Step 1: Preparing the Phone or Device for Repair
Before doing any repair work on a phone, switch off the phone and take out the battery. It's also a good idea to take precautions to prevent the broken glass from shattering when the old screen is removed from the phone. Apply Scotch tape over the broken glass can help to hold the shards together when the glass is removed.
Step 2: Loosening the Phone Glass
The glass screen is held in place by strong glue. Apply heat to the glass, using either a hair dryer or a heat gun, to melt the adhesive so that the glass can be removed. The heat must be directed at the edges of the glass until it starts to loosen. Once the adhesive loosens, slide the plastic prying tool (or playing card) between the top of the glass and the frame of the phone. Next, take the wire or floss and slide it into the gap that the plastic tool opens up. When the glue has sufficiently softened by the heat, the wire will easily slide from the top of the phone to the bottom, separating the glass screen from the LCD. Insert the picks as you go to keep the screen separated. This may take a few attempts so be patient.
Tip: Do not force or pry your screen apart. Heating the adhesive allows the screen to be separated. Using extreme force to pry the screen off can damage LCD and digitizer. A Full LCD Touch Screen is the easiest DIY repair.
Step 3: Cleaning and Preparing the LCD
Lift away the glass screen, revealing the LCD beneath. You will need to clean this display with a microfiber cloth to remove any dust or traces of adhesive. Once the LCD is completely clean, strips of double-sided tape should be applied to each edge. This tape will hold the new glass screen in place.
Step 4: Applying Adhesive
You need specialized double-sided adhesive for the repair. This is very thin and fits perfectly around the edge of the replacement glass screen. If you are using the 2mm adhesive, just pull off a each strip with tweezers and cut if need and apply until all edges. Also apply strips to the middle of solid parts of screen at top and bottom. This tape will hold the new glass screen in place.

Note: Replacement screens can be secured using adhesive tape strips or UV glue. While the UV glue provides a stronger, longer lasting bond, the adhesive strips are a much safer solution. Use of UV glue requires a curing lamp and can result in damage to a device if too much is used and it seeps into other parts of the phone. We don't recommend glue for first time DIYers. UV glue and curing lamp can be purchased separately if desired.
Step 5: Fitting the New Glass Screen
The final step in this repair process is to remove the protective plastic covering from the new phone glass screen and place it onto the phone. Press down firmly on each edge of the screen can help to create a firm seal between the glass and the adhesive tape.
