  1. With the newest addition to the Galaxy S line, Samsung has decided to ditch the roman numerals. Let's take a look into the specs of the Galaxy S4 (not SIV):
    • With the newest addition to the Galaxy S line, Samsung has decided to ditch the roman numerals. Let's take a look into the specs of the Galaxy S4 (not SIV):

      • 5" display with a resolution of 1920 x 1080 at 441 ppi (just shy of the HTC One's 468 ppi)

      • 16, 32, or 64 GB of internal storage, expandable with up to 64 GB of external microSDXC storage

      • 2 GB RAM

      • 13 MP rear-facing camera and 2 MP front-facing camera

  2. Straight out of the box, we are already sighing with relief…it's a removable battery!
    • Straight out of the box, we are already sighing with relief…it's a removable battery!

    • This trend makes us oh-so-happy! Samsung is doing the right thing for their customers and the environment.

    • Not only is the battery removable, it even comes removed! The rear panel rests upside-down on the device, so we don't even have to release any clips to open it up.

    • Resting in the battery cavity is our micro-SIM card delivery system: an advanced piece of plastic from whence the micro-SIM card came. It provides super-important numbers for the life of your micro-SIM card, all in one easy-to-lose thin piece of plastic!

    • We know it may be comparing Apples to Oranges, but we are tempted to see how Samsung's S4 differs from Apple's latest: the iPhone 5.

      • The S4 rocks a 5" full HD Super AMOLED display, compared to the iPhone 5's Retina display, which is a 4" IPS LCD.

      • The Galaxy S4 is considerably larger than the iPhone 5, clocking in at 5.38" x 2.71" x .31" and weighing 4.6 ounces. The iPhone 5, for comparison, measures 4.87" x 2.69" x 0.30" and weighs 3.95 ounces.

      • Both phones are available with 16, 32, or 64 GB of internal storage, but the S4 also offers up to 64 GB of microSDXC storage.

    • One of the acclaimed new features of the S4 is Smart Pause, which automatically pauses video playback when the user looks away from the screen.

    • Like all good "Life Companions," the S4 wants the attention it deserves—when it's talking to you, you'd better be looking!

    • It wasn't long after we started playing with Smart Pause for ourselves that we knew we'd have to find a way to trick it...

    • After a quick test drive, it's time to take the battery back out and get to work. New software features are cool, but we're much more interested in getting down to what powers them.

    • The back panel is as easy to remove as they come—a fingernail in the groove is all you need to get this phone open.

    Step 5 - What's this black adhesive tape on the black panel, just above the QR code?

    • You put the battery in, you pull the battery out, you put the battery in…and you shake it all about!

    • The lithium-ion battery is rated at 3.8 V and 2600 mAh (9.88 Wh). Its advertised useful life allows for up to 7 hours of talk time, and up to 12.5 days of standby.

    • With no time to waste, we slide the pre-installed micro-SIM card out of the way.

    • Just like in the previous iteration, a few screws hold the plastic midframe in place.

      • We were hoping that we'd find a magnesium midframe like in the S4's great-grandparent. Alas, it looks like we won't be playing with fire in this Galaxy.

    Aggiungi Commento

    • After removing the screws, there are still a few clips securing the plastic midframe of the S4 in place.

    • They are easily released with the help of a plastic opening tool, a tool that is truly out of this world. Our first view of the circuit board is rather familiar.

    • Remaining in the midframe are the springy volume and power buttons, amply-sized speaker, and a liquid damage indicator.

    • With little effort, we remove the speaker assembly from the midframe.

    • Unlike the dual front-facing speakers in the HTC One, the S4 keeps its primary speaker down at the bottom of the back of the phone.

      • This is the prime location for a speaker if your ears are attached to your hand while holding the device.

    • While the sound quality may not be hot and fresh out the kitchen, the speaker does pack quite the punch and can pump out your favorite mashups loud and clear.

    Who could provide me some details/technical details about the audio components of the samsung S4 like: microphones, loudspeaker, ear-speaker, earphone jack.

    I guess they are all Samsung OEM products, but I'm not very sure.

