrible as they have an old screen protector peeling away at the edges.
