> I've broken a couple of screens shortly after a repair until I realized I needed to be more meticulous about how I glued the cover back on, and to keep it in a vice until the glue dried.

Can I ask what phone(s) you are talking about? I replaced the battery of an iPhone 7 recently, and maybe it was just early in the evolution of these designs, but putting the screen back on with the sealant ring was the easiest part. Personally found it much harder to break the adhesive - definitely the longest step, but this was my first modern phone battery replacement.

I repaired a Nokia 8.1 and a Xiaomi Mi A2 recently. I used the (commonly used) B-7000 glue for both. It takes up to 48hrs (or more) to fully dry, I didn't wait enough so I think it dried pretty loosely on the Nokia 8.1. As a result the screen broke soon thereafter. Went better on my second try.
