Why is there so much hype towards ROMs and kernels? - ONE Q&A, Help & Troubleshooting

Hi all
i had my OPO for 2 months now
and i decided to root my phone and try some custom ROMs and kernels since they're so popular , so last month i rooted my phone and take a spin on those famous ROMs and kernels ( partly is also the touchscreen issue and random reboots are driving me nuts ) i won't specify what ROM or kernel i am using though
first impressions when i had a new ROMs is that , there's nothing much that is different i though things would be faster snappier with a new kernel built in but ...my OPO did not , my phone did get more stable but it did suffer from multigesture issue once and force rebooted 3 times in the span of 1 month , but the biggest issue is that my phone keeps getting systemui has stopped working , multitasking button gets bugged one too many times , wallpapers constantly missing when i unlock my phone and animations are very clunky
so yesterday i decided to go back to stock just to remind myself how stock feels , using NANdroid backup i restored everything and...
stock 44s feels so much better compared to custom ROMs which begs the question
why do people deviate from stock ROM on OPO ? stock cm is pretty sweet , I understand rooting the phone to get xposed etc but custom ROMs just don't feel right on the OPO ...so is it just me ?
still props to all the devs out there , no offense just my 2 cents

I think if varies for the phones and locations, but I was getting some pretty beastly battery life, smooth/fast experience with vanir and Franco. For some reason I just didn't like stock and was not getting as great battery life. I've tried many things and some are good, but there are better (to me at least). I'm just running Lollipop now and can't seem to go back to kk.
It all comes down to ones preference really...

wait , isn't cm12 for OPO currently a little unstable? i really wanted to give it a shot but i fear that it is too unstable for a daily driver

Working fine for me; I don't think it is to the point where it can't be a daily driver. I'm really liking it so far, the Lollipop experience feels really nice and smooth.
Check comments from others on the threads to see the kind of issues they're having. Devs are doing daily builds so as days pass it gets better and better.

Sounds like you didn't do any kernel configurations at all to experience changes.
On AK, with Synapse and UKM, you can change numerical values to configure how the phone handles processes. Default kernel settings aren't optimum for every phone.
My settings consist of: slim (300-2457), CPU boost driver (10ms, 1574MHz, 30ms, 1190MHz), CPU Volt (-35mV), I/O sio @ 1536KB read ahead, drop caches, laptop mode, Vibrator at 25, Fast Charge at 1500mA, C1 (Retention) disabled, 120 second Wifi Scan interval.
With those settings, it makes a HUGE difference compared to stock, as well as fix bugs (screen artifact/tearing) before they were fixed on the latest firmware, and increases battery life by 1.5 times stock.

I have the same questioning but without any problems that you had/have/ My phone works perfectly ( crossing fingers ) and i've had it since July. I always used to ROM my S3-S4-S5 to get a new feel of the phone, but with the Oppo i don't see the reason to. Maybe it's because CM is pretty near pure stock Android, and that's what we get when we switch ROMs on big brands.

OP, it is not just you. Folks who mess about with custom ROMS, as the other posts here share, do so because they can customize the total phone experience, leaving things off, and putting other items on, to their liking. Giving that the background OS is stable, and the apps a person selects are stable, there should be little to no difference in 'performance', overall, due to the apps. However, you may get performance differences because there are less TSR's currently running in your system, so more memory is available, etc, which can make mainline apps run faster.
So many reasons to do custom apps.
As you said, and I agree, CM is a nice, generally smooth OS/ROM. I am coming from an LG G3, which I like very much, but to customize (remove all the junk), and fine tune (remove Google calling home = less battery live, etc), it take's some time to setup those conditions. With CM, most of the junk is not present at the onset (AT&T largely). Much more clean. I would like Google to be disassociated from CM completely, so that it is an add on only, providing better control of the base CM. I would like this in an official CM ROM/official variation.
That is the reason I have/am switching over to the OnePlus. I have tried a few custom ROMs as well, and the stock CM seems to have the best stability, reliability and consistency, to date. I suspect that will change when a large update comes out, such as L, and a great amount of energy goes into that development. I just changed from 38 to 44 last night on three OPO's. It took 5 minutes, or so, a piece, and all of the data/previous apps, setup etc, stayed with the updates, making for an all too easy update.
Awesome. Next will be "L". I will wait for the CM official, as that will likely be the most stable, as I suspect it is getting the most attention from the CM team, at this time. CM is a pretty nice OS.

