Big help needed - G4 Q&A, Help & Troubleshooting

Today I got myself an used LG G4, I am amazed by the looks of the phone but... The phone is really laggy, everything is slow, everything takes ages to save and load. When I take a photo, it takes good 3-4 seconds to save the photo even when the HDR is off. Camera is laggy sometimes, phone restarted when I try to take a photo with the manual focus, phone restarted when I tried to play subway surfer, played it for maybe 20 seconds and it restarted. Pretty much everything is slow as a turtle. Did a factory reset, it's running lolipop. I've tried updating over the OTA, said there were no updates. Tried to do it manually, stuck at 'connection to server failed' with the flashtool. I would smash it on the ground. It works worse than my Samsung S3 did few years ago. Facebook app takes ages to load, scrolling is really laggy. Messenger takes ages to load, everything slow. When I enter a chat, it takes like 6 seconds to load the text. Default browser laggy. Is there anybody who knows how to fix this or what should I do?

Just entered camera to play around bit with the manual mode, tried changing the focus... boom, restart
Tried Antutu benchmark test, went trough the first one and restarted... No idea what's going on

Now I got a bootloop for no apparent reason

Thats bad news bud,lg g4 is known for bootloop issue, does it have warranty. The motherboard need to be replaced.

Managed to boot it back up. Are you sure this is the motherboard? No warranty
Just checked CPU Z, core 0 is working, the rest say 'stopped'....

Looks like you have got yourself a previously bootlooped G4 that has had the big cores patch applied. Bad luck.

I got my LG G4 bootlooped too. Applied the core disabling fix. Core 0-4 are running as normal but Core 5 and Core 6 are stopped. The four running cores go up to 1.4GHz and the phone is still as fast as it was. I don't play much or multitask heavily but everything is as snappy as ever. Battery life is even better with the two big cores disabled. Are your four cores running too or is it just the core 0 that's stopped?

When I enter CPU - Z, only core 0 is active, the rest are off. Can you explain to me how can I try and active the others?
Nevermind, found out how, tell me. How long can the phone last on 4 cores?

I've only been periodically using the phone after the core disabling fix for a few days now. It's been working okay so far.

[Q] random reboots in every ROM lg nitro hd i

Hi Guys
Well i have install several ROMS wich as HO!NO! full throtlle, Cyanogenmod 9 an 10 stables and Nigthly edition, JellyBam and others that i not even remember and all of them always in some point they just reboots and im really hate it. I use wakelocks app and it works for a few days but eventually it reboot and he battery drain really fast, 8hours in EDGE and just a little chatting on whatsapp and a few calls.
i always wipe system, datvilks etc, im kind of new on this stuuuf but i think im doing it correctly.
Im starting to think that maybe its a hadware problem. Onces i ask some crappy tech gay in a store and he told me that i should buy another battery i dont know why, i thought that he just want to sell me the battery but i dont know.
Can anyone help me or recomend a ROM or something?
I just want a ROM that doesnt reboot and good battery life and i can do normal stuff. i dont care about overclocking or anything like that,
Thanks in advance
I would install a stock rom, either stock AT&T gingerbread or ICS for the Nitro and see if it still reboots. If it does, I think you have a hardware problem.

I would go here first: http://www.att.com/esupport/article.jsp?sid=KB413885&cv=820
This will make sure you are 100% stock. Then if you are still having issues you know that it is a hardware problem. Just make sure you do a full wipe after install.

Sparcots miui ics port is the only rom that has zero bugs, black screens, or reboots for me. I've tried everything else.

