Just had a freeze on the latest build, funnily enough I was changing the animation speeds in Nova launcher. The phone froze for about 8 seconds then the status bar vanished and came back and the phone kicked me out and back to the lock screen.
[Galaxy S 4 i9505 Android Development] Formhault:
I know that specific change... it is from an older SlimKat build changelog (I check changelogs weekly :) ). It is irrelevant, as the bug still occurs today :)

Lol, 107%...

Here's an interestig thing. While charging, with KT kernel, the chipset didn't use to get as hot as it does now, with Alucard... and the charging speeds are the same... :confused:

Settings/security/advanced reboot/show always

When you long press power key you will see it. You can also set power menu to be called virtually anywhere you want settings/navigation/hardware buttons/back long press/power menu - for example ;)

Tip: I use the app 'quick boot' available on g play, which is great as it puts individual shortcuts in the shortcut list so you can put buttons in your power menu or wherever to go straight to recovery father then reboot then recovery.

Until recently I used xposed module gesture control to set 3 finger gesture swipe to left to reboot, 3 finger swipe to right to recovery ;)

[Galaxy S 4 i9505 Android Development] Jsilver73:
My experiment to get freeze free is going good, one complete cycle freeze free and now well into my second :victory:

Not sure if it was an xposed module that was conflicting or switching to ART (ART definitely gives an edge to performance IMO) or maybe both that works with my set up.

I guess the next test will be to switch back to xposed and add modules back one at a time.

Although I can honestly say I'm not missing xposed anyway because this ROM is so full featured anyway and I like ART, and prefer stability (freeze free) :cowboy:
[Galaxy S 4 i9505 Android Development] kofe:
I have a hunch that it's xposed's fault. I am on dalvik without xposed, and i haven't experienced any freeze so far.

[MENTION=5528810]Jimsilver73[/MENTION]

I used ART before, but after you wrote yesterday you see the boost after switching to art I disabled my xposed framework and switched to art also .... must say that my phone was burning during the transition .... i ould say maybe 80°C +

But

I really see the performance boost - if this is just placebo then it is the best placebo ever :)
[Galaxy S 4 i9505 Android Development] kantjer:
Tempting, I must admit I have never even tried it.
[Galaxy S 4 i9505 Android Development] s3icc0:
few observations ART on 4.4.2 and ART on 4.4.4 r2 & ART vs dalvik

- 4.4.2 ART took much longer to boot up the phone, with 4.4.4 ART I see almost no difference to dalvik

- 4.4.2 ART was really battery conserving (like 10-30% more life) - I am sure that there will be immediate effect of ART on 4.4.4 for my battery life

- When on ART apps are really openning faster - nothing big but it is noticeable

- When on ART the Slim recents reacts maybe 50-100% faster

dalvik is awful word in the other hand ART sounds like Picassa's paint :)

loss of the xposed tweaks hurts, but not too much ... I can lie without - and maybe one day there will be ART compatible version
[Galaxy S 4 i9505 Android Development] kantjer:
Thanks for this overview, specially the boot time is/was worrying me.

I flash so much ROM versions, having to go through a long initial boot is not something I'm looking forward to.
[Galaxy S 4 i9505 Android Development] kantjer:
If you want to have the full picture there is a separate git for the Ramdisk.

Alucard's original and mine (used to build the kernel for SSK)
[Galaxy S 4 i9505 Android Development] kantjer:
It never worked, it's a "low priority" Slim Issue. But since this isn't an official SlimKat we don't use it anyhow.
[Galaxy S 4 i9505 Android Development] s3icc0:
Maybe good to notice in first post - that this ROM does not and never will use the OTA - is there a way u can disable OTA in the ROM build?
[Galaxy S 4 i9505 Android Development] kantjer:
Or even better, when I'm really adventures, make it work for SSK
[Galaxy S 4 i9505 Android Development] wonsky21:
I have a question: when I'm on art and choose clear dalvik cache from recovery - what will happen? :)

GT-I9505 | SlimSaberKat 4.4.4 jflte by kantjer
[Galaxy S 4 i9505 Android Development] HaTrED_:
And makes perfect sense... should have i thought a little bit to realize that! :o
[Galaxy S 4 i9505 Android Development] __NBH__:
I don't know how you get such a short boot on art, when mine rebuilds the cache for apps it takes ages, about 6 or 7 mins for 250 apps and the phone gets really hot and easily uses 10% of e battery. Dalvik is really quick, literally less than 2 mins.
[Galaxy S 4 i9505 Android Development] kantjer:
I guess that you have to go through that 6-7 minute and 10% battery draining process after every ROM flash?

