We snagged an HTC Evo 4G at Google I/O before it went on sale to the general public. We turned it on, played with the gorgeous screen for the drive home, then immediately relegated it to the carving table.
The Evo 4G was wonderfully easy to disassemble, which should make servicing/repairing the phone very simple. Even so, HTC managed to avoid "ghastly" visible screws by using a removable back panel. Once the panel was removed, we were able to access the six T5 Torx screws and underlying components using a bit of care and precision.
* Removing the glass is not terribly difficult. This is great news for those unfortunate enough to drop their shiny phone and crack the glass.
* Like most reasonable phones, changing the Evo's battery is a snap. All you have to do is remove the back cover and unplug the battery.
* The 3.7 V, 1500 mAh rechargeable Li-ion battery contains 23% more capacity than an iPhone 3GS, 15% more than a Droid Incredible, and 7% more than a Nexus One.
* Look out! There's a liquid damage indicator on the battery's top edge -- a first that we've seen. Of course, you can just replace the battery if you douse the Evo in water. There are other liquid damage indicators on the phone, however, so you can't fool the manufacturer that easily.
* The Evo's internal frame houses the stand, antennas, LED flashes, and speaker, and connects to the logic board via several ribbon cables.
* The dual LED flash assembly consists of no more than two LEDs soldered to a small interconnect board.
* The forward facing 1.3 Megapixel camera lifts right out of its enclosure in the top portion of the Evo 4G.
* Big players on the logic board include:
* Broadcom BCM4329 integrating Wi-Fi, Bluetooth, and FM connectivity to provide speeds up to 50 Mbits/s in 802.11n.
* Sequans SQ1210 RF combo chip.
* Qualcomm's QSD8650 Snapdragon processor.
* Amtel's AMT224 Touchscreen controller.
* Qualcomm's RTR6500 CDMA2000 transceiver with GPS.
* Qualcomm's PM7540 power management IC.