Another potential issue is your SD Card.
I've also noticed lately that my Nitro sometimes randomly reboots. I run with the CM10 Nightlies. The other day, after installing a new nightly, it was really bad, almost constantly rebooting. I took out the battery, removed the SD card and let it sit for awhile (like 1/2 hour or so). Then I put everything back together, reinstalled the nightly and it's MUCH MORE stable now (still randomly reboots, but the instances are much less).
Give that a try and see if it helps at all.
Good luck!
Hi All!
I have LG P936 Optimus true hd with vodafone v20c firmware.
It`s regularly several spontaneous reboots per day. I saved logs with one reboot

how it can be solved? Help please!
My solution has been to just stick with Gingerbread.. No rebooting, good battery life even with the stock battery, runs all the apps I need.
I do miss ics/jellybean, but I rather have a stable phone with great battery life than a pretty, unstable bleeding edge phone.
If anyone wants to build an awesome gingerbread/ics hybrid.. Then I am down. Lol.

Can you tell what happened based on the logs?
two P930s (NItro HD), one with hardware issues
I have two P930s. One of them is much more sensitive to ROM settings and I find I need to limit the CPU to 1200 Mhz or so to prevent random reboots.
The other one works well at full 1500 Mhz speed. This particular model seems to have inconsistent hardware build quality. It makes me reluctant to try any other LG devices (a relative has an LG dishwasher that has also been troublesome, with random shutdowns and error codes).
possible causes
1 - bad sd card
2 - bad flash
3 - unstable recovery .
for me , i have noticed the same , and found it fixed once i upgraded my recovery
1 - bad sd card
its rebooting without sd card
2 - bad flash
its rebooting on two v20c firmware what I used
3 - unstable recovery .
I use official kdz firmware only, not cwm
I' ve got the same problem. I've changed the sd card but it didn't work.
Similar issues here with a Nitro that a friend let me borrow while I'm waiting for parts for my other phone. Random reboots on several different ROM's including stock.
I'm going to try Kernel Tuner and up the voltage a little and see if the phone is more stable. wistlo mentioned limiting the CPU to 1200 Mhz and I think he may be on the right track. If the processor cannot handle being clocked to 1500, which is stock, then a common method (at least with PC's) is to either lower the Mhz or increase the voltage. Or both.
I just tried this a few minutes ago and I'll report back later.

My phone was still unstable. I decided to try a stock Gingerbread ROM and it seems to run very, very well.

Yeah, i remember downgrading to GB to root, didn't use it muchzbut it never once rebooted.
Bought mine last week on ebay brand new (packages sealed and everything), i let it fully charged and started using it.
Came with stock ICS and has been constantly rebooting for the past week.
If i didn't live overseas and didn't have to pay so much money to clear through customs here i would have returned it, but i'm stuck with it and searching for help.
Funny thing is i've gamed on it for hours straight and stability tests for more than 2 hrs and it never rebooted. Then i'll whip out the keyboard to type a message or install an app on play store...or simple web browsing and BAM!....reboots
I've changed to 3 SD Cards even tried without it, still reboots.
All wireless signals off, reboot.
Different ROMS/Kernels, factory reset/wipe, Battery cover off, diff. governors I/Os, Underclocks & Overvolts, tried it all....except going back to GB.
It kind of irks me to know that i came from a GB phone to upgrade to a "new" phone that can only run on GB stable.
It always crashes during some really "stressLESS" stuff, lol. CPU scaling problem maybe?
Also, with no SD Card installed and on boot i get a "SD Card damaged. Try Reformatting" error. Is it normal to get this error with no SD installed?

This definitely makes me think you've got a CPU scaling problem. If you're doing something consistent, like playing a game or stress testing...The CPU will likely stay at a single frequency...But in your case, once you start doing some other activity (which very likely caused a CPU frequency change), the reboot occurs.
Definitely try installing SetCPU and set both the minimum and maximum frequency to something midrange, like 1.2GHz. This way you're locking the phone to a single value (no scaling) and not the max frequency so you won't overload it. Then do what you usually do when it reboots and If the phone stays stable, you'll know the problem is likely an issue with CPU frequency scaling. If it still reboots, at least you've removed one possible reason from the list.

