    • Das LG G4 wird nicht von g-Kräften oder Meerschweinchen betrieben; hier eine Liste der tatsächlichen Antriebskräfte:

    • 5,5" IPS "Quantum" Display mit einer Auflösung von 2560 x 1440 Pixeln (538 ppi)

    • 6-Kern, 1,8 GHz, 64-bit Qualcomm Snapdragon 808 Prozessor

    • 3 GB RAM

    • 32 GB on-board Speicher, mit micro-SD Karte erweiterbar auf bis zu 2TB.

    • 16 MP, f/1.8 Rückkamera mit OIS und Laser-unterstütztem Autofokus sowie eine 8 MP f/2.0 Frontkamera

    • 802.11 a/b/g/n/ac wi-fi, Bluetooth 4.1 BLE und NFC Konnektivität.

    • Android 5.1 Lollipop

    • Hier wird kein Werkzeug benötigt! Das G4 hat eine praktische Einkerbung an der Seite der Rückabdeckung, um sie einfach per Hand abzunehmen.

    • Was die Reparierbarkeit angeht, sieht das schon mal sehr vielversprechend aus.

    • So ein einfacher Zugang durch die Rückabdeckung erwärmt unsere Herzen (netterweise nicht wie sonst unsere iOpener), vor allem wenn man das Handy mit den vielen anderen vergleicht, die oft starken Klebstoff unter der Rückschale haben.

    • Wir brauchen nicht einmal Röntgenstrahlen, um zu sehen, dass dieser Akku vom Nutzer ersetzt werden kann.

    • Aber mit Röntgenbildern macht es trotzdem mehr Spaß!

  3. LG G4 Teardown: passo 3, imagem 1 %32 LG G4 Teardown: passo 3, imagem 2 %32 LG G4 Teardown: passo 3, imagem 3 %32
    • Der 3,85 V Lithium-Ionen Akku verspricht eine Leistung von mindestens 11,2 Wh. Obwohl LGs Marketingteam keine genauen Angaben zur Lebensdauer des Akkus angibt, haben sie uns versichert, dass der 3,000 mAh Akku ewig hält.

    • Das Galaxy S6 ist dem G4 dicht auf den Fersen mit einem 3,85 V, 9,82 Wh Akku.

    • Das iPhone 6 hat einen 3,82 V Akku mit einer Energiewertung von 6,91 Wh verbaut.

    • Trotz der beindruckenden Werte, freuen wir uns am meisten darüber, dass der Akkku so einfach auszuwechseln ist.

    • In letzter Zeit haben wir leider einen beunruhigen Trend beobachtet, nämlich dass Flaggschiff-Smartphones Akkus verbauen, die sehr schwer auszutauschen sind. Sogar Samsung in ihrem neusten Flaggschiff-Smartphone.

    • Es ist sehr erfrischend zu sehen, dass LG scheinbar eine der letzten großen Firmen ist, die sich nicht an dem Krieg gegen auswechselbaren Akkus beteiligen, denn, wie du weißt, sterben Akkus leider irgenwann einmal.

  4. LG G4 Teardown: passo 4, imagem 1 %32 LG G4 Teardown: passo 4, imagem 2 %32
    • Es sieht zwar aus wie ein gewöhnliches Stück Plastik, aber so, liebe Freunde, sieht Freiheit aus! Durch die winzigen Plastiklaschen an der Rückschale kann diese mit Leichtigkeit abgenommen werden. Eine simple Technologie, die uns so in Vergessenheit geraten erschien wie römischer Beton.

    • Doch halt, da ist noch mehr! Wir erspähen ein paar Kontakte, die aus dem Plastik herausgucken.

    • Nach ein paar Röntgenstahlen stellen wir fest, dass es sich um eine getarnte NFC-Antenne handelt, keine drahtlose Ladespule.

    • Falls ihr schon gehofft hattet, ihr könntet das G4 direkt auf die Qi Ladestation legen, müssen wir euch leider enttäuschen. Das G4 unterstützt Qi Laden nur mit einem speziellen Gehäuse.

