视频概述

-
这两款手机都有多个正在流通的版本——我们选择了支持 5G 毫米波技术的美国版本,以便为你带来最完整的拆解。以下是我们这部手机的参数:
-
骁龙 865+ 处理器外加 8GB (Note 20) 或 12GB (Ultra 版本) 的 LPDDR5 运行内存
-
在 Note 20 上的6.7" (2400 x 1080) 以及在 Ultra 版本上的6.9" (3088 x 1440) Infinity-O AMOLED 显示屏,Ultra 版本支持 120Hz 的刷新率
-
128GB 的储存空间,Ultra 版本可通过micro SD卡扩展至最多 1TB 的附加储存空间
-
每部手机都有四个摄像头,其中都包含了一个 10 MP 的前置摄像头以及 12MP 的超广角摄像头。Note 20 具有一个 12 MP 的广角摄像头以及一个 64 MP 的长焦镜头,Ultra 版本则具有一个 108 MP 的广角镜头以及一个 12 MP,支持5倍光学变焦的潜望式长焦镜头。
-
电池:Note 20 为 4300 毫安时,而 Ultra 版本则为 4500 毫安时
-
5G 及 超宽带连接技术,外加 4x4 MIMO LTE,802.11ax Wi-Fi,以及蓝牙 5.0
-
-
-
首先,让我们用 S-Pen 来记录一下有关摄像头凸起的笔记。如果你想让摄像头的玻璃远高于后盖,那么 Note 20 Ultra 将会是你最佳的选择。
-
iPhone 11 Pro Max 凸起的三镜头现在看来是一个很克制的高度。对于各类抱怨,我们深表歉意。
-
谷歌可能是最有说服力逆转这一情况的智能手机制造商,通过更低成本的尖端软件来代替物理硬件。三星的做法很酷,不过我们的(窥视)摄像头仍然对 Pixel 5 开放。
can you tell me how much does the camera module protude?
good evening I have a note 20 ultra 5g and following a fall of not even 50 centimeters the screen is cracked knowing that I buy it in its sealed box
-
-
在这个步骤中使用的工具:Essential Electronics Toolkit$29.95
-
与大多数手机一样,进入内部后的第一件事就是拧螺丝。而我们的 Essential Electronics Toolkit 就在这里,准备并等待着去把它们拆开。
-
在拧了一些非常紧的中框螺丝后,这是我们第一个漂亮的内部结构图(在可见范围内,管他呢)
-
每部手机的听筒都装在了天线组件的上面,包含了专用的外罩——这是第一次!听筒组件是矩形的,被一个红色的垫圈所包裹。它仍然会像 Note 10 以及 S20 的听筒那样,通过中框内的通道传递声音,但是新的、更大的外壳应该会提升音频的质量。
-
这两部手机还带有一个后置麦克风,直接放在后盖上。值得庆幸的是,它们通过了一个友好的、易于维修的弹簧触点进行连接,这就是为什么在我们打开后壳时没有把这些东西弄断。
-
-
-
-
接下来是:摄像头。必须先把两块主板拆出来。
-
Note 20 Ultra 继承了 S20 Ultra 的区域变焦模块,但采用了一个更小的 12 MP 传感器(点击该链接以详细了解潜望式镜头的原理)。而一般的 Note 20 则没有“区域变焦”,而是依靠了一个像素更加密集的 64 MP 传感器和一些裁剪的魔术来实现的。
-
广角镜头模块则相反,Note 20 Ultra 采用了一个巨大的 108 MP 传感器——就像 S20 Ultra,默认模式采用了 12 MP 像素。同时,Note 20 则配备了一个适中的 12 MP 传感器。
-
这两款 Note 都没有搭载 S20 Ultra 上的 40 MP 前置摄像头——而是都装有了 10 MP 的前置摄像头传感器,同时自带了一些不幸的平滑效果。
-

-
感谢三星,让这些主板看起来就像 AT-ATs。我们希望现在随时能在 Hoth 开启一场战争!以下是一些配置:
-
骁龙 865+ 处理器,分层放置在三星 LPDDR5 运行内存下
-
三星 KLUDG4UHDB 128 GB 通用闪存
-
高通 SDX55M 5G RF 调制解调器以及 SMR526 中频 IC
-
高通 QDM4820, QDM5872, 以及 QDM4870 前端模组
-
恩智浦 11OUV2H 和 9468B3,可能是恩智浦 "行业中首次结合超宽带测距, NFC, Secure Element, 和嵌入式 SIM" 方案中的一部分
-
美信 MAX77705C 电源管理芯片

