[Q] Stock and Custom ROMs - Essential Phone Questions & Answers

Im a tad confused... are there just enough differences between stock and LOS/AOSP roms that it really warrants separate kernels?
Stock seems pretty darn close to LOS to me...

Far more to it than the differences on the surface that you see. With regards to your concern about kernels. Most of the Pie rom's here use EAS kernels which at this point have made the default HMP kernel on stock fairly meaningless. Performance and battery life has become so much better now that the most used kernel Artemis has matured alot. Alongside Neutrino as well. Either of these kernels offer better performance and battery life over stock. So this won't be a different in features or amount of apps installed but rather almost a very different feel to the phone. Case in point scrolling on large mounds of text or say the Play Store is leaps and bounds smoother on an EAS kernel vs an HMP kernel. Hope this helps

oh i definately get the benefits
on exkernel atm, and live the differences it made... i just dont understand why we "cant" use the same kernel on a LOS rom.
there only differences i really "see" are some extra framework files

Out of these three ROM's, which is best?

In terms of stability, built-in features, battery life, performance and anything else important that I might have forgotten, which of the below three ROMs is top dog? Just so you know, I plan on flashing the non-overclocked GPU version of _motley's Linaro kernel regardless of which ROM I choose.
Paranoid Android
Glazed
JR6

I'm running paranoid myself but the best advice I've read when people ask this question is try them all. What's best means to me might not be what it means to you. I've tried all three myself and they were all stable, I like paranoid because of the per app density feature it has. It was just updated again today btw. Motleys kernel is awesome I like the one without gpuoc. Good luck, happy flashing
Thanks for the advice. Also, I have another question for anybody who can answer. These three ROMs seem to be mostly similar in terms of features, so it's actually kind of hard telling the differences. So, what I'm trying to ask is, what sets each ROM apart?

Does anyone know the answer to this? I used JR5, EOS now PA. They are all very similar, as you would expect. PA has more config options for setting up tablet UI which is key for me and the reason I use it currently (with Nova Launcher).
I liked JRX Roms as they have lots of apps inbuilt that the others dont, ie working Flash, GAPPS etc.
I'm also using Trinity kernel which is working great, again, I have not noticed much difference between them all.
Try them and take your pick
I say EOS with Mortley kernel

Currently the best custom rom?

any ideas here guys? i really wanna flash a custom rom, but which one is currently the best?

It really depends what you're looking for in a ROM. There are a lot of different ROMs that are currently available depending on what you want. Whether it's a stock feel (AOSP ROMs), customizability (AOKP, PA), CM10 of course, and more. I highly doubt anyone has tried all of the ROMs that are out there so go into the dev sections and do some reading and see what you like! :good:
Really too subjective of a question to ask. "Best" is the ROM that contains everything you're looking for.
The best custom ROM for me is CM 10.1's nightly builds. The best custom Kernel for me is franco.Kernel. Both together = awesome (for me)
Thanks guys . I realise its a subjective view but thanks for replying

Whatever ROM you choose, I second using Franco kernel :good:
I've been running a CM10.1 nightly with no custom kernel, its been pretty solid. I might have to check out Franco's kernel though, I'd like to try out undervolting for better battery life and heat at some point.

I've always understood this, but never really knew where to look. Is there some place that has a list of all the kernels and ROM projects and what their goals are. User reviews would be pretty handy as well.
As others have stated, this is very subjective. For example, I'd recommend AOKP. Not because it's the best per se, but because it's the one I'm using and I'm quite happy with it.

There is a list here: http://forum.xda-developers.com/showthread.php?t=2003731
But you will have to read up a little on each one for specific features, bugs, and user reviews. Many ROMs with lots of features sound great but in practice aren't the most stable. Most bugs get ironed out in time by our great dev's, but its something to consider. When in doubt, flash & check it out!
For the record I use schnip's AOSP ROM w/ Tablet UI + Franco.kernel = clean, fast ROM with tablet interface. Can't ask for much more.

Hey I was considering using this combo and I just wanted to know if the native OTG support still functions after you flash the franco.kernel?

