Overheating!!! - Verizon LG G4

My phone will overheat at random times right behind where the camera sits. The only thing I've noticed is that usually my connection is on 3G when the temp goes up. Any advice on how to fix or diagnose the problem would be greatly appreciated.
Thanks,

I have the same problem when in 3G areas. The battery should be getting drained very quickly as well. Only way to stop it is move to a 4G location or switch to airplane mode. This should be fixed in an update.

Or just turn off mobile data, considering you'll lose all text, and phone capabilities on airplane mode.

The battery does plummet. This did not happen with the first phone I had, which I sent back due to missed touches. I should have kept that unit

Maybe a bad battery, maybe bad device, try switching the battery first. If that doesn't work then switch out the device.

I've had this overheating issue on and off since day 1 with this phone. What I've found is that some 3rd party apps/widgets just don't play nice with the g4. Uccw is one. My phone was getting super hot, camera and top of screen. I booted into safe mode and it cooled right down, so I knew it was an app most likely causing the heat. Then I figured it would most likely be the launcher or one of the widgets I was using so I started with removing widgets. That seemed to work pretty good, no more insanely hot screen issues for a few days, but then just today I downloaded an app from play store and next thing I know my screen is nearly burning my face! So, deleted that one too.....seriously can't wait for root. I might be scrapping this g4 and going back to Sammy. Idk

[Q] Extreme battery drain (CM7)

No idea what happened here, but my partner's myTouch Slide is eating the hell out of its battery.
Two days ago I updated the phone from CM7 nightly #41 to CM7.0.3 Stable. The day I performed the update, she noticed her phone started complaining about low battery levels. This was only after about seven hours off the charger, with extremely light use.
A quick look at the Battery usage menu showed Display at the very top with 80% of usage... but it had only been on for a whopping seventeen minutes. The phone was sitting idle almost the entire day.
I have tried everything possible--full wipes, installing several different ROMs, restoring to complete stock--the display continues to drain the living hell out of the battery. I know screens take a lot of power, but this is ridiculous. Before this started happening, her phone could easily go two days before needing to be charged.
I'm starting to think the problem is hardware-related and there's some damage to the phone. It's had some minor water damage in the past--a partially-cracked window allowed some rain to get on it, enough to cause the phone to shut down and refuse to turn back on until after a night in a bowl of rice. She isn't exactly gentle with her phone... (if we're forced to buy a new one, I will make her be gentler... lol)
Any ideas? Anyone else have this problem?
Update: It appears as if the phone isn't going to sleep. It was taken off the charger an hour ago and has been in a pocket with the screen off for the whole time, and the battery usage screen is showing the phone was awake the entire time.
I had similar problems in the past with a previously owned G1 and later with an EVO 4G. I'm not sure exactly what caused it but what fixed it for me was flashing a different kernel. Although I wouldn't sudgest you do this it might turn out a bit problematic.

I tried flashing a different kernel and the problem wasn't resolved. Unfortunately it looks as if the problem is hardware-related and the phone needed to be replaced.
Oh. Well sorry I couldn't help you body. I think I'm having a hardware-related problem as well with my current phone (MT3GS) it seems to be having problems with the network when I try making calls it reboots. I flashed cm7 and it didn't reboot anymore but now when I attempt to make calls it doesn't make or receive them. I think ima need to have it replaced as well.

Battery Drain
I have a mytouch 3g slide with android 2.2.1. The battery only last 4h 35m. it all started when i updated all the apps (including the android market). Reset my phone downloaded no apps but updated the market still the battery drained. i uninstall latest android market and battery last for 1d 9h 45m 15s. I believe that did the work.

