Samsung Galaxy Fold Disassembly: Better Sealing Compared To The “first Generation” Screen Reinforcement

[Bestbuy618 Mobile Channel] The launch was a mixed bag, but that didn’t stop me from naming the Samsung Galaxy Fold one of the most notable smartphones of the last two years; at least in terms of innovation, the Samsung Galaxy Fold has made significant strides. Although Samsung was a little hasty in bringing it to market, which resulted in a series of problems (this time Samsung corrected its mistakes in a timely manner), today we look back and see that the Samsung Galaxy Fold still has many shining points, so that the “sunset” of the smartphone industry, a little more vitality. Now we may not be surprised by the folding screen smartphone, but last year and even at the beginning of this year, folding screen is still a “new As a result, for the Samsung Galaxy Fold to be listed, the industry both inside and outside of Samsung has high hopes.

However, as previously speculated, folding screen phones still have a slew of “hidden problems,” and Samsung was not spared. So, after the first half of the sale, and had to be adjusted, know that in September before the market again, more and more folding screen-related devices have attracted user attention, particularly the two products recently released by Microsoft – Surface Duo, Surface Neo.

The Surface Duo is still distinct from the Samsung Galaxy Fold in that it is a “dual-screen smartphone” (consisting of two 5.6-inch screens), whereas the Samsung Galaxy Fold is a smartphone with a folding screen. In contrast, I continue to believe that Samsung’s “work” is more science fiction. The unique design of the Samsung Galaxy Fold also piques our interest in the internal structure of this product; in April of this year, the well-known foreign website iFixit released a disassembly report on the Samsung Galaxy Fold, but for some reason (Samsung pressure? ), they temporarily removed the content.

However, for some reason (Samsung pressure? ), they withdrew the content temporarily. Now that the Samsung Galaxy Fold “second bullet” has arrived, iFixit stated that this disassembly of the product is the latest hardware revision of Samsung, that is, the version on sale, what are the improvements, and whether there are still flaws? Let’s look at it through another disassembly by iFixit.

In terms of cameras, the Samsung Galaxy Fold has a luxurious configuration: a 10-megapixel selfie camera on top of the outer screen, a dual camera on the inside consisting of a 10-megapixel selfie camera and an 8-megapixel bokeh camera, and a triple camera on the back of the phone consisting of a 16-megapixel super wide-angle camera, a 12-megapixel wide-angle camera, and a 12-megapixel telephoto camera, for a total of six cameras. According to iFixit, the weight of this disassembled version increased by 13g when compared to the initial version, weighing 276g. Furthermore, iFixit stated that this Samsung extra “The company also stated that the phone’s protection film should not be lifted off the phone, do not place items on the screen when folded (no one should do this, walnuts? …

In terms of appearance, the Samsung Galaxy Fold is much narrower than the Samsung Galaxy S10 after folding; the unfolded area is smaller than the iPad mini 5, but thanks to the narrow bezel design, the Samsung Galaxy Fold is close to the iPad mini 5 in terms of usable area. Furthermore, iFixit reported that Samsung made some design changes, such as adding a protective cover to the fold to prevent foreign objects from entering the interior of the body. After folding the phone, there is still a relatively visible gap at the pivot, which will not immediately cause damage to the screen, but there is still the possibility of dust entering the phone.

In this regard, iFixit that these gaps, gaps completely closed is extremely difficult, but overcoming this point in the future will obviously be very beneficial. Of course, the thickness of the phone will be more “objective” after folding, but the user can still fit into the pocket relatively easily (long and thin). After folding, the phone is not horizontal on both sides, but rather thicker on one and thinner on the other, with a small gap between the screens.

Around the screen, there is also the former raised bezel, which can play a certain role in screen protection (can also “hide” the screen above the protective film). As for the crease, or can see, this may be one of the folding screen phones at this stage difficult to solve the problem. Let us proceed to the other side.

