  • Remove the nine 4.0 mm Phillips #00 screws securing the midframe to the display assembly.

Edit Step 7  ¶

Edit Step 7  ¶ 

  • The midframe is secured to the display assembly by several plastic clips behind the chrome bezel of the midframe. The next few steps will guide you through separating the clips to free the midframe.

  • Starting on the volume button side of the phone, insert your plastic opening tool between the chrome bezel around the display glass and the larger chrome border piece. Look for the seam between the two.

  • Slide the opening tool along the seam, separating the plastic clips as you go.

  • Be very gentle whilst prying, and pry only enough to separate the plastic clips—there are several thin points in the midframe bezel that may crack if you bend them too much.

Edit Step 8  ¶

Edit Step 8  ¶ 

  • Continue prying around the corner of the phone.

  • Slide your opening tool along the seam between the midframe and display along the bottom of the device, releasing more of the plastic clips.

Edit Step 9  ¶

Edit Step 10  ¶

Edit Step 10  ¶ 

  • Continue sliding the opening tool around the top of the phone, releasing the last of the clips and freeing the midframe from the display assembly.

  • At this point, you may want to run your plastic opening tool along the entire perimeter of the device again, to make sure you've released all of the plastic clips.

Edit Step 11  ¶

How much cost will be on replace a midframe

Hiren pedhadiya,

I'm seeing midframes available on Ebay for around $10.

On my phone, there was another clip holding the white midframe to the battery compartment, in the middle of the top edge of the battery compartment, near the battery contacts. If you don't release that before removing the midframe, it is easy to break.

Just to be sure does the rear frame referred by etradesupply is the same as the middle frame? I' planning to refurbish the side panel because of the dents and scratches but I just want to make sure I'm buying the right thing. The etradesupply referring the housing as rear and front housing so Im not sure which one correspond to the middle frame. Below is the link to the website http://www.etradesupply.com/oem-samsung-...

My Sprint S4 was slightly different then the one pictured above but I just completed this repair in under 10 minutes.. It would have been slightly quicker but fooling around with those little screws can be irritating if you have big hands.

Michael Willis, · Reply

Just did this on my S4. Instructions were extremely helpful, but I had to remove a screw (step 10.5?) to remove the upper display assembly bracket. Other than that, flawless! Thanks!

The 3rd image of the 11th step shows that when the midframe is removed, some parts come along with it (at the bottom part of it). What are these parts? should they be removed too and placed in the new midframe? Are they easy to remove?

Chris, · Reply

Replacing the S4 advance display, I've broken the plug on motherboard of the antenna, which part should I replace now ?

Second question, when display replaced, the "home" buttton was working just as the "return", did I make a wrong thing ? (perhaps ending the daughterboard) and what is the countermeasure ?

My model had an antenna connection next to the usb board connector in addition to the antenna connection near the display cable connector.

Drew, · Reply

Same as Drew. My model has two antenna connections. One as shown, and one on the left side of the motherboard.