[Q] Galaxy Nexus shutting down

My GSM Galaxy Nexus has been experiencing random shut-downs, especially when it is in my pocket. I haven't noticed any problem with overheating and I tried rooting it and installing the latest version of ICS 4.0.4 directly from Google's source.
I also have Lightflow installed, but I doubt that it causes shut-downs, since I've only heard of reboot problems.
I suspect it could be a problem with the battery because, whenever this happens, the charge level goes down by at least 5% or more.
So, does anybody know how to remedy this? Or will I have to exchange the phone?
This has happened to me a couple times. I never know how long it's been off. I'll take it out of my pocket, and it's just totally off. I hold the power button and it starts up. Very frustrating bug though... as rare as it may be.
I'm still stock, unrooted 4.0.2 using the extended battery on VZW. Holding out for the first update, then we'll see...
Just so you know next time that happens grab a log and post it. Also, if you battery is down, try wiping stats, that usually brings it back.

Sorry for being such an ignorant and a noob but by log you mean a crash log right? Which is the best way to obtain them?
This happens to me about once a day. I'll come back to the phone and it will just be off. I aslo have root and lightflow installed. What's the best log to get?
It was the battery for me...
This was happening to me too, almost every time I took my phone out of my pocket, it was turned off.
After a couple weeks of troubleshooting and googling, I figured out what it was. It was the phone getting "twisted" in my pocket from sitting and standing. If you twist your phone like your're trying to wring water out of it (not too hard), the battery loosens just enough to cause the phone to lose power. I fixed this by taping a thin piece of foam to the inside of the battery cover to keep the battery in place. Makes the back of phone feel firmer too.
Hello !
I'm experiencing the same kind of power off.
Very often it's in my pocket, but sometimes not.
I've leave the debug mode on for the day, so last time it happens to me i've save a "abd bugreport" to a file.
Is there any clue that can be found in this file to know why the phone shutdown ?
Regards,
Antoine
EDIT : I have YAKJU 4.1 stock ROM, no root, no unlock.
I noticed a while ago before seeing the videos that if I banged my GN against the table a certain way against its bottom left corner that it would shut down. I solved that like the poster above by putting an extra something in between the battery and the cover (paper). That solved lots of the problems I had with my phone shutting down when I put it down on hard surfaces. There is though, I believe, a second software caused issue for some of the shutdowns. I still pick it up once every couple days to find that it's off. I've banged it, tapped it, twisted it, and I can't get it to shut down physically like that anymore.
I'd like to know more about how to pull the logs and find out what's going on.
I've had my Nexus for three days now, and I've had several shutdowns. Two of them were during a phone call, and the other two were during a workout using micoach app. The twisting/pocket option doesn't apply to me, because during the calls I was holding it in my hand, and during the workout it was strapped to my arm. I also have lightflow, and will uninstall to see if there is any difference. Running totally stock unrooted 4.1.1. This is making the phone totally unreliable, and I will return it if I can't get this fixed soon.
Every would have had that problem due to how poorly Samsung constructed the battery slot for the battery to fit it. What I did to fix that problem was take out the battery. Even from time to time rage quit and rip the battery out while the phone was on. And put it in, and push it a bit up toward the camera. That fixed my battery issues. Others have put a foam thing (sorry I don't know the name) where the battery slot golden things were so the battery wouldn't move. You can also try that.
Galaxy Nexus-codenameandroid rom
I uninstalled Lightflow after posting my previous message, and since then have not had any random shutdowns. All calls are performed flawlessly, and I've used micoach several times again (this was when the problem was most obvious) without any problem. I haven't changed anything else, so I'm pointing my finger at Lightflow. I'm installing it again to make sure it was the cause, will report back.
Regarding the battery problem, I've been looking at it and can't see how it can become loose. It is really tight, and there is no spare room to add any kind foam. Maybe thye have tweaked the design on later batches? My GN was built March 2012.
I had the same issue and it was caused by an app. The app "Boid", a twitter client still in beta, was causing the reboots. The reboots occurred once or twice a week, they happened on 100% stock ICS, 100% stock JB, custom roms also.
Like the above poster, I uninstalled LightFlow and am no longer having any issues. I'll try and get in touch with the developer and see if there are any logs I can get to help.

tab gets flickering screen and reboots

I dropped by tablet battery down once and now every so often the screen flickers with vertical lines and this is followed by loss of network and the thing reboots.
I've read this to be a battery problem.
Warranty is still active but I've rooted it and my Knox counter has gone up.
What do you think XDA? Just get a replacement battery?

