LG G4 Issue - G4 Q&A, Help & Troubleshooting

The problem with my phone is that it doesn't turn on. It happened yesterday out of the blue when I was doing some practice questions on my computer. I was bored so I looked at my phone that was on the table for notifications and the screen didn't turn on. I don't even know what's the cause of it. I took out the battery out of the phone and held the power button down for 1 min. I also plugged it to multiple chargers without having the battery in it. There were no signs of life. No screen turn on, no charging indicator, nothing. I suspect it's a motherboard issue.
Has anyone had this issue before? If so, is it a motherboard issue? What is the cause of it? Are there other factors that are in play? How did you solve it? Thanks for your help!

you sure your battery isn't dead?

The battery was at 75% before it happened. Now the phone doesn't even charge.

if it doesnt charge it might be the charger port. do any lights come on when u plug in usb cable to charge?

Nope, nothing happens when I plug it in. But the battery was at 75%, so shouldn't the phone turn on?

take it to a shop, get them to test another battery

When I fried the mobo in my g4 that's exactly what happened except I was doing things that stressed the poor device out.
The warranty is extended for certain models I would try the LG warranty department.

Need help charging problem

when i connect the normal charger to the phone, the charging light appears and the phone does not charges! on USB to laptop its ok, the phone charges , but on normal charger it does not charge...
any ideas???
I'd say the problem's most probably with the charger. Try using a different one to see it the problem still persists.
but why does the charging light is on ? and the phone says it's charging... ?

Its definitely a problem with the charger. One loose connection and it all goes hay wire!!
The light stays on because some current IS going through to the phone....
Yes, sounds like the charger.
As a side note, I have an external power pack, and if I plug it into the phone (power pack switched off), the charging icon appears - just on the DHD, not on other phones/ipods. I have learnt to live with this as a minor anomaly of the power pack, but just goes to show that the charging logic is not particularly clear

dhussa said it. The charging light might still be functioning because of some little current going through.. although that might not be enough to charge the phone.
Just try a different charger to ensure that we are thinking in the right direction. If the different charger works it'll eliminate the possibility that there's something wrong with your phone. (Although I doubt it since it is charging via USB.)
yeah...well i still hope it's a software bug :-s since a saw a similar thread and a good battery calibration might just be the cause
oh well...thx guys ...

[Q] Stuck at 0%, won't increase even if charging

So I had this phone for a while now its starting to act up.
I pretty much killed the phone to 0-1% then plugged it in to charge and left it for 8 hours (sleeping), I wake up and find it only charged 3%, wow seriously? I fiddle around with it and it goes back to 0%?
Problem? Anyone had similar issue?
P.S I did search first, couldn't find any...

It's probably a dead battery or hardware issue. I'd go to your seller and ask him what to do. Most likely you'll get a new device!
TIP: Try to charge it through your USB-port in your laptop/pc, perhaps the power supply is damaged?
I've had this problem. It's not really a problem, and it's easy to solve.
Find a different charger, like an iphone charger (worked for me) but other chargers than the HTC One will work :-D
Sent from my HTC One X using XDA
Its completely turned off now, im charging it but the red light just keeps flashing on an off, gonna leave it in for 1-2 hours and see how it is.
Okay, I left it for around 1 hour but the red light has stop flashing, problem?
Anyone? I tried another charger like the iPhone but same result... HELP!
Have you tried holding the power button down for 10 seconds, it equivalent to a battery pull, and then see if it will charge.
John.
are u using custom recovery?
Now, the CWM Recovery has a bug that the phone cannot be charged when power off
I've faced your situation, I got into bootloader, flash back the official recovery first through bootloader, try your phone can be charged when power off

I can't turn the thing on but I connected the usb via to the computer and the notification is blinking red, I assume its charging, the thing is yesterday I unlocked the bootloader (was at 95%), rooted it etc then started playing with it until it reached 1% and left it to charge overnight but it only went to 3% :/
Hopefully it charges fully after 8 hour of leaving it plugged in to computer while I go to work.
I would not leave you phone charging unattended, as lin-ion battery sometimes vent flames, when they are faulty and you don't want your house burning down.

Hmmm, I might bring it to work, but I can't get it swapped due to bootloader, fml.

That tip about plugging it into my laptop absolutely worked! I was panicking for a bit because my phone was stuck at the 0% boot screen and I thought it was bricked. But I followed this tip and it instantly started charging. Thank so much

[Q] Need help

So I'm currently using the Suarom ROM, and for the most part it's been working fine. Suddenly I have a problem. Last night I plug my phone in to charge and suddenly it won't charge. I tried with two separate chargers.
It's still a new phone, so I can bring it in for warranty work. I just want to make sure I take all the steps necessary to "un void" the warranty. I'm a Rogers customer. If anyone can help I'd appreciate it.
Theres a thread in the DEV section that provides instructions of how to completely un-root and restore your device to factory before you turn it in for services.
The only problem is, my battery is at ten percent with no way to charge. The strange thing is that when I plug the phone in, the charging symbol appears. Just doesn't charge. Any idea why that would be ?

