[Q] G2 (d802) overheating, custom ROMs - G2 Q&A, Help & Troubleshooting

Hello everybody,
I got my G2 some months back, and in almost a week i installed a custom ROM, cm exactly. I can't remember exactly, but i am fairly possitive that it was overheating since i bought it.
By overheating i mean 65-70something C for running every game, even when watching videos on youtube.
I have changed a good amount of rom, have bricked it once or twice, but now i am running the 05/05 nightly of BlissRom. It is running very smoothly, with no performance issues, but it is overheating like crazy on what i told you about. I don't know if it is standard for that phone. And when i am charging it is around 60 C. I use cputemp to tell the temp.
If i have to return it, will they check if it is rooted and not repair it? If i return to stock via LG Flash tool will they still be able to tell?
Thanks and sorry for the messed up post.

[Q] Battery issue. did I fry something?

I have recently rooted my phone and have had battery issues since. What happens is using my phone in a normal temperature environment my battery gets hot and puts my phone into hot reboot mode until I take out the battery and put it in front of a fan to cool it off. I've tried using different batteries and my phone still does it. Any ideas on what it may be or should I in root it and take it to Sprint? I have the most recent sprint lovers evolution beta 2 updated my kernel and radio also. Thanks for all/any help I can get..
Sounds like a phone problem, I've run quite a few roms and haven't had that happen, even in 90 degree+ weather. I would take it in to sprint
We're comin from a pure power source.
Thanks! Ps I've heard that sprint recently gave the ok for techs to work on rooted phones. Anyone know the accuracy of this claim? I heard it from an employee at a corporate store but he was wrong about another issue we had...
Just leave S-Off, in case they take the 2.3.3 OTA in-store. I usually have S-Off w/ stock ROM, no custom kernel, so they can't blame rooting for battery issues.
I had overheating issues with my battery on standby and random times, so I took it in. They gave me a new battery, problems persisted. Took a screenshot with the temperature shown, took it in. They ran more tests, blamed the motherboard, and gave me a new phone.
Be warned, you may get a replacement with 2.3.3...
I would flash a different rooted stock rom anyway and see if the problem persists. I have had this problem before and flashing a different rom fixed it.

[Q] Heat issues on cm12

Hey guys, so i flashed cm12 official on my phone 3 times by now and always when i used my screen my phone got really hot. So i went back to stock 4.4.2. im having a d802 from tmobile germany. And i think when i flashed cm11 earlier i had the same issues. I also tried setting down the cpu clock frequency to 1500mhz which also didnt help. Also battery life was worse than stock on both cm11 and 12. So do your phones also get hotter on cm12? Does anyone know if there is a solution? Id really love to use cm12 but im afraid of destroying my phone bc of overheating. Also i think the battery life is better tlon stock. Not to mention the camera, but i prefer cm12 though

N910c overheat

Hello everyone,
I'm dealing with overheat issues on my note 4 exynos model. I bought it November of 2014. Everything was fine ultil lollipop came out. I was completely stock and after lollipop I had a huge drop on my performance. So I rooted my phone tried different roms and kernels. I didn't find a solution so I went back to stock kit kat where everything was fine. After 2 months I got the update to lollipop again performance was normal but since then I'm facing overheating even with minimum usage. My cpu temp i's from 38- 70 without even gaming. Could be a defective phone or am I doing something wrong? Anyone else facing these issues?
For your information I did wipe catche dlavik catche. Restore to factory settings and I'm not using an sd card.
Should I go to a Samsung service center? I don't have warranty now, but I've heard people saying that they don't always check it if phone seems completely stock.
Thank you in advance.

Dont know what is the problem but the result is turning off the phone

Hello thes will be a long story so get ready to read it all if you want to help!
First let me start with the day i bought this phone. Okay it was sth like 21 dec and i bought it. The thing is that i am really crazy about installing custom roms and stuff on my phone. So i bought this N910C with the home that i wont do anything because its price in my country(Bulgaria) is basically the same as it was a year ago, saying it is expensive and i wont dare to do anything with it because i will loose the warranty. We here receive new tech later. Okay, im lusing the point.
Well by the title you know... i did not just something but many things... one week later i was annoyed of the laggy old Touchwiz for the Note 4 and decided - I will do it no matter what. So i looked up the xda site, found my model and then installed recoveru and curtom ron (Sixperience v4 or v5). So everything was smooth but i started to get more curious about other roms. Then started surching and then installing new one almost once in a day. I tried the Dytto, CM13, CM12.1, lollinox, Wanam lite, Sixperience, ERobot.
Okay and after 2 and a half weeks things started getting weird af. Well back to this day i was with Sixperience and it had that weird bug with random restarting just you know because bugs. And IThought that with new rom it will get this thing out. But guess what... i installed maybe Erobot again (i dont really remember which is sh i t because it is important but its been a while).
So then it was all okay, for couple of hours i was watching youtube videos, browsing the net but the battery ran out of juice so as im suposed to do i plugged the charger. Then i left the phone and went to bad because it was like 1 am.
And then W T F... Im the mornig i woke up and started browsing trough facebook fast beause u had to get up to school. My classmate came and i unplugged...Making2posts

Click to expand...
Click to collapse
So i went to school. In the breaktime i got my phone to surf the web a bit and i saw it bootlooping and it was hot af... so i thought well maybe the rom didnt install properly.
After school i tried installing another rom but the same problem... Then i got back to stock from sammobike.com software and odin 3.9.sth. And nothing this problem again.
The really f'd thing is that it is working properly when im charging it like on cable always working with no probem. Also with an expernal battery pack.
So my question is Whyy.... And can you help me to fix it... I'll respond to every question you guys ask... Just cant live with my phone wrapped in cable and like old cable phone. And by the way... yes i tried different original battery and it isn't working too.
Also another weird things. Now there isn't a bootloop but only 3 sec working off the charger then get in sth like restart... I mean showing samsung galaxy note 4 logo and the it is turning completely off... even not showing the boot animation.
And by the way sorry if i have mistakes but im writing fast. I hope you will understand the most.
Thanks for reading that long post!

Please help! Note 4 throttling without heating up...

I don't know if this is the right place to post this.
Summer 2017, I have bought a refurbished Note 4 SM-N910F from a local dealer for €300. I immediately rooted it with TWRP as recovery.
I didn't knew much about tweaking back then but I came across apps like Greenify, L Speed and HEBF Optimizer.
However, few weeks later I managed to soft-brick it.
I brought it back to life with a stock rom found somewhere on this site.
Months later I screwed up by bricking the damn thing again, I installed Nameless rom but it had terrible heating issues, even after a week.
I got back to stock again a few times with Emotion kernel installed.
Current situation:
I am now on stock rooted MM with stock kernel.
I have issues with my phone while gaming. It literally throttles the CPU speed down to 1190 MHz in less than 10 minutes while it doesn't get even warm, literally no sign of high CPU speeds at all.
Now I'm on Xposed (Wanam's build) and installed DVFS disabler. The problem is gone.
But now my phone gets warm even while web browsing, and even with the same games where it didn't heat up before
Please help guys I'm sure you know more than I do.
I just want to play games without heat and thermal throttling just like before...
