Back panel glass replacement problem due to camera bezel (telephoto)

Finally kinda found by myself with help of somebody. hat thing is kinda disturbing, the glass backpanel that comes from the factory goes underneath of each of this aluminium rings. When you break the glass, two lenses (but telephoto) are made with an inner ring made of aluminium also, and they are not mofing so freely. But telephoto lens do not have same logic.

I do not know if this phone was already repaired before, but if it comes from the factory like this, i can see absolutely no logic in there. So i just put some glue underneath that aluminium ring, and glued the new back glass.

The thing is, that replacement backglass, have larger holes for lenses (not like the factory one that goes underneath the aluminium cache). And then you are new to these repairs, you cannot understand it, and you're stumbled.

Hope this will help somebody