  5. LG G4 Teardown: passo 5, imagem 1 %32 LG G4 Teardown: passo 5, imagem 2 %32 LG G4 Teardown: passo 5, imagem 3 %32
    • Wir sind bis zum Mittelrahmen gekommen, ohne auch nur unseren Werkzeugkoffer zu öffnen. Das erste was wir nun benötigen, um weiter zu kommen, ist unser Pro Tech Schraubendreher Set, um die gängigen #0 Kreuzschlitzschrauben herauszubekommen.

    • Danach schnappen wir uns ein Opening Pick, um den Mittelrahmen anzuheben und das Herz des G4 freizulegen.

    • Wir werfen einen kurzen Blick auf die Modellnummer —LG-H811— bevor wir es auseinanderreißen weitermachen.

    • Die Leichtigkeit, mit der dieses Smartphone geöffnet wird, sowie die Einfachheit der Komponenten erinnert uns an die gute alte Zeit der einfach reparierbaren Android Smartphones. Das G4 scheint ein Vorzeigemodell für schlanken Luxus und gute Reparierbarkeit zu sein.

  6. LG G4 Teardown: passo 6, imagem 1 %32 LG G4 Teardown: passo 6, imagem 2 %32
    • Die 8MP Selfiecam ist kein Hindernis für unseren Spudger.

    • Am auffälligsten an der kleinen Kamera ist der etwas kontroverse Glättungseffekt, der manchmal nützlich sein kann - wenn du grade keine scharfen Details brauchst.

    • Obwohl es für uns nicht sichtbar ist, hat das G4 anscheinend auch einen ultradünnen 0,1 mm blauen IR-Filter, der Infrarotinterferenzen abblockt, um Fotos einen "natürlicheren" Look zu verpassen.

    • LG versucht seinen Instagramfans auszuhelfen: bessere Fotos und man kann immer noch #nofilter sagen. Zumindest technisch.

  7. LG G4 Teardown: passo 7, imagem 1 %32 LG G4 Teardown: passo 7, imagem 2 %32 LG G4 Teardown: passo 7, imagem 3 %32
    • Wir ziehen das Motherboard aus dem G4 und bekommen eine bessere Sicht auf sein Silizium. Diese Bauteile sind auf dem Motherboard zu finden:

    • Samsung K3QF6F60AM-QGCF 3 GB LPDDR3 RAM

    • Der Hexa-Core, 1.8 GHz Qualcomm Snapdragon 808 SOC liegt direkt unter dem RAM.

    • Toshiba THGBMFG8C4LBAIR 32 GB NAND Flashspeicher

    • Broadcom BCM4339HKUBG 5G WiFi Client

    • Qualcomm PMI8994 Power Management IC

    • IDT P9025A Qi Empfänger für kabelloses Laden.

    • Qualcomm WTR3925 LTE Transceiver

    Thanks for this great document. I was looking into how to fix the WIFI and Bluetooth. My older G4 has problem to turn on WIFI nd bluetooth, I finally get to see the parts oday by using your chart.......but I do not know what I can do......should I try to bake the mother board???

  8. LG G4 Teardown: passo 8, imagem 1 %32
    • Chips auf der Rückseite:

    • Avago ACPM-7717 Multiband Multimode Leistungsverstärker

    • Qualcomm WCD9330 Audio Codec

    • SlimPort ANX7816 Ultra-HD Transmitter

    • Qualcomm PM8994 Power Management IC

    • NXP 47883 NFC Controller

    Is the Qualcomm WCD9330 where the DAC resides?

    Lotus Flower - Responder

  9. LG G4 Teardown: passo 9, imagem 1 %32 LG G4 Teardown: passo 9, imagem 2 %32
    • Zurück im Rest des G4. Wir heben die 16MP Rückkamera heraus, um sie genauer anzuschauen.

    • Die Kamera ist ausgestattet mit einem 1/2.6" Bildsensor, sowie einem Laserautofokus und optischer Bildstabilisation. Der hauptsächliche Fokus der Diskussion ist aber die f/1,8 Blende.

