Being Verizon’s latest touchscreen offering, we gave the Motorola Krave a spin and – of course – a good tearing down. With Motorola dying down so fast, it’s natural to want the now-underdog cellphone giant to succeed. In fact, with this phone, Motorola seems willing to give their Western cellphone lineup a change, incorporating some styling from its Asian counterpart (Motorola MING) and capacitive touchscreens for the touch-hungry Western market. Not only is there one main touchscreen, the cover also contains a capacitive circuit.
How does the Motorola Krave fair in our review and teardown? Find out after the break.
Using the Motorola Krave is akin to sitting in a comfortable canoe with a few holes. You can keep paddling, but eventually you have to either cover up the holes or scoop that water up. There are some greats and gripes, but in the end, the weighted averages sway more to the gripes.
Motorola Krave Review
Greats
The phone comes with a few interesting quirks. First, the unique feature (with questionable practicality) is the device’s ability to use the touchscreen with the clear plastic cover closed. The way this is implemented is through an ingenious, thin mesh that’s able to sense your fingers position (shown below – look closely!). It also seems that this mesh is actually used to transmit power and signals to the earpiece, as there is no other connection to it, which brings us to the second unique feature. Taken from the Motorola MING, the Krave’s earpiece is made to appear wireless. It’s a very interesting concept and it definitely has its appeals. Motorola’s engineers definitely have kept its stride with this implementation, as the call quality sounds great and is capable of pretty loud and obnoxious noises.
The other really good thing about the phone is that it’s built like a tank. It’s rubbery sides give a really good, comfortable feel to the device, and there’s very little give to it. The cover hinge is solid and feels strong enough to tank anyones robust flips. The interesting thing to note is that the speaker actually hits the screen when its closed. Cheers to hoping it doesn’t actually scratch it.
Finally, sideloading music onto this phone is a breeze. Sure, Verizon’s got this MTP structure harped down people’s throats because it enables hot plug and play, but transferring your music is easy enough (and very quick!) through Windows Media Player’s sync option.
Greaipes
Sure we made up that word, but Motorola seems to embody this awkward word. Being a mix of greats and gripes, we were forced to implement this section. So here it is: the greaipe of the phone, is it’s capacitive touch screen. It generally responds well (as is generally the case with a capacitive screen), but it has its infuriating moments. Menus move along with with your finger, and haptic feedback lets you know your choices as you press them. They’re quick (most of the time) and it works very well with the browser. Dialing is also a breeze with quick thumb touches.
Unfortunately, it’s one of the most annoying things to use. Typing on its landscape keyboard is nigh impossible due to the cover’s awkward placement (seriously, how did they let this pass usability tests?). Also, there are moments when the phone lags like no tomorrow. This is possibly more of an OS and a processor issue than its touch capabilities, but it still harps down on the phone’s usability. Lastly, these guys need to put some coating on the screen. When you first get the phone, a gigantic sticker is put on the phone, which causes the screen to be sticky. Even after a lot of use, the screen never becomes slick like its other famous touch-rivals.
Gripes
Even though sideloading music is great to use, playing the music through its integrated media player isn’t the most pleasant implementation. The buttons are hard to press accurately and that’s a major pain to anyone looking for a pleasant music playing experience. Also, the interface, instituted by Verizon’s team, is truly disgusting. The red and orange colors are not in the least bit interesting, and it’s really a pain to use day after day.
The other major gripe is the phone’s performance. Phone browsing is relatively decent (compared to non-smartphones) on Verizon’s EV-DO network, but everything else is sluggish and annoying to use. Even the general menu screen lags once in a while.
Conclusion
In the end, the gripes and usability issues cause this phone to be a big frustration when used day-to-day by a heavy user. Its not a smartphone by any means, nor is it meant to be; but when the consumer-focused mindset of this device is coupled along with the device’s incapability of texting, limited browser, and limited media capabilities, it really shouldn’t be your first pick of a phone.

