what are the main issues and questions about the lg g3?

What are the main issues of the lg g3 (planning to buy one)..
Does it have the screen issue like the g2? https://www.youtube.com/watch?v=Fd5BTKpViUk
is there a fix for the overheating and shutdown issues?
how is performance in gaming?
is it possible to reduce the resolution to 1080p to save battery and gain performance (and maybe prevent overheating)?

Read through The G3 threads you will know the answer to all of these.
You cant reduce resolution.
Gaming is decent
I have had no such overheating since 10H update and no shutdown issues ever.

OK the. Do other users also have temperature and shutdown issue fixed with the lg update?

Never had shutdown or overheating no matter what firmware. It's abit laggy tho but way better with art etc.

I guess you guys are not heavy users? cuz I read a lot of users have overheating issues with message prompting them to decrease brightness as it is overtheating and may shutdown (what the heck? ... LG really lost it on that one... Do you really expect to get that kind of message on a flagship pricey phone??). LG seems to be making great phones but each time there's a deal breaker. (screen issues with LG G2 and now overheating/performance issues on the LG G3)... I hope they get it right with the G4.

Did antutu x benchmarks, 3 times in a row with 90% brightness without auto with an ambient temp of 30c. I actually can't remember if my score was lower last time (because of throttling), gonna check it when I receive my phone again.
No message about high temp etc tho.

ok you are probably not a heavy user.

I am a very heavy user. No issues. People need to understand a simple factory reset and installing the latest update helps. When i first got it i performed a factory reset and installed thr latest update manually so i never really had time to see if it had issues on previous firmware . although i did run a benchmark when i got it it got really hot. But i did the same after the update it just got a little warm nothing to worry about.

ok. I want to know if other users have these issues solved with the updates like you.

Zero issues, apart from the screen sharpening and abysmal battery life when the screen is on

abysmal battery life?
No one is experiencing this lg g2 issue on the G3 right?:

nice video showing that how lg g3 compares to the cat 6 version and the galaxy s5 prime

Sometimes the phone become hot specially when the phone is charging and I'm texting and browsing 'usually in a dark room so the brightness is 0%'
And yes my phone brightness decreased to 90% automatically and sometimes 80% due to overheating
Lg g2 was faster than g3 and you can see it when you use it for a long time
Overall. Go for it its awesome device

[FIXED] Amazing battery discharge

Hello,
Since I updated to MM, lot of things went wrong. Few days ago I got 3-5 hours SoT, and now it is really bad.. this morning it shows 1 hour estimated left and the phone is hot.
Instled GSam, will post screenshots later today.
What's the problem?

did you do a factory reset after updating to MM ?

I have noticed a similar effect on mine, but not so drastic. I used to get over 4hrs+ Screen Time On using Lollipop. Now 3 hours or less. Factory resetting didn't help.

Yes, everything wiped, all reset.. so no old data. MM is not as good as LP :/

Thank you for letting us know. Was thinking of installing MM but I value battery life over everything else.
..Sent from an XDA modified LG G4 on Verizon..

Yeah mate, np.. keep with Lollipop, MM is really worst. I'm using my G4 for about 20 minutes and already lost 10%. Battery life is incredibly low
I'm seriously thinking about downgrading to LP.

I tried going back to LP, but this didn't work for me. I thought I has bricked my G4, but thankfully LG Bridge managed to restore to factory settings.
As well as draining the battery twice as quickly (at least twice as quickly), I can now no longer pair my G4 with my car (so I can take calls by pressing a button on the steering wheel). Bluetooth just keeps crashing on the G4.
I wish I could go back to LP easily. After my last experience trying to install LP KDZ, I'm not confident enough to try it again.

Which tool/method did you use?
On the main MM battery life topic, it seems that the downgrade is successful through LGUP soft.

Am on same boat as you guys. Now, I updated my wifes G3 with MM and the battery time is far better than on Lollipop or on my G4! Go figure[emoji15]

Ok so, I found the okayest fix: if you use custom ROM (like Genisys), flash the stock kernel, it's much butter.
At the moment, no more battery drain/random reboot/overheating . :good:
Seems that SUPEREX kernel is faulty.
https://www.androidfilehost.com/?fid=24269982087005245

I found that the battery is almost 50% on MM compared to LL. From MM i often set the "economy mode" (or what's the name) and turn off wifi and bluetooth wehn I don't use it.
Using it with LG what is almost impossible, the watch drain the battery too much.
Luckili:
1- 20C is out, we have just to whait, I heard that on 20A battery has not that huge battery problem, so maybe they found a bug in the 20B
2-you can carry spare cheap batteries with you, I have always one in my jean poket...