    I would really appreciate if someone could give me some hints or information about.

    Thank you in advance!

    • With the midframe off, several connectors and a single screw are all that hold the motherboard in place. Our two favorite tools are all we need to get it out.

    • Just how great does Samsung think their phone is? If you couldn't tell from their unveiling show, an internal stamp informs us this device is straightup 1337.

    Aggiungi Commento

    • Before we can examine the motherboard, we need to pull off the rear-facing camera.

      • The gravitational attraction between the motherboard and the camera as we pull them apart is roughly 0.0000000000098 Newtons, so this task is easily accomplished by our team of strapping young technical writers.

    • Very much unlike HTC's recent disregard for the megapixel race, Samsung has opted for a rear-facing camera boasting 13 megapixels. It also sports the now-standard LED flash, a back-illuminated sensor, and the ability to record full 1080p HD video at 30 fps.

    Any idea which imaging IC sensor they are using? The lens seeltion? Any chance to see a tear down of this camera? How about a pinout of the connector? And connector type?

    • Resting atop the motherboard is the SIM/microSDXC board.

    • On one hand, the modular design of this component makes it possible to replace if you happen to jam something into one of the two slots—although you will need to replace both at once.

    • On the other hand, the adhesive securing it to the motherboard makes it something you wouldn't replace unless you had to.

    What are the two metal pins used for on this piece? I see only the stock wireless charging cover uses them but everything aftermarket only uses the two on the left (On the main motherboard)

    Parker Reed - Replica

    It is a pity, you couldn’t get an answer.I’m sure you are not the only one who would like to know.

    straydog1984 - Replica

    It is sticky and remove it together with the metal shield underneath seems easier than removing the sim module alone.

    • Qualcomm MDM9215M 4G GSM/UMTS/LTE modem

    • Qualcomm PM8917 power management

    • ARM Holdings MBG965H (right)

    • Samsung K3QF2F200E 2 GB LPDDR3 RAM (we suspect the Snapdragon 600 APQ8064T 1.9 GHz Quad-Core CPU lurks below)

    • Toshiba THGBM5G7A4JBA4W 16 GB eMMC (eMMC integrates a NAND flash memory and a controller chip in a single package)

    • Qualcomm WCD9310 audio codec

    • Broadcom BCM4335 Single-Chip 5G Wi-Fi MAC/Baseband/Radio (thanks to a tip from a user, and our friends at chipworks, we believe there's something underneath this chip)

    • Bosch Sensortec BMP180 barometric pressure sensor (left) - Samsung outputs the height in meters as second parameter.


    You are tearing down the LTE version. Chipworks tore down the HSPA version. WiFi in HSPA version is Broadcom. It might be different in LTE version as there are rumors it might be Qualcomm/Atheros. Can you please check?

    Sam - Replica

    What about Qualcomm PM8917

    Ivalo - Replica

    The VZW version appears to use a Qualcomm MDM9615M instead of the 9215 radio chip.

    Is it possible to pull the memory and place into another motherboard? We have a fried mother board and need the data stored in the memory.

    awatts0 - Replica

    ditto: I’m wondering the same thing. I have 2 old S4 phones. One powers on and one does not power on. I wonder if it’s possible to transplant my memory from phone A and put into phone B so I can recover the data?

    • Reflowing the Broadcom module off the motherboard reveals a stow-away located beneath it: a Skyworks SKY85303-11 2.4 GHz, 256 QAM WLAN/Bluetooth® Front-End Module.

    • Moving over to the other side of the Galaxy:

      • Skyworks 77619 power amplifier module for quad-band GSM/EDGE

      • Qualcomm WTR1605L seven-band 4G LTE chip (same one found in the Nexus 4)

      • SWA GNF09

      • Broadcom 20794S1A standalone NFC chip

      • Maxim MAX77803 microcontroller

      • Silicon Image 8240BO MHL 2.0 transmitter

      • Qualcomm PM8821 power management IC

    Beautiful Picture. Thanks Fixit did a good job and contribute to reduce eWaste.

    • With the motherboard out of the way, we can focus our efforts on removing components attached to the front of the device.