It was suggested in another thread that setting the governor to conservative 486 min 1404 max fixed the BSOD, so I tried it and haven't had a single reboot since I posted the last time. I was lucky if I got 30 min before trying it out.
I agree with you, definitely seems to be CPU scaling issue.
Conservative gradually increases the speed compared to the massive min to max spikes you'd get with ondemand.
I will try that with CM10.1 Rc2 with Wind Kernel. I got a few reboot when using my Calendar app for example, while low on battery.

[Q] Overheating 🔥?

I just got my Samsung Galaxy s6 edge white 32gb last night and I noticed that is over heating than it should be. I'm using it for Web browser and texting nothing that should cause to heat up. I also updated to the latest version.

Actually if it was overheating then the phone would automatically shut down to prevent damage, but yes the phone does get hot rather quickly. But I've had glass and aluminum phones before and they always get hot fast since metal retains heat.
Mine ran a lot hotter than a normal glass and metal phone, and it was laggy/jerky. I flashed the stock firmware to it, and now it's smooth and cool.
Here's How:

yes it does get hot once in every 3-4 days & when I say it means really hot..

Smart switch is not working for everyone. Hit or a miss thing.
My phone heats up to 44 C
What is the Warning Level is it safe till 45 or 50 Celsius ?
It happens when
1) On use of Google Maps while driving
2) Charging
3) When i use Sandisk OTG, to the extent that it stop the Transfer & freezes
4) Even if i Record Videos sometimes
5) While wireless charging
This is really bad Never had such a Issue
I agree with some of the sentiments here that the device can seemingly get pretty warm - especially when I tweaking things or using apps that use a lot of CPU or using the camera for too long. But I do believe a lot of it is related to the aluminum/glass case - I believe Samsung is basically taking advantage of the case as a though it were a heatsink - releasing all the heat into your hand/pocket/air.
This is truly the first phone i've had that manages to stay under 100° F even when cpu frequency is locked to the maximum and I'm playing very gpu-intensive games, provided that i'm not charging the battery and the phone is not in an unusually warm environmnt like a hot car. I should mention that i'm rooted and lots of preloaded software has been removed. I would download some sort of process monitor and check it to see if there's a misbehaving app to blame if this is happening regularly.

Hey,
I saw that you posted a solution when someone had problems with his S6 edge overheating. I've an S6 and I think I might have the same problem.
I was wondering if you could spare some time to help me. I posted my problem here. http://forum.xda-developers.com/galaxy-s6/help/help-s6-cpu-getting-hot-t3180011
I used Antatu benchmark and CPU temperature to test my phone and it got to 84.0 C twice, once when it was testing my CPU to it's fullest and once when it was testing game performance.
So I was wondering if you could run the test as well and tell me what temperature you got so I can compare. Thanks
I haven't tried your method yet but I will tomorrow.

For the record, mine just hit 85C while running AnTuTu. As far as daily use, it made a world of difference on my phone when I flashed the stock firmware the first time. The phone was terribly hot in my pocket when I was not doing anything, and it was SUPER laggy when I was. Not something I expected from this phone. After the flash, it was a Beast and ran MUCH cooler. It would get warm still when doing intensive tasks, but that would be expected from an Octa-core phone in my opinion. It does not get uncomfortably hot anymore, like it used to though. I would imagine it went WAY above 85C when it got hot before, because it was actually hard to hold at times.
If you have not flashed it since new, I would highly recommend it. I know it's a pain, but it's a one time thing that you never have to do again, and the benefit MIGHT be large. No guarantees, as you may not have the same issue, but I've received a lot of reports from people who have done it and they say it breathed new life into their phones. For me personally, it was DEFINITELY not a placebo affect. It was night and day.
With all that said, I've got my S6 Edge up for sale right now as I've moved to Apple for a little while. I continually jump around, and T-Mobile offered the iPhone 6 for $15/mo and I can trade it in 3 times in the next 18 months for free and keep paying $15/mo for the newest phone. I'm looking forward to seeing the difference in the iPhone 6s. If it sucks, I'll be trading it in shortly for another Android phone.
PS: AnTuTu final score: 69314!!!! Wow!!!
One more thing. To eliminate ALL lag and slowdown, I replaced the Samsung Launcher with the Google Launcher. What a difference that alone makes! Seriously, try that one thing. It's huge. The Samsung Launcher has some issue somewhere that they still need to address.