If you have the ability, since it was dropped, I would open it and make sure connection is tight to battery and screen. Then if it still acts up, get a battery. Several people had battery issues out of the box. All it turned out to be for a few was a loose connection.
i was thinking about that but i'm afraid of voiding warranty. do i even still have warranty? due to the knox?

Well ive opened it up and tightened everything i can see and it seems to work ok for a while, when the charge gets to around 20-30%, the tablet flickers, all mobile connections are lost and 75% of the time, reboots.
So i went ahead and got a new battery. Now this was worse kinda. At random moments, like unlocking the screen, or replying to a message, or maybe just a high cpu load event, the tablet just turns off and is unable to be powered back on without first connecting it to a power supply like a wall charger or a power bank.
The time and date will be reset once its back on and ill have to wait a few minutes before the auto network time setting kicks in before i can use something like whatsapp.
Anyone got any clue what might be causing this problem? Thanks in advance, helpful xdarians.

I'm not by any means an expert or repairman of any kind, just so you know. I'm thinking maybe a loose connection at the terminals on the board the battery connects to or if they use a separate board for the battery to connect to and then to the main board it may be somewhere along in there. Maybe a loose wire going into the tab that connects to the prongs. It sure sounds like something isn't making a good connection. Sounds like a load gets put on it and it and that bad connection can't handle the load.
Might just be you're going to have to send it off...
You may be right. Sounds like a particular connection which does higher load or something. Once i put the tablet in power save mode, the symptoms never reappeared. I dont notice a drastic slowdown in the tablet either. Probably am prolonging the inevitable.

I am facing exactly same issue what you have described and am in same situation, have tripped Knox on my Tab S 8.4.
I can see that you have been able to suppress the behavior by putting it to Power Saving mode. Have you experienced flicker and reboot since then? I am planning to take it to Samsung store not sure if they will honor warranty, did you tried that?

nope, ever since the Power Saving mode solution, it hasnt flickered and rebooted yet. and my warranty was expired by that point so i didnt bring it to the shop. no noticable reduction in performance so far

I have seen this problems on 2 tablets 10.5 and 8.4 the connector where battery is connected on motherboard gets loose which causes reboots and flicker
Solution in my case was resoldering that connector again
i had the same problem, opened up my tablet, just disconnected the battery, cleaned the contacts, pushed it back, made sure its nice and snug, put it all back together and now battery doesn't drain as fast, no more flickers and reboots!
hmm. i'll have to give it a try. you think this may be something to do with condensation?
Sorry for the bump, but I'm having this issue as well on my S 8.4. Custom ROM. The thing with me is that it's not consistent. One day, it will do it a few times; others, no issues whatsoever. I'll try the suggested if it gets progressively worse.
Hey guys,
Unfortunately our home's tablet (Tab s 8.4 Wifi) has the same problem.
It never did weird whatshowever, but when I flashed a custom rom (which went perfectly smooth actually) the screen flashes and the tablet reboots sometimes.
Now it weird that this never happened before and only when I flashed a custom rom it began showing this behaviour.
I am affraid of opening this tablet, and I guess because of the custom rom there is no warranty left anymore (or can this be bypassed by some terminal trick?)
Also I question myself if this is not a software issue, and that it can be fixed with software or so?
Thanks for answering!
My Fix
Hey Guys!
I might have some surprising news to tell about this "issue".
I saw some unboxing video's and saw at what place the battery connector was placed. It was some sort of a 'push to click' system.
So what I did was the following:
I pushed the tablet at the place of the battery connector. I tried this at various places until I heard a *click*.
Now I don't have this issue anymore. Jay!
I hope this will help you too!
I started to have the same issue on a Tab Pro 12.2, presumably after the battery has lost considerable amount of its energy. Normally I remember this tablet to have a dazzling 10+ hours of usage time. Just after some serious usage time of more than 2 years this issue started, along with increasing temperature and finally reboot. From time to time Android gave a warning message about overheating. From time to time charge values drop big values at a time. From 45 to 20 or 80 to 50. Seems arbitrary. This was happening even when I was on stock, then I switched to some Android 6 stock port from some other tablet. Still the same.
I believe the battery needs replacement. (That's obvious after 18 months, I just mean blinking is related to this) Hope I can find a high quality one cause there are several garbage batteries.