So much for ART being more battery friendly.
[Galaxy S 4 i9505 Android Development] John_wba:
Not true, I've been on art for 2 months. Only the very first boot will take longer than normal (maybe 2 or 3 minutes),after that other boots are normal, for me anyway :)
[Galaxy S 4 i9505 Android Development] Greggd:
Exactly. It's just the first boot

.
[Galaxy S 4 i9505 Android Development] __NBH__:
Booting normally is fast but when you flash a ROM and it rebuilds the cache for apps it takes a long time, if you are wiping cache and system for ROM flashing it will take a long time compared to dalvik. I would set up in dalvik and once you are happy switch the run time.

[Galaxy S 4 i9505 Android Development] FlanjeUK:
ART since KitKat in December... Well worth the one long boot after each ROM update ;)
[Galaxy S 4 i9505 Android Development] kantjer:
I have added the "Remove 5sec Delay To Open Apps After Pressing Home Button" patch to the ROM.

Now I need a tester ;)
[Galaxy S 4 i9505 Android Development] kantjer:
Now this is getting confusing. Will I get the longer boot only once after making the transition or after every ROM flash (as I expect it to be)

I know I wont get it at every boot, although I think >50% of my boots are after a ROM flash :p

I can live with a boot of 2-3 minutes after a flash but I have also seen reports talking about 10-20 minutes :eek:
[Galaxy S 4 i9505 Android Development] Bejda:
The swipestarter app Jimsilver mentioned seems a good test,i could reproduce it but not with swipepad the "swipe from hotspot" app that i usually use.

It really took about 5 seconds to launch the linked activity (was browser for me,dolphin) after you push home button>home screen.
[Galaxy S 4 i9505 Android Development] FlanjeUK:
Wipe dalvik = long boot, it takes me no more than 3-4 mins (but I only have 86 apps to "optimise")
[Galaxy S 4 i9505 Android Development] aleksik:
Boot takes longer after every ROM flash. How long it takes depends on the number of apps you have installed. There is no point in flash the ROM with dalvik and after that change to ART as the transition needs the apps cache to be rebuilt anyway. It's totally worth the waiting for couple of minutes! :)

[Galaxy S 4 i9505 Android Development] kofe:
I have over 150 apps, and it takes about 10 minutes to boot... It sucks from this point of view. I also don't use art any more because the stock camera has an annoying bug since forever, the one that focus mode is stuck on continuous, and snap camera doesn't work on art...
[Galaxy S 4 i9505 Android Development] coyttl:
Re - The Art -

When dirty flashing, Art does NOT have to rebuild it's cache, UNLESS you Wipe Davlik during the flash process - then it will have to rebuild all the app code. Otherwise, it will only rebuild new (or updated) APKs in the new ROM that was flashed. (i.e. Going from 7/17 build to 7/22 build, three APKs were updated, only three need to be refreshed in cache.) This means also that installing or updating new APKs, eitehr side-loading or from the Play Store also take longer..!

Normal reboots take no extra time, and seemed faster on my S4, even.

On SSK (maybe v4.4.4) I can't use Art, since it breaks my debugging from Eclipse for some reason. But I used to use it a lot back before I found SSK. :)
[Galaxy S 4 i9505 Android Development] kantjer:
Yes, running it myself (see sig)
[Galaxy S 4 i9505 Android Development] John_wba:
I just tested without the patch and apps opened with no delay. Is it only a certain circumstance that there would be a delay?
[Galaxy S 4 i9505 Android Development] kantjer:
Correct, I need a tester that can simulate the delay.
[Galaxy S 4 i9505 Android Development] ParkerParker:
OT [emoji16]I've been using art ever since it became stable, months ago. There have been times that I would go back to dalv to play around with what I thought were interesting modules, only to return to art. The speed increase (opening apps) , the fluidity and the increased battery are all reasons I've continued to primarily only use art, if you haven't ever tried it I would diff recommend.. The only downside as mentioned earlier is the initial boot times contingent of the users apps and the ability to use Xposed (for the time being) .. This ROM w/ art is completely flawless
[Galaxy S 4 i9505 Android Development] Greggd:
What he ^----- said.
[Galaxy S 4 i9505 Android Development] Jsilver73:
I'll test :D

Can simulate the delay all day long lol

I saw your post on the stop switch delay thread last night and wondered how long it would take for you to change that line of code, didn't like to ask though ;)

2nd day freeze free with ART :victory::victory:

When KK was first ported to work on s2 (November 2013) I got very excited about ART and started a discussion thread herehere ;)

I created a poll at the same time and currently out of 99 voters almost 90% report performance boost whilst using it.