    • LG hat ebenfalls ein paar erweiterte Funktionen hinzugefügt - inklusive Belichtungsausgleich, Bildaufnahme im RAW Format und weitere Optionen - die manuell justiert werden können.

    • Von dieser Seite des G4 aus können wir einen Blick auf den IR Blaster werfen (links neben der Öffnung für das Mikrofon).

    • Bleibt nur zu hoffen, dass das Handy durch die Möglichkeit, es als Fernbedienung zu verwenden, nicht verflucht ist, für immer zwischen den Sofakissen zu verschwinden...

  10. LG G4 Teardown: passo 10, imagem 1 %32 LG G4 Teardown: passo 10, imagem 2 %32 LG G4 Teardown: passo 10, imagem 3 %32
    • Die Komplexität der Rückkamera und ihrer Bildstabilisation ist sogar noch beeindruckender durch die Röntgensicht. Dieser Rahmen! Diese Chips!

    • Die winzige Kamera direkt daneben ist die Frontkamera. Nur eine simple Linse und ein Bildsensor ohne OIS Mechanismus.

    • Von der Seite sieht die Rückkamera ein bisschen aus wie Nessie. Zufall? Vielleicht, vielleicht auch nicht.

  11. LG G4 Teardown: passo 11, imagem 1 %32 LG G4 Teardown: passo 11, imagem 2 %32
    • Wir richten unsere Aufmerksamkeit auf die Kopfhörerbuchse und ziehen sie mit einer Pinzette aus dem Gehäuse.

    • Unsere Teardowningenieure bemerken die coolen Federkontakte der Kopfhörerbuchse, die für leichte Reparatur sorgen.

    • Ein guter Tag, wenn die Kopfhörerbuchse einfacher auszuwechseln ist als die meisten Komponenten deiner Kopfhörer. Äh, earpods.

    • Die Kopfhörerbuchse ist nun völlig frei und ungebunden.

    • Federkontakte sind ein großartiger Weg, Komponenten zu verbinden: Kein Löten, unkompliziert und einfach zu ersetzen.

    • Die dunklen Bereiche auf dem Röntgenbild sind die Metallkontakte, die Signale von der Kopfhörerbuchse zum Mainboard senden, und andersrum. Die grauen Bereiche sind einfach nur das Plastikgehäuse.

  12. LG G4 Teardown: passo 12, imagem 1 %32 LG G4 Teardown: passo 12, imagem 2 %32 LG G4 Teardown: passo 12, imagem 3 %32
    • Ein weiteres Bauteil mit Federkontakten: der Vibrationsmotor.

    • Der Vibrationsmotor scheint ein Knopf-Vibrationsmotor zu sein. Die zwei länglichen "O" Formen sind Drahtspulen, das dunkle ambossförmige Teil ist ein Gewicht, das sich dreht, um den Motor zum vibrieren zu bringen.

    • Von der Seite bekommen die Federkontakte mehr Volumen, und man kann die einzelnen Fasern der Drahtspulen erkennen. Cool.

  13. LG G4 Teardown: passo 13, imagem 1 %32 LG G4 Teardown: passo 13, imagem 2 %32 LG G4 Teardown: passo 13, imagem 3 %32
    • Das LG G4 bekommt von uns 8 von 10 Punkten (10 ist die beste Reparierbarkeit).

    • Rückschale und Akku können ohne Werkzeug entfernt werden.

    • Viele Komponenten sind modular und können einzeln ersetzt werden.

    • Gängige Kreuzschlitzschrauben #0 machen es einfach, einen passenden Schraubendreher zu finden.

    • Verschmolzene Displayeinheit—Glas und LCD müssen gemeinsam ersetzt werden, falls eins von beiden kaputt geht.

    • Und zu guter Letzt möchten wir unseren Freunden von Creative Electron für ihre Ausrüstung und Expertise danken!

These X-Ray tear downs are really interesting. Hope to see more in the future!

Robert - Responder

It must kill LG to have to use Samsung RAM chips.

Shawn Latin - Responder

Corporations do not have emotions.

Almost everybody buys from anybody. Samsung sells parts to Apple, etc, etc.