Serious over heating issue

So ive had my Tmobile G4 for about 3 weeks now. Ive been using the G series since it started. I love the G4 but wow ive never had a phone with this type of heating issue.
There is not a time when the phone js not at least warm to touch. Few times a day it gets to the point where its too hot to touch at all. Forget about making a phone call way to hot to lut against face.
Im not doing muxh of anything either. Web browse etc... But its hot at idle screen off just sitting there.
Anyone have issues with heating? Multiple times its given me the over heating message and shuts off phone.
Last night for example it got to 80c.... Thats fricken hot!
Could factory reset help it? I dont know what to do at this point? Am i just having to get a replacement? As i type this from my g4 sensors showing high 60 to low 70C.
The heat is generating from the top half of the phone btw. Like at the camera it feels like.
Any suggestions or help? Thanks

Is the battery draining abnormally fast? Check the usage for play service, could need that fix
If you live in a hot area like me, such as LA, then you probably experienced phone shutting down while using phone as a GPS due to the overheat.
I've never Had that problems with all of my previous phones but I'd give few software updates for optimization.

Yeah battery is draibing very fasy. I use a battery monitor and nothing is sucking it up.
Also, i live in Arizona where it has been 110 degrees daily. Though it hasnt shut down from heat outside or when using gps yet.
It shut down with over heat warning last night in my apartment where its 67 degrees in here while i was on google.com just browsing. So im clueless right now.
I just cleared cache partition and booted to safe mode to see if it runs any better.
I can leave my phone on my table for an hour and pick it up and itll still be scorching hot doing nothing. Its literally never not hot to touch.
Yeah. That's the mytmobile app... Unchecked all the boxes in the settings. Helped me

My 1st Tmobile G4 Online Preorder had some problems mostly screen. I sent it back. I went to the store and bought one. That one was always hot as well. It was always throwing warnings at me. I had Gmaps on in my car with the AC on and only 70F out the time and it shut down on me. I called Tmobile and did some master reset etc and still was the same. I finally just went back to the store and told them to exchange it after they seen how hot it got in store. Tired to tell me I was at 15days when I went back in but I called in a few days before and asked what day was the 14th Monday or Tuesday I guess they count Purchase day as day 1 and that's what I thought but the person I talked to said no but they called Manager and they honored it. This phone finally seems to be good a few little issue's but they should get worked out soon with software we all hope. The 1st 2 phone's I had the Update Pushed to my phone the 3rd one was already on the phone so might be newer batch ? I was not happy spending over $600 on the phone with the issue's I had on those til this 3rd one which is good so far.

Then I'd say that even when it's doing nothing, it's still actually doing something, maybe just something it shouldn't be doing.
My Verizon G4 ran warm, and I was disappointed with the battery life. Different monitoring tools were unable to point me to what app (?) was causing the problem. Sometimes it would stay cooler after a reboot. Mine was never just constantly hot, however. Mine would be cool sometimes when sitting around, and then sometimes warm. Like taking it off the charger in the mornings, some days it would be cool, others it would be warm (~95F or so), when it had been just sitting there with the screen off.
Just now for example. After i replied here i out my phone on my table. I just now picked it up and it was 74 C. Scorching. Like its just gonna melt ibro a pile of G4 goo lol.
I guess ill call my store on Monday. Safe mode and clearing cache partition didnt help at all.

