At the same time, superglue's brittle, meaning if you handle objects that were glued together, they're eventually gonna come apart in your hands. There's a reason smartphone screens use some special mystery glue not CA.
The problem with acetone is that you can't really get the solvent to the surface that's glued, since that's often inside the object, so it's really tricky to use. It's also toxic and attacks basically everything that's plastic or painted, resulting in a lot of damage.
AFAIK, smartphone glues tend to be acrylic adhesives, which are just as brittle as cyanoacrylate. They get around this by not bonding the screen directly to the chassis with the glue, but having the adhesive carried on tape.
Superglue doesn't work on Teflon, or most plastics you want it to work on. Wanting to glue plastic things together isn't exactly a niche need. Being able to remove that glue with hand sanitizer would be wonderful.

As a chemist it’s a highly polar, very high boiling point solvent that is the “go to” when you can’t find a solvent your reactants dissolve in.
Acetone is less polar, more chemically reactive and lower boiling point. It’s rarely used as a reaction solvent due to its reactivity, but it is common in crystallizations.
Both are quite non-toxic (your body makes small amounts of acetone!), but I recall a cancer risk with high exposures of DMF (the example was tannery workers who sprayed it without any safety gear and got soaked).
Acetone only dries out the top skin layers, which immediately triggers a healing response and accelerates the shed cycle. Dermatologists use acetone prior to skin surgery to speed up the recovery.
It’s extremely safe. Your body naturally creates it and you exhale and piss it out every day. If you are having any long term health issues from exposure then this may indicate that your immune system is seriously compromised.