It should. As long as Smart Switch can recognize your phone model and download the Correct Firmware, the Flash WILL help the Heating and Lagging problem. If your phone is not recognized, then Smart Switch will not do anything. It's worth a try.
For me it happens especially when im playing arround with that samsung theme store build in app. I don't know why that app needs so much power to have that effect on the phone but for sure its something samsung needs to look at.
For sure they need to re-design that app from the scratch. Its like the "my first homepage" of theme apps.

Brand new G4 (H815L) performance issues

Hey fellas!
Just got a new G4 to replace my Nexus 5, and I'm encountering some heavily disappointing performance issues like:
poor 3D performance - games like Boom Beach and Smash Hit run just... bad. mediocre/low fps gaming, where my Nexus 5 did perfectly fine!
2D performance (UI) - sometimes laggy UI transitions, typing really quick with SwiftKey keyboard is impossible, it's like the phone can't keep up with what I'm clicking fast, feels majorly laggy.
Anything I'm missing? and low performance/battery saving settings I'm missing? what's happening... oO

There's an option somewhere to lower graphics in games to save battery...its on by default...at least on h811 it is...also in dev options changing all animations to .5 or off fixes any laggy experience
Thanks, seems to help a bit, but it's right on the fine line between actually helping and just a placebo.
I mean, some really visually simple games (Smash Hit) shouldn't run with such low fps, especially not when considering the Nexus 5 ran it perfect.
What about the rest of the UI?
I suspect that some of the problems I'm having with SwiftKey are software related (might not be optimized for G4 yet?), since I'm noticing some other unrelated performance bugs in it; emailed that to them.
I got H815L myself and it's pretty good.
What's your Antutu score?
Personal experience with Swiftkey is it isn't optimised very well at all and only runs properly with a handfull of phones if at all. I gave up on it a long time ago.
As for UI performance, I haven't noticed any lag yet. Games run great too.
I would point the finger at the Apps you're using and make sure you've updated the software on the phone to the latest version.
The nexus phones feel less laggy because the transition animations are so slooooow just like on iphones, and it's just there to hide any lag as it takes so long to open and close the apps.
You'll get used to G4 I have no doubt

I got 49081 on Antutu, and I'm running v10H and all my apps are updated.
I do suspect it's the keyboard app itself messing around with me, because I see several more bugs except for the weird latency.
And just for comparison, the game Smash Hit (on HIGH set on graphics) runs choppy with a Nexus 5 running it perfectly.
I know and understand Android, but why do I need to get a new $500+ phone with new hardware only to find out my 2 years older phone is more "optimized"?

Weird that you got 50k+ on antutu, most of the reviews I Google's were about 41k+.
How can I check what's choking the device?
I have nothing special installed; opened the box, turned the phone on, updated the latest OTA and then all my apps - games and some other stuff but nothing heavy that I didn't have on my N5...
Maybe I'll try to factory reset the phone some day next week and see the results.

Download a wakelock detector or something to see whats stayin active that isn't necessary...also are you rooted...if not you may want to do that...it will allow you to freeze and remove unnecessary and memory hogging apps and will give you a boost...i got rid of a lot of those day 1 and have had a great experience with my g4...we shouldn't have to do this to get the best out of this device but its the way android has gone...also with root you can try ctt mod and other performance boosters to really get the best experience...you can also get better battery life without the extra junk processes running in the back...there are many threads to teach you what can be done with the g4

Yeah, I pretty much know most of the basics of all the advanced tweaking, but since I have H815L the bootloader is locked, so rooting it is a bit pain in the ass.
Someday next week I'll just factory reset it and check again.
Thanks bud!
well ok.
Just did a factory reset and... Nothing.
So friggin disappointing, im completely clueless now.
right when the phone started up (completely blank after reset), downloaded and installed Boom Beach and Smash Hit, and the performance was still bad. Im so annoyed.
What the hell should i do? Why is my BRAND NEW phone is having poor 3D performance?