Are you using a case with it? I recently had overheating issues and figured out that the leather wallet case I was using was causing my G4 leather to overheat. It went as high as 112°5F But as soon as removed it it went back to normal.

Nah I have the black version normal backing not the leather version. I have the thin Tech21 case but i took it off a week ago to see if this helps.
As im typing this my phone is at 75C which is 167 degrees F! So hot!
Possible a Facorty reset could help? I really dont have many apps installed right now either. Since its relatively new ive been slowly installing apps. I started blank, didnt install anything from backups etc. The apps i do have installed are pretty basic. Nothing syncing or running. Ive been clear the recents aswell just to try. Frustrating
Have you tried turning off WiFi? I've noticed occasionally that my phone will constantly drop WiFi on my home router and reconnect a few seconds later, repeating this until I restart the router. All of that constant disconnecting and reconnecting makes it pretty hot...

Yeah its happening regardless. I turn data off when im on wifi and my wifi never loses connection, it stays constant. Though i did try a few days ago using no data or wifi and same dral, just hot.
Have you tried a factory reset? I leave my wifi on and stream music and everything. The only time it gets warm is when I Fast Charge. But I mostly wirelessly charge so its still cool.
Maybe you should exchange it.
I'm second on that doing factory reset. Seems like you have a corrupted profile or rogue app, or both.

I were having over heating problems on my G4. It were so hot at one point that my 6 year old daughter picked it up to play a game on it. The phone was that hot my daughter actually started crying cause the phone burnt her hand. This is not good. I have an awful lot of applications on my handset, over 300 so before I contacted LG I did a LG backup and reset. I restored probably half the apps what I had and a week after I haven't had a problem and the phone seems to be running as it should. The phone isn't even warm.
My theory is the G4 has 64bit processors. The snapdragon 810 processors were known for over heating and the G4 uses the snapdragon 808 processors for this reason. The 64bit processors deal with twice the data at the same time to the old 32bit processors and this contributes to them getting too hot. I feel that a few tweaks by developers and updates from LG is what's needed to combat the over heating. Time is our friend here and a bit of common sense. When you install a new app and overheating occurs then just remove the problem app. I always see how the app affects the handset now for over heating problems.
The 64bit processors in the G4 are new and need to have some updates to combat the overheating I feel. I recommend a system restore, debloating and only using the apps what you need.
I remember when pc's went from 32bit to 64bit processors. There were processors burning out, melting, water cooling became popular and bigger fans to combat the over heating. In time it sorted itself out so I feel this is the case for the G4 and other new handsets running 64bit processors.
Hope this helps.
Did anyone try unchecking the boxes in the my T-Mobile app? My phone went from 50% to %5 in less than 30 mins running crazy hot. You could also try uninstalling the app updates, or using the debloater tool on xda to disable it.

Same here, although not so hot that it "burns". iPhone 6 got warm but never so hot - software improvements should help combat this over time. +1 on the debloat tool.
One may argue the dead air via removable back cover can act as an insulator vs a compact design. Maybe just get an Otterbox/Thick case so you can't notice the heat as much? Could possibly lower battery lifespan though.
I've had my AT&T G4 for a little over a week. The first couple days the battery life was horrendous so I did a factory reset. The battery life improved greatly however that's when I noticed the top half of my screen getting unbearably hot. Another factory reset didn't solve the issue. So I talked with an AT&T Rep and am taking mine in for a replacement now. Hopefully will resolve this issue. Will update.

While in the Woods..

