Sostituzione display Samsung Galaxy S7

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.

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.

Use a heat gun or hair dryer to soften the adhesive to remove the back cover. The Iopener that you heat up with the microwave takes a very long to accomplish the same task.

Keep the heat gun in motion at all times and check the surface temperature of the phone with your hand every few seconds to ensure it does not overheat the plastic and glass and electronics. Use several blue guitar picks to brake the seal of the cover once you have softened the adhesive and popped the seal initially with the suction cups.

Apply heat with iOpener/blower or the isopropyl alcohol on the adhesive you want to remove.

I did not and noticed I peeled off pieces of the paint coating from the cover glass together with the adhesive.

They made a typo I think its supposed to say 1.5 millimeter instead of 3.5 millimeter.

QA sticker over screw on my model (2018). I advise you delicately remove these with something sharp, from the center of the screw outwards. If you stick the screwdriver straight in, the sticker will jam up in the head of the screw and make it much less likely to get a good grip on the screw as it turns, causing it to slip and strip the screw head.

To me, it seems hard not to damage the screen in the process of the consequtive steps. Tiny shiny shards to vacuum.

I notice in video instructions, removal of battery and motherboard, opening pick inserted from inside out, less or no screen debris caused, but commented is, not to remove the screen unless it is already broken.

STOP. As noted above…Use the Video Method. When I was finally able to begin detaching the screen, the glass separated off, while the screen remained attached. This action sheered of the connection to a front-facing sensor which remained firmly embedded by adhesive to the front glass.

In retrospect, removing the main board, heating and using picks from the back worked with somewhat less effort and better control.

insert opening pick down ~30 degrees to go between screen and frame. Parallel to glass went between glass and screen.

Screen was adhered to underlying frame, around the battery gap. Pry into and heat that adhesive to loosen the screen there. To me, it seems hard not to damage the screen in the process. Tiny shiny shards to vacuum.

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.

Hmmm ok… this isn’t what I see. I seem to have peeled off the glass layer from the display itself. I have a silver looking display to yet remove before I see any of the frame or ribbon cable shown in the picture above. And yet there was indeed black adhesive strip that I was peeling away during this process, so I thought I was doing the right thing.

Solved it. I nearly gave up; I had heated it till the frame was almost too hot to touch, not happy with that, as components could be damaged. Also I couldn’t find anywhere to get a spuger or guitar pick into around the edge, it was all too narrow. But eventually I found I could get a guitar pick under the cables at the top of the screen and start peeling from that direction. Also the screen would crack and splinter at this point, so it was important to move slowly and keep the pick flush and not curl it up too much, to crack as little as possible. And of course, minding the part where the cable is connected on the top right. And I covered it in sticky tape because it was splintering everywhere during this process.

They’re not kidding - the screen does not survive removal during this process, so it better already be destroyed when you do. In fact I even had little pieces of “display” still stuck to the adhesive when I was done. A foldable display this ‘aint.
