[Sony Xperia S, Acro S, Ion] Fanta_BH:
what I did so far

No I do not reboot device , only if it is needed to solve problems , other than that it working months without reboot.

After got in to problem with com.android.phone stoped msg , and after forced reboot problem with no sim card, I fleshed GB stock rom with clearing all data and it solved problem with sim card, everything was fine, than flashed NL ICS rom , after few hours of working got in to some minor trouble but biggest flaw was market msg for wisepilot (as it was not included in rom) it says not available for your country. And I love wisepilot it cover my country very well. Better than some other I tried. So decided to drop NL and taken CZ rom, flashed it last night and so far it working flawless, only minor bug I think it is caused by avast not by rom itself or phone, playing bubble shoot a lot , and every session of play has one 30 sec period of very slow and choppy working in game or totaly no response from game, but found that simple pressing few times on pause button afte 10-15 sec getting to pause in game, and than resume and everything is fine. So With cz rom started to taking all apps back and setup, so go installed go launcher and guess what, there is no leak in memory like before, if I chose go launcher than only go launcher working without xperia launcher in memory, if I switch back to xperia launcher , go launcher go away. Only thing I did not install and will not for sure, is LBE privacy guard. So later afternoon decided finally to root my phone again, since lost root with all flashing all Roms above dunno which one caused lose of root but I suppose it is stock GB rom. Roted it again on same easy way , prerooted image of CH ICS rom. Was wondering what going to happen since flashing prerooted image of CH rom while on phone is CZ rom, and somewhere I remember is note be sure u have installed CH stock ics rom before using CH prerooted image. As I got it it do not overwrite everything on phone it is just kernel and some other dunno but what I know , rooting finished fine, no problems , well still got problem with how to start flashing as instruction given here not working for me, so did it by flash tool but by using slightly different way.

So far didnt jump in to any problem , still using avast as way of protecting my phone , and not sure if I will keep it or replace it with some other, possible norton antivirus, as no much use of any firewall protection as I run in to many troubles by using firewall before.

So here are few things what I noticed.

Before on rooted ICS CH rom :

LBE gaurd - after a month or so , bug with memory leaking, it was taking up to 300 MB or RAM

Firewall (in my case used LBE) - by blocking many app's including many system apps got int o many problems , most was causing unresponsive phone for minute or two than phone continue to work fine. AS I am IT expert but mainly for Microsoft products, I know how windows become unresponsive when some background apps cant comunicate over internet because its blocked by firewall or no connection at all, so got same idea for android phone and problems with unresponsive phone for minute or two and than work like nothing happen. First removed block, I man allowed almost all system apps and some other apps. After that there was almost no more unresponsive moments.

Have runing in problems with apps crushing very ofthen, apps which was crushing was GO contact , Go phone, some apps for tracking 3g usage, and few more but dont remember which one.

Problem with whatever launcher I install it going to leak memory together with launcher which is in use. only solution for this is to keep only one launcher installed, but was so afraid to uninstall default xperia launcher.

As well one problem bothered me all the time, one day MMS working fine, another day it not working, one day stock sms app can send MMs while go sms fail in sending MMS and after a while could not send MMS at all.

Today I am on ICS CZ rom mixed with prerooted CH image.

So far everything working so fine that I can't believe.

again using go launcher but this time from time I activated it xperia launcher gone from memory totaly.

go contacts and other GO apps do not crushing anymore like before, I mean they not crushing at all.

After flashing prerooted image even buble shoot started to work without any problems

No lag, or chopy work or whatever, everything working smooth and fast.

before was getting some other apps to crush, now all apps I using working fine.

Did not check MMS will do tomorow.Don't using much of MMS service but it is nice to have it.

So I can confirm CZ rom working very well even I do not see big if any diference between CZ rom and CH rom I used before. Both coming with same set of preinstalled apps, even GB rom I used had same set of preinstalled apps so I assume they are all same just some minor changes for every country Like it was for NL rom, visepilot can not be used in ur country and u cant even install it on NL rom.

So time to go sleep , see ya again .

used it only once to receive minor update on gingerbread, and it did not erase anything. Did not used it for updating to ICS so have no idea what it will do in that case.

Well if use custom rom and update via flash tool yes u will lose personal data , contacts and so on , but backup curent one and after flashing be sure you are in range with WiFi u can use, after boot u will get in to quick setup , so press next , next till you dont get on screen with set wifi connection or something like that, connect your phone to WiFi and one of next screen will offer you to auto setup MMS/internet , so just press yes on question do you want to download mms/internet setting now and it will download it via WFi . At least I do like that all the time and I am in Bosnia on BH telecom so , they did relaise offical ICS but as I was on in that moment NL ICS rom, pc companion simply said to me u using unkonw software your phone could not be updated. So again I used flashtool and will do it on that way as I love to have rooted phone and dont want to lock BL again.

Yes I seen same like you , but mainly problems like yours was caused by protection apps on phone and as well some apps like to leak memory so get some nice task manager and take care about how much free memory u have , if run low , I would say below 50 MB you will get in those problems as android phone swapping data on external card same like PC doing with hard disk when there is no enough free RAM and when swapping it will lag like in your case. But still I did not find way to stop apps auto run in background without my knowledge and all apps on android do that from time to time. So Free RAM is sometimes problem with such behavior from all apps u have installed. Only way to keep my RAM free is control what apps u install and use, do not install anything you dont use or u dont need, use task manager to free memory but usualy it do not help almost at all as apps auto run again and again , but u can find with nice task manager how much ram which apps using, and I found some apps leaking memory badly. Such app was LBE guard and after I removed that one got my xperia working smoth again.

At my opinion , smartphone = garbage only because users can not fully control what apps doing in background, and you cant control at least not for free what apps will autostart and what will not.

without aditional cost , you can not own your mobile phone 100% , you can root it, you can remove everything , but whatever is installed on your phone it will work in background without your knowledge.
