Introduction

This repair is not that hard is very simple the only tricky part is taking of the back cover without breaking

Changing the samsung galaxy s7 screen but in same time try save the old screen so you can sell it

Heat the back of the phone to melt the adhesive holding the back plate on. I use an electronic heating pad, set to 60° Celsius. You can also use a heat gun, but I do not like using them. Be extra careful if using a heat gun, as they are easier to burn yourself with, and holding one over a phone for even just a little too long can damage it.

Use a suction cup on the bottom half of the back plate to begin to lift the bottom edge of the plate up, being careful not to apply to much pressure. Once you have enough of the back plate lifted to fit a guitar pick, insert one underneath. Slide the guitar pick around the entire edge of the phone to break the adhesive. Remove the back plate.

Using a Phillips #00 screw driver bit, remove the 11 screws holding the plastic covers, loudspeaker, and NFC antenna on. Using a guitar pick to break some light adhesive, remove the top two plastic plates, and the NFC antenna. NOTE: If the adhesive is too strong, try applying more heat.

    • Be extremely careful around the sides and bottom of the phone. If done incorrectly, you may damage the screen flex cable, or the softkey flex cables.

    • Also be careful around the LCD. Make sure the guitar pick slides BEHIND the LCD, not in front of it, and that you have the guitar pick as flat as possible.

  • Remove the screen.

Can just the glass be replaced do is it fused together somehow?

Edward Stallard - Reply

it could if you get the lcd out with broken glass out one piece then using heat plate separate the glass very thin so it be hard to save lcd

The Eternal question: is it still waterproof after screen replacement?

Grant Ormsby - Reply

no it wont because you will break the seal that originally came from samsung

Brian -

Is it still water resistant

Caleb Phillips - Reply

no it wont be water resistance any more

Appreciate the effort, but this guide is severely lacking. There is little to no guidance about it.

sorry this my first guide and i did it so other repair people get idea because ifixit at the time had no guides at all so that is why i did a quick one as i was repairing the phone

Brian -

i know all i tried was just to help out i did this guide as i was repairing the galaxy s7 for the first time myself.

Brian -

I accidently cut the ribbon cable to the digitizer. ...ouch. Do you sell the digitizer assembly for the Galaxy S7 edge as well as the sealant for the back of the phone like you do above for the regular Galaxy S7 for 169.95 as well as the rear cover adhesive for the S7 edge...probably same adhesive. I read many article and if I had followed your article I would not have cut the ribbon cable....Good article. Thank you, rexblisard@yahoo.com

Sorry but this has got to be THE worst guide I've ever seen! All it does is state the obvious! Why do I need a guide for that? :(

Watched the video and I am wondering, why can you just replace the screen with out taking every thing out of it. Couldn't you just snap the screen connector back into place. Just asking.

Bryan - Reply

Wondering if this can be done then the phone traded back in to the mobile provider without anything being noticed...

WesG - Reply

they dont really check the phones if the screen has been replace all they care about is working and they just wanna make anther sell to you so no worries

Brian -

Omg. just say thx for the effort and the guide...he wasted hes time..if this guide doesn't help you..then take ur phone to a repair shop..if u already repaired ANY waterproof mobiles..u would know how to open it and deal with it..and this guide would only help to identify components and avoid posible mistakes like cutting a ribbon or damaging something inside...

I really thank you for your time....i just got mad when i saw ppls coments...

thank you for understanding

Why take the back all apart if only wanting to change the screen???? Can't I just take the screen off an put new one on??? Really don't see the point of taking back off and a few boards as well ?

Phill Mcgowan - Reply

because the cable connects in the back so if you don't open the back you can not plug the lcd cable with the motherboard

Brian -

I was hoping for a guide not just "remove mother board, remove screen, clean"

Lee - Reply

they have better guides in youtube feel free share the link here

Brian -

Lol the one guide on iFixit where OP doesn't completely hold your hand and everyone gets all upset.

I think it was a dope guide. Helped me catch all the tiny ribbon cable connections - I totally would've missed one without this.

Although, yeah, it seems like you really only need to disconnect the display cable from the daughterboard to get the display off.

thank you i hope it was some help

i apologize for asking a repeat question but I do not see answers - Is it possible to replace just the glass for this phone? i have cracked glass and a working digitizer. another electronics outlet sold me a glass replacement kit but no instructions. All the vieos i’ve been watching and the forums/guides I’ve read all discuss replacing the entire front(digitizer/glass).

is it possible to replace just the glass? if so, can it be done without removing all the parts from the back? since technically I won't need to plug in to the motherboard?

Michael Kresge - Reply

Its possible but very hard to do i tried few times just changing the glass i end up breaking the screen but on youtube you have some people that are able remove just the glass with bussiness cards.. chances are 20% can get just the glass out withought breaking lcd unless you have freezing mashine thats a different story..good luck
