For me dialer works fine. No lags. Only problem with dialer is the color of dialed numbers that are black and can't see them with low bightness. Also another thing is with the battery % number, sometimes goes bold like the screenshot below and can't realy understand the number.

Which minfree values? I tried with the ones proposed by alwaysadeel but it doesn't work. It works with default ones.
[Sony Xperia P, U, Sola, Go] _ViBe_:
I didn't change minfree values. Just the default values from rom. ;)
[Sony Xperia P, U, Sola, Go] Mons1990:
And how did you solved back button and keyboard fc issues?
[Sony Xperia P, U, Sola, Go] _ViBe_:
Keyboard and back button still fc. No solution yet. I haven't tried different minfree yet in this build. i'll try and if i see reduced fc i will post.
[Sony Xperia P, U, Sola, Go] itachilinux:
anyway, i wondering if sola has CandyKat ROM.

SlimKat is nice but i can't use Halo and LockMax mods from CandyKat...

otherwise, lockscreen button, glowdots and battery/wifi/sgnal icon can be flashed straightly from Candykat :D

[Sony Xperia P, U, Sola, Go] Mons1990:
Thank you very much. I've also changed governor in SmartassV2+sio to save battery. It can be the reason of the freeze?
[Sony Xperia P, U, Sola, Go] _ViBe_:
Can't really tell you if this was the problem because in SlimKat i have never changed governors. In CarbonKK I remember that by changing governors ROM was performing better or worse depending on which combination you select. If you are not bored try searching the CarbonKK thread in comments about suggested governors by users. One combination was working very well for me in CarbonKK.

Btw battery for me lasts about a day on SlimKat, which I believe is good. Think about it. Now cellphones are multimedia machines. Think about wi-fi, camera, bluetooth, touch screens, bigger screens. All these things need energy to work. You got a smartphone, not a Nokia 6310 which with one charge lasts 6 days. :P You know what i mean.

some mod can''t be used (like halo and lockmax) cause slimkat doesn't have it.
[Sony Xperia P, U, Sola, Go] alwaysadeel:
yes, thats because slim framework is different :)
[Sony Xperia P, U, Sola, Go] itachilinux:
so then, that why i want CandyKat ROM for sola :))

otherwise these mods is works for Slimkat (except halo and lockmax).

Oh, off course also lock keyboard!

Otherwise, as i already said, this ROM is awesome!!

I've just set al preferences and now my phone works like charme: no back button & keyboard issues and very buttery smooth experience.

Minor issues i encountered:

From Settings > App > All selecting one app the Clear Cache function doesn't work

Problems in video playback

I have to say that 1 year after the release of FXP216 CM9 this ROM finally overtakes it in performance and stability and has become

the best ultimate ROM

for Sola. Lots of thanks at all the people worked on this project. In particular I want to thank:

[MENTION=5143053]alwaysadeel[/MENTION] that bring us this magnific work

[MENTION=4120742]munjeni[/MENTION] that worked on our phone from before I bought it and on his work are based almost all the project we see everyday here

But.. I'm i the only one with a terrible lag in incoming call? Like 2-3 seconds and more of black screen while ringing?

Inviato dal mio Xperia Sola utilizzando Tapatalk
[Sony Xperia P, U, Sola, Go] _ViBe_:
I just used this tutorial suggested by [MENTION=5270508]Mons1990[/MENTION] in his last post. Well I have to say that living SlimKat with default settings ROM was performing very smooth. No incoming call lags but back button and keyboard fc. Now after using the guide i have no back button and keyboard fc yet but I see the incoming call lag as you say. I can hear the ringtone but the screen remains black for about 2-3 secs. After these secs the screen turns on and everything is ok. for me it's not a big problem. I can live with that. But it would be awesome if could be reduced. Maybe playing around with governors could decrease the lag. Well, by the time i am writing this post i changed governor from SmartAss V2 to Lionheart and leaved I/O to sio. Guess what, no incoming call lags. :D awesome. This ROM becomes better and better! :p

So from the tutorial is did these things:

¤¤¤ First of all, download Performance Control by [MENTION=4674443]h0rn3t[/MENTION] (Performance Control) and install it.

¤¤¤ Go to CPU Settings on Performance Control (If you're on CyanogenMod ->Go to settings>performance.)

