I was given a mobile phone, my first smartphone, with a case and a protective glass plate on top of the screen which got water under it so I carefully peeled the glass protective plate off.
The "glue" is only on the top and bottom of the 6 inch long phone.
What glue is it? When I removed the protective glass using my fingernail to peel it off gently, I let it dry which solved the water under the glass problem (and the water inside the protective glass made a fog like that inside of a double pane window that cleared up after leaving the glass in the sun for a day).
The glue is no longer sticky at the top and bottom What glue can I use to put the glass back on and have it stay on normally?
