Edit Step 1 HTC Surround Teardown  ¶ 

  • The HTC Surround takes the idea of a mobile media center to a whole new level.

  • The Surround is also among the first smartphones to use the Windows Phone 7 Operating System.

  • Technical Specifications:

    • 1 GHz Qualcomm QSD8250 Snapdragon processor

    • 448 MB RAM

    • 16 GB internal storage

    • 3.8 inch widescreen WVGA display

    • 5.0 MP camera

Edit Step 2  ¶ 

Image 1/2: The phone also sports a kickstand (a la [guide|2979|Evo]), presumably so you can set the phone down upright when you want to night-club on the go. Or to watch videos. Whatever.

Edit Step 2  ¶ 

  • To fully accommodate the phone home theater aspect of the Surround, the entire bottom half of the the phone slides out to reveal an impressive speaker array.

  • The phone also sports a kickstand (a la Evo), presumably so you can set the phone down upright when you want to night-club on the go. Or to watch videos. Whatever.

Edit Step 3  ¶ 

Image 1/2: You really don't have to use plastic opening tools to open the back cover, as fingernails will work just fine. But we like to be cautious with these things -- you never know what might break.

Edit Step 3  ¶ 

  • Through the use of plastic opening tools, the back cover of the Surround comes off easily and we get our first look at the internals of the Surround.

  • You really don't have to use plastic opening tools to open the back cover, as fingernails will work just fine. But we like to be cautious with these things -- you never know what might break.

Edit Step 4  ¶ 

Image 1/1:

Edit Step 4  ¶ 

  • The 3.7 V 1230 mAh 4.55 Wh Li-ion battery supplies power for up to 4 hours of talk time and about 275 hours of standby time.

Edit Step 5  ¶ 

Image 1/2: After voiding the warranty, removing five T5 Torx screws gets us a step closer to the goodies inside.

Edit Step 5  ¶ 

  • Want to open your HTC Surround any further? Hope you don't care about warranties. Two VOID stickers attached to the inner case screws ensure that no intrusion attempts go undocumented.

  • After voiding the warranty, removing five T5 Torx screws gets us a step closer to the goodies inside.

Edit Step 6  ¶ 

Image 1/2:

Edit Step 6  ¶ 

  • Four more Phillips screws along the edges of the phone secure the rear case to the body of the HTC Surround.

Edit Step 7  ¶ 

Image 1/3: Six pressure contacts on the bottom inner case serve to:

Edit Step 7  ¶ 

  • After a bit of prying with a plastic opening tool, the bottom inner case can be removed from the Surround.

  • Six pressure contacts on the bottom inner case serve to:

    • Connect the lower speaker to the lower motherboard.

    • Connect to what is presumably an antenna housed in the bottom inner case.

Edit Step 8  ¶ 

Image 1/2: The upper section of the inner case also has a small interconnect board to connect the speaker to the top motherboard in addition to an antenna and integrated shields for [link|http://en.wikipedia.org/wiki/Electromagnetic_interference|EMI] protection.

Edit Step 8  ¶ 

  • Some more prying with a plastic opening tool and the upper section of the inner case can be removed.

  • The upper section of the inner case also has a small interconnect board to connect the speaker to the top motherboard in addition to an antenna and integrated shields for EMI protection.

Edit Step 9  ¶ 

Image 1/2: Should you decide that 16 GB isn't enough, it definitely seems possible that you could easily swap the card out for a higher capacity MicroSDHC.

Edit Step 9  ¶ 

  • More poking and prodding reveals that the "internal storage" in the Surround is no more than a well-hidden MicroSDHC card. And they would've gotten away with it too if it weren't for us meddling kids!

  • Should you decide that 16 GB isn't enough, it definitely seems possible that you could easily swap the card out for a higher capacity MicroSDHC.

Edit Step 10  ¶ 

Image 1/1: The Surround has two [guide|1654|Nexus One|stepid=8761]-esque motherboards that are attached with a large ribbon cable spanning the gap between them.

Edit Step 10  ¶ 

  • We used a plastic opening tool to pry the MicroSDHC and SIM card slots off the EMI shield.

  • The Surround has two Nexus One-esque motherboards that are attached with a large ribbon cable spanning the gap between them.

    • This is not much of a surprise, as HTC is the manufacturer of both the Nexus One and the Surround.

Edit Step 11  ¶ 

Image 1/3: The hefty slider mechanism should hold up to years of opening and closing the speaker grille.

Edit Step 11  ¶ 

  • A handful of connectors attached to the antenna, motherboard interconnect, and display data cables stand between us and the lower half of the Surround's motherboard. Luckily, we're feeling up to the task.

  • The hefty slider mechanism should hold up to years of opening and closing the speaker grille.

Edit Step 12  ¶

Edit Step 12  ¶ 

  • Big players on the front of the lower motherboard include:

  • Like most smartphones, the Surround utilizes dual microphones to cancel background noise during phone conversations. The lower microphone can be seen near the Micro-USB port.

  • The chips are identical to those found inside the Nexus One.

Edit Step 13  ¶ 

Image 1/1: [http://www.qualcomm.com/products_services/chipsets/power_management.html|Qualcomm PM7540] power management IC

Edit Step 13  ¶ 

  • And on the back of the lower motherboard:

    • Qualcomm PM7540 power management IC

    • Skyworks SKY77336 power amplifier module

    • Audience A1026 voice processor, used in conjunction with the two microphones.

    • One of the two speakers used to project stereo sound through the Surround's speaker grille.

  • Once again, all three chips are identical to those found inside the Nexus One. If it ain't broke, why fix it?

Edit Step 14  ¶ 

Image 1/1: The motherboard interconnect cable is sandwiched between the many layers of the upper motherboard, much like on the [guide|1654|Nexus One|stepid=8767]. This technique eliminates the space requirements for thick connectors and sockets, making the final connection much thinner.

Edit Step 14  ¶ 

  • After prying a few retaining clips out of the way, the upper motherboard can be removed from the Surround.

  • The motherboard interconnect cable is sandwiched between the many layers of the upper motherboard, much like on the Nexus One. This technique eliminates the space requirements for thick connectors and sockets, making the final connection much thinner.

Edit Step 15  ¶ 

Image 1/2: This little camera shoots 5 MP stills with autofocus and records 720p video at 24 fps.

Edit Step 15  ¶ 

  • The Surround's camera is easily removable from the top motherboard.

  • This little camera shoots 5 MP stills with autofocus and records 720p video at 24 fps.

Edit Step 16  ¶ 

Image 1/2: LED flash unit

Edit Step 16  ¶ 

  • Components attached to the top motherboard include:

    • LED flash unit

    • Vibrator motor

    • Headphone jack

    • Top microphone

  • Metal plates with strategically placed holes are soldered to the front of the Surround's two speakers to direct the sound out of the fancy speaker grille, not into the phone.

Edit Step 17  ¶ 

Image 1/2: Relatively easy to remove the rear case to replace the battery.

Edit Step 17  ¶ 

  • HTC Surround Repairability Score: 5 out of 10 (10 is easiest to repair)

    • Relatively easy to remove the rear case to replace the battery.

    • Slider mechanism provides added complexity for the sole purpose of arguable audio performance gains - but makes display removal that much more difficult.

    • Unable to access the internal MicroSDHC card without voiding the warranty.

    • It is very difficult to access the front panel and LCD for replacement.