Tried different chargers? maybe plug it up to your PC see if you can get some juice that way? i can see the cable/charger going bad before the usb port on the phone ( but **** happens ) 10 percent should be good enough to get your phone back to stock though, i did it at 7 percent not to long ago, you just cant play around you have to click and run and get it done so it does not die. then if it dies after at least you are stock and can just turn it back in. but to be honest for a charger problem i VERY SERIOUSLY doubt they will be looking at Software and roms. thast a defect, and i think they will just do a clean swap----JUST LET IT DIE so they can not turn it back on in the store..lol
Ya could have a derpy battery and the phones fine.

Yeah, I have tried three chargers with no luck. Haven't tried a PC yet but will after work.
So if I'm getting the lightning bolt charging symbol, odds are it'llbe the battery rather than the port?
take it to best buy or an at&t store....and just say, hey i think i may have a bad battery do you have one i can use to see if my phone will power on and recognize the charger after it is plugged in. then you will know, unless you have an extra battery just laying around.
I had a similar problem like this before. Try charging with the phone off.
OR
If you want to troubleshoot and isolate the problem, try getting an external battery charger and a spare battery.
If you charge your stock battery and it charges with the external charger, your phone may be the problem. If not, then it's the stock battery.
And with the spare battery, try charging it via phone charger.
These are the possible ways I can think of at the moment. Hope this helps!

charging issue

hi, i hav been facing charging prob, my does not charge whn its remain on rather drains batt more quick but it was charging whn i turn it off but slow. i thought its the issue of sense 5 so i degrade to sense 4+ viper 3.8 but it got worse. idrained my batt and than put to wall charge for whole night but the charging led kept blinking and than it disappeared than again i unpluged and plug the cable to phn than it starts blinking and than again blinking of led disappeared. i thought it will take time to become stable so i left it charge for whole night. in the morning led was disappeared and i tried to turning phn on but it did not respond. than i plug it to pc and it started blinking without disappearing of led. i left it for the whole day to charge but the led didnt turned to green due curiosity i turned phn on and batt lvl showed 20% ......so plzz any 1 tell me wht can be the solution of the problem plzzzzzzzz:crying::crying::crying:
You probably have a dead battery...Someone who has seen this problem before could confirm.
The way you write is pretty hard to read, so you might wait a while until someone does confirm this .
1. Never charge the phone for the whole night.
2. I had the same problem. I changed my charger and now, it is perfectly charging. Try it.

thanx for suggestion, how much do i hav to pay for a new charger??
But you said you left it to charge via USB cable on your PC and it didn't charge properly. If you used the same USB cable with the charger, then the cable might be to blame. You should try a friends cable before buying a new charger.
If the charger does not work with the same USB cable you used to connect to the PC, your battery is most probably dead.

Charging all night isn't an issue.
The battery will charge to 100% then drop to 95% and back up, will cause no damage.
Also smaller and often charges are better for the battery as it slows the formation of crystals so the battery holds its capacity longer.

If you have used 2 different cables to charge and none worked properly, that is probably too big of a coincidence. Your phone has something broken; it's either the battery or the charging circuit in the phone. You should take it to a specialized phone service to see what's wrong. They will also try charging it before disassembling, and if there's nothing wrong with the phone, they probably won't even charge you anything.
If indeed they have to disassemble it, you should ask them if there will be any visible differences once they assemble is back. I had a cracked digitizer on my old One X and took it to service and replaced the display+digitizer(they come together) and, although the screen was new, it did not fit as snugly as before, so you could see light leaking out the side margins of the display.
They probably had many of these phones under repair and should know if this will be the case with your phone.

Despite replacing USB power board & Sim/Microsd holder still cannot get charge

Hi guys
Just cannot seem to get the thing to charge.
Tried different charger/usb cable. Got completely new USB power board. Sometimes the battery icon comes up on the screen when i turn it on of just a battery with a bit of low red at the bottom of it. It won't turn on. Theres not even a charging beacon light on top of the phone to indicate charge.
What does this usually show? Bricked phone, bad motherboard or bad battery?
Cheers.

Is the error that comes to screen
"USB not supported"?
not getting any error mate. It is totally dead.
I did buy a new battery which had 4% life left. Not enough to copy 64GB data to an SD card.
It seems it must be the main board which is damaged. I have replaced the power board and the middle ribbon cable. This has to be a mobo issue unless u can think of anything else?

I still don't think that's mobo issue. Try this before you intend to replace your mobo.
Plug in charging using any charger other than wall charger. Use a power bank or anything and when the battery icon shows up that you described in first post(the red icon) leave it there as it is and let it charge over night. Try powering up in the morning.

I dont get any icon on the screen when I plug a charger in. Even the powerbank... When i plug that in I get no beacon light on the top of the phone to indicate charge and also no icon on the phone screen. The phone never gets hot when it charges and the charging device never gets hot. Stone cold both of them.
What do you reckon?

I think your phone needs a doctor ?. Take him to the hospital (service center). Last resort before going to service center is take the battery out and charge it using one of those battery charger.

The annoyance is though its not the normal kind of battery you come across...
Take a look here: https://i.ebayimg.com/images/g/ScMAAOSwVm5Y-v50/s-l300.jpg
It has a strange connector on it. one of which I have never seen before.
How do i find service centres located in Australia?