It's all about maximising profit. Do that and nobody cares where the parts come from (unless your corporation can do it cheaper itself.)

Mike Reid -

Awesome! I loved this X-Ray feature.

Marcel Cintra - Responder

Looks like the external speaker is also connected with spring contacts! I've had notoriously bad luck with external speakers, so this is awesome!

David S - Responder

Anyone knows where I can purchase the rear camera module? My daughter shattered the glass.

Thanks in advance.

TheDoctor Who - Responder

Any info on sensor chips?

hunter - Responder

Hi. The plastic trim around the screen is all attached is it? There's no way of replacing it without replacing the whole screen?

Paul Garner - Responder

you could probably use a heat gun to seperate the glass from the from i know you buy just the frame on amazon

aaron brogan -

Excellent guide, The place I work will not allow cameras on the work site, will the phone still work with the cameras removed completely?

taylorraymond - Responder

Dude...Just cover the cameras up and call it a day (And disable the camera app)

niccotaglia -

There are a LOT of reports of the wireless charging breaking after several weeks to a month of use. As in, the Qi wireless charging ability completely dies. This is unfortunate!

On their website IDT is no recommending the 9025A and has a newer model, the 9025AC. Are these 2 facts related? Will LG upgrade newer ones to this chip?

WL1 - Responder

Hi. My unit was manufactured in may 2015 (as per the serial number found on the retail box) and found out that units manufactured before sept. 2015 has a design flaw. Mine was purchased in june 2015. started to boot loop in oct 25 2015. Returned it to LG. their assessment was for mother board replacement.

How can I change the bottom microphone? It stopped working/something might be clogged in it, and it doesn't appear to be in this teardown. Please help!

Emmet Spiegel - Responder

Did you find any sulotion? I have the problem now. Thank you if you help me.

houman -

I'm also having this issue after about a year of use. Is it possible to access the port without having to take off the motherboard?

Myles O'Connor -

Hi all. My G4 H815 was manufactured in June 2015. Mine was purchased on 24 July 2015. started to boot loop on 19 November 2015. Returned it to LG the next morning and just got my motherboard replaced and received a November 2015 unit today. The technician does not know the problem of the unit when asked.

Walao Eh - Responder

did you get the motherboard replaced ? and is it working fine with new motherboard now

Ashwani Bhat -

My husband dropped his brand new LG G4 in salt water. The motherboard burned. Can it be replaced?

Hendrik van Zyl - Responder

My LG G4 is going through a "Bootloop" I wanted to know if the internal memory could be removed to retrieve the inner contents. That or just fixing the Bootloop seeing how LG admits to this being a defect in most device's in the components of the device.

Edgar - Responder

how can i boost antenna main signal strength. phone showes no signal and iphone has 4 bars

Toby Andrus -

Same thing happen to my unit, bought in July 2015. Started boot loop and died off subsequently last week. Return to LG and had motherboard replaced.

Ralph K - Responder

is your g4 working fine with the new motherboard or has it faced the bootloop issue again

Ashwani Bhat -

LG knows of the boot loop issue. It's seems to be a batch where the processor becomes loose from the motherboard. Heat gun and sticking freezer are quick very short term solutions. LG will replace phone or board no real questions asked.

Jon Hartsock -

Wait. H811? I have an unlocked G4 and it says H815

niccotaglia - Responder

Any ideas on how to fix the bootloop issue?

aliceleemail - Responder

It can't be fixed as it's not a software issue, it's a hardware issue. The only way to fix it is have LG replace it unfortunately :(

Craig -

Can be fixed short term by puttin freezer

Jon Hartsock -

Is it possible to remove the Toshiba THGBMFG8C4LBAIR 32 GB Flash memory and place it into another G4?

Jon - Responder

Did you get a reply to this? I'd like to know, too.

matthewtreed -

Of course, I've done it yesterday

Александр Иванов -

Where is the Bluetooth module or antenna located?

Olaf Hoyer - Responder

I have very bad 3G network connection the strength sucks. where is the antenna located?

