Guuuuuyd eureeeka. I did found the solution. Me too i was experiencing the same issues. And i tried several solutions and nothing worked for me. But i found that the problem like u said was in some carriers. So the thing is the phone goes off when a change in the signal is made from 3g to 2g or 4g. Between the catgorie..

So what i did is to force the 3g on the settings. I was surprises. The result is pzrfzct cz i am no longer experiencing any shutdown. Try it ^^

Problem solved

LG services guys just called me and said the problem is from IC Power on the main board. So I went to LG services and they changed all of the main board and problem is gone.

They said this problem happens to some of G3 s that are bought in early days of releasing LG G3.

Hello fellow Users . I am from Poland and i have my LG G3 since a december 2014 [ half year till now ]

Im writing to you with my issue ; So i was checking time on my phone , then i tapped twice to turn screen off and put away my phone on desk .. 15~~20minutes later i picked up my phone and tapped again to turn it on.. nothing happened , I also tried to click on the power button but nothing happens .

Next after , I replaced battery from back and tried to turn it on ... once... twice.. and nothing . Also hard reset combo didnt work ( power button + volume down button )

I plugged it to the charger , pc and still nothing .

Its like my phone just said "fk u " and thats all : //

Maybe it is hard to believe but it happened..

I have my phone rooted ofc , but i dont have garbage apps on it ..

Do you guys know what it can be wrong ? Maybe battery just died ? ?

Please help .

Helppp!!!! I am also facing this problem. At first I thought it was because I used SetCPU but after uninstalling I continue with the problems. I am on CM 12.1
[G3 Q&A, Help & Troubleshooting] 0nebukadnezar0:
I bought mine on ebay, that mean not a new device (July 2014) have directly installed CM12.1, use it 2 weeks without this issue, it appears only after the installation of the HTC M9 camera, after the uninstallation, have still the unexpected power off.

Will try a factory reset, if this could not help, replace the battery, but at the end I will probably open y case by LG to replace the device (or at least the motherboard) because I have the feeling this is an hardware failure, not a software issue.

As many of you have noted maybe this is a question of what provider we have. Maybe something goes wrong with mobile signal.

What about if this is a question of a flaw modem firmware? I am having the problem with the modem of v20h. What about yours? What modem are you using? Are there somebody here that has no the problem to tell us his version?

I have the same issue but my phone restarts in areas with low signal or when the data connection changes from 3G to Edge in a bad reception area.

It looks like LG is aware about this issue, because they don't discuss or try to find a software solution to this issue, they direct proposed to repair (hope correctly) the G3.

As I need a backup device, I've ordered the Asus Zenfone 2 (my wife will use it later) as soon this device is delivered I will send back the G3.

But if I leave the battery charged over 70% - 80%, I don't have the issue, of course it's not a solution, only an indication.
[G3 Q&A, Help & Troubleshooting] hoangngubinh:
Hi there. I bought my G3 D855 Vodafone 16GB 2GB RAM about 1 year now (cause i bought it to take picture and record my baby when he was born,lol).

Ok, first my phone is not a new one (like new 99,99%) and its working very good until now except 1 thing, ya thats it ==> AUTO RESTART OR SHUTDOWN.

When I bought it, it was on Lollipop already, stock ROM (not remember the build version). But after 2 months using, its starting got this problem. Sometimes, i need pulg in the charger, few times need take out the battery.

After 6 months, I decided to root it and flash Bliss Rom (u can find it in the G3 forum here). After few days, the problem came back.

Now, after I read many topic and try to do 2 things:

- Change battery (because, sometimes yes just sometimes I noticed before my phone shutting down it not sudden shutdown without warning, it showed a message somthing like: "Battery..............", it want to say the battery is not right or something, Im not sure and remeber exactly). But its only very few times. I dont know anyone there have the same as me. And with this I can press Power button to turn it on.

