LG G5: Phone keeps vibrating repeatedly when plugged in. (LG G5)

Sat, 28 Jan 2023 12:31:20 -0700

I recently purchased a phone lot off of eBay just for fun, and I wanted to test it for myself. When I plug it in (with a USB-C cable), it repeatedly vibrates. The vibration patterns change whenever I unplug it and plug it back in for some reason. Is there any explanation for this behavior?

Clarification Edit: When I plug in the phone, the LCD’s backlight should light up displaying the charging symbol, but it doesn’t appear to do that. Instead, the phone vibrates at random intervals. However, when I hold down the power button, the vibrating stops.

LG G5: Why my wifi and bluetooth do not turn on?

Mon, 02 Mar 2020 07:29:51 -0700

Hi,

I bought my new phone and started over heating using wifi and charging the phone. I was using the original charging device. After a while the wifi and the bluetooth won't turn on. I factory reseted the device and have it up to date. And still both wont turn on. Is there a repair for the antenna? Is a hardware issue o a software issue?? Where is the antenna located?

LG G5: How do I turn the knockon feature back on?

Fri, 20 Sep 2019 14:10:07 -0700

Phone model: LG-H850
Hardware version: Rev 1.0
Android version: 8.0.0
Build number: OPR1.170623.032
Software version: V30f-EUR-XX

For those of you who don’t know - LG phones come with a feature called knock on, which allows you to double-tap on the screen to turn the screen off, and double tap again to turn it back on. I’ve always been an avid user of this feature as the power button is situated on the back of the phone, so it’s a convenient feature for when the phone is flat on a surface.

Some time ago, the feature stopped working entirely. I can’t pinpoint an exact moment or update when this happened. Since I’ve noticed the feature being disabled, I’ve tried the following things:

Checked for software updates for both apps and android. None are available.
Uninstalled all recently installed apps.
Tested the touch screen to make sure it wasn’t just an issue with me tapping a broken part. Touch screen works perfectly.
Tested the proximity sensor to see if it was an issue with that. Proximity sensor is working perfectly.
Installed various “hidden setting” apps to access the knock on feature. Unfortunately the knock on feature is never available in the list, which is strange. It’s almost like the entire feature vanished from my phone overnight.
Installed different launchers as some youtube videos recommended this, to no avail.
I have not yet done a factory reset, and would like to avoid this if at all possible, but if someone has reason to believe this will fix the issue at hand, please let me know.

Could anyone recommend how to fix this issue, regardless of whether it’s a software or hardware fix? I’m totally comfortable with taking the phone apart if need be, but if I can solve it with a settings tweak that would of course be preferable.

Thank you in advance!

LG G5: Replace LG G5 SE (H840) screen assebly with one for LG G5 (H850)

Fri, 06 Sep 2019 08:22:01 -0700

Hello everyone!

So my sister has been using her phone (LG G5 SE) with cracked glass for some time now. Since I would be able to fix that pretty easily I wondered where I could get a replacement display assembly. Parts specifically for the G5 SE seem to be more expensive and only available from dealers in other countries.

Some online dealers claim that their part is compatible with both.

Does anybody have experience in that regard? Can I replace the G5 SE screen with one for the regular LG G5?

Thanks in advance!

LG G5: LG G5 Charges but won't turn on

Fri, 30 Aug 2019 02:12:52 -0700

if the battery runs zero, upon plugging, battery shows 0% on screen but indicator on top of the phone blinks then turns off. This is the only time the screen turns on to show 0% and charging, when the screen sleeps, the battery continues to charge while plugged but won’t turn on.

after an hour of charging, the phone won’t turn on, the unit just vibrates once after pressing power button, and nothing else can be done. I have to remove battery to try again but the same thing happens after pressing power button.

tried to enter bootloader mode or download mode with vol down + power button, but nothing happens to the phone. screen remains blank. it doesn’t vibrate as well.

any help to pinpoint the problem is appreciated. I have tried changing with a new charging module and new battery but phone remains the same.

LG G5: I'm at loss. No GSM signal.

Thu, 18 Jul 2019 04:37:17 -0700

First of all - hello, it’s my first question here.

I have a problem with my G5 - no signal reception at all, in settings/phone info/network it shows 0dbm 0asu. Before it worked great, but the problem started after replacing fingerprint scanner, screen and USB port in the bottom module.

Since I know the GSM antenna is in the bottom module you attach the battery to, to troubleshoot the problem I’m using the CamPlus module which I know for a fact has working antenna.

