$100 LY-706 MID Android tablet teardown

1 of 65

  • Want a tablet, but don't want to spend $500 for an Apple iPad or Samsung Galaxy Tab? Then you might be tempted to purchase one of the many $100 Android tablets that are floating around the Web. These low-priced devices offer features similar to their higher-end cousins (touchscreen, built-in camera, and Wi-Fi). But, what's really inside a $100 tablet? We wanted to find out. So, we bought one from a site called FocalPrice.com -- the LY-706 MID Tablet Pad Netbook. Follow along as we take a peak at the hardware inside this low-cost tablet.

  • As of this writing, FocalPrice lists the LY-706 tablet at $97.99 (US) with free shipping. The device has a 7-inch TFT-LCD (800x480 resolution) with resistive touchscreen, built-in speakers and microphone, and a 1.3MB front-facing camera. Inside the LY-706, you'll find a VIA MW8505 CPU, 2GB of NAND flash storage, and 256MB system memory. It also supports Wi-Fi.

    The LY-706 comes with Android 1.6 installed.

  • Along the bottom of the LY-706 are the speaker grills, 3.5mm headphone jack, 30-pin connector, microSD card slot, and power connector.

  • I've seen LY-706 devices with black and white back covers. Our unit has a shiny black one.

  • One of the strange things about the LY-706 tablet is the lack of identifying marks. Other than model number and input power voltage, there are no other markings that identify the device. And despite looking, I was never able to determine who actually assembled the LY-706.

  • The back case cover is held in place with two Phillips #0 screws located along the bottom edge. The first is clearly visible.

  • The second external case screw is hidden behind a small white sticker with the markings QC.

  • Once I removed the external screws, the display assembly immediately popped up from the back cover. This was one of several occurances that illustrated the LY-706's poor assembly.

  • Using a thin metal blade, I was able to pop the back cover away from the display assembly.

  • As I popped off the back cover, the speaker grils (thin pieces of plastic) began to come loose from the display assembly.

  • Instead of having metal or even plastic speaker grills attached to the back cover or integrated with the speakers, the LY-706 uses extremely thin pieces of pliable plastic. This was the second indication that the device's construction wasn't on the same level as the Apple iPad or Samsung Galaxy tab.

  • With the back cover removed, we get our first look inside the LY-706 tablet. The batteries, main PCB, and a few secondary PCBs are clearly visible.

  • As I removed the LY-706's back cover, I heard something rattling inside. The culprit was a small Phillips screw that should have been helping hold the main PCB in place.

  • Inside the LY-706, we find the main PCB (right side), a small PCB the holds the camera (left side), a small PCB that holds the right side buttons and microphone, a small PCB that holds the wireless chip, battery pack, and display.

    Unfortunately, many of the internal components are soldered to the main PCB. We'll need to remove them and the main PCB as a single unit.

  • We'll start dissecting the LY-706's internal components, by removing the small PCB that houses the right-side buttons and microphone. It is held to the front half of the plastic case with two Phillips screws.

  • Once the screws are removed, you can release the catch on the ribbon cable connector and lift the small PCB away from the LY-706 tablet.

  • Each of the buttons on this small PCB are labled. From left to right are the reset, volume down, volume up, and power buttons.

  • Flipping the right-side button PCB over, we see the actual buttons and the microphone.

  • Another small PCB contains the LY-706's front-facing 1.3MP camera. Unfortunately, the PCB is permanently attached to the front case. I could remove the board, but it would require breaking the connections that hold it to the case.

    I'm going to leave this PCB in place, but disconnect it from the main PCB.

  • Luckily the wires that connect the main PCB and camera PCB are not soldered to the small board.

  • Next, I'll disconnect the other end of the thin ribbon cable the connects the right-side button PCB to the motherboard.

    We've already removed the right-side button PCB, but this ribbon cable is also attached to the underside of the battery pack. Disconnecting this end may make it eaiser to remove the main PCB later.

  • Next to the battery wires, which are soldered to the main PCB, is a connector with red and black wires that run to the LCD. There are likely wires for the backlight on the LCD.

  • With all the cables disconnected, I removed the three remaining screws that hold the main PCB in place. A fourth screw had was loose in the case when I opened the LY-706.

  • The LY-706's two internal speakers are soldered to the motherboard. We'll need to separate them from the the plastic case before removing the main PCB.

    Using a thin metal blade, you can gently pry them loose from the adhesive tape that holds them in place.

  • With all the internal cables, screws, and stuck components free, we can begin to lift the LCD, main PCB, and attached components away from the front half of the LY-706's case.

  • A smaller, green PCB is attached to the front case panel and located under the main PCB. It's wires are soldered to the main PCB, so we'll need to remove it from the front case panel.

  • Unlike nearly all the smartphones and tablets I've cracked open, the LY-706 use a touchscreen made from layers of thin, flexible plastic instead of glass. Here you can see me peeling a corner of the top layer away from the front case's hard plastic edge.

  • The LY-706's battery back is attached to the back of the LCD with adhesive. Next, we'll need to separate the two.

  • There are no markings on the LCD that indicate who made it. (At least none that I could find.) But, there are a few markings on the ribbon cable and a sticker attached to the cable.

  • The LY-706 has a battery pack with two 3.7V 5.55Wh batteries. I've read several complaints about the device having extremely poor battery life. And, TechRepublic's own Mark Kaelin reported getting only two hours of battery life under normal use.

    For the record, neither the FocalPrice site nor the documentation included with the LY-706 lists an average battery life.

  • The LY-706 provides Wi-Fi support through a Ralink RT2070L 802.11n Wireless LAN USB Adapter. The RT2070L appears to be one of Ralink's older, discontinued chips.

    Oddly enough, the small PCB to which the IC is mounted has the markings for the Ralink RT3070--one of the company's newer Wi-Fi ICs.

  • The LY-706 has a single Samsung 2GB NAND Flash chip (K9GAG08U0M) for storage.

  • The LY-706 is powered by VIA Technolgoy's WonderMedia WM8505 ARM-based CPU. Unfortunately, I wasn't able to find a clock speed for the specific chip used in this device. I've read reports of number ranging between 300MHz and 600MHz.

  • The LY-706 has two Hynix DDR SDRAM modules (HY5PS1G831C). According to the product specs, the device has 256MB of system memory. But according to Hynix's online documentation, these modules only come in 1GB and 2GB configurations.

  • The LY-706 or MID 706 tablet was a cinch to crack open. It has standard Phillips screws and an easy-open case.

    So how does the $100 tablet compare to the likes of the Apple iPad or an Android device, such as the Samsung Galaxy tab? Honestly, it doesn't.

    It has an underpowered processor (even for Android 1.6), the flimsy plastic touchscreen feels cheap, and overall build quality is just poor.

    But then again, comparing the LY-706 to the iPad is like comparing apples and oranges. They really are two completely different animals.

    Perhaps a better question is whether the LY-706 is worth $100. Unfortunately, I don't think it is. I think it's worth about $50. At that price, it actually makes a decent ebook reader or MP3 player.
