Introduction

Use this guide if your new display assembly comes with the front-facing camera, earpiece speaker, and LCD shield plate already installed. You'll simply remove the old display assembly and transfer the home/Touch ID sensor to the new display assembly.

If your replacement display does not include those components, you'll need to remove them from your old display and transfer them to the new one. We'll have detailed guides for this process in the near future, so stay tuned.

In either case, the original home/Touch ID sensor must be transferred onto the new display in order for it to function.

Opening the iPhone 8 will damage the waterproof seals on the display. If you do not replace the adhesive seals, your phone will function normally, but will no longer be water-resistant.

As of May 2018, replacing the iPhone 8 display disables the ambient light sensor, even when using original Apple parts. Consequently, auto-brightness and True Tone functions won't work with replacement displays. It's believed this is due to a bug in iOS 11.

Video Overview

Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

Apply a suction cup to the lower half of the front panel, just above the home button. Be sure the suction cup does not overlap with the home button, as this will prevent a seal from forming between the suction cup and front glass.

Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case. Insert an opening pick into the gap. The watertight adhesive holding the display in place is very strong; creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, apply more heat, and gently rock the screen up and down to weaken the adhesive until you create enough of a gap to insert your tool.

Slide the opening pick up the left edge of the phone starting at the lower edge and moving towards the volume control buttons and silent switch, breaking up the adhesive holding the display in place. Stop near the top left corner of the display. Do not try to pry the top edge of the display away from the rear case, as it is held in place by plastic clips that may break.

Re-insert your tool at the lower right corner of the iPhone, and slide it around the corner and up the right side of the phone to separate the adhesive. Don't insert the pick very far, or you may damage the display cables along this side of the iPhone. Insert it only a few millimeters, or about the width of the display bezel.

Open the iPhone by swinging the display up from the left side, like the back cover of a book. Don't try to fully separate the display yet, as several fragile ribbon cables still connect it to the iPhone's logic board. Lean the display against something to keep it propped up while you're working on the phone.

  • Remove four Phillips screws securing the lower display cable bracket to the logic board, of the following lengths:

    • Two 1.3 mm screws

    • Two 2.8 mm screws

  • Throughout this guide, keep careful track of your screws so that each one goes back where it came from during reassembly. Installing a screw in the wrong place can cause permanent damage.

  • Remove the bracket.

Not Y000 this time haha

Use the point of a spudger to pry the battery connector out of its socket in the logic board. Bend the battery connector cable slightly away from the logic board to prevent it from accidentally making contact with the socket and providing power to the phone during your repair.

Use the point of a spudger to pry the lower display connector out of its socket. To re-attach press connectors like this one, press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is even slightly misaligned, the connector can bend, causing permanent damage.

Use an opening tool to pry under the left edge of the home button cable connector to disconnect it from its socket. If the entire connector begins to flip up without separating, press down on the cable at the top edge of the connector with the flat of your spudger, while simultaneously prying up the left edge of the connector. Be very careful not to damage the cable or connector, or you will permanently disable the sensor.

So once the adhesive seal is broken, obviously the warranty is done for, but is there any way to restore water-resistance?

Chris - Reply

You need to buy a special waterproof glue for it.

Ou Hiroshizon -

And do you just wing it for the front camera, proximity sensor etc ?

This guide assumes you’re replacing the entire display assembly, with those parts included. If you bought a bare display then yes, you’ll have to transfer those additional components over, and that’s beyond the scope of this guide—although as mentioned in the introduction, we’re working on adding guides for those additional components as well.

I’m looking to replace the back glass as well. Any advice?

Trey Granger - Reply

This video shows what’s involved. Basically, remove ALL of the internals from the phone, and then painstakingly heat + pry the glass shards off the back of the chassis. The metal camera housing has to be forcibly twisted out and replaced. It’s a very difficult repair, with a high risk of damage to your phone (and a high risk of injury if you don’t wear gloves and safety glasses). I’m not sure the phone will ever look 100% again or retain its IP67 rating. My advice would be to wait until a full enclosure replacement part becomes available with the glass preinstalled, and then transplant your entire phone into that. Meantime, the glass itself is purely cosmetic, so I’d suggest covering it with a custom skin or wrap. Of course, the final option is to pay Apple $349 USD for an “other damage” repair and make it their problem (they’ll swap you out for a new phone and yours will go to a refurbishing center somewhere).

Jeff Suovanen -

wait a second… Are you saying that when we change the screen it is also necessary to change the front camera?

Caio Antonius - Reply

@eitantonius A lot of new screens come with a replacement front camera already installed. They cost a bit more, but make the job easier. You can save a few bucks if you buy a stripped-down display, but you’ll need to go through some additional steps to transfer the original front camera (and a few other components) from your broken screen to the new one.

I cracked the camera glass (housing) on the back of the phone. Is it possible to replace without replacing the entire back of the phone/case?

May I know any way to fix the auto-brightness issue after screen replacement?
