LG G3’s first teardown reveals how easy it is to fix

by: Edgar CervantesMay 30, 2014


You have seen us get our hands all over the LG G3, compare it to multiple competitors and giving you our very own firm opinions on LG’s device of the year. Our friends at UBREAKIFIX are also not afraid of getting personal with the LG G3, but they have taken things a step further.

Leave it to the experts to go ahead and do a teardown of the mighty LG G3, while most of us would be scared to take some screws off. The UBREAKIFIX team has gone ahead and taken it all apart, showing us all its components and giving us an idea of how easily repairable it is.

LG G3 specs (just in case you forgot)

  • 5.5-inch display with 2560 x 1440 resolution
  • 2.5GHz Snapdragon 801 CPU
  • 2GB (or 3GB w/ 32GB model) of RAM
  • 16/32 GB of internal storage (microSD support)
  • 13MP/2.1MP cameras
  • 3000 mAh removable battery

What stands out?

As expected from the usual teardown, things don’t look too exciting inside smartphones. We may find the occasional detail worth mentioning, so we should focus on those specific discoveries.

Right off the bat we can see that whopping 3,000 mAh battery, which is removable. This makes for a very pleasant battery swap process – simply pop out the old one and put the new one in. Isn’t it insane that many have to send devices in for “repair” just to have the battery exchanged?


Another upgrade seen in this teardown is an improved motherboard, only housing one small daughterboard. LG seems to have made many changes since the LG G2, giving us a more flexible device that is easily repaired. The G2 had a “controller board split along both sides of the motherboard”.

Also interesting is the fact that this device has a TV antenna, which is very usual in Asian markets. It is very likely we won’t see this part in US versions. As for the motherboard, itself – it houses the following components.


  • (Purple) Broadcom BCM4339 5G WiFi combo chip
  • (Teal) Avago ACPM-7700 power amplifier module
  • (Red) Qualcomm WTR1625L RF transceiver
  • (Green) Qualcomm WFR1620 receive-only companion chip
  • (Orange) SK Hynix 2GB/3GB LPDDR3 RAM layered on the 2.5 GHz quad-core Snapdragon 801 processor.
  • (Yellow) ANX7812 USB SlimPort Tx IC
  • (Blue) Texas Instruments BQ24296 battery charge management and system power path management chip.
  • Toshiba THGBMBG8D4KBAIR 32 GB on-board NAND flash memory on the other side

Is it hard the phone hard to repair?

The teardown proves the LG G3 is quite a success in terms of engineering and repairability. UBREAKIFIX claims the device was very well made, giving it an 8/10. The use of different connectors, instead of flexes, will help with repair time and effort. In addition, the location of the screen connectors makes the device much easier to fix.

    Holy crap I want this phone!!! Awesome specs, removable back and battery, and SD card slot all add up to be easily repaired. Like freaking take my money already!! This is awesome!

    • MasterMuffin

      Are you sure the phone you sure want? :D

      • Jayfeather787

        Yes I am sure the phone I sure want.

    • Jermaine Smit

      But the question is… Are you a spec junkie or are you really looking at how usefull the phone is?

      • Jayfeather787

        What does it matter. It’s a super awesome phone spec wise and in terms of being a phone.

        • Corbin Crutch

          What if I see both?

      • Jesus

        best camera. If not, very, very decent (more than eough for anyone). Biggest and the best screen, on a phone size that is ‘normal’. UI is not bad either. Removable battery, ‘premium feel’, SD card support… What’s missing?

  • Xavier_NYC

    RELEASE THE KRAKEN.. No but seriously make this phone available already….

  • Karl Mose

    “Is it hard the phone hard to repair?”, maybe you should check that :)

    • Dimitar Gospodinov

      I was just about to paste it too…:D

    LG makes their phones easy to repair, especially the most common repair being a cracked digitizer. So easy a child could do it when compared to the HTC One, which was an awesome phone for music but impossible to replace a cracked screen.

    LG has made an awesome phone with the G3 and I impatiently await a battery review. 7hrs of screen on time has been reported, but AA will let us know soon I hope.

    looks like butt hurt fanboys are mad that the G3 poops on their HTC M8 and S5 asking “but is it useful, its just specs” god you guys make me chuckle something good

    • cizzlen

      lol wut. I have the M8 and I’m dumping this bitch for the G3 as soon as it comes out. But I agree, too many fan boys on these sites.

      • Sunny

        I would appreciate your m8 if you don’t need it ^^

        • cizzlen

          Unfortunately I will be trading it in to T-Mo when the G3 becomes available

    LG has impressed us with the G3 which comes in at under £500 but packs amazing features including that Quad HD and a camera with a laser auto focus. The device is surprisingly small considering the 5.5in display and we like the more premium design. It’s another winner from LG.

    For an LG G3, is it possible to cross check
    with SN on the motherboard or SIM connector located there and try to
    match it to the smart phone SN or IMEI code just to know if motherboard has been changed or not taking into account that the phones doesn’t work at all .

    Thanks in advance

  • Eduardo B. Sandoval

    is any way that i can transfer the internal memory to the new mother board? I am interested in saving some files

  • If any G3 owner like me came back to this post after googling how to repair the G3’s motherboard gimme an upvote :) My G3’s motherboard is dead …… :'(
