  • Much like in the Galaxy Nexus, we find a user serviceable battery in the Samsung Galaxy S III.

  • The 3.8 V, 2100 mAh battery incorporates the antenna for the Near Field Communications (NFC) module used in "S Beam".

  • Internals time. The spudger takes care of the first two plastic assemblies.

  • The first piece out is the rear plastic frame that protects the motherboard and houses a single liquid indicator sticker.

    • Should your Galaxy S III ever take a swim, be sure to stick it in one of iFixit's Thirsty Bags.

  • Removal of the frame grants us access to an easily replaceable speaker assembly.

  • The big question now is what we should remove first. So many components in such a small volume!

Image 1/1: This will greatly increase the amount of money one has to spend when replacing the glass, should one be unfortunate enough to break it.
  • The glass is fused to the display, and the display to the Galaxy S III's frame.

Get a glass protector...got one from Radio Shack and seems to work just fine. I have dropped my phone a few times and nothing has happened...also have one of those rubber cases that wrap around it....seems to also work as advertise...I know hard to believe!!

when replacing the front glass on the s3 the touchscreen controls on the bottom if one was to accidentally cut the cable to one do you have to buy a new digitizer

Image 1/2: Samsung Galaxy SIII Repairability Score: '''8 out of 10''' (10 is easiest to repair) Image 2/2: The battery can be replaced without any tools.
  • Update: This teardown was conducted solely via Interweb, requiring us to defer judgment on a repairability score. Now that we've worked on it ourselves, we can assign it a fair score:

  • Samsung Galaxy SIII Repairability Score: 8 out of 10 (10 is easiest to repair)

  • The battery can be replaced without any tools.

  • Very easy to open and access internal components.

  • There are only 12 screws in the entire device, all standard Phillips #0 (no proprietary or security sizes).

  • Smaller components (antennas, vibrator, light sensor) are modular and can be replaced individually, but are adhered to the front panel.

  • The glass is fused to both the display and the display frame, increasing repair costs.

  • You'll have to go through the entire phone in order to replace the front panel, since everything is built into the back of it.

The nob that I touch to turn phone on and off not the switch it self. Mi nob dropped out. Switch is good just need the nob

Hi Guys, the PMB5712 tranceiver is from Intel, not from Infineon.

Herbert - Reply

can you guys do a teardown of the Sprint one so we can know if the LTE SIM card is soldered in or simply covered by the plastic?

Any one know what type of connector they use for the two antenna test ports (bottom right). They aren't MMCX but I'm not sure what they are.

why is there STILL no repair score?

What's the tiny silver chip right beside the power button? I melted a corner of it with my soldering iron when I was replacing the power button and now my GPS doesn't work.

This post is really great! Now I know how to to my stuff. Thanks for posting this informative article. As for my part, my battery has issues and that's why I bought new a new battery . If in any case this one will still have issues then maybe my phone is defective itself. But I do appreciated this post - it's a great help!

I was wondering if it is possible to replace the charger plug on a galaxy s3. Mine won't charge for more than 3 seconds and I thing it has something to do with the plug. I have pictures on it that I really want to keep, but I can't get it to charge.

We have a full set of repair guides for the S III, just check out the device page, here's the motherboard replacement guide that shows you how to remove the component the USB port is mounted to. You can either resolder the port, if it's not damaged, or replace the motherboard entirely.

Hi, im having troubles with my phone after of a LCD replacement, the phone sometimes work and sometimes don't, i fix this problem removing the plastic mid-frame and putting it again. So i think the problem is in the contacts between the motherboard and the plastic mid-frame..