Motorola Krave Teardown
Here we go! This phone was actually even more of a pain to open than the Nokia N95. This is due to the multiple layers and multiple connections made. Shielding was an issue, but wire snippers made quick work of that. In the end, you’re left with a decent and relatively simple PCB. We’ve drawn a block diagram to lead you through the components.
First thing to notice is the Qualcomm MSM6575 chip used. It’s got an integrated audio codec which feeds signals to the earpiece, dedicated speaker, and headset jack. Qualcomm also seems to have several design wins with this phone, since its entire RF and power management ICs are all Qualcomm marked. It’s got a separate receiver and transmitter (RFR6500 & RFT6150 respectively), which is a little bit odd considering the board space that two ICs use. The Krave’s power is managed through Qualcomm’s PM66508. It’s also got a MediaFLO receiver, Qualcomm MBP1610, for all that streaming video goodness.
The Krave uses a Cypress Semiconductor part for its West Bridge components, which explains the quick music sideloading noted earlier. A quick Google search on its part number: CYWB0124AB brought up interesting articles on how its West Bridge parts independently route data from the USB interface onto a MicroSD card.
Next thing to notice is the two capacitive sensor ICs, both from Quantum Research Group (QRG 6G4670 for the main screen & QRG BF7741-1 for the cover). As noted earlier, the nigh-invisible mesh on the cover senses the location of the touch. There is also one on top of the main LCD screen (Samsung).
Yesterday’s teardown received a lot of hype. We’re glad we could cater to what many of our readers obviously enjoy! We’ve been working hard with “our friends in high places” to really figure out what makes this thing chug.
The device PCB is covered in what we call “cans” which provide ESD, heat and RF interrupt protection. In order to see what’s on the board, Dr.Wreck has to carefully remove each one by melting away the solder points. This is not an easy process as we try our best to keep the device in fully functional order.
On that note, many of you have actually challenged us to reverse yesterdays directions and put this thing back together! This is an entirely possible feat, had we not fully removed the shields. Even so, we’ll be putting this device back together (shields and all) in an attempt to prove that you can ENTIRELY disassemble a device to bare IC’s and logic board and still re-assemble for full functionality.
We also wanted to take a moment to talk about the progression of mobile devices (note that in this image the Droid’s PCB is fully naked!). On the right side of this photo we have an old “nameless” Nokia device. Back in the day, a devices size was limited by the PCB and the allocation of it’s parts. On the Droid, there is so much integrated functionality that the PCB is actually one of the smallest parts on the device. Of very interesting notice, the screen on the Nokia device is smaller than the PCB. The absolute OPPOSITE is true on the Droid.
Dr.Wreck has that wistful glean of the past in his eye…. sigh…
Here we have the functional Block Diagram put together by Dr.Wreck for the Motorola Droid.
This device isn’t that much unlike the Palm Pre. The OMAP 3430 is a very promising platform that features the same Imagination Technologies POWERVR SGX graphics core. However, when fully considered there really isn’t much that compares in terms of full scale integration.
Strangely enough, the device backed by one of Verizon’s largest ad-campaigns as the iPhone killer only has 256MB of RAM and 256MB of integrated NAND storage. How will the Android platform ever contend? Well, Dr.Wreck is currently working on his review… stay tuned for that insight. In the case of the Droid, both memories are provided by Japanese Toshiba. The RAM is stacked on top of the OMAP Applications Core.
Here we have the top of the logic board. Unfortunately, it is difficult to identify many of the larger IC’s on this side. Thankfully, Dr.Wreck has X-ray vision and the ability to feel an IC in order to determine it’s functionality.
We can see the TI TWL5030 PMIC which offers integrated USB, Audio Codec and control over that big 1420mAh BP6x battery. We also see the RF multiplexer’s – one from both AVAGO (FEM7758) and Triquint (TQM613029).
Unfortunately the WiFI/Bluetooth chips are unmarked. If any readers have industry knowledge or an opinion of what these chips might be, feel free to share – that’s what it’s all about!