Hey guys,
I currently own a Samsung Galaxy S9 and previously owned a Huawei Nexus 6p, both devices, while in the woods, behave very strangely. Since I don't own the 6p anymore, I'm only going to speak of the S9, which is brand new and in brand new condition. But this used to happen on my 6p as well!
A good 75% of the time, when I take my phone out of my pocket, it will be at the boot pattern lock screen. The screen will be on and the battery will have drained substantially. Somehow, the device is rebooting while in my pocket. This ONLY happens when I go camping in the woods here in Ontario. NEVER happens any other time. And it won't happen just once or twice. It'll happen a dozen times over the course of a day easily. My battery, while out in the woods, never lasts more than a day, even though I almost never use it.
Yes. I'm positive I'm not pocket rebooting. I'll move the phone into my cargo pocket, which has TONS of room. Same thing. I'm running stock Samsung, no root, nothing. The stock experience so far has been very smooth and stable. I've had no reboots, very little lags, etc. I step into the woods, BAM, starts acting a fool.
I have a Garmin watch connected via BT, but the watch is ALWAYS connected. NEVER had any issues with the Garmin device. Thought I'd mention this, since it's the only device I have connected to my S9.
Anyone else experiencing this? Or do I sound totally crazy here?? It bothers me because I don't want to go camping with a power bank. I'm often resorted to turning the device off completely and leaving it in my backpack, which isn't ideal.

It'll happen a dozen times over the course of a day easily. My battery, while out in the woods, never lasts more than a day, even though I almost never use it.
Yes. I'm positive I'm not pocket rebooting. I'll move the phone into my cargo pocket, which has TONS of room. Same thing. I'm running stock Samsung, no root, nothing. The stock experience so far has been very smooth and stable. I've had no reboots, very little lags, etc. I step into the woods, BAM, starts acting a fool.
I have a Garmin watch connected via BT, but the watch is ALWAYS connected. NEVER had any issues with the Garmin device. Thought I'd mention this, since it's the only device I have connected to my S9.
Anyone else experiencing this? Or do I sound totally crazy here?? It bothers me because I don't want to go camping with a power bank. I'm often resorted to turning the device off completely and leaving it in my backpack, which isn't ideal.

Check if Settings > Display > Navigation Bar > Hard Press Home Button & Unlock With Home Button are disabled, otherwise it is very easy to turn the screen on when you pull the phone out of your pocket, was happening to me for a while until I realised what was happening
Battery drain could be coming from low carrier signal forcing the phone to search for a signal a lot more than usual
I'd stay out of those woods! ?

Those settings were actually one of the first things I disabled on my S9. SUPER ANNOYING, but those aren't the causes for my strange behavior. I've experienced this same issue with all those disabled, as well as on a completely different device that doesn't even have those settings.

Really?? I did not realize this was a thing. Something to keep my eye out. Most places I go camping, even though deep in the woods, still has cellular reception, but usually not LTE, only 3G or no-G even some times. Are you able to enlighten me on when the S9 drains the most when it comes to it's carrier signal? I just want to know how to set my phone next time I go into the woods for best troubleshooting.
Thanks for the reply!

Last I checked, they are probe-free woods. My phone is probably the one getting the probe.

I generally have 4G most places I am so I can't help there, but I would try setting the preferred connection type to whatever you seem to get in the woods the most, so if it drops to H+ or E or whatever you get when 3/4G isn't available, set it to 2G or whatever the lowest available is in connection settings, could be that searching for a 3/4G signal constantly is causing that drain so telling it not to even look for one could help, but also could be that this radio type is causing that drain itself, maybe 3/4G signals are a lot less power hungry regardless of whether or not the phone is set manually to them or not
You could test it in the house now, set it to 2G and do a battery drain test vs 3/4G you usually have, if there is no extra drain in the house, there should be no extra drain in the woods, but if there is then 2G and lesser obviously uses a lot more power

This guy gets it. You have been warned, lol. If you have a logcat I'm sure someone would be able to identify the problem.

Haha!
Logcat is a good idea. I think the next time I'm out there, I'll pull one and we'll see what's what.
Should be going back into the woods real soon. Blair Witch be damned.
