Smartphone? Tablet? The Samsung GALAXY Note is taking the world by storm and we thought we should take one apart (to see what’s inside), so you don’t have to.



1. S Pen

What would the GALAXY Note be without the S Pen? Still a pretty awesome phone, but that’s not the point.


The S-Pen uses electromagnetic induction technology and has pressure sensitivity equal to a regular pen.  Your input on the screen varies with the amount of pressure you put, making it a seamless re-creation of writing with an actual pen.


 2. OCTA (On-Cell TSP AMOLED) 

The 5.29 HD Super-AMOLED display (1280×800) is combined with the Touchscreen panel (TSP).


3. Digitizer

The digitizer interacts with the S-Pen to sense the pen-tip’s location and the amount of pressure.  By establishing an electromagnetic field, it blocks the noise and magnetism through the shield plate.


4. Bracket

The bracket is like the Note’s backbone, holding together all the custom parts to maximize space efficiency.


5. Main PCB

With over 1000 different parts included in the mainboard, it fully utilizes Samsung’s integration technology.


5-1 (Front)

Acceleration Sensor

Detects the tilting motion of the Note, whether you’re turning it sideways for a widescreen view or turning it to play games.

Gyro Sensor

Detects the up, down and sideways motion of the phone.

Proximity Sensor 

Detects when a detectable object comes close to the phone.  Prevents unwanted input during calls or other situations.

Light Sensor

Detects the brightness, used to adjust the screen brightness accordingly.


With BT 3.0 + HS support, allows for fast transmission between mobile devices.


Can used for close-distance communication, allowing users to use the phone like a credit card or transportation card.


Used to actualize the S Pen’s movement and use.


Front Facing Camera, DMB, GPS


5-2 (Back)

Internal Memory

16/32GB of memory for storing lots of data including videos, music, etc.

LTE Modem Chip

The latest in communication technology, widely known as 4G.

1.5GHz Dual Core AP Chip

Twice the processing power with a dual core chip.


Back facing camera (with flash).


6. Rear case

The area that stores a variety of antennae and wires.


7. Battery Cover

The battery cover also stores the NFC antenna.


So that’s it. Hope you’ve enjoyed it. If you want to see what’s inside a Samsung Smart TV or the Galaxy S II, check out the links below:
