Does iPhone 5c need glue
I have an iPhone 5c and was wondering if I can just use superglue around the edges of the top glass of the phone instead of using the special glue all over
no it doesnt it uses screws
I'm assuming you're talking about replacing the glass screen, and then just glueing it to the frame instead of using LOCA glue over the LCD. Technically, yes you can do this, but it will not look good or be as responsive as it should, and I would definitely not recommend it.
Either buy the full assembly with LCD attached, or take it to a professional. You will be much happier with it.
