[Q] Why does most ROMs overheat? - Galaxy S 4 Q&A, Help & Troubleshooting

Hello, for about 2 years, I was completely stock and rooted, and I liked it that way. But since i've seen many developments, I decided to go for a custom ROM.
For Stock based lollipop ROMs, most of them overheat for no reason, before I have even set up the phone.
On CM(12.1/12) and AOSP 5.1.1/5.0, it overheats and it sometimes turns off itself.
I have had NO issues of overheating on stock over the past (not lollipop).
Any ideas? Is there something I am doing something wrong, because when it overheats, it gets unusable and I am unable to even touch the phone!
Thanks.

It's not the ROM, but your S4. I've installed AICP, TeamUB, and JDCTeam Cyanogenmod-based builds, and at no time have I ever encountered this issue on my device.

It is weird as on stock kitkat it was perfect and as soon as I installed a custom ROM, it overheats.
Only on AOSP 4.4.4 it doesn't overheat

Part of it could be Android 5.x itself, but at worst you'd get a memory leak, and a memory leak should not cause the S4 to overheat. Have you had someone look at the S4, to make sure it isn't a hardware issue of some sort?

Is custom ANDROID 4.3 rom really smoother versus stock rom?

Is custom ANDROID 4.3 rom really smoother versus stock rom? it doesnt have the lags/stuttering that stock rom has?
I've D802 International...
Thanks!
It's strange, I have the VS980 Model (Verizon) of the LG G2 and stock had zero issues with "stuttering". I installed clean rom, no stuttering, and I am running an AOSP version now and again no stuttering...
Are you sure you don't have something installed that might be causing the issues you describe? Maybe factory reset, choose not to restore from google, and run it for a few days and see what's up.
This is by far and away the fastest, smoothest phone I've ever owned. S3 -> Note 2 -> S4, etc.

D800 question

I'm kinda lost here. I'm looking to buy a D800, but wanted to know if root and leave the phone free to install aosp roms like CM11 will be possible and not complicated as hell. Wich are the steps I should follow to root / unlock, install twrp, and backup the original rom? (To later install CM11)...
Please any advice, links, etc will be greatly appreciated. Cheers!
The phone itself is good but the stock software is annoying. There are stable aosp roms available, but they have all very bad Cameras and inferior battery life. So basically most people would be forced to use the crappy lg stock rom anyway. Rooting is very easy as well as recovery
Oh that's bad news... had the idea to flash it with CM11 (while 12 is under development), or G3 roms, some people had told me this phone were good with AOSP roms... It's only the camera that does not work as intended on aosp roms? No fix for battery?

I have D800 and it really isn't as bad as people make it out to be. I can get 12 hours of usage on CM11 with 4-5 hours of screen time. Stock Rom is fine but then again I use the T-Mobile stock Rom on mine when I'm stock or CloudyG3 Rom. Right now I'm using Flyme OS Rom and I started this morning at 45% and was at 7% after 12 hours of work and had 4 hours of screen time.