I honestly couldn't tell you since I don't own an OTG cable but you can flash franco's kernel and test it. If it doesn't work just reflash the ROM (without wiping) and you'll revert to the original kernel without losing any of your apps and data.

Seems to be by far the best kernel for dealing with the throttling issue that exists with our device so far...
Installed aokp . loving it.

At this point, I've gotta give it to AOKP. Lots of customizability and very smooth and quick. Rotating 180 degrees has no noticeable lag for me.
Paranoid Android is one of my all time favs in order to maximize your tablet space by altering app DPIs etc (not that you need to with a tablet this large). MMuzzy's ROM is a nice AOSP replacement which is what I'm on currently. As far as kernels go, it's really up to personal preference. I'm on KTManta (ktoonservative) and it flies though sometimes I get the lockscreen (black) of death - not waking up from lockscreen. I bought Franco's app ages ago before I got a tablet and can vouch that he also builds a strong/stable kernel.

Best I9505 ROM for gaming performance?

Hey guys, first post on the XDA forums so I'm hoping i don't duck this up or post in the wrong sub-forum.
I'm looking for the best gaming/performance centered ROM available for the Samsung S4 -i9505. I've used THOR for a while, but moved onto WizCyan to test it out and I had the same lingering feeling of a lack of RAM that caused stuttering in-game, especially with WizCyan. I'd like to ask what you guys use for gaming/your daily driver and how good it is performance-wise. The most intensive stuff I do on the phone is usually NFS No Limits on High-Medium graphics settings. I'd love to get some community input on what is valued as a primarily performance centered ROM. If said ROM also had a feature or way to switch to a more battery centered mode,that'd be fantastic too but I understand if such a unicorn does not exist. Any and all input is appreciated, thank you!
Side Note: I have read some of the suggested threads, but they're all quite old and lots of ROMs have been created and updated, so I wanted to see what the scene is like now.
If you're looking for gaming performance, an AOSP-based ROM such as the ROMs from JDCTeam is probably best. The ROMs you've tried, while they all have had much of the annoying software from Samsung stripped out of them, all have the Touchwiz skin still applied, which has been demonstrably proven to have a negative effect on performance.

Thank you for the reply! I'll definitely check out some of the JDC team releases, hopefully Shark Jungle has some reviews on them. Have you tested any? If so, which one did you prefer most? Thanks again for the advice!

Yes, Shark Jungle did test some. But he thinks TouchWiz ROMs have better gaming performance than CM or AOSP ROMs.
I would take that with a grain of salt, but it's up to you to decide.
Anyway, there aren't many JDCTeam ROMs, it's just Android versions that differ. The main branches are Optimized CM and AOSP.
I would recommend the AOSP branch, as it seems generally faster than CM. It may be because AOSP is less cluttered, while CM has lots of CM stuff that may bog down the ROM.
JDCTeam ROMs come bundled with a custom kernel. It has 5 predefined profiles, ranging from extreme battery to extreme performance (that's the profile names). The extreme performance profile is almost the same as setting your CPU Governor to Performance. You get the same speed, but with the advantage of your CPU not being stuck on the max frequency.
And then there's Slim ROMs. Similar to the AOSP described above, minus the custom kernel. But you can use Kernel Adiutor to adjust some of the stock kernel settings and create a performance profile similar to the one found in the JDCTeam kernel.

Thank you for your help mate! I went AOSP, the RAM availability is great. After switching to F2FS boot times and game loadup times are also incredibly fast. NFS Gameplay is smooth too. Thanks for everything!

I would be careful with F2FS. I had data loss while using that format. And random phone wipes, including internal storage.
This happened only occasionally during a reboot.
If you don't reboot very often, chances are lower of it happening, but there still is a small risk.

Poor performance on most ROMs?

