First Look: LG G3 Teardown


Month after month of speculation and rumors have finally led us here, and uBreakiFix has the sincere pleasure to provide you with the first LG G3 Teardown! Take a look inside LG’s new flagship powerhouse, the G3.

For this teardown, we will be using the Samsung Galaxy S5 and HTC One (M8) for comparison.

First, let’s review the specs: 

  1. 5.5” True HD-IPS LCD (1440 x 2560, ~534 ppi)
  2.  13 MP rear camera with 2160p@30fps video; 2.1 MP front camera with 1080p@30fps video
  3. Highly touted 1W loudspeaker with boost amp
  4. 2.5 GHz quad-core Snapdragon 801 processor
  5. 2 GB (16 GB model) or 3 GB (32 GB model) LPDDR3 RAM
  6. LTE, NFC, Bluetooth 4.0 LE, Wi-Fi 802.11 a/b/g/n/ac dual-band
  7. MicroUSB 2.0 (SlimPort)
  8. Li-Ion 3000 mAh battery

Now that we know what we should see under the hood, let’s get down to business.


Starting on the outside front of the phone we see the 5.5” LCD, ear speaker, front camera, and infrared and proximity sensors. On the back is the highly-advertised 1W loudspeaker, rear camera and dual-LED flash, and power/volume buttons. Along the bottom a MicroUSB 2.0 SlimPort, and 3.5mm stereo jack.

Alright, enough gawking, time to see what makes LG‘s new G3 flagship tick.


We begin with the ubiquitous battery cover. Once removed we see the Li-Ion 3000 mAh battery, larger than the Galaxy S5 at 2800 mAh or the HTC One (M8) at 2600 mAh, the lowest capacity of the three (surprisingly low for not being user-removable). Built into the battery cover is the wireless charging interface. Even with the extra mAh we wouldn’t be surprised if users didn’t see the benefits as the new and improved Quad HD screen likely draws extra power.


Next we remove the lower back housing which contains the loudspeaker assembly.


After that, the upper back housing is removed exposing the contacts for the power/volume button flex as well as the phase detection/laser autofocus module.


Once the button cover is removed from this housing piece we can see this flex assembly.


Finally we get to see the motherboard. One of the first differences we notice is that there is only one small daughterboard, unlike the G2 which had another controller board split along both sides of the motherboard.


A few flex connectors later and we are able to remove the motherboard, the only other board in the phone located at the bottom is most-likely for grounding.


Directly above that board are the flex connectors for the LCD and digitizer which is assisted by a Synaptics 93528A touchscreen controller. This absolutely stunning LCD has been advertised as a Quad HD display and sports a staggering 534 ppi pixel density which blows away the S5 at 432 ppi and the One (M8) at 441 ppi.


We can also see the 13 MP rear camera (4160 x 3120 pixels), which has been one of the major selling points for the G3 and with 2160p video resolution at 30fps, it’s no wonder why. Looking at the competition we see the S5 with very similar resolution at 16 MP (5312 x 2988 pixels) and 2160p@30fps video, and the One (M8) with dual 4 MP (2688х1520 pixels) with 1080p@60fps video.

Also visible is the front camera is 2.1 MP, slightly better than the 2 MP in the S5 but drastically less than the One (M8) which brings a 5 MP front camera to the table.


Lastly, adhered directly to the back housing are the 3.5mm headphone jack and the ear speaker.


What’s that odd looking component on the right? Well this is what we call an antenna, they were used on cell phones many years ago for better reception. This one however is for TV tuning although it is not likely the US version of the G3 will include a TV tuner antenna.

Once we remove the metal shields from the motherboard we are able to see many more chips, some of which we have already identified.


On the top side of the motherboard we see:

  1. (Orange) Toshiba THGBMBG8D4KBAIR 32 GB on-board NAND flash memory


On the bottom side of the motherboard we see:

  1. (Purple) Broadcom BCM4339 5G WiFi combo chip
  2. (Teal) Avago ACPM-7700 power amplifier module
  3. (Red) Qualcomm WTR1625L RF transceiver
  4. (Green) Qualcomm WFR1620 receive-only companion chip
  5. (Orange) SK Hynix 2GB/3GB LPDDR3 RAM layered on the 2.5 GHz quad-core Snapdragon 801 processor.
  6. (Yellow) ANX7812 USB SlimPort Tx IC
  7. (Blue) Texas Instruments BQ24296 battery charge management and system power path management chip.