1- I'm going to update to 20c ASAP (downloading right now..)
2- the issue was related to custom kernel SUPEREX integrated in Genisys ROM, flashing stock fixed it
3- I have an extra LG battery + charging cradle and a thin power bank (10000 mAh)

My LG G3 is overheating and crashing

Hi,
New to my LG G3 and just had a thermal runaway where the phone crashed and rebooted, and CPU-Z showed most of the sensors at 95Centigrade. After the phone sat for a bit, it's back to 50 C. I think this has been happening fairly often, maybe once a day, in this case it happened while charging wirelessly, and yesterday while talking on the phone.
Running Android 4.4.2 the 12B version. Rooted.
Is there something I can do to fix this? I really don't like having an unstable phone.

try clean flash rom using lg flashtool.if also not solved then try changing the battery.

don't want to redo the rom, too much work. How would changing the battery make a difference?

Overheating too on BareCee - Sprint LG G3

I've been having similar issues. Just installed CPU-z but it's not doing it right now. My phone has overheated so bad a couple of times that the screen starts flashing on/off (screen backlight stays on...image flashes) and then after a few flashes, it reverts to stock background and keeps flashing. I have to pull battery to get it to quit. Once it's back on I still have the stock wallpaper and have to change it back. It's still there....dunno what's going on! Phone almost always seems hot in shirt pocket anymore.

well you do know that phone says high temp and will shutdown only when battery temp gets over 50 celcius so battery temp is also important here.many users who faced overheating prob got their prob fixed by changing the battery ao i thought u could have had the same prob so i suggest u that.try it.who knows it could work.or if u just bought ur phone then go replace it with another one.

Overheating OnePlus 3 while charging.

Hey people.
I own the OnePlus 3 and its is on a custom ROM Named Experience OS based on OB 17.
Its running on the kernel provided by the ROM and firmware is also stock as I use TWRP from Blu_spark v 33.
Now the problem is when I am charging the device it heats up abnormally high note higher than 46 degrees.
And also I get bad standby time with only upto 4 and a half hour Run time between charges.
I have noticed high drainage from Android System.
I charge only upto 80℅.
Tell me where I am wrong.
Do I need to visit the service center..??
If you require additional information do tell me.

Try another ROM or kernal. I think sultan's ROM has better battery experice and less heat issues. Try to switch to Sultan's.

Something isn't right since dash is meant to take the heat away from the device while it's charging
Are you using the phone at the same time? Also check your app usage maybe a rouge app is keeping it away while charging and causing the heat

+1 i too face the heating issue while the phone is charging. I had a strange incident as well: When i visited my parent's house last week, i received a phone call while it was getting charged and since it was from a family person i told my father to receive it in my place as he was standing near the phone. As soon he touched the phone to his ears he told, "it's is very son".
I have been facing this since last couple of months when i used to have stock oos. Then unlocked bootloader and started triying different roms. But the heating problemus still there and instead i got addicted to installing roms every week?

Well can you provide us some data atleast? It's not normal that you have to charge your phone every few hours. This means something is draining your phone most likly an user app.. Have you tried a full clean install / factory reset with the unbrick tool (method). With 46 degree you mean Battery temp or whatever? What is your surrounding temperature?

same problem , even i'm charging my op3 from a normal charger. device temp. gets upto 42-43 C .. i live in delhi, india and its too hot here.
and one more thing that only 50 minutes takes my fon to get fully charged ,if i charge my op3 from dash charger . i dont think its good !! high temp. is not good for Li batteries
every thing stock except twrp recovery !! tried many roms but oxygen is better out of those !!

Well I will be glad to provide you data...
But what data do you want..??
And what should I use to give you data.
46 is the battery temperature.
And it's hot around my place at about 41 degree Celsius.
I haven't used the full unbrick tool yet.
Is it really required as I have to backup first XD

As soon as I use my phone the phone starts cooling down.
But as soon as I set it down it heats up again.
Tried checking for rouge app found Instagram stopped it but still no effect.
I even used the fix zip from the dev behind Experience OS.

Well you see. When you lay down your phone it will go into deep sleep. Deep sleep doesn't use alot of power which means your device won't heat up at all. In your case it does, as you describe you have only 4.5hr of standby which means something is draining your phone drastically. Can you provide some screen shots of your battery stats? Post as many different screen shots as you can. Also BetterBatteryStats is a really good app you can find the free version on XDA.

This was asked in the ExperienceOS thread too.
You have a runaway process on your phone. This will use 20-30% CPU on all cores all the time, more or less. Use an app that can check the KERNEL log like 3C Toolbox and you'll find that the heat is due to excessive logging (like several lines every second) from the same process. One of the more common issues is the kernel not able to get write permission for the pm-service to thr IPC Router. THis is solved by setting SElinux PERMISSIVE until the kernel can write to it.
This will make your phone charge slower, get hotter while doing it and give you lower SOT.
Usually this is due to using Magisk, since Magisk has issues with the sepolicy and needs to set SElinux to permissive. If SElinux is Enforcing (as it SHOULD be to protect your phone) the above issue will arise.
If you're using SuperSU then Jamal issued a FIX for this as he made an error in the init.d config for SuperSU 2.82. Basically the two issues are identical as far as the end user is concerned.
All this can be found in the Experience thread where you asked the same question and did not read the 10 posts right above your question.