Root it and bump up lower clock speed on big/little cores with kernel audiutor...it will reduce lag and actually save battery as small processes cause it to jump around a lot on factory settings...short of doing this idk...

Weird that you got 50k+ on antutu,

It means his device is running cooler than yours. He mentioned some tweaks to keep heat down.
There is also the CTT mod (in development)but it requires root.
most of the reviews I Google's were about 41k+.

Actually i just checked 3 different reviews and the avg antutue score for the G4 is 49k. if you run antutu back to back 3-4 times it will drop to 44k. If it wont rise above 45k then it indicates a heating device with throttling.
How can I check what's choking the device?
I have nothing special installed; opened the box, turned the phone on, updated the latest OTA and then all my apps - games and some other stuff but nothing heavy that I didn't have on my N5...
Maybe I'll try to factory reset the phone some day next week and see the results.

How is your battery life in general sot/run time ?
can you try playing your games in a low light environment. So your brightness will be much lower. Do you notice any difference ?
I've had the phone for a total of about 4 days now, SOT seems about 3-4 hours, better than my N5 so I'm happy so far.
Tried gaming with low light / cold environments, doesn't seem to change anything.
Not sure about the throttling, due to the fact that the device is actually pretty cold... not sensing any extreme heat (my N5 was way hotter).
After that factory reset I get about 48k on Antutu, and I actually tried two different "heavy" games (NOVA3 and Asphalt 8) and they run OK...
I genuinely have no idea what's the problem, so instead of rooting and tweaking stuff that seem to not have to be tweaked for others, I'll just wait till I get back home and compare the gaming performance with friends' devices.
If something goes wrong - warranty it is.
Man, I feel you! Been dealing with laggy UI and cursing my choice of purchase since day one. Anyways..
For games - have you disabled 'Game Optimzer' option from 'Battery & Power Saving'?
For laggy UI - Swiftkey is laggy as ****. So try Fleksy, it's a LOT smoother, I barely notice any lag (although it does hiccup once in a while...). As for general performance, you have to accept that some animations will be choppy - that's just how LG UI works, there is no work around. For me the phone was chugging a lot before I uninstalled Inbox by Gmail, after that the phone regained it's speed and it's pretty damn smooth now. It still stutters here and there but ...what to do. Also try delobating it and removing any unnecessary apps and services (you don't need to root for this).
OK so some updates.
Rooted the phone, debloated the s**t out of it, even managed to got to 5h 2m screen-on time with that lol.
Tried to tweak lots of other things as wellwell, got me some great bootloops in the process. eventually I practically totally wiped the system and flashed a 100% clean one.
Smash hit (on High setting in graphics) and Boom Beach still work a bit choppy.
NOVA3 seems to work ok.
AnTuTu is about 50.5k.
I seriously can't figure out what's the problem.
the 2d phone UI seems almost perfect, and the benchmark score seems OK.
What the hell could be wrong?
Is there any more testing (games/benchmarks/logs) I could do to try and figure this out?
It's going to take me another week till I go back to my country to check with a different H815L. Asked a friend with the US model, she claims Smash Hit works flawlessly fluid. can't understand that.
I find it funny, the fact that I might ask for an under-under-warrenty device replacement just because couple of games run bad.
Hoping the XDA gods would help me in some way, before heading the noob warranty-for-nothing route.
Thanks!

Dude i has the g4 H815L and it is works fine but maybe it becouse the root.
I has the device for few months with stock version of lg and my g4 works very good and when i play games like Goat Simulator he got hot if not very hot but if your device don't get hot becouse of games so for sure you won't get high preformance.
Plus my bettery works fine and my phone can work perfectly and smothly with smart watch and survive one day with out any problames.

