After Anandtech disassembled the Nexus 4, Google's "fourth son", iFixit, another website specializing in disassembly, also disassembled it. Let's take a look at the disassembly process of iFixit (click the picture to open the large picture in a new window):
1. Nexus 4 main parameters:
- 4.7 inch 1280 x 768 IPS LCD screen;
- Qualcomm Snapdragon S4 Pro SoC, 1.5 GHz CPU;
- 2 GB RAM；
- 8 megapixel rear camera, 1.3 megapixel front camera;
- NFC support
- Android 4.2 (Jelly Bean)
Front, back and details before disassembly:
2. iPhone 4S, iPhone 5, Samsung Galaxy Nexus Galaxy S III、LG Nexus 4、Galaxy Note II， And Nexus 4, 7 and 10 family photos
3. Compare with iPhone 5 side by side and take the card needle.
4. Start with Cato.
5. Unscrew two T5 Torx screws fixing the rear cover, and carefully open the rear cover with a plastic shell opening tool:
6. Rear cover and Coil and circuit board.
7. There are two screws above the battery to fix the power line. The battery of the Nexus 4 is firmly standing on the chassis, which requires a lot of effort.
8. Battery parameters: 3.8V, 2100mAh. The battery is produced by LG itself.
9. Disassemble loudspeaker. We noticed that speaker is fixed by two screws, and there is no extra cable connection. This also reduces the failure rate.
10. The next step is to remove the plastic shell on the main circuit board. After removing the shell, the entire Nexus 4 will no longer have screws.
A total of 15 screws of 4 models are used on the.
11. The plastic shell also contains a vibrator. Please refer to another article about the vibrator《 How is mobile phone vibration realized? 》
As for the problem mentioned above by Youdiaosi that "mobile phones can intelligently recognize the vibration status and reduce the noise caused by strong vibration" may lead to the elimination of some peripherals of silicone female mobile phones, Nexus 4 said that there is no pressure.
12. Carefully remove the connection with other positions to remove the mainboard.
13. The 8 megapixel camera kit on the motherboard. It is marked "AC2AD D4A261".
14. Of course, there is a 1.3 megapixel front camera. Marked "Y411A".
15. Play: The main circuit board and components are international brands.
