Introduction
Galaxy Tab 3, tearing down just for the fun of it. Why? Because we can do it?
What you need
Video Overview
-
-
Technical Specifications
-
1 GB of RAM
-
1024 x 600 - 7 inch display
-
16 GB flash memory
-
Before you begin, remember to place the screen side on a smooth surface (I got my screen scratched while opening it on a rough table (Ouch!)
-
Using plastic opening tools and a spudger, look for either the micro SD cover or the SIM cover and open it. You will be able to identify a tiny little gap just enough for the plastic opening tool (wedge) to go through
-
Go around the device with the tool gently. Your ears will be able to tell when the plastic catch detach itself from the main body by listening for "clicks"
-
-
-
Once the back cover has been detached, you might want to detach the battery first to lighten the Tab's body when flipping around
-
Unscrew the batteries with Phillips #00 Screwdriver
-
-
-
Removing the back cover exposes the PCB antenna on the plastic main body
-
2.4 GHz flexible PCB antenna for WiFi and Bluetooth
-
GPS flexible PCB antenna
-
-
-
Opening the back cover reveals more secrets
-
Right Speaker information: LT02 AAC V4 1-3 Le A3626 A1
-
Left Speaker information: AAC LT02 V4-2 #2-1 A3620 A1
-
Removing the battery exposes the LCD-Shield pair manufacturing number GP3100/3110/3113
-
-
-
Unlike the Tab 2 teardown, the motherboard on the Tab 3 isn't that easy to remove compared to its predecessor.
-
Using a Makerbot wedge (as my plastic opening tool), gently go around the corners of the screen to unsnap the side body from the main body of the device
-
-
-
-
Unscrew the motherboard (shape doesn't look much different from its predecessor) and remove it from the main body (LCD's body). With the motherboard free, we get a look at all the chips onboard
-
Marvell Avastar 88W8787 WLAN/Bluetooth/FM Single-Chip SoC
-
Samsung KLMAG2WE4A-A002 16GB NAND flash & eMMC
-
Power Manager 88PM812 (1205-004832), Marvell part 812-00D0E-319AP
-
Unknown 09529 P47A1G CSSP AL3VX 1320 SG
-
DDR2 SDRAM MT42L256M32D2LG-18, Micron part 3JA78 D9QJX, possibly 1 GB
-
Marvell's PXA986 SoC (with dual ARM Core Cortex A9, GPU, Modem Processor, & DSP) possibly seats underneath this part just like its predecessor's design

-
It's time to take off the rest of the peripherals
-
First stop, the 3G and GSM antenna
-
Next, these tiny speaker boxes
-
Then the side buttons, earphones jack, vibrator motor, earpiece speakers, back camera, front camera + IR + proximity sensor, noise cancellation mic+side buttons,

Here's some photos that I have missed out. My apologies to the chaps on the comments section below for being a little late for my reply :)
-
Now if you are lacking an iOpener tool from iFixit or a heat gun, you can improvise! Just fill a huge water proof plastic bag with boiling hot water; rest it on top of the screen for 2 minutes. [Credit goes to Felix Last for his advice]
-
Shift the bag slightly to reveal the weakest point on the touch panel (usually at the middle) and with the help of a spudger, attempt to slot in gently for an opening. Just like the previous steps, go around it gently and once all the glue edges are up, lightly lift it up
-
Last I check on ''this site'', there are good load of shipments available for order from China
-
-
-
The battery reveals to be a 3.7 V, 4000 mAh type. Manufactured by Samsung SDI Vietnam
-
Display Controller Board. The LCD panel ID: LTN070NL01 registered on Samsung's Product Selection Guide . It seems that the entire LCD is replaceable (without the LRX4211 controller chip); according to this site, they do have stock for it.

The Samsung Galaxy Tab 3 7.0 is an easy device to disassemble. Absolutely no hassle, just a lot of glue you have to really take note of (in case you may use too much force)