Yes I'm about to purchase a d800, if it is good with CM11, then its good for me. Maybe later it will have lollipop roms and that will be another era... Thanks for the answers! Cheers.
Hey FedericoUY, I received my phone about a month ago and I'll go through my journey from all of the likely problems and what's required for unlocking, rooting, installing a rom for the first time on this device. I'll describe the benefits/disadvantages from the different rom distributors recommended for this device. Until a few days ago I would have agreed AOSP was better left avoided on this device, and why CM11 is still not recommended for the G2.
When I received my G2, while I had the intention to flash it. I was gravely disappointed with it, because of the shocking software and default setup. But it's become my favourite phone since. I too thought CM11 would do it for me, it really didn't on this phone. And the display & specs make it seem extremely outdated, not to mention none of the phone-specific features really worked.
(In order of events)
Sim Locking for AT&T (do first)
By default it's locked, as I imported it through the US and without an account for them I had to purchase a 3rd party unlock code for $2. Strangely I had to keep it unlocked on the stock firmware for a certain amount of time (tried a day) before it remembered the unlocking when flashing a custom firmware.
Rooting (do secondly)
The only method which worked on the latest G2 stock rom was to use "Stump Root" in the "Brute force" mode as the latest rom version didn't have a pre-configured rooting routing.
Installing a custom recovery (do third)
The only method which worked on the latest G2 stock rom was an app called "D800_AutoRec.apk" which just installed the latest TWRP recovery, from there I could flash anything.
Which roms are decent for the D800?
While personally I've stayed with more AOSP roms like CM and AOKP, the best rom & kernel to use in terms of performance/battery life and phone specific features is not the stock G2 software nor AOSP. I'll explain further why.
For the kernel, the arguably most matured and feature rich, battery friendly and performance suited kernel is the Dorimanx kernel. Which is unfortunately only compatible with stock G2 & G3 roms.
With this in consideration and all of the improvements in the G3 firmware, fully supporting this phone's features, makes the G3 roms peoples choice, in particular CloudyG3 targeted for the G2.
When it comes to AOSP like roms, there is two okay kernels which are compatible with CM and the other is only compatible with AOSP roms, with a few exceptions. Both of these kernels have poor battery life in comparison and produce a lot of heat, not to mention lesser abilities in terms of tweaking (overclocking, underclocking rate, faster charge, etc). It generally only gets worse from here using rom released kernels. It's fairly uncommon for features such as double tapping wake to work, and the lack of on-screen keyboard usability improvements.
However, Lollipop has turned things around. While not flossing as much battery life savings as CloudyG3 with the Dorimanx kernel, performance, design/look (can change Google keyboard to old theme) has brilliantly increased. It's been the only close to stock rom I've ever been largely happy with. Despite not having any real CM features and a few bugs at this moment in time.
Therefore, if you like the ability to tweak and charge faster and overclock a lot with great battery life I suggest CloudyG3 and Dorimanx. If you want an AOSP rom, I'd use Lollipop. If you want a full featured stock rom with a nice kernel, I'd wait awhile and opt for CloudyG3 until lollipop roms mature. For a battery comparison, the stock G3 rom with a custom kernel lasted me 5-7 days without charging, with CM11 I can only get about 1 day if I'm lucky.

ROM Advice

Hi All,
I have had my Galaxy S 4 (I9505) for a while now but it is still running android 4.3.
I was hoping to update it to 5.0.1 but when I plugged it into my PC, Kies said 'This device is unsupported'
I want to flash a new rom onto it (I have done this in the past with a samsung tablet)
I was just wanting some feedback as to what is regarded as a good rom for it these days. Should I go a standard stock rom from sammobile or are there custom roms out there that perform better?
Thanks for any help and advice.
Daniel
Custom roms give you more performance. Stock roms tend to lag here and there, from what I saw in rom reviews.
If you want a minimalist rom, go for CM12 or Slim roms. They have very few features.
If you want lots of features, go for AICP or Resurrection Remix. These two combine the most popular features from other roms (I personally use Resurrection Remix).
And there are the GPE roms. I don't know how GPE 5.1 is, but on 5.0 the rom was rock solid and everything worked.
I can't say anythinv about stock touchwiz because, since I changed I never went back

Try a custom S6 Touchwiz ROM for your phone model - you'll be pleasantly surprised by the new look, feel and performance. I know I am!
I tried CM but not such a big fan... Experiment a bit until you find what you were ALWAYS looking for!
You try to consider CM 12.1 or GPE Roms. The major disadvantage is the camera quality and some multitasking features on TW, but it's hella fast and smooth.

