    Hello. I would like to ask if I bought the screen together with double-sided tape, do I have to give this adhesive?

    Hello. Either the glue or the tape depends what phone it is and what you stick with?

    I mean, you stick the display together with the glass, right? This is how the original tape is not needed, I will let you load the glue because you will not come off with the housing.

    As it was factory, you can let it stick to it.

    As for the original Samsung panel, it has already applied adhesive tape, which in most cases is enough, but I personally carry the adhesive, because I have encountered cases that the tape was letting go. If the sellers gave the tape separately, I would not advise using it, then pour the B7000 glue alone. Do not give double-sided tape under LCD, it hinders work in many cases.

    This and I will be a little hooked on the subject. I need to paste the display to S7 and such a question how to spread the glue? Applies to glue B7000
    I think about the place where the buttons are most. Do I give it all or just about? Top and edges are known not to cover the camera and sensors, but as with the bottom. Is it better to buy a sticker?

    In places such as buttons / sensors, I try to distribute the adhesive in the least amount possible, so that it does not get to places not intended for this

    In this case (and other models with thin OLEDs) nowhere. I would definitely recommend buying the original, cut double-sided tape that will have the correct thickness. You can then optionally add gently T7000 on the top and bottom edges, but if the frame is fine, there is no curve etc., then you should not need it.

    In turn, I would not recommend gluing this type of display (only) on liquid adhesive for safety reasons. They are delicate and can damage them if they are stressed. I would not advise giving extra double-sided tape or b7000 under the display.

    In my experience, gluing B7000 without original Samsung tapes is very good. At the moment when the panel has the original Samsung tapes and is ordered from the manufacturer, it adds glue for sure and it does not bother, and greatly improves gluing. Even on other models, the adhesives on the B7000 and I have not encountered problems.

    Everyone has their own experience and learns best on their own mistakes. I have already seen S6 or S7 pasted on some normal two-sided and also worked, but I also saw such where after a week or two suddenly the display was stained with stress or cracks somewhere underneath which could have been made or badly cleaned frame, or also with glue which he could get somewhere underneath.

    The original S7 kit comes without glue at the factory - it's not the only one, but it's already inconsistent with Samsung. Personally, I put only cut org in this model and give a little B7000 on the edges (top and bottom, I do not move the sides at all) and I have no problems. Expensive, when it comes to this model, they are not honest, there is not even anything to think about. In other models - at least the J5 or J7 2017 series similarly (there the double-sided org top and bottom is very thick), where it also adds b7000 also to the display itself, where the glue org was.

    As he wrote blahfff the original is without glue. I ordered the sticker and gave it gently B7000 on the edges and gently on the edge and is great.

Topic summary

✨ The discussion revolves around the use of B7000 glue versus double-sided tape for screen replacement, specifically for the Samsung Galaxy A500 and other models like the S7. Users debate whether the adhesive tape provided with the screen is sufficient or if additional glue is necessary. It is noted that original Samsung panels often come with pre-applied adhesive tape, which is generally adequate, but some users prefer to apply B7000 glue for added security against potential detachment. Caution is advised against using double-sided tape under the LCD, as it may hinder functionality. Recommendations include using original cut double-sided tape along with minimal B7000 application on the edges for optimal results.

FAQ

TL;DR: "Personally, I put only cut org in this model and give a little B7000 on the edges." Poor prep or liquid‑only glue caused failures in 1–2 weeks on S7‑class OLEDs. Use die‑cut tape first, then minimal edge glue if needed. [Elektroda, blahfff, post #17551231]

Why it matters: For DIYers and repair techs choosing between B7000 and OEM tape, this clarifies when, where, and how to bond screens securely without stressing OLEDs.

Quick Facts

Should I use B7000 glue or double‑sided tape for a phone screen?

On thin OLED modules like the Galaxy S7, install original die‑cut tape. Optionally add a small bead of T7000 on the top and bottom edges. Avoid liquid‑only gluing to reduce stress damage risk. Do not add any adhesive under the display. [Elektroda, blahfff, post #17551162]

Is the factory adhesive on Samsung screens enough, or should I add glue?

Factory‑applied tape on original Samsung panels is usually sufficient. Some techs still add B7000, because generic tape sometimes lets go. If your seller included separate tape, skip it and use B7000 instead. [Elektroda, seba1601, post #17550774]

Can I put thin tape in the middle under the display for support?

No. Do not place tape under the LCD. It hinders work and can obstruct correct seating. This often makes future service harder. [Elektroda, seba1601, post #17550774]

Where should I apply B7000 on a Galaxy S7 or similar OLED?

Apply a little B7000 only on the top and bottom edges. Leave the sides untouched. Use original die‑cut tape for the main bond. [Elektroda, blahfff, post #17551231]

How much glue near the home button, sensors, and cameras?

Use the least possible adhesive in those areas. Keep glue out of unintended zones. Thin, controlled lines reduce seepage and sensor issues. [Elektroda, seba1601, post #17551098]

How long does B7000 take to set and fully cure?

B7000 skins over in about 3–6 minutes. It typically reaches full cure in 24–48 hours. Avoid load or flex before full cure. [Zhanlida B-7000 Adhesive TDS]

Is it safe to glue thin OLEDs using only liquid adhesive?

No. Use the original, cut double‑sided tape instead. Optionally add a small T7000 bead on the top and bottom edges. “They are delicate and can damage them if they are stressed.” [Elektroda, blahfff, post #17551162]

My replacement came with separate double‑sided tape. Should I use it?

Avoid loose aftermarket tape included by sellers. Use B7000 alone instead if no factory tape is present. Prefer factory‑applied adhesive when available. [Elektroda, seba1601, post #17550774]

Should I stack extra tape layers to increase thickness?

No. Use the original, correctly‑thick die‑cut tape for your model. Do not add extra tape or glue under the display. [Elektroda, blahfff, post #17551162]

What if the frame is warped or I didn’t clean it well?

Poor prep or a warped frame can create stress points and later damage. Some screens failed after one to two weeks. Correct frame issues before bonding. [Elektroda, blahfff, post #17551231]

For Galaxy A5 (A500), is glue or tape better?

If you’re bonding the display assembly to the housing, you can skip the original tape. Apply glue so it holds firmly to the frame. [Elektroda, Pedros050, post #17550655]

Can I combine factory tape and B7000 for extra hold?

Yes. When a Samsung panel ships with factory tape, a thin bead of B7000 can improve adhesion. Apply carefully to avoid squeeze‑out. [Elektroda, seba1601, post #17551210]

Quick how‑to: reattach a Galaxy S7 display without stressing it

  1. Fit the original die‑cut adhesive kit to the frame.
  2. Seat the display and apply a little B7000 on the top and bottom edges.
  3. Leave the sides alone; hold light pressure until the initial set. [Elektroda, blahfff, post #17551231]
