So somehow I managed to smash the glass on the back of my phone… think I may have stuck in my back pocket with my keys or something at some point but whats done is done…
Ordered a replacement bit of glass from a website called iParts4u… LG G5 Camera Lens and Bezel Replacement
I first powered down the phone and removed the battery (as you can on a G5)… then used a hot air gun carefully to gently warm up the adhesive holding the existing (broken) glass on the back of the phone… I used a pair of hooked tweezers to prise the glass out… if yours is just cracked rather than smashed like mine then you would need to use a plastic opening tool (like the ones I used to do my megapod) to try and hook under the edge of the glass without damaging the phone case..
Carefully peel the glass off… you may need to slide the tweezers under the glass once you have lifted it away enough to get underneath… once off I then blew the dust and broken glass away with a lens blower…
Aligning the sticky pad to the glass was fiddly especially with my eyesight lol but once done its then easy enough to stick the glass back on the phone using a bit of gentle pressure… make sure you have the orientation right as the opening in the glass is bigger for the wide angle camera than the normal camera
And done 🙂
Bit easier than changing the glass on an iPhone at least