Every CPU (SoC) is unique. Remember, even two identical CPUs can deliver different benchmark results, thus have different real world performance. Unless there's a software issue you haven't found out about yet, it's also likely that you just got a bad one.

Don't even hesitate. You paid for it hard earned money under the condition that it works as stated and advertised by LG. Now, as you told us, it does not. See my point?

Performance issues and low Geekbench 3 score

Hey,
I have a problem with my Nexus 5X. Overall the daily usage is pretty much the same as last week, but when I will start a bigger App or a Game the phone becomes slow. I closed all apps and restarted the phone. Then I started the Geekbench 3 and the score is so low! I don't know why. I attached a screenshot. Can anyone help me?
What firmware are you using?
Dont look at benchmark's score, it doesn't reflect real performance of phone, e.g my sgs3 gets 40k in antutu but nexus Just 45-50k
Lower performance in bigger apps is caused cus when CPU reaches 55*C it turns off cores to reduce heat, you can change it with custom kernel.
I have the newest security Patch. And the Geekbench is just to demonstate how slow the device is. The Performance issue Starts when I open a game or a big app. The phone is cool and it heats up minutes after playing the game.
But is it slow in daily use? Or Just in big apps?
Look on ur average RAM use, maybe some apps make ur phone slower like fb messenger (it can take even 500mb up)

as already said, phone benchmarks mean next to nothing these days. closing apps also rarely helps speeding up a device. removing apps from the recent-screen doesn't close/stop an app btw, they redid that quite a while ago afaik.
and as a last note: restarting the phone is a very resource intensive and long process and can easily take until long after you are already able to use the phone again (mediascanner, background/system services and apps starting...)
I don't have the Facebook Messenger. Ram usage is around 1.3 GB. And it's everytime. Not only when it's restarted. I don't have Cleaner Apps or security Apps. The Speed changed ca. 2 days ago. Last Tuesday everything was fine. Benchmarks were fine, Apps were fast and everything was smooth. But then I don't know.
So that's very weird. What did you install whole last two days?
Only the game Smash Hit. I have wiped data and Cache. It didn't helped so I Uninstalled the App. Still the same.
Hm, So I'd recommend reinstalling ur rom, what would you say about it?
I can do that, but its really annoying when I must Reset my phone until a week.
So it has just a week?

It's my first week with this phone. It's completely new!
Wow So I'm surprised bro. Don't you have any another issues typical for Nexus like yellow screen, slow AC charging to make a complain?

Yes. The yellow Screen. But its fixed with the Developer Option "cooler colors". Buildet was this phone here in October 2015.
So, you can try to make a complain or Just reinstall rom /change kernel. No other way
I don't want to loose my warranty .
Edit:
I have wiped my complete Cache again and the score is a little bit better. Also the game. It's faster but not as fast as before.
If I'm not wrong you can take back ur warranty by flashing stock and locking back bootloader
I don't want to change anything. Are there no other possibilitys?
Solution
I had the same "problem".
Try to lock your phone and leave it to rest for few minutes. Then unlock the phone and run geekbenchmark 3.
You should get normal results now (~1230 for single & ~3500 for multi-core).
I hope this helps.
I'm facing exact same problem, bought my nexus 5x almost 1 month ago I did the geekbench but the scores were very low specially single-core, so I head up to couple of forums they suggest to reinstall the geekbench app or install the 64-bit version of it. I didn't get the 64-bit version of the app nor there is any stock setting on the phone to run apps completely on 64 bit. ( Note: Im no pure stock, never rooted, locked bootloader )