    • The first component out is the standard 3.5 mm headphone jack. A swift flick of our trusty spudger, and poof! It's out!

    • Samsung left no useful space un-adorned with extra components—the headphone jack is home to the status LED and the first of a pair of IR sensors.

    • Poke poke, flick flick, tweeeeeze!

    • With all of the easily-removed components out of the way, we get to work peeling up the remaining, slightly-adhered parts filling the Galaxy S4's display assembly.

    • First out is a multi-purpose component that connects the earpiece speaker, IR blaster, and a sensor array hosting the ambient light sensor and a second IR sensor.

      • The placement of the two IR sensors on either side of the earpiece speaker explains how Samsung's new Air View/Air Gesture feature operates. By comparing IR light reflected from your hand into each of the sensors, the phone can track sideways motion as you gesture without touching the screen.

    • The next victim of our anti-adhesive prying campaign is the vibrator motor.

    • The S4 features a linear oscillator vibration motor, similar to those found in its Android brethren, the Nexus 4 and Galaxy Nexus.

    • This particular motor is labeled 53329 34AVCV.

    Aggiungi Commento

    • The daughterboard is home to the full-featured micro USB port. With MHL and USB OTG support, users can use this port for HDMI output and USB peripherals in addition to charging and transferring data.

    • Removing the daughterboard from the device, we get a view of some of its secrets.

      • Sensirion SHTC1 humidity and temperature sensor

      • RFMD RF1119 antenna controller

      • S1029 6914 (this one appears to be a voice microphone)

    in the usb ports, it has enough pins to be used as usb 3.0 also

    I have replaced the digitizer screen(digitizer+glass) on my Galaxy S4 and the menu and back buttons stopped working. In the old screen it worcked ok, i installed the old screen back and in did not worcked too!!!! Any help?

    bazooka - Replica

    Is there a wire underneath the USB port because I just took mine apart and I see a red wire attached. What does that mean? There is a mandatory white wire on the opposite side. Please help!

    Damian Garza - Replica

    The microphone itself is in the speaker module. What you think is a microphone is indeed a crystal oscillator.

    Eric Castro - Replica

    • The front panel assembly is the final piece to the puzzle.

    • Unfortunately, the display and front glass are fused, with a layer of optical adhesive. The glass is then adhered to the plastic display frame, making a single assembly. Not a big surprise.

    • Getting a look at the second liquid damage indicator on the back of the screen, and—whoa, what's this hiding down there?

      • Looks like we've spotted the touchscreen controller, a Synaptics S5000B.

      • This chip is responsible for the S4's super-sensitive touchscreen, which even works with gloves.

    Aggiungi Commento

    • Samsung Galaxy S4 Repairability Score: 8 out of 10 (10 is easiest to repair)

      • The battery can be replaced in seconds, without any tools.

      • Very easy to open and access internal components.

      • There are only 11 screws in the entire device, all standard Phillips #0 (no proprietary or security sizes).

      • Most of the smaller components are modular and can be replaced individually, but several of them are adhered in place, increasing replacement difficulty.

      • 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.

John Santos - Replica

Hi there.did you find out?

guyphone -

Its amazing how much wasted (blank) space there is on the logicboard and "a fingernail in the groove is all you need to get this phone open" literally means it will start falling apart as the phone wears.

Why do people keep comparing junk like this to the iPhone? They are nothing alike. The iPhone is a premium product designed by engineers. The S4 is a low-cost product designed in Korea by kids ("leet"). Seriously, the CPU uses the RAM chip as a heatsink......

aww u mad because s4 is a superior phone thats twice as fast as the iphone 5 and has a superior screen ? :( oh and dosnt scratch just because u pout it down on a table like the iphone :)

Hi, it wasn't really mentioned in the guide, but I was wondering if you could tell me why the wireless charging prongs changed from the S3 to the S4. Particularly why they changed it from 2 prongs on the S3 to 4 prongs on the S4. Thanks!

Daniel Devore - Replica

The prongs on the left (screen down) are for wireless charging. The ones on the right are for a supplemental NFC antenna. Which should solve the problems seen in the S3 with wireless charging and NFC
