Nothing you can do about that other than buying the plastic thin type of protector instead. Rigid glass will not bend at the edges to stick to the screen. Annoying as many phones do this now Samsung S7 (non Edge version), Honor 9 Lite as well. Any screen protector that is not rigid should be fine. THe downside is these are pain to put on without getting air bubbles though.
Please any screen protector advice would be appreciated.
Don't mean to pee on the OP's chips but these have been this price at Argos for weeks, amazed it hasn't already been posted. I did actually buy one but took it back due to the fact that mobile data point blank refused to work. If you're thinking of getting one: Battery life was pretty awesome, screen very nice (although I don't like 18:9 it must be said), it was fairly quick and the software had some nice little extras (funky live wallpapers, screen/sound recording just two examples). The notification LED was almost totally useless and IMO fingerprint scanner too high on the rear, very slippery in hand too. Still worth buying? Absolutely!
I even used one before. Great product in this price slot
There are dozens of reviews on other sites and pretty much all claim it is IP67 eg: https://smartphones.gadgethacks.com/news/meet-honor-7x-huaweis-new-premium-budget-phone-0181257/ http://www.androidpolice.com/2017/10/11/huawei-announces-honor-7x-china-189-display-aluminum-chassis/ https://www.androidauthority.com/honor-7x-806638/ http://www.androidguys.com/2017/10/13/is-it-worth-the-upgrade-honor-7x-vs-honor-6x/ There are dozens more - its unlikley they are all wrong.
