I have recently bought the zagg high definition invisible shield for my nexus 5 and got it installed for me at futureshop. The man didnt tell me whether or not to keep a case off of it or not to use for 24 hours. I just figured i should keep the case off so i have been leaving it off for the past few hours. But as soon as i got my phone i started to use it and have been since will using it immediately after getting it installed effect my nexus 5 or the screen protector? Thanks