-set "SmartAssV2" as Governor

-set "sio" as IO Sheduler

-Tick "Set on boot"

(As i said before i just changed SmartAss V2 to Lionheart!!!)

¤¤¤ On AOSX or AOSP :

Go to Perfomance Control>Memory Settings and enable KSM.

¤¤¤ Go to memory Settings on Performance Control

Set

-6

-8

-16

-20

-22

-24

-Check "Set on boot"

¤¤¤ Regularly, go on Performance Control>Tools

- Press Optimize Databases

- Clean residual files

Now reboot the phone. Each time you reboot the phone you have to wait about 3-5 minutes to load everything and run smoothly! :)

The rom runs very well I can say!

Video playback on Youtube app is flawless but video playback on FB app still hangs the phone. It doesn't reboot but it crashes all services, Wi-Fi, GSM, Nova Launcher etc. So it needs manual reboot.

Also I want to ask [MENTION=5143053]alwaysadeel[/MENTION] if ART is supported by this build because if you read the tutorial it says to change from Dalvik to ART. Is it safe? Because I had tried that on CarbonKK months ago and I just ended up with an unbootable ROM.

Also I have to say thanks to [MENTION=5270508]Mons1990[/MENTION] for suggesting the tut. :D
[Sony Xperia P, U, Sola, Go] Mons1990:
I see you found yourself the recipe. I confirm that lionheart has no call lag while smartassv2 has, but I think I can deal with it. Now I want to try also ondemand, minmax and lulzactive

So after SlimKAT 5.8 was released this morning I started messing around with some tweaks to determine which is better. Here are the results:

Stock SlimKat 5.8:

AnTutu: 9040

AnTutu X: 9384

Video Playback: On FB app phone reboots.

FC: Back button and keyboard

Lags: Sometimes it have 3 secs lag for incoming calls. A bit laggy when scrolling and loading things but not easily noticable.

SlimKat 5.8 (Pimp My Rom):

AnTutu: 8543

AnTutu X: 9319

Video Playback: On FB app phone reboots after a while.

FC: Back button, Keyboard

Lags: 3-5 secs incoming calls lag. Much more laggy than stock SlimKat.

Comments: I didn't see any improvements from stock SlimKat unfortunatelly.

SlimKat 5.8 (PurePerformances™X):

AnTutu: 8632

AnTutu X:9820

Video Playback: On FB app SystemUI fc and phone reboots.

FC: Back button, keyboard

Lags: A bit laggy on system animations and scrolling.

Comments: I have to say that phone responds much faster than stock SlimKat but there are a bit animation lags.

SlimKat 5.8 (Tweaks by [MENTION=5343447]Angristan[/MENTION] using Dalvik instead of ART and Lionheart with row instead of SmartAss V2 with sio):

AnTutu: 9330

AnTutu X: 9408

Video Playback: On FB app plays 2 videos of 10 secs each and then if you try bigger videos, reboots the phone.

FC: None

Lags: None

Comments: Unfortunatelly ART didn't worked as it supposed to. I had a few reboots when trying to restore apps with Titanium and an fc of Google services when opened contacts for first time. After 4-5 reboots while resotring I reformated my phone and just used Dalvik. Phone responds immediately. Animations and scroll is very smooth. Obviously the best tweak!

Also I am using Greenify to hibernate background apps and Titanium Backup to restore installed apps. Not the accounts and other system data. Just user apps with their data. Using Minimal Gapps 4.4.3

Again, a very big THANK YOU to [MENTION=5143053]alwaysadeel[/MENTION] for bringing this awesome Rom to our devices! This is trully the best Rom for XSola! The smoothest and most beautiful one! Also I have to thank [MENTION=5270508]Mons1990[/MENTION] for suggesting me the tweaks! ;)

Well, thank you for helping me run ART! Here are some results from my test:

First of all I did this procedure (after each reboot I left phone setle down for ~5 mins)[p.s. I never use Clean Master. I think it just bloats the phone. Just Greenify]:

Fresh Install

Setup account

Dev Options> Runtime : ART >Reboot

Install Performace Control

Setup tweaks

Setup SlimKat UI

Reboot

Open Google Play>download the rest of Google Play services

Reboot

Install Apps

Greenify apps

Reboot

Start Benchmarks

RESULTS:

SlimKat 5.8 (Tweaks by [MENTION=5343447]Angristan[/MENTION] using ART and Lionheart with row):

AnTutu: 9356

AnTutu X: 10118

Video Playback: On FB while playing, Google Play services fc two times and when video is finished FB app fc and phone reboots after a while and stays at boot animation.