Thanks for reply

psychokuh - Responder

I lucked out buying the G4 last year for my wife. The screen, camera are superb. Now I'm glad the repairability is strong. Now this is a primary deciding factor in buying a phone. I don't think I'll be buying a new phone for a while, even this G4 was second hand, like new.

Jack - Responder

The NFC antenna can it be upgraded or possibly can I make one

Ace - Responder

Sol69h Sol - Responder

hi needs help from where can I buy Samsung K3QF6F60AM-QGCF 3 GB LPDDR3 RAM

Omar - Responder

Why do you think about RAM. RAM crashes in the phones very rarely, DO NOT THINK THAT BOOTLOOP WAS CAUSED BY RAM OR CPU. THIS IS VERY BAD NAND SOLDERING. REBALL IT AND ALL WILL BE NICE.

Александр Иванов -

can somebody learned in the ways of motherboards tell me if there's any possible way to pull off pictures, music, notes, etc. after the G4 goes into its bootloop? I have a lot of priceless files and data on this phone I would probably sell my soul for. As far as I know, it's irretrievable. Can someone confirm or deny this?

To anyone considering this phone, stop. This is my second LG G4 that died due to motherboard manufacturing issues. They aren't isolated instances. Most users have had this issue within 6 mos. to 1 yr. of purchasing. Interesting how the phone dies right around the end of its 1-Year Warranty.

I have no interest in having this phone replaced by LG or repaired since I already ordered a new phone. I just want to extract the files. There has to be some way to do this. I find it hard to believe that in December 2016 that this can't be done. The only reason I haven't gone Office Space on this otherwise useless phone is because I still have hope I can retrieve my lost files.

LGMakesMeSad - Responder

Of course, but only if you have equipment. Only some of repairman can do it.

Александр Иванов -

Put it in the freezer in a Ziploc bag. Wait about an hour. Should boot normal. But will give u a short window to get files off. Once chip starts heat up, jumps into boot loop again. I had good luck sandwiching phone between 2 big ice packs and using my laptop with usb. micro cable download all files needed.

Jon Hartsock -

Desolder the eMMC chip and insert it into the correct eMMC chip reader. Unless the data is encrypted, you can access even the things you wouldn’t access through your phone’s file manager. Then you can even change the bootloader, root the phone, download everything eg. documents, load or store backup, perform recovery of your deleted files.. When you’re done, reball the chip back on the motherboard and your phone may work fine if you do everything correctly.

patrikstaron -

Does anybody know where the GPS Antenna/contacts are? My GPS stopped having reception a while ago, would like to see if there is a fix possible.

hans - Responder

I'm aware the g4 has two external LDI stickers. One in the battery compartment and one on the battery itself. But does it have internal ldi stickers?

Nunyally Li - Responder

maurice1975 - Responder

Anyone know which IC deals with the touchscreen? I have a new frontpanel and digitizer and LCD, all were working before the Bootloop/dead phone issue. I got the phone working again with a heat gun to only the mother board. but no touch screen. Roger - 1/28/17

Roger - Responder

I need the replacement of the front receiver for this cell phone. Do you have it available? Thanks!!

RICARDO - Responder

Hey, after a waterdamage and a bath in Isopropanolalcohol to save it, my LG G4 reacts normally. Touch, Calls, Cam etc. But the screen stays very very dark. You almost cant`t make out anything. What can it be?

Chattering H - Responder

On the mainboard:

What function does the mainboard smaller part (under NFC chip) have?

I have the mainboard with that smaller thin lateral side (antenna I think) broken but it works apparently normal: bluetooth, wi-fi signal, carrier signal, etc

I love this… It was so informative… Keep up the great work!

Jesus Child - Responder

The seal in front of the camera (removed in step 5) I took off thinking it was just for decoration, but little did I know it also kept debris from entering the camera mechanism! Now, my camera sometimes refuses to boot, but if you take a needle and go around it’s perimeter and clear away dust, it starts to work. In addition, and the reason I came here, is that I now have a more permanent spec of dust behind the lens itself, so I will have to disassemble the camera or get a new one…