Next thing the Internet told me, that some people break off a small tab on PCB that goes into the module, and that’s causing issues with reception. But as seen on provided pictures - it’s in one piece and looks ok…

I have also tried different back (bought used) to no avail. I’m providing some pictures, so maybe someone will spot a problem I couldn’t?

LG G5: Low earspeaker volume on LG G5

Wed, 26 Jun 2019 08:12:20 -0700

about 2 weeks ago my ear speaker volume went really quiet even though the volume was cranked way up. Tried cleaning the mesh, tried everything I can find on the internet to test and did discover through a hidden test menu that it shows the volume at 4 and max is 7… But there is no explanation on how to change it. I was able to make the volume a little louder when dialing my voicemail but the setting doesn’t stay loud. Physically the volume rocker works and has no issues going up or down on all other volume settings.

I almost threw my phone on the ground a few times out of frustration…

Help!

LG G5: LG G5 H860 and H850 motherboard replacement

Wed, 27 Mar 2019 11:10:32 -0700

My LG G5 H860 is broken and I need to replace the motherboard.

Anyway, I was wondering to buy the H850 motherboard for 3 reasons:

is much cheaper
is easy to unlock the bootloader (the H860 still seems unlockable)
they seems to share the very same specs, except for the dual sim

availability.

Does anybody can confirm it is possible to do that?

Is there any difference I’m not considering?

Thank you,

Jacopo

LG G5: Is the LCD/DIgitizer the same for all G5 models? All Frames the same?

Mon, 04 Feb 2019 18:43:44 -0700

Hi:

From what I am finding it seems all LG G5 LCD/Digitizer units (No Frame) are interchangeable between the models (H820 H830 H850 LS992 US992 VS987, etc…), is this true? And, it seems there are differences (per part listing descriptions) in the screen FRAMES that Prevents all the models from being interchangeable. Is this true, and if so are there any work-arounds or do I just have to get the exact frame for a particular model… or always use the existing frame and do the extra repair work?

Thanks! Tom

LG G5: LG G5 Display Problem

Thu, 17 Jan 2019 22:24:07 -0700

can you help me fix this? what hardware is causing this glitch? and also the screen is black and the glitch is the only a thing that shows up on my screen

Here’s a Screenshot:

LG G5: Trying to assess extent of screen repair/replacement

Tue, 15 Jan 2019 20:28:39 -0700

Screen does not respond to any buttons, reset attempts or otherwise - it is permanently black. The LCD light works fine so you can see that it's charging, when it's full, etc.

This behavior has coincided with me waking up one night to find I'd fallen asleep on it. So…. what might we be looking at here? Any and all help is appreciated.

LG G5: Why is my flashlight heating to burning when using it in an app

Thu, 13 Dec 2018 14:09:53 -0700

I opened my OLG app to check a scratch ticket and i turned the light on and my flashlight came on fine as normal but within seconds it was so hot it actually burned my leg and i have a burn mark from it. Obviously this makes me nervous that i could be dealing with something that could cause a fire. I literally set the phone on my leg for no more than 5 seconds and had to move it because the burning was horribly painful. What could be going on???? This has never happened before. My phone usually over heats but ive never been burned by my phone before. Also this time the light waa much brighter than ive ever seen it. One small glimpse and its 10 mins later and i STILL have a huge yellowish black spot in my line of vision …. Like when u look at a lightbulb and look away and theres a big spot infront of your eyes. It wont go away. I have a headache from it and the searing burning. Please help. I really think my phone is going to die soon :(

LG G5: Primary Microphone not working

Mon, 27 Aug 2018 17:55:10 -0700

Okay everything used to work fine until one event less day when the main(bottom) Mic stopped working and I could no longer take calls or record voice. I'm able to talk on speaker on calls using the secondary mic. Even the camera recordings are only picking up the one side of the sounds in the stereo recording mode. Due to circumstances, I'm unable to send it into warranty. I already tried replacing the bottom replaceable module and there was no change. Any solution is really appreciated. At the moment, the only way to privately answer calls is to use earphones.

LG G5: Bottom 'chin' stuck in place

Tue, 14 Aug 2018 03:20:17 -0700

Hey there! Got a T-Mobile G5 (H830) used a bit ago, and I wanted to swap the battery out as it’s clearly a bit worn.

But I’ve managed to find out that the chin is stuck in place! Pressing the button doesn’t do anything, nor does applying some torque and wiggling the chin around while pressing said button. It seems to be jammed in place somehow. The side opposite the button has a bit more horizontal give, but it doesn’t help much. I’ve attempted levering it out with a plastic pry tool but to no avail.

Does anyone have any tips on how to get it unstuck short of dremeling the thing to bits?