The underside of the PCB reveals a fairly big surprise – the fairly rare QSC6085 BaseBand with integrated GPS and transceiver functionality. We also see the location of the OMAP processor, cleverly buried underneath the un-distinguishable Toshiba RAM. Not only did Motorola not want us to take this device apart, they didn’t want us to find out what makes it run!
Another really interesting tidbit that pops up on the underside of the board is the Toshiba memory with hand-written markings. More interesting is that these markings appear to say “s”, “2″ and “p”! Here at phonewreck, we’ve been contemplating this phenomena and have come to the conclusion that Sanjay (Co-CEO of Motorola) must have personally signed each chip that went into the Droid. More or less a mark of approval we suppose.
In all seriousness though, this is probably the marking of a sample part. Why in the world is Motorola releasing production devices with sample IC’s? This is only conjecture, but the Droid is supposed to do a multi-million unit run. Hopefully there aren’t quality issues relating to device longevity! Am I right?! Am I right?!

And that’s it! Thanks to everyone who e-mailed in with their support from yesterday’s entry!
Until Next time, KEEP WRECKING!Ladies and Gentlemen, the moment you have all been waiting for has arrived. Dr.Wreck has fully disassembled his Brand New Motorola Droid from Verizon.
Taking this device apart is NO EASY TASK! Motorola has worked wonders to make this thing as surprising and delicate as possible. Dr.Wreck loves challenges, thus he commends you oh, Motorola engineers!
The first thing you’ll need to do is remove the back cover and battery. Grab your trusty T6 and remove both the silver and black screws from the rear of the chassis. The silver screw holds the PCB in place. The Black Screws hold the back plate on the screen portion of the device.
Finding the next set of screws was a challenge. Dr.Wreck noticed a small wedge under the plastic piece above the google label at the very back of the phone. Here you’ll need a pin or very small prying device to get underneath and lift it away.
It’s important to be careful with these steps as these plastic pieces tend to be slightly brittle. Once you pull this piece away you will reveal another two T6 screws. Remove them.
Aha, there’s another one placed underneath the google label and camera lens cover! Very sneaky Motorola.. Very sneaky indeed…
Now comes the most frustrating part…
The final 3 screws are located underneath that faux gold grating that covers the bottom of the battery door. Use a pin, wedge or staple remover to pry this up. Remove the 3 final and amazingly disguised T6 screws to free the Droid’s PCB.
Now, use your wedge to pry out the clips on the back part of the frame.
Tada!!!
Unfortunately, we’re far from done. There is still one more silver T6 locking the logic board in place. Remove that.
Now we need to pop off those flex cables that connect the device to the screen.
You can now flip away the PCB. And remove the remaining flex cable.
Now that the PCB is free, all that’s really left to do is remove the screen and slider mechanism. This can be done by pulling at the black plastic frame that creates the upper border for the device.
And that’s it! Interestingly enough, the sliding mechanism is essentially just two rails that are embedded within the screen portion of the device – this is the simplest sliding mechanism we’ve ever seen! Stay tuned for the review to see what Dr.Wreck and Dr.Phone actually think about it!
Ladies and Gentlemen, the moment you have all been waiting for has arrived. Dr.Wreck has fully disassembled his Brand New Motorola Droid from Verizon.
Ah yes the BlackBerry Tour 9630 – RIM’s answer via Sprint and Verizon to the very successful Bold (available on GSM networks).
Design wise, the Tour shares similarity with all 3 of the current and very successful BlackBerry devices available on the market. It’s got the shape of the storm, the screen of the 8900, and the keyboard of the Bold. In Dr.Wreck’s humble opinion, this device takes all the best physical design features from the current roster, tosses them in a pot, and mixes up a delicious cup of chowder. This device has good weight, good size, and good functionality (screen, keyboard, software).
