Hi everyone, I bought an LG G3 Korean version (F400S) unlocked recently. It is a good phone but I am experiencing three annoying issues (out of the box) with the phone and they are:
1. NO sound at all from the back loudspeaker. The volume is set to maximum, there is no sound from music, video, notifications, touch sound effects, or even ringtone! Surprisingly, when I connect my earphones, there is sound in my earphone, when I remove the earphone, absolutely NO SOUND from the loudspeaker. The sound from ear speaker (the one used to make call) works. I have tested the ringtone in the Hidden Menu, when the ringtone is being played, there is no sound at all.
2. The LG G3 charges well when connected with the charger and when connected with my laptop as well. However, whenever I connect the LG G3 to my laptop, it only charges, it is NOT RECOGNIZED by my laptop. I have the LG Mobile driver installed (downloaded from the LG website (Korea website)), the LG PC Suite installed, the LG Mobile Phone Support Tool installed. Whatever I do, changes the USB cable/ USB port, try in different windows version (Windows 7, 8.1 and 10), USB debugging on and off, reinstall driver, reinstall driver from the option in LG PC Suite, restart the PC several times, NOTHING happens. It is not recognized at all in my laptop. ALSO I cannot see any thing related to LG driver in the Device Manager.
3. USB OTG does not work. I have tried with a working OTG cable to connect a pendrive in my LG G3, it is not recognized, even in the File Explorer of the phone. The cable and pendrive is however detected in my other android device.
The Android version of my LG G3 is Android 4.4.2 (I have received only one update for improving Google experience (about 10 MB).
The Kernel version is 3.4.0
The build number is KVT49L.F400S11a
Software version is F400S11a
Please help me, I have googled for the problems, searched in Youtube as well but no solutions. The phone was bought online, it is original but I have no warranty and even if i need to repair, I will have to send it back to China, which will be money and time consuming. Please help me.

Thanks for the reply, I tried your suggestion, but it did not work. Again, when I tried to connect the LG G3 to the PC so as to flash with the KDZ, it says on the taskbar: 'The last USB device you connected to this computer malfunctioned, and Windows does not recognize it'. In the Device Manager, I get USB Device Not Recognized (Error Code 43), Unknown USB device (Device Descriptor Request Failed) Error Code 43. I googled this issue as well no success, I reinstalled the LG Drivers, rebooted my PC, again NO LG DRIVERS in the Device Manager, and whenever I connect the LG G3 I get the same message I mentioned above. Hence, I cannot upgrade to the v20F version as I cannot connect the device to my PC.
UPDATE: I cannot put the device in download mode for flashing. I hold the volume up button while connecting the cable to the USB 2.0 port. The LG logo appears on the phone and it just charges. Also, I have tried to remove everything related to the drivers and reinstall, now I do not have the Error Code 43, BUT still the phone is not recognized.

Pull the battery
Only press the volume up button while connecting the cable to the USB port.
Let me know if that works. It sounds like your pressing the power button first, pressing volume up and then plugging the usb cable in
If it doesnt theres also the adb method as well that i can tell you after

I tried it but I only get a picture of a battery with a USB cable connected and a yellow triangle with an question mark. No download mode, and it is not detected by my PC. Please give me further suggestions. I am continuously searching how to solve these issues.

First update your drivers on your computer. If that won't work try different ports. USB 2.0 or 3.0 can make a huge difference. Your speaker is probably dead. And i don't have any experience with USB OTG so I can't help you with that

Already tried that with the '15-sec ADB' something like that + with Android studio, I have searched on youtube and google how to do it, but nothing happen when I enter the command, it just says that device not found. Whenever I connect a pendrive or my other phones to my PC, I can see in device manager, it refreshes and the driver for that particular device appears. BUT there is NO refresh nor any driver appearing when connecting the LG G3. Today I tried it with my friend's USB cable (he has the LG G3 (D855), it does not detect as well in his PC but his phone is detected in his PC. I really do not know what is the matter :crying:

Thank you for your reply, I have already tried all of these, nothing is working.
Did you figure out how to get your phone recognized by the computer? I am facing the very same issue and I'm feeling hopeless

No, i am still having the same issue. I think with an update it will be okay (but I have not received any update till now! I am stuck with Kitkat 4.4.2). If it is a hardware problem I will have to return it or replace the USB port or motherboard.

Oh, OK thanks. I'm still reading forums in search for a definite solution.
Good luck!
Anyone else experiencing this? I just got the latest Windows 10 update, the fairly large one, and all of a sudden now the phone won't connect to LG Bridge. It connects to the PC just fine and charges but it will have nothing to do with the app. I even revoked USB permissions, switched to PTP, reinstalled LG Bridge, etc... no help.
Anyone else seeing this or know how to fix it?
EDIT: Well, to make matters worse I tried the "install pc drivers" thing and now the G4 won't even enter MTP mode. It doesn't recognize the USB connection at all.
Second EDIT: Got it fixed. Purged all drivers from my computer and reinstalled them. All good. ignore this thread.
what you mean by purge all drivers? what drivers, where? I'm having the same issue with bridge and windoze 10
Windows 10 here also and cannot get LG Bridge to see my VS986 either - it tries to connect when I switch to MTP mode, but then gives up.
ADB and Verizon Software User Assistant both work fine ......... not sure how to debug this issue.
Hello,
I just got myself a brand new LG G4 H815 and it is running Marshmallow. I want to upgrade to Nougat so I installed LG Bridge on my windows 10 PC, connected my phone with original USB cable but I get message "no mobile device connected". PC recognizes my phone and I can transfer files from and to the PC. I have LG universal mobile drivers installed and the phone is in MTP mode. Weirdly, once I switch it into charging mode, LG Bridge recognizes it but won't allow me to upgrade it since it must be in MTP mode. Can someone tell me a solution to this problem or tell me if I can update my phone in some other way? LG PC suite tells me that there's some sort of Verizon app built into my phone which will do it, but I cant find it anywhere.
This is a common problem. It is some sort if glitch with windows 10
In hardware devices window are u sure the driver doesn't appear as question mark after u connect?
Remove to device driver and let windows reinstall it automaticly when you restart windows
Try again

Yes, I've done it, since I had some issues with other device's drivers on win 10. It didn't help. I'll try on Win 7.