Overall, initial impressions are that this is a beautifully engineered phone. The use of several contact-style connectors instead of flexes will certainly reduce repair time and the location of the LCD/digitizer connectors give the G3 a much higher repairability factor than its predecessor; on a scale of 1 to 10, the LG G3 scores a respectable 8/10.

    Great test, one concern though.

    It seems like most of the bent phones out there are bending near the volume button. Why did you choose to not apply pressure to that area? If that is a structural weak area, as it seems it might be, isn’t it worth testing?

    Maybe you tested it independently and didn’t think it was worth putting in the video? If so I’d love to know the results.

  • sarstube

    can we see pics of all the phones lying a flat surface out of the machine? and at what weight did you start to notice a deformation?

  • DasithWijesiriwardena

    The note 3 bends back into flat in the tests. Can you show after photos?

  • Tim

    The question is, can you bend it back?!

  • Sledgy

    It might also make a difference where the pressure is applied. The iPhone6 seems to bend just below the volume buttons. Applying pressure there might bend it under less pressure.

  • Charlie

    Can you place the load on the iPhone 6 Plus near the volume buttons where this video found it to be the weakest?

  • Ashish

    Test is not done in the right way. the two support points at the bottom should be as far away as possible. here you are doing bend test on only 80% of the phones height. I am sure Iphone 6 will deform to a great extent. check this link, iphone deformed just by hand —

  • drnemmo

    The problem here is not flexibility, it’s resilience. iPhones aren’t resilient, they don’t go back to their original shape. Plastic, on the other hand, is inherently resilient.

  • david

    100lb of force applied over an inch wide portion of the phone does not seem to be quite real world conditions. I will be curious to see just how many phones are effected by this in everyday use. However, thanks for the testing, as I have been reminded to be careful, just as I was with other phones, not to subject my iphone to extreme abuse.

  • Gentleman Gamer

    I’m sure this makes the dudes with bent phones feel MUCH better…

    • babushnik

      you mean all 5 of them…. out of ten million…

  • georjamdak

    I honestly am shocked.. no wait I’m not shocked over the iPhone bend controversy because i know how irresponsible people are. I mean seriously when we were kids we had fisher price stuff that was made tough for us because we were children who didn’t know responsibility yet but we are now adults with $700 phones that aren’t made to be sit on!! Do people need a company to just make tough ugly electronics that are nearly unbreakable because of the lack of being a responsible adult? If you are that bad then there is outterbox… i myself have not used a case on any of my phones since 2007 including all the iPhones. Never had a problem or drop and i am extremely happy with my iPhone 6 plus, best phone out there right now and all the professional reviews and tech sites are posting similar rave reviews as well

  • Bre

    Here is the point everyone, this only proves one thing, all phones will bend break etc. Even if we did the same test in the machine on the new Samsung coming out that is made with more metal as advertised then you are going to see the same or worse with the Samsung. The ones that get hurt the worst from all this Bendgate crap is the consumer reason is the companies instead of loosing money on returns because we as adults sit on our phone in our pocket the companies will stop making skinny phones and make them more thicker and stronger. This is all stupid dumb and retarded this even started, but now that it has started Samsung should get the same test done on their new released phones as well. Curious how they will turn out in the bend test??????

  • babushnik

    one test is nice… but… that’s it… it just one test…. maybe the iPhone does slightly worse on this test…. but slightly better in another…
    overall… i tend to like the iPhones because of the operating system and the eco system…
    but… i buy the extra applecare cuz i know that over 2 years i don’t want to have to worry about dropping it or accidentally wearing the tightest jeans possible and doing calisthenics with the 6+ in the pocket…lol

  • philiptomlins

    I would really like to see the same test done after the iPhone has been playing a Device intensive game while chargeing so it is nice and hot and then she how much pressure it can take as if you was playing in you phone on charge then put it in your back pocket and went in car would it be softer then when cold


    Where is the Voltage Regulator Module on an LG G Flex located?


    Please anyone! Is it possibly on the charger port dock board?

  • Dom

    If i remove the Toshiba THGBMBG8D4KBAIR 32 GB on-board NAND flash memory can i install it to another mother board to be able to retrieve pictures?

  • Angel Andujar

    Thanks for share this. Now I know for sure what’s going on with the static using my Rode VideoMe Mic in the LG G3. The transceiver are very close to the microphone. Anyone know any other LG built with those transceivers far from the 3.5 jack?