[Q] To change ROMs or not

So I typically root almost all my android devices once I get them. My Infinity was the first device I tried keeping stock unrooted as long as possible. I will be honest with saying that there were some times that I didn't even think about the fact if it was rooted or not. Unlike my phone I really only use it for class from time to time to take notes and mostly read books/comics or play games. However, I was utterly floored by the speed difference that my friend got out of his by rooting his. He picked up a TF700 about a month ago from ebay and rooted it the other day. We then spent yesterday testing it out with similar loads. His battery life was about an hour better than mine doing relatively the same thing (head to head gaming), watching netflix, and browsing a few comics. What really got me was the speed and decrease in lag. Honestly I didn't even realize the lag was so bad on mine (I guess I had grown use to it) compared to his.
So my question is this: Would I get even better performance / stability / battery life out of changing the rom to say Cyano or Paranoid or is the stock ROM minus the apps and a few tweaks from the threads the best I am going to get?
If anyone has any expriences they are willing to share with me I would greatly appreciate it.

I personally like Cromi/Cromi-X. I used Cyano for a while but settled on Cromi for the speed. Cromi is based on stock and optimized for speed, so if don't care about additional customization, I would say go for Cromi. But you will lose your warranty if you unlock the tablet to install custom ROMs. Not sure about stability/battery life improvements but I've never had issues with either on Cromi.

This is my two cents. Any custom rom and kernel that you pick will be faster than the stock. I am using Cromi X 4.7 and Hund 3.3.2. I believe that they are very major and stable. The battery life is depended on how you set your device up. Wifi and screen brightness are the most battery consumptions of all. You can go to the wifi advance setting and set it to never use wifi during sleep. You can lower the brightness of your screen unless you are outside to use the ips+. You can also set your turn off screen to one or two minutes before it goes to sleep. With all of that can give more battery back. You will be happy with Crmi X with your choice of kernel..

I wanted to thank both of you for all the help that you have provided. This was great advice and Cromi-X works amazingly. While I was drawn to CM by its features, trying out the speed of Crom definitely was a high point for me. The difference from the stock (even stock rooted with apps pulled) and Crom is night and day.

My opinion why you shouldnt flash your Galaxy device

To start this thread off, I will start by saying ying I am not bashing the developers in any type of way, just giving people my perspective and opinion.
Hello guys,
Let me start by introducing myself. I'm not new to this forums, ask many questions and do lots of research and from my research here is my conclusion.
People normally say they want a custom, stock feel of an android and that's why they flash rooms. If you want a pure droid feel get a Nexus device simple as that. Why flash a rom that takes away originality from the device? Things like S Voice, Samsung Watchon, multi window mode, WiFi calling and etc are very useful in everyday life. It's also what makes the phone better than an iPhone in opinion, the only advantage I see with roms are slight speed advantages and honestly, it isn't by much. I feel like roms are only better for games but if you're rooted, you can over clock your phone when you're playing games and problem solved.
I didn't go too much into detail, just stated a few reasons. Feel free to drop your opinions though, I'd like to hear why some of you think custom roms are better.
i rooted my s3 for the first time a few weeks ago, and the main reason was because i wanted the new 4.4 and heard that it wasn't going to come out for a LONG time through an official update. i was leaning towards buying the nexus 5 but when i found out i could flash a custom rom i tried it right away. i'm extremely happy with my decision because the new rom has been stable and makes the phone brand new again. like you mentioned, its much snappier without all the extra samsung extras.

you cannot overclock your phone by rooting
you need custom kernel for that

Actually, you can. I've overclocked my phone lol.
It's not just for better performance but in custom ROM everything is better, such as battery life, it's the most important thing after performance.
You can also take the full control of the device after root and install a custom ROM. Games also is very important point for huge number of android user, because the stoke (original) android system cannot run games as smooth as custom ROMs.
Another reason is the lag, lag is a big problem in any android environment and up to now there is no solution for that, however, custom ROMs reduce the lag and make a better feeling for the user.

Not in all cases a ROM makes for better performance, and in some cases it actually makes it worse if the ROM is not properly configured. But a ROM can give the device a plain android version without the bloat software from the device manufacturer, thereby increasing performance and stability. In most cases I don't think it increases performance over plain android other then giving access to overclocking and scheduling options

[Q] Phone is Lagging and Overheating Constantly - Want to Install Custom Rom - Which?

