Hi,
A couple weeks ago, my OnePlus 7 fell on hard concrete as I was recording a voice message, so it was quite long fall. I'm using a Dbrand screen protector which did its job so the screen has no cracks on it. However, I noticed a few days later that the screen is no longer properly attached to the rest of the phone. It's only attached by the flat cable so it kinda falls when I hold it while laying on my bed. Other than that, it's working properly but it's still inconvenient.
I am not sure if this can be fixed at all and what the issue is. It smells like glue, so I would like to know if it's supposed to be screwed back, if something needs to be glued back, and if it can be fixed.
Thank you.