FC: On video playback on FB app. Google contacts can't sync. Keyboard, back button, Random Google Playstore fc.

Lags: None

Comments: I was impressed by the Antutu results! But there are still the known fcs. Runs very fast, seriously, but I won't keep it. Also I tried with Smartass V2 + sio but didn't see improvement, just added the 5 secs lag when screen is off for incoming calls. Scroll and animations are smooth, video playback on Youtube was very smooth too. Overall ART is very fast but needs improvements to be more compatible with apps.

Back to Daaaaalviiiik!!! :cool:
[Sony Xperia P, U, Sola, Go] Mons1990:
After some other try I figured out that Lionheart is not better then others, it's smartassV2 that works very bad on this ROM. So I looked for something different, and you should try the combination hotplug+sio, it makes the whole system a little less smooth but it drain battery much slower then Lionheart and I don't notice call lag.

[MENTION=5682597]_ViBe_[/MENTION] can you make some test with it? We have results of all your other tests and can be useful to see this compared with others in the same system.

Are you sure that it's WiFi that is draining your battery? My phone is running for 9.5 h on battery now and still has 90% charge left. It was lying idly on my table for most of the day, but WiFi was on all the time (WiFi network connected with strong signal).

I'm testing ART at the moment (seems to be a little less smooth than Dalvik but no issues so far). Battery life is not much different than with Dalvik.

No special tuning applied. CPU freq min/max 200/1000 MHz, governor currently smartassv2, scheduler sio, network mode is 3G preferred, location is off unless I really need it, sync is always on.

For me the battery drain of the ROM itself is rather low, if I don't run any apps that load the phone heavily like navigation, video playing etc.

Maybe your phone's battery is bad, has not much capacity left?
[Sony Xperia P, U, Sola, Go] _ViBe_:
Ehmmm.. If I left the phone just siting on table surely I can do 9h and still have 90%. But I use my phone you know.... Can you give a screenshot of your battery stats from 100% to 1%... Ty

Here are my screenshots of battery usage with Lionheart and Row from 100% to 1%

I know it is bad but I use the phone much.

Also I saw that not restarting after 2days continiously I start having keyboard fc sometines. So reboot every 24h is surely needed...

[Sony Xperia P, U, Sola, Go] Mons1990:
I don't think so cause I always have taken care about it (only a few complete discharge and never left hours under charge when full), but it can be.

I also will post it with hotplug+sio, but remember that we flashed ROM from short time, I did a battery calibration cycle this night after setting hotplug but results are still inaccurate.

P.S. Who deleted my post with Bin Laden could also send me a PM explaining why, this is unpolite! Also because there were other serious things in that post! But after 3 unfair infractions and an unfair suspension I've understood that the moderation of this forum leaves much to be desired...
[Sony Xperia P, U, Sola, Go] mstreibe:
Yes of course I also USE my phone :) , but only very little when I'm sitting on my desk all day with a computer and a landline phone right in front of me.

Will do when it is empty.

I think my figure (90% after 9h) was a good example for showing the battery usage of the ROM itself. I mean you can't blame the ROM if it's the apps that are eating up your battery, unless you have a major difference to other ROMs with the same workload.

Not over here, but it may again be related to my lower phone usage. But I also switched back to lionheart after reading that smartassv2 may be responsible for delays on incoming calls, which I had here too.

My battery stats were inaccurate with previous ROMs. It showed battery empty but when I plugged it in it was back up to 70% within a few min, or showed much higher charge after a reboot. But currently it seems better.
[Sony Xperia P, U, Sola, Go] _ViBe_:
Yes but use means an average usage of phone. Means using apps, wifi, make calls etc.... Again, this is my opinion. Maybe I am wrong...

But I don't blame the Rom I just try to figure out which governon suits better for an average use. ;)

As engineer this debate is my everyday bread. Customers complain about car manufacturer cause it says the car drains 3,5lt/100km and they say that they can make only 5lt/100km; so manifacturer says that if you drive bad is not an engine's fault.

We're not talking about wrong results but different methods to obtain them. Just consider that they both are correct but not comparable. This is the reason for which I asked [MENTION=5682597]_ViBe_[/MENTION] to test hotplug: his software configuration allows us to make a comparison.