I would be delighted to see members from this thread go and share their experience there and also participate in the vote :)
[Galaxy S 4 i9505 Android Development] kantjer:
I will PM you later.
[Galaxy S 4 i9505 Android Development] Jsilver73:
Grrrrr!

Just experienced a 3 second freeze, linked to brief system ui insanity (bag bar and status bar disappear then reset)

Perhaps I'm looking for perfection that just doesn't exist?

Also had an incoming call earlier and in call ui fc'd. Haven't seen that for a while.

All that being said this ROM is running lovely :)
[Galaxy S 4 i9505 Android Development] wonsky21:
I must admit, I'm temted to try ART after so many good reports :)
[Galaxy S 4 i9505 Android Development] Bejda:
Actually i was wrong,it's totally reproducible with Swipepad app also.

I've read again the dedicated module post lol and context is: If an activity tries launch another activity right after you pressed the (standard,not remapped or whatever) home>home screen button you get the 5 secds delay..and sure it's reproducible with Swipepad also,sorry:o

Swipestarter was trying to launch the dolphin browser activity directly while swipepad launches its own overlay then activities choice (giving the *** is starting pop-up if launched within 5 secds).

That swipepad behavior hit my face again right after i've read again the post.

Why not implement patch anyway and see if it changes something to apps we're usually running? :)
[Galaxy S 4 i9505 Android Development] aleksik:
Go for it, you won't regret! :)

I love the fact that you strive for perfection and if something doesn't work, even if you don't use it yourself, that you try and fix it or if you can't do it yourself you get it fixed by asking somebody that can. It's the best support of any ROM I have ever used. Thank you :) its a pleasure using your ROM.
[Galaxy S 4 i9505 Android Development] UniqueFreak:
This ROM has finally cured my serial flashing! These latest additions have just made it an amazing piece of work and you should be so proud
[Galaxy S 4 i9505 Android Development] brizey:
I'm using it. It's always persnickety when I first install it no matter what the ROM. I usually restore it, let it fix the paths, then reboot and it works fine from then on out.

I stated using it heavily when I was experimenting with f2fs so I could wipe /data with impunity.
[Galaxy S 4 i9505 Android Development] d0nald01:

Does F2FS work with this Rom?
[Galaxy S 4 i9505 Android Development] __NBH__:
Works fine as long as you convert the ROM before flashing if you want it to use F2FS.
[Galaxy S 4 i9505 Android Development] Jsilver73:
May I ask what you hope to gain by converting to f2fs? Of it's performance, well I noticed none whatsoever, if its battery, nope - no improvement there I'm afraid.

Only thing I did find with f2fs is a major ball ache jumping through the hours to get it working and keep it working on each new installed system :eek:
[Galaxy S 4 i9505 Android Development] kantjer:
I made the transition a few hours ago. First impression is that everting feels a bit snappier.
[Galaxy S 4 i9505 Android Development] fedef12evo:
hello is possible for you to share alucard kernel that comes with the rom? i saw an update on kernel and i wanna try, you can pm me if you cant share here :good:
[Galaxy S 4 i9505 Android Development] wonsky21:
I must do something wrong then. For me it is disaster. After switch to Art:

First boot: about ten minutes, phone got hot as hell, all apps updated, after boot lot of fc's (nova, some system apps, can't remember all, there was so many of them), finally my phone rebooted itself

second boot: half of my apps updated (again), after boot some more fc's (different apps than first time), phone rebooted itself (again)

third boot: half of my apps updated (AGAIN), after reboot nova lost all settings. At this point my patience reached to an end. Restored nandroid backup...

So, myabe someone can advise me, what is the proper way to switch to art? I've just uninstalled Xposed, and switch to art runtime in Settings/developer options...
[Galaxy S 4 i9505 Android Development] Jsilver73:
Yep - that's been my experience since the beginning, and that's what it says on the tin, in a nutshell ART compiles the code for apks into something close to native so it can open them quicker and more efficiently.

