Galaxy Tab 2 7.0 teardown reveals efficient hardware layout and replaceable battery

The Samsung Galaxy Tab 2 7.0 Android tablet has a case that's easy to open, clean internal design, and replaceable battery.

Samsung is jumping into the budget tablet market with a 7-inch device that looks nearly identical to the company's Galaxy Tab Plus, but costs $200 less. This week, I crack open the Samsung Galaxy Tab 2 7.0 Android tablet.

The Galaxy Tab 2 7.0 has a 1GHz dual-core Texas Instruments OMAP 4430 processor, 1GB of RAM, 8GB of storage, a 7" Plane to Line Switching (PLS) display (1,024 x 600 resolution), 802.11b/g/n and Bluetooth, a 3-megapixel rear-facing camera, and a VGA front-facing camera. It measures measures 7.6" (H) x 4.8" (W) x 0.41" (D) and weighs 12.1 ounces.

Cracking Open observations

  • Easy-open case: Samsung didn't use any hidden or tamper-resistant case screws on the Tab 2 7.0. To open the device, you just pop off the back cover.
  • Super-clean hardware layout: Like the Galaxy Tab 8.9 and 10.1, the Tab 2 7.0 has a clean internal hardware layout. There's a single circuit board, each component is attached to the main PCB with a snap-on connector, and with the exception of the display, nothing is held in place with adhesive.
  • Replaceable battery: The Tab 2 7.0's 4,000 mAh battery is held in place with screws and attached to the motherboard with a snap-on connector. Once you've removed the back cover, replacing the battery is a snap.
  • Same processor as the Kindle Fire: As for the tablet's engine, Samsung used a Texas Instruments 1GHz dual-core 4430 OMAP processor, which is mounted under the unit's 1GB RAM chip. This is the same processor Amazon used in the Kindle Fire, but a step down from the Galaxy Tab Plus' 1.2GHz Exynos 4210 processor.

Bottom Line

How does the Galaxy Tab 2 7.0 stack up against the other 7-inch tablets, like the Galaxy Tab Plus and Kindle Fire? As Erik Franklin pointed out in his CNET review, this tablet "offers an excellent value and a full Android 4.0 experience that no other tablet can currently match for the price."

At $249, the Tab 2 7.0 is $50 more than the Kindle Fire, but the Samsung device has two cameras, you can expand the device's memory to 32GB using a microSD card, and it functions as a TV remote. On the other hand, the Fire puts the power of Amazon's online store in the palm of your hand.

Comparing the tablet to other 7-inch devices is a bit trickier. Does it have the processing power of the Galaxy Tab Plus ($349 for 16GB and $449 for 32GB)? No. But the user experience is still good and you get a lot of bang for your buck.