Question RedMagic 6S Pro EU V3.18 charging issue

So, i was on V3.15
I got update notification of V3.18 (3.7gb?)
I clicked.
My phone battery was behaving normal, calibrated and charge current speed 5200mAh.
I upgraded to V3.18 and booom, charge current shows always half of the value.
But it charges still 5200mAh but device thinks the input current is 2500-2600mAh.
My phone is EU variant. 16/256 Ghost Edition.
I downgraded to V3.15 (yes i lost data) and problem solved. I upgraded again to V3.18 and hello, problem is back!
This causes battery to be miscalibrated.
For over a week using this update and it still persists, it did not settle down.
So now when my battery hits 18% and i charge and it hits 56%, then its not 56% but in fact, its ~80%.
Charging while phone is fully shutdown is same too. It seems like the kernel is giving false info to device. So when phone system reads 2600mAh it moves percentage by that. So when this happens it thinks it charges alow and raises percentage slow accordingly too but in fact it still charges full speed.
Anyone else experiencing this issue? Using original cable and charge adapter.
Been sending video recordings/screenshots and 8min long of video of me talking/shutting down system/rebooting but the customer service denies to admit they messed up V3.18 charging parameters. They refuse.
So tell me. Who else is experiencing this issue?
It only happens on newest OS update (NX669S_EUCommon_V3.18).
So please, if you experience same issue, write it down here and contact customer service and give them link to this thread.
Raise awareness. I fresh installed V3.18 and it still happens! Wiped data, still happens!
Not normal!
Been using this update over a week with no luck.

Greetings, I am in the exact same situation like you with the latest EU update. Just created my account to post here, since I was browsing around the web searching for eventual fix for this issue. Sadly, I am unable to downgrade to the previous version and this is driving me crazy.
Can you suggest me a way to downgrade? (there is no factory reset option, nor wiping partition in boot mode works)

You cant downgrade, if you do you will lose all data on phone with downgraded version.
The customer support i exchanged 15emails or so and they simply dont admit its their mistake. They just fool with me.
My belief is they intentionally try to ruin our battery to go for the new redmagic 7 device.
They even "overcharge" our phone. My phone alerted me at 74% (overvoltage battery charge stops). Voltage on battery raised up to 4.5voltage because battery charges still fast at 95-99% even tho phone thinks its at 74%.
But no, this Nubia company denies to admit their mistake with my proofs and tests.
Their technical team doesnt even check.
I mean they just need to put this update in their device and then charge from ~20% to 100% and they will see it.
We need more people gathering here up and to make our voice be heard. Come on guys everyone please stand up!

3.15 is the previous one we had before this bug arised.
I flashed 3.15 lost all data, then upgraded problem came back at 3.18.
But on 3.15 there isnt any.

Posted to their support with a link to the thread as well, we will search our rights if this is intentional with the release of RM7...

I also noticed, the cpu 4 main cores get stuck at 100% sometimes (for 20min or 1-2hours) causing huge heat build-up and extra high battery usage.
Sometimes it fixes itself and then quickly comes again stuck at 100%.
Only way to fix it is by rebooting phone.
Really sucks. When this happens, and you charge phone and play with charge separation, the phone goes very high temperature.
This is gaming phone? With problems?
Their kernel is bad. Their developers just DONT put effort. they cant release a simple normal clean kernel... I swear, if they dont fix these issues i will for sure go back to OnePlus as my next device, i had no such issue....

This stuck cpu issue been since initial release for months.
Sometimes dont u notice battery heats alot way more than before while doing same thing?
At times its 37c and then at times hits 40c.
Fun thing is when i plug charger it suddenly shows my battery is fallin from 39c to 35c.
Zzz this company and device, probably my first and last redmagic device.
Big regret...

I have noticed some spikes in my battery indeed, just didn't do deep digging as you did. I will definitely pay closer attention to this strange behavior from now on ... starting to get even more worried now

It wasnt like this before.

We have to wait.
Im regularly checking manually update through the app.
I noticed something.
Sometimes i see CPU is very aggresively piking to 100% the first 0-3 cores (4 cores).
Its the small cores maxing to 100% frequency very often.
But at other times it doesnt and i noticed. When it doesnt spike to 100% alot, the phone is battery friendly and doesnt heat alot even during charge, but at random moment this gets triggered and cpu becomes super aggresive for NO REASON!
This is SUPER frustrating!
Very poorly optimized phone, i will definitely not buy a RedMagic phone ever again.
My next device simply OnePlus back.
Im VERY disappointed in RedMagic... Gaming phone? Really?
Nice joke.

The video fixes the stuck cpu parameters 80% of time.
It seems like an issue lying down in the phone OS.
RedMagic Gaming phone? Hah! CONSUMER NEEDS TO POINT THESE BASIC ISSUES? What is this
Even a 200$ phone doesnt have such issues.
The video is proof of the issue being unnecesarily running 4 cores at full peak and load.
Causing unnecesary heat buildup and battery drain.
