LG G3 random reboots and possible CPU overheat. - G3 Q&A, Help & Troubleshooting

Hello,
New to the forums, I registered today seeking help for a VERY annoying issue. My G3, which I bought brand new around 2 months ago, after some weeks of usage started to reboot itself at random times. Now, I am noobish when it comes to android, so I have no clue why that occured. After some search, I wonder it may have been a faulty battery (seemed to be the case with many) or a memory leak. I monitored the RAM and the CPU, the RAM is in about 80% most of the time. The CPU usage is very low, but it suffers from slight overheating (around 70 celsius sometimes). The phone reboots at random times. Its often that android warns me that "settings have stopped". I dont know what to make from that. Anyway... I hope some of you tech freaks will be helpful.
Thanks.

I had this issue too...So i got new Battery and it was much much better...Then it occured again but like 1x-2x per month so it's not bad...And few days ago i've got new Android Marshmallow (Android 6) and it looks good to me....
Even temperature is betterr than on Lollipop (Android 5)

These are common issues on the g3 best thing to do is root it and install a custom rom most have adressed these issues

What kind of rom??? I haven't rooted it.

[Q] G3 still worth it with overheating and other bugs?

Hello guys,
I'm thinking of buying the LG g3 which for me is the best phone right now. However, I have seen it has some bugs regarding overheating, WiFi drop, bad battery life etc.. Do you think it is still worth it or should I go for a Z2 which has the same price in my country (Spain). Regarding the overheating issue, a lot of people say they have it and a lot of people say they don't... Is This just chance or is it linked to a specific model and version?
Thanks

Watch that and make your own mind up - this is the opinion of Pocketnow - 3 months after launch.

As the overheating, since I upgraded to v10L firmware, overheating issues it completely gone for me, even after 40 minutes of playing Real Racing 3 on max detail mod or Dead Trigger 2 for about half an hour. It still heats just like every other device ( HTC, Samsung or Sony) but it doesn't get to extreme temperatures which turn off your phone automatically. What are those other bugs you are refering to?

I have my LG G3 for 2 months now and I never experienced any random reboot,except for 2 times when it said the reason was extreme temperature, but that got away after updating firmware and never happened again. But it was only when I had first firmware. I also use ART as runtime which is considered to be buggier and more "app crashy" than Dalvik, but I never got any crash or random reboot.. Usage of unoptimized apps can random reboot any phone. As for LG software, LG's apps and the most common and most widely used apps work perfectly without any hiccup. You should never experience any error, crash or random reboot. At least I didn't. Always try to use trusted and well optimized apps if you want the best experience. Also don't install any battery or RAM cleaning apps, that **** just slows down your phone and drain your battery rapidly. It depends on you if your phone will random reboot or not. It's not just LG thing, it also concerns HTC, Sony, Samsung or any other manufacturer. You can ask my sister, she installed few cleaners, RAM boosters, 1 optimizer and 2 battery boosters on new Nexus 7 which should be most stable Android experience, but her battery life got worse and she does often get random reboot. So treat your phone well and it won't random reboot anytime

[Q] [Lollipop] Temperature and Battery 2nd Gen

Hello guys, My name is Icaro and I visit this forum since a few years a go, I first met you guys when I had an Motorola Defy MB525 (Yeah the Legendary Defy! ) and since this I've been visiting here like an ghost so many times without login, in my account, just seeing what was happening to the devices. Well, the years was passing and I've upgraded the Defy to an Moto G XT1033 and put my hands on a brand new Nexus 7 2nd Gen.
Since Google I/O I was waiting Lollipop, just because I've falling in love with the Design characteristics,I first guess that the update has been AWESOME, but now the official was getting some problems that Developer previews didn't had, the first ones because the LPX13D had similar issues.
I'm getting some issues, you guys are getting the same or others like these? Let me know!
First Update
System Image: 5.0 LPX21P
Flash Method: ADB Fastboot Google's Flash-all Script ​
The first issue
The device seems to be more hot when the screen is just on, some times in idle or in occasionally use, and when the device is playing some music... Think that this was caused by the ART runtime but I don't know if It's really this...​
The second issue
The battery it's having an huge drain, the device stopped to work all day to work now to half a day... And this is pretty scary, since you guys know that KK update was holding the device all the day by 24hrs in moderated use, finishing the day with more less 40% of the battery.
Second Update​System Image: 4.4.4 KTU84P + 5.0 LPX21P​Flash Method: ADB Sideload (Forced OTA)​
First Issue not Fixed... The Device continues to get abnormal temperatures without an "powerfull" usage...
Second issues seems to be fixed, battery now drops 1% every 10 minutes approximate.
If you want a guess, It's better you use ADB sideload to do an forced OTA update.
I think that Lollipop AOSP Image LPX21P has some battery drops/drains that the OTA don't have.
Are you getting this some issues?​