I bought a Polarcell 3100 mAh from Germany shop via Ebay. Just changed into it today, not yet have shutdown problem or auto restart, still following.

- Force my phone under 2G signal. As myself, the problem showed up when I turn on 3G, got a call, took a picture, use GPS, most times with me it will happen. And when I'm on a call and turn on the speaker, it will happen too. Still following and will update to you guys/

Anyway sorry for my bad English. I think it is hardware issue and pity for who like me, didnt under any warranty we just try to find out a way to keep this problem as minor as possible, right?

P/S; my serial number starting with 410 too, due to a guys from few pages before notice that from 410 serial number phone working flawlessly, sorry its not!!!
[G3 Q&A, Help & Troubleshooting] amagdy81:
So I changed the modem to the 20i and I haven't got a restart since then but I did one thing also which is I just stuck a small piece of paper underneath the battery to make it fit more and no gap. Since then I haven't had a restart not even in low reception areas.

As per previous discussion, can someone tell me if the 20p modem or the 20i modem is newer? I have noticed that with the 20p modem, the data signal changes quickly without a delay and reception is better (don't know if it is just a feeling or not)

Hi.

My G3 is shutting down too (since yesterday doesn't even boots... keeps restarting at the LG logo) but I think it's because a faulty battery. I measured de voltage directly at the output pins of the battery and the result was 4.24V. Battery specs are 3.8V :eek: I think this value is too high... but I'm not sure :confused:

Has anyone here already measured this? What was the result?

Thanks
[G3 Q&A, Help & Troubleshooting] tarzan2003:
Already managed to measure two other G3 batteries ;)

battery 1: 80% charged => 4.08V

battery 2: 14% charged => 3.65V

battery 2: 100% charged => 4.25V

It seems 4.24V of mine aren't too much. But I'm sure mine is dead because I used it on the other two G3 and the behaviour was the same as in mine ;)

Thanks anyway

My LG G3 D855 is suffering the same condition, now it can only survived connected to a wall charger or an external battery, otherwise it will keep rebooting. What is it? The battery? or the mainboard?

If i replace the battery would it work normally? I am in Venezuela and do not have any other G3 users at hand to try with another battery, my G3 warranty expired (very few days ago). VERY early batch. It is a SEA version from Hong Kong. Contacted LG HK today, waiting for reply. My phone also has the cracks, and i only can survive attached to a power source.

Best bet would be to order an Anker batt from Amazon?

My new battery Polarcell working flawlessly. No high temperature, quite durable (sleeping 10hours with Wifi turn on and only loss 1% battery).

Just need to notice u the Stock rom version in my phone right now is v20s. And this ver did happen 1 time auto shutdown count till now (after i upgraded it about 1 day), after that no more. But the ver which keep phone awake 350+ hours is the ver just before this one (before this v20s), i didnt remember exactly what the name of the ver, u can check with other.

LG G3 Random Shutdown, or motherboard issue

Hi Guys,

I tried all possibilities to fix this, changed battery , bought a new battery. Re installed software, cleared cache, reinstalled all mobile radios, and complete OS and none of it could actually fix it.

It always used to show a 100% battery, and it would never fall down. After say 5 min phone will automatically shut itself, else once you start using WIFI or make any calls, the phone would again start to put itself off.

When approached the customer service, they have claimed that this could be a motherboard issue, and motherboard means quite expensive, and until now I have no further updates from them. My phone D855 or LG G3, is the Korean model shipped for the middle east, and its no good.

Also the LG software team sucks big time, they dont have anyone who is giving proper updates unlike HTC or Samsung does, after the Lolipop update my phone has had battery issues like most of others, and until aboout 7 months there has been nothing that really came from LG, and even Andoid 6 ( Marshmallow) , we dont know what is the status or when it would arrive for us.:mad:

LG except for the display, the phone actually doesnt do that well, and I wont recommend it to anyone considering the fact that phone was handled with utmost care,and never dropped as well. :fingers-crossed:
