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

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.
