Samsung Folding Screen Phone Galaxy Z Flip Disassembled: Ultra-thin Glass Turns Out To Be This


[Bestbuy618 cell phone channel]Due to the epidemic, the “first round of 2020 cell phone war,” which was supposed to begin in February, has been postponed, but the excitement has not subsided. After a full year of efforts in 2019, consumers have a more comprehensive understanding of 5G, 5G phone prices are also close to 4G phones, so in 2020, 5G is no longer a strong contender for the headlines, “folding screen” to see the opportunity to succeed at the top! Samsung released a new generation of folding screen phones Galaxy Z Flip after the success of widespread attention, its thunder appears to have overshadowed the Galaxy S20 series unveiled together. I believe the Galaxy Z Flip’s success is due to two factors: the new design and the “value” price.

Unlike Samsung’s Galaxy Fold and W20 5G folding phones released last year, the Galaxy Z Flip has a top and bottom folding design, similar to the Motorola RAZR, which is similar to a flip phone. So the Galaxy Z Flip is even smaller when folded, and with Samsung’s exterior sculpting, it’s the most stylish folding screen phone available.

In addition to the unique design of 2019 folding screen phones, there is a point to consumers left “engraved” memory – the price. Despite Apple’s efforts, four digits are no longer the top price for a flagship phone, but folding screen phones are also several thousand dollars more expensive, such as the Samsung Galaxy Fold China for 15,999 yuan, Huawei Mate X for 16,999 yuan, and W20 5G for 19,999 yuan. In comparison, the Galaxy Z Flip’s $1,380 price tag is quite reasonable (Samsung will hold an online launch event in China on February 27, and the country’s price may be revealed).

With a more mature design, a more affordable price, and a more powerful configuration than the RAZR, has the Galaxy Z Flip become a more perfect folding screen phone? A few days ago, the well-known foreign website iFixit released a comprehensive disassembly of the Galaxy Z Flip, which is equipped with Qualcomm Snapdragon 855 mobile platform, 8GB of RAM, 256GB of storage, 12MP main camera, 12MP ultra-wide angle external camera, and 10MP front selfie camera.

The Galaxy Z Flip is made of glass on both sides, with a texture similar to current flagship phones, which means the phone is prone to shell shattering if dropped (glass panels have already broken in foreign Dada tests). By x-raying the phone, you can see that the Galaxy Z Flip has a small stacked motherboard with a more complex and sturdy spring hinge, and the corners of the body are equipped with magnets inside to ensure stability when folded. When comparing the Galaxy Z Flip to the Galaxy Fold, there are few similarities in terms of appearance between the two, except for the folds, which can be said to be the two current design ideas for folding screen phones, according to iFixit.

Except for the creases, the unfolded Galaxy Z Flip is very similar to our familiar straight smartphone, and thanks to the perforated screen design at the top of the screen, it doesn’t leave a conspicuous bangs like the Galaxy Fold. Before the official teardown, iFixit conducted a very “interesting” but disastrous experiment with the folding screen phone. During the press conference, Samsung mentioned that the new pivot design of the Galaxy Z Flip includes extremely fine fibers inside to prevent dust entry and protect the delicate mechanics inside.

So iFixit placed the Galaxy Z Flip in a sealed bag and added a large amount of purple powder (to simulate dust), then removed the phone after “mixing it well” to test it. Not surprisingly, when unfolding the phone, it was clear that there was something foreign inside the spindle; the next step was to begin disassembly, first by heating the glass panel on the back of the phone to soften it and then removing it with suction cups.

In other words, if the phone’s glass shell is broken, replacing it is actually easier.

Then, on the side of the phone, remove the wireless charging coil; at this point, you can see that there has been an invasion of pink particles. Unlike the Samsung Galaxy S and Note series, folding screen phones like the Galaxy Z Flip have difficulty supporting high levels of dust and water resistance, so users must still be concerned about spills and other issues during daily use. However, iFixit also stated that Samsung for Galaxy Z Flip’s motherboard and other internal components or a certain amount of protection. Now take out the motherboard, which also has residual pink particles.

Galaxy Z Flip uses a double stacked motherboard, which can significantly save space inside the body (of course, heat dissipation also faces challenges), Samsung Galaxy Note 10 series also uses such a design. The following components are found on one side of the two motherboards: red box for the Samsung 925 K3UH7H7 (presumably the Snapdragon 855 layered with 8GB of memory); orange box for the Samsung 949 KLUEG8UHDB (possibly 256GB of flash memory); yellow box for the Broadcom AFEM-9106 front-end module; green box for Skyworks 78160-51 low-noise amplifier; cyan box for Qualcomm SDR8150 RF transce

The following components are located on the other side of the two motherboards: Qualcomm PM8150 power management IC in the red box; Qualcomm WCD9341 audio codec IC in the orange box; 2MIWO4 in the yellow box; DOS04 09Y44E W1948 (probably the backlight IC) in the green box; and Qualcomm QDM3870 RF front-end module in the cyan box. In comparison, the Galaxy S10 battery has a capacity of 13.09 Wh, while the iPhone 11 has a capacity of 11.91 Wh. The battery of the Galaxy Z Flip is difficult to disassemble and requires patience to handle the glue.

Finally, there is the screen of the Galaxy Z Flip, and the ultra-thin glass used for the first time in a folding screen phone. Individually removing the screen module requires first removing the protective bezel on the outside of the screen, heating it to soften it, and prying it open.

According to iFixit, a metal support plate was added to protect the screen’s inner pivot area.

Now is the time to reveal the true nature of the Galaxy Z Flip’s “ultra-thin glass.” The top layer of the Galaxy Z Flip screen is plastic, according to iFixit’s teardown, and Samsung also stated in a response to foreign media that the Galaxy Z Flip screen has the same layer of protective film on the surface as the Galaxy Fold. In a response to foreign media, Samsung also stated that the surface of the Galaxy Z Flip screen, like the Galaxy Fold, has a protective film. According to iFixit, this kind of defeats the purpose of the “ultra-thin glass,” and with the plastic layer, the scratch-resistant advantages of glass cannot be shown; however, when iFixit tried to separate this layer of plastic protective mold, it discovered that the middle of the ultra-thin glass is very fragile, and any attempt to tear the protective film will shatter.

The protective film not only protects the screen, but also “protects” the glass. With the screen removed, the Galaxy Z Flip’s hinge was disassembled. iFixit began by removing the tape that protects the hinge inside the body, and then we noticed a lot of purple powder.

However, iFixit pointed out that the tape did not block the powder, but that in order to prevent further powder invasion to the side of the screen, almost all residue in the hinge was removed. Furthermore, there are some flexible cables connecting the two parts of the phone in the middle pivot area, and just as Samsung mentioned the fiber fine brush, iFixit expressed some embarrassment, you can clearly see the purple powder attached to it. Although it can play a certain protective role, in the actual use of the process, if more and more dust accumulates over time, its protective effect will be extremely limited.

After removing the hinge module, it is not difficult to find a large amount of purple dust attached to it, but iFixit also stated that this mechanical structure is very strong, as to how to avoid the accumulation of dust for a long time. Perhaps it is only left to Samsung to solve the problem; after all, 200,000 folds means that users can use it continuously for 4-5 years.

Here’s a family photo of the disassembled Galaxy Z Flip, which iFixit considers more of a “novelty luxury.” In the end, iFixit gave the Galaxy Z Flip a fixability score of 2 out of 10. iFixit believes the Galaxy Z Flip’s use of universal screws and partially modular, interchangeable design reduces the difficulty of repair. Otherwise, the phone’s glass panel on the outside complicates disassembly, and the phone’s battery, while replaceable, necessitates proper disposal of poorly routed cables and adhesives during disassembly.

Furthermore, the folding components of the Galaxy Z Flip may wear out over time and may need to be replaced.
