Galaxy Tab 7.7 teardown reveals lots of Samsung's homegrown hardware

Bill Detwiler cracks open the Galaxy Tab 7.7 and finds an Android tablet packed with Samsung's own hardware.

Samsung has raised the bar on 7-inch Android tablets with its Galaxy Tab 7.7. This week, I crack open the Tab 7.7 for a look at the hardware inside.

The Galaxy Tab 7.7 has a 1.4GHz dual-core Samsung Exynos 4210 processor, 1GB of RAM, 16GB of storage, a 7.7" AMOLED display (1,200 x 800 resolution), 802.11b/g/n Wi-Fi and Bluetooth, a 3-megapixel rear-facing camera, and a 2-megapixel front-facing camera. It measures measures 7.74" (H) x 5.24" (W) x 0.31" (D) and weighs 12 ounces.

Cracking Open observations

  • Easy-open case: Despite looking a lot like the Galaxy Tab 2 7.0, opening the Tab 7.7's case required a completely different approach. Instead of starting along the tablet's edge and working my way around the case, I started in the front, inserting a thin metal tool between the front glass and edge of the back cover. Applying gentle outward pressure, I popped the cover loose from the front panel assembly. After working my way around the case, I removed the back cover.
  • Familiar Samsung internal hardware design: As with the previous Samsung tablet's that I've cracked open, the Tab 7.7 has a very clean internal hardware layout. I also like Samsung's use of snap-on connectors along the motherboard, which makes the individual components easy to detach and replace.
  • Single-piece front panel/display assembly: My only complaint about the Tab 7.7's design is front panel and display assembly design. The two components are either fused into a single piece or held together with strong adhesive. If the screen was held in place with screws, you could easily replace a cracked front panel without buying a new display and vice versa.
  • Replaceable battery: The Tab 7.7's 5,100 mAh battery is held in place with screws and attached to the motherboard with a snap-on connector. Once the case is removed, you can easily replace the battery.
  • Packed with Samsung hardware: Not only does the Tab 7.7 have a Samsung Exynos 4210 processor, the unit's LTE baseband processor, DRAM, and flash storage module are all Samsung chips.

Bottom Line

Given all the Tab 7.7's high-end hardware, it's not surprising that Samsung has given the unit a high-end price. As of this writing, you can buy the Tab 7.7 for $450, with a two-year Verizon contract. Without the contract, the price jumps to $700.

Samsung definitely set the standard for 7-inch tablets with the Tab 7.7. It's thin, powerful, has a beautiful display, and 4G support. But the high price and two-year commitment may scare away some buyers.

7.7" AMOLED display (1,200 x 800 resolution) or 7" Plane to Line Switching (PLS) display (1,024 x 600). Which is it? Are there any other specs that are listed incorrectly?