有什么比拆下 Note 20 电池更糟糕的事情?要同时拆下两个...
-
幸运的是,我们有方便的解胶剂。倒一点进去,然后用一对吸盘、一些耐心和一点点说服力就可以帮助我们安全地拆下两块电池,而不费吹灰之力。
-
直到现在,三星的电池还是粘在一起的,但我们还没有放弃希望。三星,如果你在看的话,这是一种更好的方式(而在此之前,有一种更更好的方式)。
-
这些 Note 20 以及 Note 20 Ultra 电池的容量分别为 16.69 和 17.36 瓦时。
-
两者均击败了 iPhone 11 Pro Max 中的 15.04 瓦时电池,但是要落后于 S20 Ultra 中 19.30 瓦时的怪物——不必为手写笔腾出空间,因此无需压缩电池所使用的空间。
-
-
-
这些手机最奇怪的是,到目前为止,所有东西都位于主板的下面。
-
还是很奇怪,看样子有些其他的 Note 20 手机们配备了铜热管——但不包括我们的美国版本型号。难道是国际版的猎户座(Exynos) SoC 需要和我们的骁龙处理器不同的散热硬件?
-
我们来自 JerryRigEverything 的朋友扎克(Zack)告诉我们,他的韩国版本型号也有一样的石墨导热片。请继续关注详情。
-
我们的另一个想法是,也许这归结于发热量巨大的 5G 毫米波硬件,但不是所有 Note 手机都具备——但是那也说不通。是不是在新的冷却硬件上进行了某种A / B测试?这里需要一些逻辑,但我们无法将其寻找出来。请让我们了解你的想法。
-
说到毫米波模块——我们的手机都拥有它们,但每部手机只有两个。相比之下,Note10 + 5G 和 S20 Ultra 则有3个。硬件是否进行了改进,而改进后只需要两个?或者还有其他的原因?
-
-
-
最后离开他们由金属制成的家的是两块 AMOLED 显示屏。在它们的后面,是我们一直在寻找的一些铜!
-
三星一直在其显示器上衬以铜以辅助散热——尽管在主板下方的散热介质换成了石墨,但情况仍然如此。
-
在每块屏幕的背面都装有一个超声波指纹传感器——同时,康宁的新型大猩猩玻璃 Victus 保护了前面板——“有望显着改善耐跌落和划伤性能,这在大猩猩玻璃家族中尚属首次。”
-
-
-
我们差不多就要结束了,但是,如果你需要看最后一眼,这里是 Note 20 Ultra 各个角度的X光片。
-
我们在拆解中找不到的一件东西是:超宽带天线,就像我们在 iPhone 11 系列中发现的那样。 我们是否以某种方式错过了它,还是三星的实现方式完全不同?
I’m upgrading from a Note 8 to the Note 20 Ultra, black. Upgrading because my Note 8 caught a little sun and the battery swelled, but the phone still worked perfectly, even during charging. Love this phone and think it’s well worth the price since I’m a bit of a tech head and love all the stuff the phone comes with. You guys take care.
-
-
-
这就是关于 Note 手机的拆解!
-
用户 Space Saga 发表了我们最爱的回答:三星并没有故意将数字 20 添加到今年的 Note 系列中——这只是一个错别字,但在任何人注意到之前,泄密已经开始。
-
恭喜!您赢得了一对超级好维修的盖乐世蚕豆。(为什么不用这个名字?)
-
与往常一样,我们将会进行可维修性评分——非常适当的结尾,您觉得呢?

yet this guy tears it down quickly and has little trouble with the adhesive using the proper solvent :)
It’s just isopropyl alcohol, and unfortunately it doesn’t help all that much. You can see from the video how tedious it is. Now try doing that after a year, when the adhesive has hardened, and the back glass is shattered. And then try putting it back together with fresh adhesive afterward. Nobody is saying it’s impossible, but this phone’s 3/10 repairability score is well earned.
Anyone know what kind of adhesive is used?
I would expecting to see that the instructor would ware ESD strap , remove the Sim tray before losing any screws and then to cover the cameras with tape protector and keep away from finger prints.
Good luck
How is the camera bump sealed to the rear glass?