Hey Guys,
i just want to have a little discussion about the overall performance on ROMs.
I hate stuttering ROMs. But what is the reason for that?
New phone + Custom ROM = Great performance.
Old phone + OEM ROM = Not good.
Old phone + Custom ROM = poor performance.
Why?
I had so much 7.x ROMs which all had these little micro stutters in Instagram and any other app.
BUT! AOSP Extended was much better! It had 20% the stutter of the other ROMs.
Now i am using the 8.1 Pixel Experience ROM. It has so much micro laggs. Maybe even more than the other 7.X ROMs.
That's the pure Android experience. And the Pixel phone doesn't stutter.
What's the reason for that?
Different DMs configure the device in different ways. It really comes down to how effective the kernel is configured. It doesn't help that half of use one kernel as a base and the rest use another.

Ramdisk. How the kernel is configured primarily.
Yeah the OP2 is pretty ****ing laggy. Only ROM that salvaged is Vertex 3.6. It has a good kernel, no lags in Twitter, IG etc...

Rooting

I finally rooted and flashed a good kernel, putting it under test ATM.
I wanted to ask if flashing the XXX NoLimits magisk module worth it and really improves the experience on the OP 8 Pro, since it's not a ROM, it's only a Magisk module (flash type).
I don't mean anything to the team, I heard it was great but I just don't want to mess my phone up with modules and other things, thanks

I used to flash xxx on the OnePlus 5, it was a full ROM back then but it was the best out of them all..
If the module is anything like the ROM then yes it's well well worth it, the developer gets so much right so for me it would be a go to ROM / Magisk ROM
I wouldn't even touch the optimization settings and stuff, no modern device needs them.
Maybe only debloat but that's it.

Id 100% turn off the page file no device with more that 4GB ram needs swap storage certainly not a phone with 12GB, the improvement in regards to gaming is night and day, so yep there is that.
Haven't flashed xXx so not sure what is on offer.
I have a saved config file from my time with the OnePlus 5 with xXx so I'll check on that and whatevers new.

Same, I have the 12gb RAM version so I don't think that any of these tweaks would really help, but I'll try some in the future, you know, we don't have much at the moment, the price of the phone is really high.
I run xXx with my own custom config on a OP8Pro 12GB/256GB with most tweaks emailed and zram disabled completely. Runs noticably faster overall. Snappier and launch times are super low. Also, even tho audio is good, the Viper + Dolby mod from xXx takes the speakers to a whooooole new level lol.
I always ran xXx on my old OP5 as well and it was great even tho I switched to Paranoid after a while just because I really love that UI style and customization. When PA Quartz is a bit more stable on the OP8Pro I will switch anyways but with xXx the stock ROM doesn't really miss anything that EdXposed and Gravitybox + Button Mapper + GCam can't fix like battery circle with percentage in it and flashlight shortcuts.

I rooted and flashed xXx along with Smurf kernel but I'm facing some issues with battery life, it's draining slightly faster than before. Other than that, the device is so responsive, fast and fluid.
I disabled zRAM completely and kept it all stock, that's the weird part but I hope I get better results this week. ??

That kernel is all about overclock and obselete poorly coded "tweaks" that are not need on a modern smartphone, especially not on Snapdragon 865.

You know better than me, I'm not much into these things but you know, one that says it's great and the other says it's bad, the only way to know is to test it myself.
I tested the kernel, it's close to stock in terms of performance but the battery in stock is better.
The reason I'm using it is because I'm running xXx module which is best with Smurf kernel but I might get everything back to stock and test another kernel without the xXx module. Any recommendations?
EDIT: I just flashed blu spark kernel, I'll test it and tell you how it performs ?

Haven't flashed it but tbh the 865 is a beast of chip, it can easily run Dreamcast ROMs which is just staggering really. To push the chip any further is just not required.
For me if you can obtain the performance you get from the stock kernel and save battery then go for whatever that kernel is, from experience on all my device save maybe the galaxy S3 the stock kernel usually provides the best balance of performance / stamina, all the more so with current chipsets.
Aim for battery, performance should take care of itself.
If you're pushing for more performance I would ask myself for what?
I personally push my device more than most, not all the time but the emulators I run are probably the most demanding programs you can get on Android, if I'm good with the output of FPS on them at stock then I think you'll be fine too.

You're right, even though I flashed some kernels but I didn't really notice any improvements in the performance, the device is too fast and doesn't need junk tweaks to be improved, but the battery is better now with the kernel I'm running. Thanks for advising me brother