Lolipop Memory Issues Poll: T-700

I can't make a poll thread from Tapatalk I guess, so I'm just looking for comments.
I got the notice to download the 5.0 update today. I'm hesitant to do so due to the many issues reported for other devices. I have a 2012 Nexus 7 that had serious issues until google released the update to 5.1. I do not want to repeat that experience (it took months of waiting).
I have the US version of the 8.4 inch Tab S.
For those of you who have installed the update, have you noticed any issues, specifically memory related? I am not looking for opinions about whether you like Lolipop, so I would request only comments regarding what differences, if any, you notice in how the tablet is running after the update.
Signature edited to appease the OCD's
I have the U.S. Tab S 8.4 WiFi and updated to Lollipop. It's running smooth and snappier than KitKat. I haven't noticed any memory issues with it. Battery life is good so far, on par with how it was under KitKat for me.
Thanks. I would hope samsung would make certain the update would not cause this problem, but you never know! It's pretty well documented at this point.
Signature edited to appease the OCD's
Mine reboots constantly. Garbage.
So we've got one person who updated without problems and one who is having reboots. Who else has taken the update and what experience did you have?
Also, does anybody know what the options are to downgrade if it turns out that 5.0 does have a lot of problems?
No problems on my S 8.4. I also have Touchwiz Lollipop (5.0.1) on my Galaxy S4 with no problems. I read somewhere that the memory leak issue was only a problem on AOSP builds, not OEM (Samsung, HTC, etc) releases. I don't know if that's true. I'm 100% happy with Lollipop on my S 8.4.
all good here. like the changes from lollipop and touchwiz doesn't seem as bad from what people make it out to be. wish you could uninstall some apps tho.
Originally, I had a 2012 Nexus 7. After installing 5.0, it became unusable. I tried almost everything I read to no avail. Actually, it had started slowing down and having and having random app crashes b4 that, but it got much worse after installing 5.0
I gave up on it and bought the Tab 8.4, which I'm loving. Several weeks later, I went back to the Nexus 7 and used Wug's Toolkit to wipe and install 5.1.1. That has actually seemed to fix my issues with that tablet. Now I'm thinking perhaps I didn't need to get the Samsung, but oh well. I like the larger screen (I always said tablets should come in 8 inches, not 7), the rear camera, and the responsiveness. I'm keeping it!
Because of my negative experience with 5.0, I was hesitant to install this update. However, I installed it yesterday and so far (after 24 hours), it seems to be fine. I like being able to see my notifications on the lock screen again. It still appears to be snappy. It has not been long enough for me to judge battery time yet. So far it looks good.

Why not root it? Then you could uninstall anything you want to.
After the update it was all good with my tablet, smoth and fast.
Now it's getting worse, Nova launcher is always crashing, sometimes it reboots by itself, lag came back and some apps freeze...
I hope that Samsung release a new update.
Does the OTA update work with root installed?, I have the T800.

There's some apps/games that don't work on rooted devices so I had to keep it stock.
I updated OTA to 5.02 and had no problems. Tab is as quick as before.
I noticed a slight increase in ram usage (from around 1400 to 1700 mb) Now after medium use it hangs around 2GB. Until now I didnt see a problem with that.
Battery usage seems a little better (but thats alway subjective) I had a problem that the charging percentage went from 85% to 100 % in a couple a minutes. Now, connected to USB it charges 1% every 5-6 minutes. and it does so also from 85%-100% There are some slight things I dont like about 5 but again thats to subjective.
One of the things I loke is that its now possible to switch of notifications per app. I hated apps that which me "Goodbye and hope to see you soon, sleep well, say hello to your wife"

So, if I understand, you're saying that you're seeing higher RAM usage with 5.0, but it hasn't caused any problem? Also, for me charging on KitKat is very fast. Does your tab charge as fast on Lollipop as it did before?

that is correct,. i see higher ram usage but no ill effect
on usb it charges approx the same kitkat and lollipop 1.% every 5 6 minutes i hardly ever charge on charger but that is a lot quicker
After three days I agree with HANSB57. However, my opinion is completely subjective. I have not measured anything.

I also experience frequent reboots using certain apps or even general Web browsing. I just restored to factory default so I will see if things improve. So far I've already experienced one crash after doing this. Hopefully a follow up update is in the works.

Very disappointed to buy a HTC 10, and some questions

Good afternoon to all, I hope you can help me with this situation.
I have 20 days with the HTC 10, and I can not be more disappointed of its performance, and coming from a galaxy s6, but we go by parts.
1- the phone, it gets very hot, very fast, especially after updating to nougat 7, I mean, with 15 20 minutes of surfing on the web, it reaches temperatures between 40-44 C ° (104-111 F °) , At this temperature it is uncomfortable to hold. Is this normal ??
Taking into account that I do not play, I only watch videos, I listen to music and web, because I just did a hard reset, which brings us to point 2.
2 - It is the first time, I update an android version, and a big error appears, once updated to android 7, the keyboard stopped working (swiftkey), so I could not access it because it was protected By password, and the keyboard in the start section, never displayed. I had to do a hard reset with only 15 days of use, seriously WTF!
3- Due to the warm up, the battery life is quite poor (between 3.5 and 4 hours of screen, no play, or take pictures all day, turning off mobile data at times and wifi, is this battery drain normal?
The battery come to exhaust quickly, especially when the phone is very hot, when restarting the phone, it eats 3-5% of battery every time.
When taking photos the same, the battery drops very quickly.
4- I normally play on a PC at 60 fps, the phone when playing video on youtube, has a slight lag or "stuttering", this jumps out at me very easily, although there are people who do not see it at all, I do by The same as I mentioned earlier.
When playing video youtube on the phone, the camera movements are not smooth, there are micro-cuts to the FPS, and it is very annoying.
5- before upgrading to android 7, just install a game, "realm defense, hero legends", a very popular game on android, and felt like it was under 30fps all the time, my previous galaxy s6 handled this very smooth,
6- Points 4 and 5 are solved by activating the "high performance" option in the menu of developers, the lag in the videos disappears completely, and the games feel very good, but with the consequent increase in battery usage and Temperature, seriously WTF again.
The phone according to CPUZ has a load of 15-35% all the time without loading any application, this is normal in andrid 7 ??
The phone is in stock status, with the update of the operator, I have no ROM installed, and I have no idea how to do it, because I would not like to lose the warranty.
Any recommendations to this situation ??
THANKS and excuse my bad English.
May want to ask for a replacement. None of the issues you mentioned here and I have been using this phone for almost a year.
No these are not normal. Obviously something is running around causing the CPU usage and eating the battery. Given how many problems you're having I would do a factory reset, see how it goes without installing any apps. If things get better that'll help your pinpoint the troublesome app(s). If not, a replacement is in order.

I'll second that, although I've only used mine for about six months. I do admit that running Android 6 the phone did seem to get hotter than it does with Android 7.
That being said, when I'm running a game battery life does suck, and it does get warm. I think I'm about 5 to 6 hours of screen on time, but I'm also bone stock with a bunch of extra apps in the background.

Thank you friend, I am interested to know more about your experience with the phone, why you only had 6 months?
Could you fix some problem that he gave you?
Greetings.
I have HTC 10 for one year and several days, never had those issues.
I admit HTC storage r&w speed is slower than S6 because of emmc5.1, but mine is smooth enough.
I also recognized the battery life is shorter on Android 7.0, but it's a general issue for phones upgraded to this version of Android...Not just HTC10, Sony, Samsung etc also has this problem.
As for SwiftKey stopped working, I have no such an issue, in fact I'm a mod of SwiftKey.
At last for the temperature, mine gets 38 °C while fast charging; 42°C is max while playing heavy games.

Mine gets 40°C Without doing anything, and playing reaches 44-45 °
And it seems ridiculous, that when doing this app can not with the 60fps, for a little ball in 2D.

Again, it reaches almost 60 FPS, activating the high performance mode.
Thanks for sharing your experience.

Sorry, I should clarify...
I've had the phone for about 7-8 months now (longer than I originally thought, got it back in September of last year...) and got the update to nougat about 4 months ago.
When the phone was running marshmallow, it would get warm while working on tasks that aren't CPU/GPU intensive. With the update to nougat, it definitely helped with the heat production. That's not to say it doesn't get warm... If I'm playing Rayman Classic on full brightness, that phone gets really REALLY warm. But when playing Deus Ex - The Fall, even on high brightness, it doesn't get uncomfortably warm like when playing Rayman. Also, basic tasks don't overheat the phone like they would on MM.
I should note that I typically leave power saver turned on as well. I've found it doesn't affect performance noticeably for myself. I've also had Boost+ optimise all foreground apps from the overheating nightmare on MM, and I hadn't bothered to turn it off... These could play into the heat production of my phone as well...
My time with this awesome phone has been so short due to my contract with my former service provider...
I think most of your issues will get resolved after installing Custom Rom. Infact I am in similar situation like you. I can't root my phone due to warranty. As i know for fact that in my country HTC charge huge amount of money even for small issue. After spending that much money on repair, there is no guarantee that phone will work fine cause engineers are not capable enough, maybe cost cutting by HTC. Meanwhile i would suggest select SRGB instead of Vivid display, it will surely reduce heating problem to some extent.

Question Phone Overheating - Is There a Fix?

I'm on Android 13 and was hoping this would sort out the overheating problem I had with Android 12 (I read in a few places that it would), but it did not. The phone gets very warm when charging, and hot when streaming video, and just generally through simple use, nothing particularly demanding. I haven't rooted this phone because I did not see the need, but I would consider it if it was the only way to fix the problem. Is anyone experiencing the same, and does anyone have a solution?
I could be wrong but generally speaking in my experience, going from one major upgrade to another the phone works a bit harder to re-train itself to your use patterns. I just did my upgrade yesterday and experienced some slight to moderate heat as well. I also noticed that battery is draining a bit faster which I think again is part of the process. I'm going to give it a week or so and if I'm right it should improve.
I'm biased because I've had my Pixel 6 Pro rooted (and updated every month) since last November, and I also use Kirisakura custom kernel with its companion apps and currently have the one app set to the maximum battery savings.
So I can't really compare to 100% stock unrooted with the stock kernel, as I'm only briefly on the stock unrooted kernel each month after I manually flash the latest update.
Several others have commented, and I've experienced too, that with Android 13, we've no longer experienced as severe higher temperatures when charging. I don't remember if the others were rooted and using the same custom kernel, or if these were general Android 13 comments, so your mileage may vary. Sorry I can't give you any more concrete information.
Good luck!
Granted this is for my 4a5g but I wouln't be suprised if/when I get a 6 that its battery performance would be less than stellar after a good days use of phone and/or screen and radio/network. i.e. stock. Before I went to Lineage on my 4a5g I think my battery would cut a good 30-50+ percent each day. I put lineage on it and I poop you not, can go from a 75% to around 20% in about 5-6+ days. I tend to have my screen brightness around a little less than 1/4th on the slider bar.
When I had an HTC M8, after around 2 or so years (this was around 2016/7 or so. got phone oct '14) on the stock firmware the phone couln't keep it on for more than a day. Ran ViperRom for a bit then switched to cm/lineage and that stretched my usability of the phone another 5 years. It got to the point where the phone would shut off when it got to around %50 charge and go ding dong and turn off--without pluggin it in I had about 8 hours run time on it. My battery was beyond gone and no way would I have gotten that usability on the stock rom.
So, to answer your question, yes, trying different roms and kernels (rooting) could be to your advantage to prolong the life and performance of your phone.
Even if you choose to run the stock OS, with root, you could disble any bloat running in background. Kill any programs/services leeching CPU (and hence battery) cycles. You could definately make it run more efficient for YOU. Maybe not for the next guy who needs his facebook, twitter, ticktok apis and stuff loaded and at the ready. Everyone is different. But they tend to make the phones (they think) for everyone. in mind and as a result, device performance and lifespan become affected.
I definitely have heating issues and this is on a warranty exchange. The 2 previous P6Ps had all the same issues as this current device.
My phone was hot on A12 (41/45°) and since i clean flashed A13 and wiped it is cold (32/35°) for the same usage.
Greetings.
Good topic.
I have bought this phone a day before. I'm facing device heating even under simple tasks like scrolling messengers, browsing etc.
Previously I had OnePlus 7 Pro (Snapdragon 855), that one was cold all time except while charging or playing games.
However, Pixel looks warm or even hot even upon light using.
I'm a bit confused about that.
Is it a common problem of this device? Or probably exactly my device is affected?
I haven't faced overheating or alerts about that, however, it feels hot for my hands that got used to feel a cold phone while low load.
Currently, I have about 37-38 degrees while browsing on XDA and writing this post.
Just wondering that digits you have?
I did a warranty exchange on my P6P for a different issue and I'm glad I did. My replacement device has much better thermals than my original. My original one would get quite hot while charging and restoring apps and was almost uncomfortable to hold and to the touch. Could always try a warranty exchange and see if the replacement device is better for you. Also, Kiri kernel has been reported to help with the thermals. I've seen several reports of users commenting that their device runs cooler. Good luck!
I had heating issues and battery issues when I first received my P6P. Once I got it out of the box, I set it up and restored backups, rooted it, updated to android 13 without wiping, rooted again, and then flashed the Kirisakura kernel. I decided to try and flash android 13 again but keeping the -w flag to wipe userdata and didnt restore my backups and I've had amazing battery life and no overheating. If you haven't yet, try doing a factory reset. As simple as it sounds it may very well help
My fully stock P6P (on A12) gave an overheat warning yesterday while we were having a day out, it was only 22°C although we were in and out of the sun as the clouds rolled by but the phone was showing 46°C after being sat in my pocket.
I think Google have released the worlds hottest running phone, i have never owned a phone that heats up so much and so fast.

Thing is I have never experienced overheating on any phone (that i have owned) in UK before, using an Exynos as the basis of Tensor and then whacking an extra big core in it was a pretty bad idea unless you live in a fridge.