What sd card does this support LOL. Does it have the second row of pins for UHS-2?
No, I don’t think the the SD card slot has the second row of pins for UHS-II. UHS-II card is usable but runs at UHS-II speed.
Don't see any mention of the haptic motors, and whether Samsung has gimped the regular Note 20 as well?
Buds Contest:
Well, There was a Note 10+, quickly followed by the “Note 10+ Max” , which tended to blow up whenever you accessed Google! . I believe there also was a “10+ Max Ultra”(Which was huge!) prototype. but the original designs were destroyed in an arson event allegedly, attributed to an industrial espionage incident, again allegedly, attributed to having been caused by ex Apple employees. By the time all of these variants were sorted out , it was already the beginning of 2018! A guy in marketing came up with “S19/Note19” but, it was nixed! 2020 has some significance in the Chinese calendar (I know, Korea?!?) and it was just around the corner so, …. Taa Daa!!
everyone knows the REAL reason for the samsung note going from 10 to 20 is simply because apple patented the numbers 11-19 in order to thwart samsung’s progress of the note series! :)
Is the Note 20 5G version screen the same as the regular version?
Hi, I don't know if you read this. I have Exynos Note 20 Ultra, by mistake I poked the upper microphone hole adjacent to the SIM hole when I was trying to eject my SIM cards. Now, I'm worried about the phone’s IP rating. Is it compromised? I don't know if I poked too hard. I did the *#0283# microphone test and it came good. All three mics gave feedbacks.
everything is ok, this should not be a problem (hole has 90 deg turn so you cannot damage the membrane)

i just finished replacing the LCD screen for my note 20 ultra (it cracked from the top of the up volume key to the hole on the top frame almost precisely from a very minor drop only 3 weeks into owning it) and i cant help but feel that this was one of the easiest screen replacements i’ve ever had to to do. ok, the rear glass is a pain to remove and you need to exercise patience however, once inside after removing a bunch of screws that, beside three near the charging port are identical, every phone component inside popped out beautifully and they were substantial in nature making it easy to remember where they came from, what order they came out in and pretty hard to misplace / lose. for the battery i just laid the phone, broken screen down on at 90 deg C heat mat for a couple of mins and the battery came off with relative ease. yeah, one of the easiest almost foolproof screen replacements i’ve ever done. i have to add that a heat pad made a big difference in controlling how much heat was applied.
hello Paul M - would you be able to make a guide for this? so just to change the glass (right? not the oled itself) you had to burrow from the back all the way to the screen? I have a note 20 ultra with less then an inch long microcracks at the right edge (from bottom edge of power button to the top edge of the top volume button) Touch etc all fine no issues with the display Thanks

Buenas tardes, Un Note 20 ltra, despues de cambiar la logica, sigue conservando la IP68?
hi i would like to know how the mic holes get the water proofing seals? ive read the other comments about poking the upper mic by mistake. i also did it. ive seen live tear down and i was looking for a hole on the top mic from the inside of the phone on your video. im just curious where did they put the seal to water proof it? i did poke the top mic by mistake but i went in REALLY hard. i have been searching around the internet bout the water proofing seals and where did they placed it. is it on top of the 90 degree curve? or the bottom?
what is circled in the image I've linked to?
I went to a water park and the phone was soaked in water. I left it in the rice container for 3 days out in the sun and it finally booted up. The phone was in airplane mode, no wifi, no network. I did a reboot and still nothing. When i ejected SIM tray it said no SIM found but when i put it back in, no network or wifi. I tried to reset wifi and network several times but didn't help. I cannot do a factory reset because it says i needed wifi. At this point im guessing these 2 features are on 1 component and it got damaged somehow. What part do i order so i can swap out and bring my phone back to life? Thank you
Hi ifixit, My phone Samsung Galaxy Note 20 Ultra 5G and a charging port failure after replacing it still won't take charge in (Wireless charger works). Is it because of the failure in bottom board that control mic and bottom speaker. I need help regarding the failure in the cable charging system. The power supply work perfectly fine no issue with it.
¿Cuando sacas la tapa trasera, que es el la pieza que va pegada a la parte del cristal de la cámara que además conecta en la parte delantera del móvil?
