Glad you got it fixed! I'm not sure if being over-tight could really be the issue as the PCB should just be tightened down onto plastic standoffs in the case.
The bluetooth aerial is in the plastic case though, connected by that sprung plastic contact, and I wonder whether the contact can corrode slightly and lose contact. I think in a lot of cases just moving the PCB around and tightening up should be enough, but it's a pain that it's so difficult to do because of the LCD.
And yes, that BEST B-7000 glue looks like it'd be perfect! I'd never seen that stuff before