Unlike the rear camera, the small 4.6-inch screen on the outside of the Samsung Galaxy Fold had to be removed due to the “double-sided screen.” On the other side of the reality panel you can see Samsung’s own S6SY761X touch controller. Next remove the batteries, two of them! The batteries are glued to the body (take some time)…the two batteries have a capacity of 8.22Wh and 8.65Wh, or 2135mAh and 2245mAh respectively. However, according to iFixit, the Samsung Galaxy Fold’s battery capacity is lower than that of most tablets, including the iPad mini 5 (19.32Wh).

Now, first remove the motherboard with the rear triple camera; you’ll notice a heat sink beneath the motherboard.

Separate the cameras as follows: 12MP wide-angle camera and 12MP telephoto camera in the red box; 16MP super wide-angle camera in the orange box; 10MP selfie camera and 8MP bokeh camera in the yellow box; and 10MP selfie camera in the green box.

At this point, a protective frame (held in place by an adhesive) can be removed from the outside of the screen. iFixit claims that there are improvements here compared to the “original” Samsung Galaxy Fold, where there were no other components inside the protective frame, but a T-shaped plastic frame has been added to the phone to protect the screen more effectively even if the bezel falls off. At the same time, this avoids the existence of gaps and the entry of dust, but iFIxit believes that this may require practice testing to determine whether it can truly eliminate the dust into the display.

The next separation sub-display module, the process requires great care. According to iFixit, screen replacement is difficult; however, Samsung has launched a service for this $ 149 can be replaced (only once).

However, it is still recommended to use with caution to avoid damage to the screen as much as possible. iFIxit that the use of plastic rather than glass as the OLED substrate reduces the risk of broken displays to some extent, but the screen may also be damaged for other reasons.

The connection between the display and the motherboard is made via an extra-wide cable, and as the disassembly progresses, the reinforcement measures put in place by Samsung begin to show. An additional metal layer can be seen on the inside of the screen, between the screen and the back panel, which corresponds to the phone’s folded hinge area.

The “first generation” Samsung Galaxy FoldThe “reinforced” Samsung Galaxy Fold The display module is now laid flat, with little evidence of the fold. A “premium polymer protective layer” (similar to a cell phone protective film?) sits above this screen. iFixit also stated that removing this protective layer would most likely cause damage to the display module, so Samsung’s advice was followed this time.

Back to the hinge on the body frame, iFixit claims that Samsung has added a layer of “protection” to the original exposed hinge, which can prevent some debris from the gap from entering the hinge, increasing wear and tear, or causing folding failure. However, iFixit believes that with increased use of time, there will still be debris into the hinge, but it will hardly affect the display, which also avoids the display because there are foreign objects left in the fold due to pressure reasons. The hinge has four spring clasps to provide enough damping to keep the screen stable in the open position.

The hinge, which is attached to the stopper frame’s central pivot, is designed to withstand torsional forces. The hinge in the center has gears that keep the phone’s left and right sides open, and at the pivot, you can see two lines with good extension that complete the connection between the left and right sides, and these two lines are modular in design.

Because of this hinge pivot system, Samsung claims the Galaxy Fold can be folded 200,000 times. It remains to be seen whether this figure can be achieved during actual user use.

According to iFixit, following the secondary listing, Samsung made several changes to the Galaxy Fold, including adding covers on both sides of the folding area to improve sealing; adding tape to the inside of the hinge to prevent debris entering the display from the back; and reinforcing the display panel (metal layer).

There are also some minor changes, such as an increase in the size of the protective film (film) that protects the inner flexible screen, so users will not see the edge of the protective film when they do not go to the edge of the protective frame, and so on. So the Samsung Galaxy Fold’s second disassembly is complete. Here’s a family photo.

iFixit’s repairability score for the Samsung Galaxy Fold has not changed, remaining at 2 points (out of 10, the higher the score, the easier it is to repair). Among them, the Samsung Galaxy Fold uses standard Phillips screws, many components are modular and can be replaced independently, and two designs to reduce the difficulty of disassembly.

While the folding area using mechanical components may wear out over time, resulting in the hinge and display force needing to be replaced; inside the flexible screen is still “fragile,” the user is likely to pay for its repair costs; the battery can be replaced, but the use of glue in the With more time, the folding screen phone will face more challenges in a complex environment; whether the task can be completed under long-term testing remains to be seen.
