I've had various mobiles for many many years (I'm 64) and have always used a case and a protector for the screen, and never had a damaged phone. I order all three at the same time and don't use the phone until everything has been delivered.
The edge presented a problem that we're all familiar with so I went for this one despite the £18+ cost.
S6 Edge Plus Screen Protector, JETech® Full Screen 5.7" Premium Tempered Glass Screen Protector Film for Samsung Galaxy S6 Edge Plus
Everything was great, easy to apply, no bubbles and looked great..... then I fitted the Otterbox case! Disaster, cracked protector and £18+ down the drain.
Currently, and for the first time ever, I'm using the phone with no screen cover. I feel naked, but don't feel like risking another glass one.
Any answers welcome though - who's got a glass sceen cover PLUS a case?