Hi there,
I am sort of new to rooting and have never installed a custom android operating system or ROM yet. I would like to put on something with Android 5.0 if possible, but if none are out yet, which is the best ROM to put on my LG G3, and a tutorial to do it?
I want to use all of the eatures of the phon still as well.
Are there lollipop ROMS out yet for this phone, and if not should I wait for it?
Thank for your help.

I too am using Cloudy and find that the top half of the phone doesn't heat up as much. There's an eco mode you can turn on as well. Not sure it that's what's going the trick, but I've kept it on because the battery life is great now.
As for the lag, have you tried flashing Pure Performance X? It's made all the ROMs I've tried snappier (including Cloudy).

I'm using Viper for my third day now. The first day the battery drained really fast as google processes was raelly active, but the last two days ive gotten over 4 hours of screen on time easily and it's definitely been an improvement over stock for me. I havent played any games but phone did not get hot watching youtube vids.
I am not familiary with pure performance X, looks interesting though.

Hello everyone I have just joined this forum about two days ago. I own a oneplus one which i found to be one of the finest smartphones until CM12 came along. It seems to me that CM12 ruined battery life of the oneplus. With CM11 battery life was much better, even charging time was not more that 2hrs max. Now I have read the forums that many oneplus owners experienced the same issues.
Now the thing is that I do not have any experience in how to root my my phone or install kernels and other stuff. Is there anything that would help my phone to have a similar battery life of CM11?
Thanks

I take it you haven't unlocked your boot loader yet?
Unfortunately 5.0+ seems to be a bit poorer in the battery dept for most people. Most are hoping 5.1.1 helps the battery life, if not we'll have to hope for android M whenever that arrives. If you had an unlocked b/loader and custom recovery you could tryout some custom roms. Or even flash a 4.4.4/kitkat rom as many (including myself) have done. I had installed multirom and have been running COS12 as the main rom and CM11S on the secondary. The battery life was/is so much better, I was hitting 5-6hrs screen on time over 2days from a full charge, with lollipop I was hitting 4-5hrs screen on time over 1-1.5 days at a stretch., the standby drain is also a lot more.
If you havent already done so you could try checking privacy guard and denying wake up and keep awake permissions to google play services or anything else that seems to be active a lot in the background that you think shouldnt.

No I never unlocked anything. the phone is just unrooted. What I only is just change themes, which seems also to be buggy. So is it possible to revert back to CM11s? Are COS12 and CM12 the same or different please?

It isnt possible without unlocking your bootloader, see the below guide if you want to look at that option. It seems a lot of hassle but once its unlocked, thats it, it wont lock again unless you specifically go through running a command to do so. As an added advantage you can install a custom recovery which will allow you to make a full nandroid backup, which you can keep on your device or copy over to your PC. You can use this if you ever run into any problems or if you want to try out some other roms, you have the option to go fully restore your last setup.
I dont think I've had any issues with themes, is it one in particular or all, what happens?
I believe we are referring to the same thing, COS12 (Cyanogen OS 12) is what the oneplus one runs out of the box (stock Cyanogen OS). CM12 which is what it also gets called can also mean the CM12/12.1 nightlies, which can be flashed like a custom ROM and are considered the most up to date (on the bleeding edge if you like).

A good reason for Miui

Many of you probably have already noticed that this phone overheats when playing some heavy 3d game... Even with some benchmarking...
And due to that you have probably experienced some nice lag while the phone is overheated...
Well, I have experienced that... In real racing for example... And after having tried all the roms available and have only used miui when I bought it... I now got back to it.
And guess what... Besides the good look, the unbeattable camera app... I now realized that in miui, my phone does not get half the heat it got with cm, pac or lately with broken rom... Why does it happen I dont know... But the truth is miui is very fluid, the phone does not overheat anymore and I play real racing without any lag...
You should all try it...
Miui dev rom in my case.
I'm using brokenOs with a modded thermal conf (got it from here on XDA forums) + kernel configs (used some configs discussed in the CM threads of the TS forums, applied using EX Kernel manager, but could be using the embedded kernel auditor) and I'm getting a much cooler phone and much better battery life than I ever did with MIUI. Not to mention a completely lag free experience like I was never able to get with any miui (eu, smiui, even chinese dev rom).
The camera app is probably the only thing the original miui has that I still think as a better software piece than any other on the playstore (althoug, you should try cameraMX. It's brutally good).
I used MIUI for a couple of months and initially gave it the benefit of the doubt. But no, I won't go back to it again now that I've tried others.