LG g3 restart loop

I've had my g3 for 2.3 years, and it suddenly went into boot loop one day after charging the phone. The boot loops for around 3 or 4 times then stopped and stayed shut down, got it to repair shop yet they claimed that it wasn't hardware issue but software. I doubt that as I've updated my g3 to android 6.0 last October and has been working fine since. However, just to note that I was charging with a broken cable last time before it went into this boot loop. What's the problem with the phone and how can I retrieve my stuff as i haven't backed up yet. Is this problem fixable as I am trying to avoid factory reset and data wiping at all costs.
I had the same problem , it happend suddenly 2 days ago and i am trying to solve this stupid problem but so far no solution.
I upgrade it to 6.0 then downgrade 5.0 tried different versions but no solution.
Wierd thing is just started from nowhere.
Kind of Cpu and heating related but not sure what can be the solution cuz when the phone is colder not restarting that much like warmer.

I haven't tried a new battery, yet I have two batteries, one was the original and other was bought at the same time I got my phone 2 .3 years ago, I have also tried to boot my phone plugged in, and even safe mode, but no success. Both methods only took it into the boot loop.

First thing i bought new battery but didnt help at all.
It is most probably cpu heat sink problem , that heat sink doesnt work anymore i guess . Now phone works like normal with low cpu freq. but a bit slower ..
One day i will try to change heat sink on cpu but dont know when

So do you have similar problem? and how did you get it to work at low cpu frequency, I don't mind it being a bit slower as long as I get back to my data on my phone.

I have same problem but mine at least opening .. when you can not start the phone , you can not change the freq of cpu.
I did mine with root and app called "no frill cpu"
For starting you can try to put your phone in to freezer 2 or 3 mins (not make super cold) and then start it when it is cold , i managed to use my phone like this around 10 min. so then u can change cpu freq
But today it turn off itself and so far couldnt turn on again ... looks like it gets worse in time..

No problem , tell me if it works.
I just try right now mine and all day it was restarting but i put it in freezer 2 min. and tried and it turn on ..
I am wondering all problems are same from cpu
Few mins. ago i opened up my lg g3 and apply heat sink on cpu chipset and so far it works really better than before
I even tried normal cpu freqs. and it didnt restarted , before using heatsink it was not even possible to see main menu on high freqs.
I was already thinking to buy new phone and spend so much money but then i give it a try and it works. I dont know how long it would help but so far so good.
So i would recommend anyone who has this bootloop problem to try heatsink gel on cpu if still problem continue then you can throw away the phone i guess
Hello, I've battery problem and it keeps restarting by itself, So I decided to buy new battery and with new battery still problem exist and it's random, after 2-3 min usage it restarts.
What should I do ? the phone was working very good a few days ago and that battery was fine until this stupid restarting happened and even I flashed the stock Rom but it didn't fix it.

Thanks for videos, I don't know how but I was able to use the phone for 3-4 hours and for test I used Antutu benchmark and I got 53.000 score, When I tried to charge the phone it turned off and I tried to turn it on again it stuck on Lg logo and I heard some noises sound and phone stuck on logo ( sometimes it has boot loop), For now I turned off the phone and tomorrow I'm gonna buy Thermal paste, Hopefully it will fix it.
Did you have the same kinda of problem ? Like phone stuck on Lg logo or it turn off after you try to turn it on .
How do I know if my G3 is dead? It doesn't do **** when I try to turn it on, it just vibrates and stays there. When I connect it to pc, it detects a connection but nothing happens. This happened earlier this morning and it doesn't want to boot back up no matter what I try.

My phone suddenly turned off and repeated to try to turn on itself but sometimes it was just bootlooping on lg logo sometimes just seeing lock screen and turning off . Noise stuff i dont know but mechanically there is nothing to make sound i think so dont know from what but i never had it.
You can try another working battery and software format. If these doesnt work then you can make thermal paste thing .. but if you think it is easy to do thermal thing then just start with that.
There is no point in software changes -- it's a hardware issue. I don't understand why no one checks the forum before asking -- there is a ton information written on here alone, and how to fix the issue.
You need to fix the loose connections and heat problems of the phone.
Thats right. All you have to do is applying a thermal on SoC. It did work for me
