Last year, Xiao E once predicts the Samsung Galaxy Tab S4 and Apple iPad Pro, also has sent a box evaluation. Do you have long been a long time for the dismantling of these two devices? Small e will bring the dismantling of Galaxy Tab S4 today.
Configuration List: First review, Galaxy Tab S4 configuration.
SOC: Qualcomm Snapdragon 835 processor, 10nm process
Screen: 10.3-inch Super AMOLED full screen 丨 resolution 2560x1600 丨 Screen accounts for 80.6%
Store: 4GB RAM + 64GB ROM, support memory card extension
Front: Front 8 million pixel camera
Back: Rear 13 megapixel camera, support 2x optical zoom

After reading the parameters, what is the internal structure of TAB 4?
Since Tab 4 supports Micro SD card expansion, the side is with Taro. The first step is to remove the Catto, Tago as the PC material, and support the 400GB extended memory. The rear cover is fixed by a glue. Use the hot air gun to heat the back cover and medium frame voids, slowly open the rear cover can be found that the rear cover corresponds to the main board position and is used for heat dissipation.
The battery is designed with a dual-core, and the battery is wrapped in a circle of plastic frames, which is supported by screws, facilitates replacement.
The box is fixed by the screw and the inner support, and the box is equipped with antenna soft plate.
Remove the main panel and antenna soft plate, integrated with an iris scanning LED lamp and ambient optical sensor with a heat dissipation copper foil to fix and heat dissipation.
The card slot is designed to be separately supported, and the four-angle speaker module and the soft plate with iris scanning LED lamp & ambient light sensor.
The screen is fixed by the black gum, and the screen is separated by heating the temperature of about 80 ° C using a heating station. The screen PCB board is connected to the motherboard through a separate soft board.
After the dismantling, I don't want to know which cameras and batteries are selected which vendors have been selected?
The rear 13 megapixel camera model is Samsung S6KE72XX, six-piece lens, support 2x optical zoom.
8 megapixel front camera model is Samsung S5K4H5YC, five slight lenses.
The iris recognition camera consistent with Samsung Galaxy Note9, for Samsung S5k5f1sx, three-piece lens.
The screen is 10.3-inch Super amoled full screen, the resolution is 2560x1600, the manufacturer is Samsung, the model is AMSA05RB01.
The battery is 7300mAh lithium-ion battery, which is designed with a dual-core, and a plastic frame is convenient to replace.
Finally, look at which chips have been used on the motherboard.
The main IC of the motherboard (below):
Red-AKM-AK09918-electronic compass
Yellow-Ti-BQ25898-circuit protection chip
Green-Qalcomm-WCN3990-WiFi / BT chip
The main IC on the back of the motherboard (below):
Blue-Qualcomm-WTR5975-radio transceiver chip
Red-Samsung-Klucg2k1ea-64GB flash chip
Orange-Qalcomm-MSM8998-Qualcomm Snapdragon 835 processor
Yellow-Micron-4GB memory chip
Cyan-Qallycomm-PM8005-Power Management Chip
Green-Qallycomm-PM8998-Power Management Chip
Purple -stmicroelectronics-six-axis acceleration sensor + gyroscope
红 -QUALCOMM-WCD9341-audio codec
Brown-Samsung-S2MU004X-Power Management Chip
Black-Ti-TPS65630A-screen drive chip
The logic, Memory, PM, and RF chip information used on the motherboard are shown in the table:

Summary:
The Samsung Tab S4 machine has a total of 34 cross screws and structurally stable. The motherboard is heat dissipated by a heat dissipated copper foil attached to the back cover. The battery is designed with a dual-core, and the peripheral adhesive paper is fixed with a circle of plastic frames, which is convenient for disassembly replacement. The rear cover is glass material, fixed with rubber and medium frame, easy to contaminate the fingerprint. Although the entire accessories and chips that are not allowed to compare with the flagship machine, it also has a better accessory.
