Introdução

Use this guide to replace a cracked or faulty OLED display on your Samsung Galaxy S7.

Be aware that the video guide does not match the step-by-step guide below, it is an older edition of the guide.

The video guide recommends removing the battery, SIM tray, and motherboard. This is not necessary, but it does make heating the phone safer. This procedure is only recommended if you're replacing the battery and the screen at the same time.

This guide instructs you to replace only the display while leaving the original frame, logic board, and battery in place. Note: some replacement screens for this phone come pre-installed in a new frame (a.k.a. chassis), which requires you to transplant all of your phone's internals and install a new battery. Make sure you have the correct part before starting this guide.

If the frame is damaged or bent, it's important to replace it, or else the new screen may not mount correctly and can suffer damage from uneven pressure.

The process of separating the display from the frame usually destroys the display, so don't follow this guide unless you intend to replace the display.

If your screen is badly shattered, wear eye protection, and apply a screen-protector, or tape, to the display to help contain glass shards.

  1. Opening your phone will compromise its waterproof seals. Have replacement adhesive ready before you proceed, or take care to avoid liquid exposure if you reassemble your phone without replacing the adhesive.
    • Opening your phone will compromise its waterproof seals. Have replacement adhesive ready before you proceed, or take care to avoid liquid exposure if you reassemble your phone without replacing the adhesive.

    • Apply a heated iOpener to a long edge of the phone for about two minutes.

    • You may need to reheat and reapply the iOpener several times to get the phone warm enough. Follow the iOpener instructions to avoid overheating.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the OLED display and internal battery are both susceptible to heat damage.

    I used a heat gun and heated it a little too much. The color of the rear glass is just a sticker on a clear cover. Due to this I tore the sticker off. Now the back cover is see through, which isn’t a bad thing but the repair was for a customer.

    When using the iOpener, you may need more than 30 seconds, especially in compact or low wattage microwaves. Take this slowly, though, and be extremely careful, as it is easy to overheat your iOpener. Remember, you can always heat it up a tad more, but you cannot undo overheating it.

    I used an adjustable heat gun and set it to 400 degrees (F). That was enough to seperate the glass without having to worry about exposure times of the heat. The front of the phone was just fine. Just be ready to use a bunch of picks to slide in between because they will be needed this way.

  2. When the back panel is warm to the touch, apply a suction cup as close to the heated edge of the phone as you can while avoiding the curved edge. The suction cup will not make a good seal on the curved portion of the glass. If the phone's back cover is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.

    • Lift on the suction cup and insert an opening pick under the rear glass.

    • The rear glass can break if you use too much force or attempt to pry with metal tools.

    • Due to the curved glass, you will be pushing up, rather than inserting parallel to the plane of the phone.

    • If you have trouble, apply more heat to further soften the adhesive, and try again. The adhesive cools very fast, so you may need to heat it repeatedly.

    • Optionally, once the pick is inserted, you can add a few drops of isopropyl alcohol into the gap to help weaken the adhesive in the following steps.

    Because of the metal lip around the phone the picks were to thick to get under the glass. Couldn’t get the glue loose enough with the iOpener or the glass lifted high enough with the suction cup despite using a lot of heat and stength on the suction. Ended up having to use a thin piece of metal to get the first separaration. After that the picks are ok to use.

    • Be sure to turn on your phone and test your repair before installing new adhesive and resealing the phone.

    • If desired, you may reinstall the back cover without replacing the adhesive. Remove any large chunks of adhesive that might prevent the back cover from sitting down flush. After installation, heat the back cover and apply pressure to secure it. It won't be waterproof, but the glue is usually more than strong enough to hold.

    Much of the back part of the display was also glued to the chassis on my phone. Be very careful when removing the bottom adhesive around the capacitive buttons - I thought what I was peeling off was glue and adhesive, but in fact they were the buttons themselves. I inadvertently damaged both and rendered them useless.

    • Follow this link for a detailed screen adhesive application guide.

    • Before installing a new display, it's very important to remove all traces of the old adhesive from the frame, while taking special care to remove any small glass fragments.

    • After removing all traces of glue and glass from the frame, clean the adhesion areas with 90% (or higher) isopropyl alcohol and a lint-free cloth or coffee filter. Swipe in one direction only, not back and forth.

    • This helps remove any remaining adhesive residue and preps the surface for the new display.

    • If the frame is bent, or if any glue or glass remnants are left behind, the new display will not mount correctly and may be damaged.

Conclusão

To reassemble your device, apply the adhesive to the rear cover and follow these instructions in reverse order.

The screen replacement went smooth. I just wish it included the adhesive. I didn't see the note where the adhesive needed to be ordered in addition to the screen. Otherwise everything went well.

Thanks

For the price of the screen, I can replace it in a Samsung repair center...

I just need to replace the glass, not all of the AMOLED touch screen... :-( Sorry but this didn't help me.

How much cost u paid to service centre for original display for samsung s7

Durgaprasad -

You can not replace just the glass without special equipment (hot plate, laminator etc.)

Dinan Blueje -

I'm wanting to help my friend do this but I don't have a heat gun. Would a blow dryer work to loosen the glue or does it need to be hotter? He got a quote for 200 from a shop to fix it but they said it takes a month…lame! I've replaced screens in many tables and phones and I have all the necessary tools other than the heat gun and the replacement screen components obviously.

Adam Bacon - Responder

@Adam Bacon Heat guns are quite inexpensive. The model she uses in this video runs about $20 or less in most shops. A blow dryer may work, but it’s difficult to say for certain. The adhesive Samsung uses is pretty robust. If you find yourself fixing a lot of devices you should really consider investing in a heat gun.

E West -

I did this repair. A heat gun isn’t really hot enough to remove the screen without destroying it. A hair drying isn’t going to touch the glue.

I just want to add that if you only need to replace the glass, this is not the guide for you, and the difficulty rating is a 10 of 10. What I would do to replace just the front glass, is to avoid all these steps, and remove the glass from the front. Do not attempt to remove the AMOLED screen, it will shatter in the process of removing it. You will notice in this video, the screen shatters in the bottom left of the phone, behind the glass.

The other issue is that the glass is laminated to a filter, which is backwards from many screens, where the LCD panels are laminated to the filter, and the screen floats. When you buy a replacement glass, you will need one that has the laminated filter attached, or you will need to figure out a way to separate the two pieces. (I could not).

armand what did you use to remove the back, i’ve tried the hair dryer with no luck. Thanks;

I would also like to point out that both the front and back glass are extremely brittle. If you broke your glass, because the phone landed on its side, then check for spurs. The smallest protrusion will shatter the glass while applying pressure to seal the adhesive application. I had the tiniest of a protrusion, and the back glass exploded. Thankfully, those are cheap.

Thank you very much for good instruction

Guide help, the included heat pack did not. I ended up buying a heat gun instead. Took my time instead of rush it like some places do or they would just replace your phone all together, which is not what you paid for really. Def was tedious.

Quang Pham - Responder

Really a good guide!

Maybe it could be cool if with the display assembly comes also the rear glass.. because there is a very high probability that it will damage quickly (during the opening)

So, for those who are going to repair their Samsung Galaxy S7.. just be careful with the back glass!

Thank you all ;)

Running into bit of an issue, my screen is broken. At the moment I’m finding ways to turn it back on, restart, hard reset and etc. Nothing that will actually turn it all the way off so I can begin taking off the back panel.

Austin Pimentel - Responder

The safest method would probably be to let the battery run down, to ensure it doesn’t turn back on and short-circuit something. Good luck!
