Super glue can be softened using a proprietary solvent BUT this may also met the plastic of the phone!
However, it also softens with heat. Wearing gloves, dip a dish cloth into almost boiling water, ring it out so that it is damp (and still hot) and sponge down the phone surface until the glue comes off.
DO NOT scald yourself (use thick rubber cloves) and DO NOT soak the phone.
If you want to get it of you can use nail vanish remover.
You get get super glue romover and let it dry and then try it
How do you get super glue off your jeans?
Try Goof Off, it softens Super glue so you can pick it off.
Acetone or Goof off will soften super glue when rubbed on it .
I wouldn't recommend it as super glue is a cyanoacrylate. Some super glues are used for sealing wounds but they are different to the super glue you by off the shelf at a hardwear store.
a scrubber
Nail polish remover will dissolve super glue.
Depends what kind of glue.-Name your glue-
You cannot get super glue off many porous or soft fabrics. It may be scraped off many shiny hard surfaces with a razor blade.
Super glue or crazy glue is best.
You cannot remove super glue from most fabrics without damaging the fabric.
Use Goof Off to soften the glue, then try to rub it off with a rag.
