Unfortunately what's in the subject happened and I've been scouting youtube videos and forums on how to fix it. I'm now coming to ask for your expertise, experience and opinion to fix it.
The touch screen is working fine and the colors in the LCD are fine as well, so I assume the only thing that broke was the glass. This glass part is very cheap (around 10x cheaper) than the all screen body, so I am more inclined to try to fix the glass only,
On youtube there are a few videos on how to change the screen of a Lumia 640, which is pretty straigh forward, but there are none of how to change the glass only (could only find for Lumia 920).
My understanding of the daunting task ahead is that the glass is glued to the screen, instead of the frame, which makes the repairs process more complicated and prone to issues.
What is your advice on this?