Roms
I would recommend Cyanogenmod but sometimes it comes with some problems. Check out first which is the stable version for s4.
Also, I would recommend the WickedRom which is great and great performance. And the WanamLite Rom is amazing if you would like to tune your mobile , for example gpu or cpu in higher frequencies or even set custom gestures and etc.( but remember to be careful with those why you might break your phone

it's like you have already a custom rom, or a rooted & modified stock rom !.

go for Resurrection Remix like said: GDReaper, or may be BlissPOP ( with terrible battery drain for me).
I tried just the straight CM 12 rom and it was okay, but once I put on the one of the Optimized CM 12.1 roms I got better battery life and faster performance, but also lost a few features, got a few bugs, but so far so good. It really depends what you want.
If you are willing to have a few crashes, bugs you can put on the newest rom builds, but if you want stable, then going for the older well established ones may be a better option.

I have to correct you here buddy It's almost always better to pick the latest CM build. Because it's a work in progress, every new build has a lot fixes.
I'm curious though to what bugs you are referring to. I used it pretty long and I found it almost to be bugfree. Besides the obvious difficulty's with bluetooth.

Hey Lenny, the official CM builds I have never had an issue with (except nightlies of course) however when we get into the custom ROM world such as Slimroms, modified CM builds etc I do tend to hit a few bugs, such as crashes of apps, however often those builds then become stable.
Hope that makes more sense?
The only good advice is to just use stock roms. It's stable, no bugs, no issues. The only thing that pisses you off is the laggggggg!

Stock Lollipop or ResurrectionRemix or Any other custom ROM?

Hey there!
I'm pretty new here. Anyway, I was wondering if I should go ahead with installing the stock Lollipop update for Zenfone 5 or should I use a custom ROM, say, ResurrectionRemix? I've been checking on this for a while now and found out that the Stock Lollipop ROM has battery and heating issues whereas ResurrectionRemix has GPS, FM and slight stability issues. Also, camera not working after unlocking bootloader seems to be a common issue. So I'm not sure which one to install. I love both the interface and style anyway, though I've always had a thing for the native Adroid Lollipop style.. Could you also suggest some other nice ROMs out there?
If you want to try something new, go for Custom ROMs.

Is Dirty Unicorns Dead? Suggestions for other clean-style roms?

Trying out a Sprint S4 (non T version), but not thrilled with the performance of the stock 4.4 ROM. Figured maybe 5+ would be an improvement, but wanted to go with something built for speed and efficiency (ie. not full of bloat) rather than let it update itself.
From what I've read, most people seemed to recommend Dirty Unicorns as a fairly clean and speedy ROM. I'm not looking for heavy modifications and skins or anything like that. Those kinds of things turn me off.
But, it seems that Dirty Unicorns is no longer supported on the S4, the links in the official thread are broken and the DU website doesn't list the S4 as a supported device... oddly, none of the Galaxy phones are listed as supported devices. Were we dropped? What happened? Is it still out there somewhere? Is there any other similar ROM that folks recommend?
I've got TWRP ready to go!

BlissPop is a great 5.1.1 ROM, CM13 is also a good 6.0.1 option. If TW is your thing, WickedX is your best 5.0.1 choice.

I don't particularly care for TW or not, I just want to make sure everything works as well as possible (sometimes AOSP roms need to be coaxed into working more than ones based on stock). Also things like Samsung's pedometer (S Health) have replaced my fitbit, and I'm hoping whatever ROM I install will still work with it.
Meanwhile, I can't believe I forgot about CM! I should have thought of that first. Those are always solid once they are officially supported by CM! But I wonder- is CM12 better on this hardware than CM13? In my experience over the years, I've often found that ROMs based on versions officially supported by the device worked better than ones that were pushing newer versions. At least CM12 is based on Lollipop, which IS available for this phone officially. But then again, this is CM we're talking about. If 13 works well, I have no qualms using it. Any advice on that one way or the other?

I haven't had any real problems on stock CM 13(officially supported device), I run SynergyOS which is cm based so I can undervolt and underclock. You can get S Health on CM ROMs if you go that route.
