Insert a plastic opening tool between the midframe and the display assembly. Work the plastic opening tool around the perimeter of the phone to break the adhesive. This adhesive is relatively weak, so no heat gun should be necessary.

  • Be careful to not separate the front glass panel from the rest of the display assembly, as it is still held together with adhesive.

I managed to kill my LCD with this step. Warrants caution.

It always will. The lcd is the thickness of a credit card and glued to glass

I also cracked my screen with this method ,not to be outdone I bought another phone for the screen .this time I used a thin guitar pick which I ran along the edges and around the phone carefully , it took a while but eventually worked the screen loose ( the glue area is small but still strong as I learned the first time) any way when the screen is loose enough , make sure the tabs on the inside cover are also loose (using the pick) I was able to then pop out the screen and replaced the mobo I have a nice new phone now ! Bottom line is don't pry on the screen it will crack loosen it completely and it will pop out nicely . Good luck .

"This adhesive is relatively weak, so no heat gun should be necessary." I don't agree with this statement. It's very hard to separate display from midframe.

This is not hard to do, but it is dangerous. The author is correct, no heat gun is necessary but it's easier with a heat gun or low or a hair drier on high. Don't use a metal blade, only use a guitar pick or plastic spluge. Be patient and do resist any temptation to pry *deeper*. Just keep prying shallow and horizontally. You may have to go around the perimeter several times but you will succeed.

As soon as you rush, decide you have to pry harder or let a tool go a millimeter or two *deeper* that is what will kill your LCD.

Entirely doable if you are very cautious.

I meant to add.. there are two ways to kill the LCD or possibly crack the glass. By going too deep in the seam. So stay shallow. But you can also damage the LCD by putting too much sideways horizontal stress on it too. So it helps to keep moderate pressure down on the top of the phone so that most of your prying sideways force goes towards deflecting the bezel outward and thereby dislodging the adhesive seal. So "pinch" the phone by holding the top and bottom between your fingers of one hand. Or set the phone on a flat surface and press down on the top (glass) of the phone moderately to try and keep the glass and LCD sandwich in place while you pry as gently as possible sideways and outward to dislodge that adhesive seal.

Use a plastic opening tool to loosen the clasps around the battery housing.

Push on the battery housing to separate the midframe from the display assembly. You will have to apply a reasonable amount of pressure to separate the two parts. If your new midframe does not come with a headphone jack assembly, you'll need to transfer the one from the old midframe into the new one. It can be pried loose with plastic opening tools, as it is held in place with several plastic pins.

If you want to break the LCD or if it is already broken, poke both your thumbs into the battery pocket as shown in the picture. This may snap off the back, but it will also crack the LCD. The better way is to put your right thumb into the top right corner of the battery well and your left thumb on the SC card slot, then hook your fingernails on the top corners and side edges of the rear housing and push gently to separate it from the midframe.

Remember, the LCD hinges at the top, the rear housing hinges at the bottom. Once you see how the charge port fits into the recess at the bottom of the rear housing, you will understand what I mean.

This Note 4 rear housing fits tighter than previous Samsungs such as the S3 & S4 where you can take out the screws and then pop off the rear housing easily with your fingernails. Be very careful around the touch button flex cables at the bottom or be prepared to replace that assembly. It is cheap, so you may want to go ahead and order that when you get an LCD assembly.

Thank you, very helpful in my swap out of the assembly. I also had to remove the headphone assembly and reinstall it into my new mid-frame. I added a step 5 to this user guide with a new image of the part that must go into the replacement mid-frame.

I have attempted twice to remove the hear housing without breaking the LCD. And i have been working on phones for 12 years. It will break every time this should not be attempted unless the LCD is already bad.
