I replaced my glass on my iPhone 5c. After I was finished I noticed I had adhesive leak in between the the digitizer and the LCD screen. Everything still works but its very annoying. Is there anything I can do other than complete replacement of the LCD, Digitizer and Glass?
not really, besides going at it extremely carefully with a small scalpel blade perhaps? otherwise you’ll have to open it again.
What you are talking about it actually in the backlight. There is a couple different options for fixing it. The first option would be to completely remove that backlight, cable and all from that assembly and solder on another, iPhone 5 backlight might work, not sure. Your other option, if soldering is out of the question, would be to remove the film and filters from an iPhone 5 backlight and place on the 5c LED strip of the 5c backlight. Be careful with the LCD tho, expensive stuff.
