Develop Bugs

Is The Stock Rom The Most Stable Rom?

I've been wondering. I've tested at least 30 xperia roms. From GB to ICS to Jellybean. And while the developers on this site have done a excellent, the majority of the custom roms, in my experience start to lag after a few weeks. Yes I know apps like Facebook will cause that but somehow I've only experienced none/little lag with the stock rom. So I can't help but wonder, in the long run are the Stock Roms provided by Sony the best? When it comes to the stability factor.

Yes ofcourse, thats how sony made it and they know best for our device.

Sorry to say man but none of JB ROMs can be stable. Even yours. You can only achieve smooth UI and partly smooth gaming (not in heavy games of course) but performance will never be same as GB. And the big pain in the ass is random rebooting when big workload. You're right that JB have better options but that's all.

I agree. A Question can kernels mess up the stability of a stock rom? Cause I've flashed a stock rom on a Lupus kernel mainly for overclocking and I think the stock kernel works better...
Is there a stock kernel available but only with overclocking added on it?

I dunno but LUPUS has no problems with stability. In what aspect stock kernel is better?
You can try DoomKernel. It's probably closer to stock than LUPUS and has overclocking ability of course.

[Solved] Xperia S: need some advice

I'm not sure if this is something that happens to a lot of you Nozomi users, but I can always ask for advice.
I skip from custom ROM from time to time just to know what my options are, either experimental or close-to-stock. And quite frankly it is bugging me, that my ROMs always feel sluggish, even when others say it should be quick or smooth.
I just want to have the smoothest, most stable, least sluggish ROM out there (I tend to demand a lot), and it should stay just that. Not that it's blazing fast to begin with, and decreases in speed in a matter of days.
Also, cleanest way to install said ROM? I want to rule out all possible factors.
I hope you can help me along with this,
rc_enzo

Almost all stock roms will eventualy slow down
All them error codes just gather up
Clearing your cache and dalvik fixes some of it
Also stock based roms will always be sluggish, it seems all stock kernels have a entropy issue
There are tonnes of other reason
If you want a smooth and stable rom, i dont necicarily recomend my rom, each device is slightly different, these nano diferences have a bigger effect
Just try out different roms till youn find one you like
If not that unlock your bootloader and install cm10 or aosp
Letamas aosp is about one of the quickest but its buggy and FXP cm10 is great in performance and feels great
BUT YOU HAVE TO KNOW TO REPERCUSSIONS OF UNLOCKING YOUR BOOTLOADER
(Although unlocked bootloader = freedom)
If you need anything just ask, i didnt cover everything surrounding your point and question

I know how stuff works, trust me.
Unlocked my bootloader pretty much the instant I got the phone, and I've run a great number already. I guess FXP works great, but I've read the weekly updates don't add that much anymore...

Hmmm...
You could try miui?
Or maybe the 4.4 project (once started and finished)
Letamas 4.3 is i think the faststest running rom on xperia s but there are some openGL issues which makes gaming a no no
And kitkat 4.4 is designed for devices with 512mb of ram, xperia s has 1gb but some for hardware and gpu as we know
I suggest either using letamas 4.3 (few not working things)
Or waiting for a 4.4 build
Im not to sure about opensemc, i dont realy remember not to sure about some others too
Conclusion:
Stock = always slugish
CM10-11 = Good but some builds are buggy
AOSP - amazing but buggy and no fully working builds ive seen yet

I'll give letama's a shot then, and we'll see about KitKat. I have a hunch that we will be getting one fairly soon.

RaymanFX i think he said he got it to boot already but he is a super dev like letama
Me and some other people are trying to get Official CM11 (4.4) for xperia s, (petitions blah blah blah)
Me and some other devs are working on AOSP 4.4
So you should see alot of 4.4
Also - read through the bug list of letamas 4.3 build and also notice there are some graphics bugs but everything else is fine as far as i remember
Using letamas 4.3 then going back to stock, stock felt like very slow

You can always make a clean install.. Wiping everything, format everything and then flash.. That's the best way to avoid any sort of problems in any ROM.. As Envious_Data said, there are lots of advantages of unlocking the bootloader.. And btw if you are going with Stock based ROM, i would suggest u try eXistenZ Ultra and Trintity ROM first and when it comes to AOSP/CM ROMs you can try letama's AOSP 4.3 or RaymanFX's CM10.2 alpha3.. I am currently on CM10.2.. Its very smooth and fluid for an alpha.. I am getting better battery backup too.. Although i have to sacrifice 1080p recording for now, but the ROM is definitely a daily driver.. Go ahead and choose to flash any ROM.. Welcome to Xperia S section..

