On the subboard at the bottom of the phone. In the dismantling analysis of the ewistech engineer, there is a trial microphone on the sub-board and a BME280 joint environment sensor corresponding to the bottom of the frame corresponding to the bottom of the frame.
Open all connectors on the front of the motherboard Remove the SIM card slot cable, fixed the metal tables of the display interface, the top of the motherboard, and the middle frame.
Platinum supports dual card dual standby, using a Micro SIM card slot, two card slots, and dual LED fill beam layers on separate soft modules, using motherboard shields as reinforcement installed on the motherboard.

Back surface of the module
After the product information stickers, you can see two wide soft rows in the box. The left side is driven for the display screen. The right side is the secondary board to connect the motherboard, the top is the touch cable, and the platinum is used. SYNAPTICS's S3202B touch chip. The entire middle frame is made of aluminum-titanium alloy, using hot forging without stress nano injection molding technology, the whole box is very strong, effectively guarantees the firmness of the phone, and there is 5 hot nuts in the box, the side of the middle frame The mirror polished metal, whether it is a sense of view or touch, is very good. The volume button is placed on the left side of the fuselage, and the mute key is the mute key and the power / lock key.

The front chip includes Haili 3GB LPDDR3 system memory + high-pass MSM897AC quad-core processor stacking chip, Qualcomm PM8941 + PM8841 dual power management chip, Qualcomm WCD9320 audio decoder chip, Qualcomm WTR1625L baseband chip, Audience ES704 voice processing chip NXP TFA9890 audio amplifier, SkyWorks SKY77629-21, SKY77753-51 and SKY77765-1 three multimode power amplifiers.
The back of the motherboard includes Qualcomm WTR2605 RF transceiver, WCN3680 WiFi, Bluetooth 4.0, FM and GPS integrated chip, BCM20793 NFC near field communication chip, InvenSensse's MPU-6500 six-axis gyroscope and accelerometer Atmel ATSAMG51G18 ultra low work Mild processor and Hissant's 32GB flash chip.
The old rule is a family.