A lot of you have had difficulties with the trackball. Luckily RIM has disbanded this gosh-forsaken mechanically unstable and frequently unreliable piece of junk for the new optical trackpad we see on the Gemini and the newly announced 9700. Gone are the days of blowing on your trackball in hopes that a gust of bad breath can fix it!
Dr.Wreck has gone ahead and ripped this thing apart to perform a full teardown and analysis. Click through for all the juicy details!
The first step to taking your Tour apart is to remove the battery cover and battery. There you will see 4 hex bolts embedded in the plastic frame. Grab your T6 for the best fit. Remove all 4 screws but take note, the screw about midway up the right side of the device has a white sticker covering it.
After you remove the screws, you are NOT ready to pull this cover off. Don’t pull, pry, push, or break. There are six screws holding the device together – the top two are hidden and getting to these can be somewhat difficult.
To get to these well-hidden monsters, you need to pry away the plastic piece with the BlackBerry logo and earpiece grating. Dr.Wreck uses a staple remover for all of his leveraging needs – he recommends you do the same.
This piece is adhered with double-sided tape. Pry it away but be careful not to crack the plastic!
Voila! Now use your T6 to remove the screws you just found underneath – pull away the rear cover and reveal the PCB!
It’s important to keep in mind that your PCB won’t look like Dr.Wreck’s. In order to identify all of the integrated circuits we had to remove all of the “cans” (Metal shields) that provide heat and ESD shielding. Removing these shields is a bit of an art, we’ll keep that secret to Dr.Wreck’s dainty hands!
You can now pop off the flex cable tabs like Dr.Wreck is in the image above. These connectors are fairly robust however – delicacy should be practiced. You will also need to pop off the antenna which is located at the top right of the PCB.
You should now be able to flip the PCB vertically to reveal the underside (where the real brains are!). There are 3 flex cables attached to the PCB. These are used for the LCD, Trackball, and keyboard. Pop them off to fully remove the PCB!
This is a good point to discuss the design of this device further. RIM has opted for a “floating” PCB design. This both saves money and makes these devices MUCH easier to take apart and service. The drawback is with the trackball (which we will see/discuss in a moment).
As soon as you pry away the chrome, face-plate, and device border, the keyboard and trackball fall apart. This is where the design flaw lies that has created a massive warranty issue for the carriers. On the Bold, the entire track-ball module clips into the PCB via a small malleable metal frame. This piece was totally discarded on the Tour and consequently the ball more or less floats inside of the device.
If your trackball stops working, put a thumb on either side of the module and press firmly and evenly across the front of the device. This should reset everything and temporarily let you use the device again.
Now – for the reason you’ve all been reading – the Teardown Analysis. What devices make this puppy tick?! Check out the functional block diagram below.
At the core we once again have the Qualcomm MSM7600 which provides both the Baseband and Application management functionality. Not surprisingly, this is the very same core that resides in the current BlackBerry Storm. As a matter of fact, when we look further we see many other shared ICs from the same Qualcomm reference design. These include the Qualcomm PM6658 for Power Management, the RTR6500 Dual-Band Transceiver and RTR6285 RF Transmitter.
It looks as if RIM went away from CSR for Bluetooth with its decision to use the Samsung BTTM53C2RA chipset. This is not entirely the case. Delving into our resources reveal the same CSR core, disguised in a Wafer-Level-Chip Scale Package.
Looking even further we see the same USB Phy from SMSC coupled with the now BlackBerry standard MicroUSB port.
Unfortunately, the 9630 falls a fair amount short of the mark in the memory category. Sporting the ever-common Samsung MCP K5W2G1, we note that it only has a 2Gb OneNAND coupled with the 1Gb SDRAM. This falls short of the Storm however the phone really does perform admirably well – under almost every benchmark test we could subject it to (with the exception of sideloading).
And that’s all she wrote! Any comments, or questions – feel free to pop them into the comment section below! Dr.Wreck is going to be spending some time with two new devices over the next few days. Stay tuned for lots of data!