No offence guys, but I'm not new at the Xperia S, have had the device since november last year, running ROMs since early january.
Thanks for the advice anyway.

I've got the same, my phone runs smooth right after flashing the ROM, but then... I don't know, maybe its because of the way we use our phones?
I have compared my XS to my friends XS - his was very smooth and mine - you know. I have unlocked bootloader to make GTA III run smoothly.
And now - I just got used to this, but I hate my phone

Running letama's 4.3 AOSP, and @Envious_Data thanks for the suggestion, it feels truly rapid and it looks like it will do fine for me. That games and 1080p recording don't work properly, is no burden for me anyway.
Good luck on your developing endeavours, I hope 4.4 progress is good

(this is for future reference)
the Reason why our phones on the stock roms is the same reason why windows slows down
error codes build up and one way to fix half of it is to wipe your cache, (one advantage of apple IOS, does not generate error codes and thus can last a straight 2 months of constant running)
AOSP /CM10/11 are much cleaner then stock and will take alot more time to slow down, and the same goes with Stock ICS, it will slow down a bit but no more then that
GB was about the best, it was perfectly coded , no errors
JB was coded by Sony DEV team B and team B is the ones to F***ed up almost everything they have touched
although Xperia Z run almost the exact same firmware as xperia s it got messed up when they ported it
its why i discontinued my rom, i couldent fix alot of the errors that my self and sony had caused

[Q] Warranty is up, time to unlock and install a custom rom+kernel. Suggestions?

I'm using stock .96 on my Xperia S, and I'm pretty satisfied with it. I installed the new Home and Walkman, rooted, and for me it's pretty much perfect already.
Since my warranty is up, I want to improve the phone to the max with a custom rom and kernel, but there are a lot of those on here, and I don't really have time to test them all.
Which one do you guys think is faster than stock and with more features and the least amount of bugs (or no bugs at all)?
Thanks in advance.

none,if i say seriously.i was like u but tried almost all roms.all are good and have different advantages but u use ur phone for camera,video and for heavy use like me,dont move to a custom rom for sure.u can try them after making a cwm backup and restore if u dont like.cm10 for locked bootloaders have everything working with few negligible minor bugs

If you like pure stock then I would highly suggest ExistenZ. I am really enjoying it at the moment and has been running fine. I really enjoy my Ion and with the new themes and stuff I don't even want a new device lol. The camera is a issue and if you do try this rom I suggest you also flash advance stock camera before initial boot. The newer camera is cool but with so many bugs its kinda pointless.

Ok then, I've decided how to upgrade... I bought a Samsung Galaxy S4. Found a really good deal on a used one and decided to get it.
Gave my XPS to my father so he upgraded from his god awful Xperia Arc S on ICS (a phone so slow it's literally unusable).
Honestly, I vastly prefer the interface, looks, build, and screen of the Xperia S, but the Galaxy S4 is way faster and the screen is bigger (colors are unrealistic because of OLED, I preferred the screen on the Xperia S), camera is also much better. If I was richer I would have bought a brand new Z1 though.

[GT-I9195] Basic CyanogenMod questions

Dear person reading this,
I've recently received an S4 mini, specifically the I9195 and I immediately got annoyed by the stock firmware. The sounds, the look, you probably know it. Since I've been using CM11 on my I9001 for a nice while I was wondering what the status of CM11 on this phone is like?
On the CM website I've seen there are no stable releases yet, so are the nightlies useable on a day-to-day basis? In other words, would you recommend flashing CM11? Are there any features which won't work?
As for the process of flashing itself, I've found this thread which seems to provide a nice overview, so I'm guessing that shouldn't pose any problems.
My apologies if this thread is a bit noobish, I've been reading around a bit but couldn't really find a nice up-to-date overview
Thanks and regards,
Marshian

If you use your S4 mini for anything serious, CM11 is still way too full of bugs. That's gonna change sooner or later, but for now I'd let CM11 wait unless you just use your S4 mini as a toy.
Check the opening post of this thread for a (long) list of bugs in S4 CM11: http://forum.xda-developers.com/showthread.php?t=2558702
Until CM11 is done squashing bugs, the best ROM for S4 mini is a rooted stock ROM, debloated by freezing/removing all the junk that Samsung slapped on, and modded with Xposed.
For a list of what you can freeze/remove (with an explanation of what you freeze/remove): http://android.site666.info/indexapks.htm
Essential (imo) Xposed modules for S4: Downloads2SD, Pictures2SD, Wanam Xposed, XPrivacy, and XVolume.
If you have a KitKat (stock) ROM you'll need HandleExternalStorage too.
Essential app to get rid of annoying sounds: Ultimate Sound Control.