Bearing in mind this is still WIP on OK I wonder what it's going to be like when officially released on android L :cyclops:
[Galaxy S 4 i9505 Android Development] kantjer:
The only thing I did was uninstalling the binary using the xposed installer app, switched to ART and rebooted.
[Galaxy S 4 i9505 Android Development] wonsky21:
I did exactly the same...
[Galaxy S 4 i9505 Android Development] s3icc0:
I would say your problems could be kernel related. Did you undervolt or change kernel thermal settings? My phone gets really hot during the transition (250+apps) and only problem I got was stuck at boot logo during first reboot
[Galaxy S 4 i9505 Android Development] russ18uk:
Well I tried ART on the s2 and didn't notice much difference. On the s4 applications open more responsively. Perhaps that's down to CPU architecture.

Anyways... first boot is a little slower and once loaded many widgets are still adapting so that increases the switchover duration as well.

Other than that, I'll just have to play around with the phone and hope some apps aren't incompatible.

Doesn't look like I'll be keeping this phone for much longer as I keep putting the s5 in the basket but am hesitant when looking at the 805 and Tegra k1. Would love to see a k1 smartphone announced before I pull the trigger and suffer buyer's regret.
[Galaxy S 4 i9505 Android Development] wonsky21:
I use kantjer's undervolted profile. But it is not high temp that bothers me. I wonder how I got so many fc's and why my apps are updated over and over after each reboot. Obviously it is something on my side. The others switched to Art without any problems...
[Galaxy S 4 i9505 Android Development] russ18uk:
Btw I uninstalled all xposed apps, removed framework then uninstalled xposed and switched to art
[Galaxy S 4 i9505 Android Development] s3icc0:
I meant it like cause of the heat or undervolting some transition is unfinished.. if I will be you I will give it several reboots or even a reflash of rom and gapps
[Galaxy S 4 i9505 Android Development] UniqueFreak:
That's exactly what I did too and running on art is the best choice imo
[Galaxy S 4 i9505 Android Development] s3icc0:
I did it same as kantjer just uninstall the framework via xposed installer so on case I will switch back to dalvik I will still have all my modules with settings easily
[Galaxy S 4 i9505 Android Development] kantjer:
Did you remove the xposed binary before removing the xposed installer app?

My first boot also took about 10 minutes all together. But my phone wasn't exceptionally warm during booting.

I had it connected to a charge during the initial boot.

I removed the xposed installer app and all modules after the switch to ART and finding everything was running fine.

No a single FC or data loss. I only needed to switch off some app notification now I don't have Notify clean any more.
[Galaxy S 4 i9505 Android Development] Jsilver73:
That shouldn't happen, never has happened to me. Did you actually uninstall xposed framework before you uninstalled the xposed app?

I would go back to your last good nandroid and try again if I were you wonksy ;)
[Galaxy S 4 i9505 Android Development] wonsky21:
I think I'll format system partition and flash rom again, but without xposed binary. Then I'll try again.
[Galaxy S 4 i9505 Android Development] kantjer:
I think I finally found why transparency wasn't working for you, it happened to me earlier today after switching to ART.

After removing Xposed (including a module making system ui background transparent) I also faced the issue with a solid black notification background even when having transparency set to 100%.

I then realised that I had a wallpaper set that came as part of an icon theme app. After switching to a wallpaper based on a regular png transparency is working again.
[Galaxy S 4 i9505 Android Development] munichsfinest:
Your problems sound very familiar to me. On the last release of ssk I switched to ART and got exactly the same issues. On former releases and, in earlier times, other ROMs, it worked just fine...
[Galaxy S 4 i9505 Android Development] brizey:
Three or four extra minutes max. Converting the ROM in KTweaker takes about two minutes, then change the settings in KT's TWRP, maybe 15 seconds. Then format data to f2fs, maybe 20 seconds? Then do the wipes you were going to do anyway (system and cache) zero extra time. I guess maybe an extra 30 seconds to flash a compatible kernel. Done. I have never had it not work or noticed any issues that I could trace back to f2fs. I use foldermount to keep all my important stuff on the external card anyway. I don't trust that the no wipe odin restores will always work. I've been going back and forth between this and Dan's GE ROM lately, so I am on ext4 now, but I may go back to f2fs at some point. It's not zero effort, but is not hard and it works just fine.

I agree though that it doesn't have much impact on this device. But if all we cared about was expediency we would be on an Apple forum. You do it because you can, lol.

change log:

removed 5 second delay to open apps after pressing home button

SlimOTA working for SlimSaberKat, will work for every new release (no more stable and weekly differences)

ROM built with updated SaberMod 4.8.4 toolchain

Both ROM and kernel are in sync with the latest commits.

This is not a major release but mainly to test the OTA function.

You should see a screen like the one below, and if all goes well an update message when I announce the next release :fingers-crossed:
