Let's take a look at the parameters of our Galaxy Note 7
5.7 inch Super AMOLED curved screen, 2560 x 1440 resolution, the fifth generation gorilla glass
Qualcomm Snapdragon 820 processor, 4GB memory, Adreno 530 GPU
12 megapixel, f/1.7 aperture, 5 megapixel front camera
64GB storage space, up to 256GB microSD card expansion
Iris scanner, fingerprint recognition
S Pen stylus, USB Type-C interface, headphone interface
IP68 waterproof and dustproof
Let's look at the bottom of the fuselage. From left to right, there are headphone connectors, USB-C connectors, microphones, speaker openings, and the S Pen. Samsung has corrected the defect in Note 5 this time, and the S Pen will never get stuck when inserted reversely.
Personally, I think this S Pen is more comfortable to use than Microsoft's Surface Pen and Apple's Pencil. Its scanning rate and pressure sense are 360Hz and 4096 respectively, which is much higher than the Surface Pen (scanning rate 240Hz, pressure sense 1024). In addition, the S Pen comes with two pen heads, one is slightly soft for writing directly on the screen, and the other is hard, It is convenient for you to use after applying the film.
By the way, if disassembling mobile phones is an Olympic sport, we can definitely win gold medals every time. First, we heat the glass on the back to soften its glue, and then use suction cups and paddles to separate the glass from the back shell.

Now we can see that there are some screws on the back panel, which are used to fix the wireless charging ring of Note 7. We guess NFC is also integrated into it.

(Radio coil)
After removing the radio ring, you can see the battery of Note 7. Insert the paddle into the bottom of the battery, and then use a crowbar to remove it from the motherboard, but this is a bit laborious. We can also see a single speaker with a built-in antenna. There is a layer of gasket and mesh lining around the speaker, which should be designed to be waterproof. The battery capacity is 3500 mAh.

Dismantle the mainboard, and you can see that there are three cameras in total. In addition to the front and rear cameras, there is also an iris scanner. The iris scanner works together with the infrared ray. When you use the iris to unlock, an infrared ray that cannot be seen by the naked eye illuminates your eyes, and then the iris scanner will capture the photos of your eyes to unlock.
This is the iris scanner (right) and front camera (left)
We used pliers to take down the main camera. It was a familiar feeling again. It was the same Sony IMX260 sensor on S7 and S7 Edge.
(Main camera)
Red: Huabang Q32FWXGIG serial flash memory
Orange: optical anti shake gyroscope, which should be the same as the semantic semiconductor K2G2IS gyroscope on S7 Edge
Now let's take a look at the chip on the motherboard.
Red: Samsung K3RG2G20CMMGCJ 4GB LPDDR4 SDRAM memory, covered with Qualcomm Snapdragon 820 processor below.
Orange: Samsung KLUCG4J1CB-B0B1 64GB UFS2.0 flash memory chip
Yellow: Anhuagao AFEM-9040 multi frequency and multi-mode RF chip
Green: NXP 67T08 NFC controller
Light blue: Qorvo QM78064, TQF6260 front-end module and QM63001A diversity receiving module
Dark blue: Qualcomm WCD9335 audio decoder
Purple: Japan Murata FAJ15 front-end module
Turn over and look at the chip on the back of the motherboard.
Red: Samsung 3420S7 G707A3 WiFi module (should include a Broadcom WiFi SoC)
Orange: Wacom W9018 touch chip
Yellow: ZF10 110630 0625
Green: Qualcomm PM8996 and PM8004 power management integrated circuit
Light blue: Qualcomm QFE3100 ET
Dark blue: Qualcomm WTR4905 and WTR3925 RF transceivers
Purple: IDT P9221S wireless power receiver, MPB02 603PD9 1625ELn, MAX77830 power chip
Next, continue to remove the headphone interface module. In order to prevent water, this interface also uses a sealing washer.
The USB Type-C interface is installed on the Note series products for the first time, but because the transition from microUSB to Type-C will experience a painful period, Samsung conscientiously gives you a adapter.
Now let's take a look at the sub board. Unlike the Galaxy S7, the sub board of Note 7 uses a very hard PCB connector, which makes its cables less weak and easy to break.
The heat pipe on Note 7 is very thin. Next to the heat sink tube is the socket tube of S Pen, which is fixed by various adhesives. At the bottom of the socket tube is a gray rubber block, which is used to protect the tip of the S Pen pen.

The volume key part looks very complicated, but it's not difficult for us.
First remove the switch with a small pliers.
Then there is a reinforced key bracket, which also uses a sealing washer.
However, the volume button is embedded in the shell and cannot be removed.
Next, let's look at the display sensor.
Red: LED message notification light
Orange: infrared transmitter
*We have seen what the iris scanner looks like before. Now this infrared transmitter will illuminate your eyeball so that the iris scanner can capture the image of your eyeball.
Yellow: distance sensor
summary
The easy repair score of Samsung Galaxy Note 7 is: four Points, the full score is ten The higher the score, the easier it is to repair.
Many parts in the fuselage are modular and can be disassembled and replaced separately
Improved cable routing, which means that the charging interface board can be removed without separating the screen
It is not necessary to separate the motherboard before removing the battery, but a lot of adhesives are used, making it difficult to repair
Due to the curved screen, it is impossible to remove the front panel glass without damaging the screen