I'm using CM11 on my GT-I9195 and its the only phone I have. The bugs don't hinder everyday use (WhatsApp, chrome, phone calls, SMS) generally except for the odd nightly that causes bootloops or FCs. You can avoid that by waiting for someone to post in the discussion thread whether the latest nightly is bootable or causes any FCs.
As for flashing CM11, the guide you linked is good if you don't care for the warranty. Since you bought your phone recently its likely to have the KNOX flag which signifies whether the phone has been custom-flashed before and I'm most countries this KNOX flag, if tripped, will render your warranty void.
To check if you are on KNOX boot loader, boot into Download mode and see if there is any mention of KNOX.
If there is, there is a guide on how to not trip the KNOX flag while rooting.

IMHO any of KitKat's custom ROM is not mature enough. Still many things to implement for the developers, regardless of being stable or not. Though if better OS resource management is what you after than KitKat is unbeatable. After all, it was Google's intention.
However, any of the JB custom ROM variant are relatively stable and mature, despite some still has the 'beta' tag.
As for TouchWiz ROM, there's a limit to what you can do in terms of optimizing/de-bloat. Unless it a heavily modded TW based ROM. That my experience coming from S3.

Thanks for your input! (This also applies to everyone else who replied )
In terms of warranty, I don't have any anyway. Though it's a brand new phone, I got it as a prize from a competition so there's no way for me to go back to the store and prove I bought it there. Therefore, I don't mind triggering the KNOX-flag.
For now I'll stay away from CM11 then (though it runs really nicely on my S+), but would it be a better idea to mod the stock ROM until it stops sucking or flash CM10.2 (or another version?) on there? It looks like the bug-list for CM10.2 is quite small. Do you know of any features missing there?

I would recommend any custom ROM based on JB. There's no feature missing as I'm aware of. Personally I'm on SlimJB which I've modified a bit myself. KitKat simplay requires time to mature. Even at AOSP the swtich from davilk requires time. Just my two cents.

I am very happy sticking with the last stable 10.2. It is reliable, quick, and battery drain is minimal (I use Gravity Screen Pro but the main power savings come from using Cyanogens advanced wifi settings).
You can always backup everything and try out a CM11.

Looking for a lightweight stock based rom.

Hai. I'm back using my good old Xperia S, but the stock rom is pretty meh, especially coming from the glorious Z3. I'm looking for a rom to make the phone a bit more modern and smoother. What I'm looking for is a debloated stock rom with stock sony stuff updated to at least Xperia Z apps, especially the launcher and the toggles. I don't care about overclocking or barely working honami camera or any of that stuff, I want fully working stock based stuff.
I tried a bunch of roms like Nature or Experienz but they're awfully bloated and full of malfunctioning features.
Alternatively can you recommend a fully working fully stable version of Cyanogen or an AOSP based rom with no bugs and no missing features (I can sacrifice the FM radio)? Last time I tried Cyanogen for this device I was tearing my hair out because of day runing bugs (such as the phone hanging mid calls).
Also what's a no frills kernel that doesn't annoy me with awful edgy boot logos and has a working recovery with ability to mount USB mass storage?

I have tried Nature Xperia and removed a bunch of "features" and so far it's working pretty well and seems faster than stock.

Nature Xperia with most of the crapware removed worked pretty well for me. Thank the gods I'm back using my Z3 now, I remembered the Xperia S was pretty smooth and very usable, but either my standards changed or something went wrong with it, it's so slow and clunky I could barely use it without getting constantly frustrated.

Thanks for the reply Mark.
Is the Nature Xperia ROM a "Sony looking" one like the Z series phones?
I don't use the Xperia S as my primary phone and use it as a backup (I have the Z1 compact) and like you, I agree - the XS seems to now be incredibly slow and I am guessing it must be our standards of being used to a device with more RAM. The Xperia S really seems to be struggling and that's why I've been looking for a custom ROM but one which looks like a Sony ROM and behaves like one. The closest I've seen is at Xperia Overlay, which looks very impressive, but I am not paying for a ROM for a backup phone.
I guess the XS just cannot handle the sheer scale of modern apps. I remember when I had the Xperia X10 and to some extent, the Xperia S, apps used to be so small - I remember when Facebook used to be a few MB.
