Replacing the front screen of the Prevail
I didn't have a way to document this so I took notes.
Galaxy Prevail screen replacement
First power down the phone and remove the battery cover and the battery.
Remove the SD card.
Remove the 6 small phillips screws on the back.a precision screwdriver works.
With a plastic pry tool( I used my smallest jeweler screwdriver) to remove the section surrounding the battery, it is
clipped in from the side.
There are only the 6 screws you took out so don't worry about hidden ones.
The PCB has a small ribbon cable attached, but it can be taken loose with a finger nail, then the pcb comes out, but has
resistance from the thin double sided tape holding the phone speaker to the front.
You will now see a small ribbon cable with an IC inline, this is the connector to the digitizer,there is a small black
retainer clip holding the cable in place.
With a straight pin or very small tool, gently pull up the clip from the black part and it will raise up like on a hinge.
Gently pull the ribbon cable out of the clip and away from the grey panel.
Remove the grey panel by releasing it from the clips on the sides. gently pry it from the side.
Now you will see the back of the LCD screen, it can be removed with care and also to be safe.
Now you have the front panel attached to the side housing.
There will be one clip at the top and two at the bottom.
I used a thin razor knife and a small flat screw driver to remove the front panel, I used the small screw driver to push the
3 clips out and the knife to pry away the sticky tape holding it to the frame. They are there for allignment.
It is secured with thin double sided tape to the frame.
Replacing the front screen
The replacement I bought had protective plastic covering the sticky on the new cover.
Remove the plastic exposing the sticky on the cover.
My new cover didn't have the grey piece of plastic behind the menu, home, back, and search buttons.
You will have to remove it and the speaker cover from the old face and add them to the new one, they come off easy.
Run the ribbon cable through the slot where the old one came out.
Position the cover and attach it to the frame and press it get it to stick to the frame.
Replace the grey panel popping it in at the sides.
Attach the ribbon cable. (note that the cable goes under the pins on the clip)
Replace the PCB and plug in the first ribbon cable at the side.
Replace the back frame by popping it back in.
Put the 6 screws back in.
Replace the SD card and battery.
PS: the cover I purchased didn't have the small grey cover for the bottom buttons or the grill for the speaker at the top.
I swapped them from my old one to the new one. This should help others from forgetting to change them and stick the face
then have to remove it to put them in.
It is very important to take note of how you remove a part so you know how it goes back in.
I had no camera to do video of this so I wrote this right after I finished and tested my phone.
I will assist as much as I can if someone needs help.
I hope this will help others in some way.
