The lag is there mainly it is due to ram not properly flushed
This can be fixed in developer option by limiting background process I limit to 2.

Other is due to bad CPU algorithem cause by making go battery last longer they set the CPU to very conservative and lag came from there.

You notice lag when running multitask like waze + what's app + fb app all running together.

You need to remember your phone only have 300 or so ram for user to use. Not a lot. Download some ram/memory cleaner do the trick

Overall the lag can be solved by widgets and apps and ICS bring so many benefitsto xperia go. Overall ICS is the way to go

So should i update officially? Isnt meddling with the developer settings void the warranty ?

As long you don't root the warranty stay

I suggest to go for ICS.

anyone care to share some videos on how good the performance with ICS ? been watching youtube and this is not very appealing. http://www.youtube.com/watch?v=WwH9hBIwOxs&feature=plcp .

To understand the issue with void of warranty:

http://developer.sonymobile.com/services/unlock-bootloader/
http://unlockbootloader.sonymobile.com/

Let's take on following three(3) Sony Mobiles points of view of the void of warranty

1) unlock the boot loader will void the warranty - if you do this, you will void your phone warranty. So, do not do it.
2) unlock the boot loader will remove DRM security keys - unique DRM keys are created for your phone. Unlocking it will permanently remove them. They won't be recovered by firmware update. Without DRM keys, your stock Sony multimedia players like Walkman app and Movies app will no longer play any DRM-locked media content.
3) unlock the boot loader will not give any root access - To gain a root access, you need to have a customized ROM that has been rooted. However, this statement is no longer valid. You can gain root access without even unlocking the bootloader and/or flashing a custom ROM via fastboot commands. This is made possible with a root script via ADB commands, busybox and su (Linux super user mode program). No fastboot commands are used at all. Busybox is needed to provide the system tools required to root the phone. A hacker named bin4ry has made this possible. See the link below...

To understand what ADB can do:

Will this new root method void the warranty? Well, no if we rely on Sony Mobiles insistence of unlocking the bootloader to void the warranty since the new method doesn't even unlock the bootloader or even flashing a custom rooted ROM.

If there is a failure in this root method, you can still use SEUS/Sony PC Companion to update to the stock firmware without any trouble which it will unroot your phone (Repair option). Please, do a backup properly before proceed.

Anyway, I will put a disclaimer on this since Sony Mobile hasn't provide any news regarding this new root method.

**Update**



The phrase "Modification and adjustment" is too broad in the meaning. Do we consider installing an app as an act of modification/adjustment to the phone?

Note: how to show it unmodified without unlocking the bootloader? Revert to its stock firmware. But how? Using Flashtool in root mode:
1) Use the new root method to gain root access without unlocking the bootloader
2) Use Flashtool to flash the stock firmware

You phone will be good as new with unmodified stock without unlocking its bootloader

great information. you have already updated your phone to ICS, am I correct? How is the performance running on default clockspeed (200mhz if I'm not mistaken) ?

Great! No more obvious lags unlike before the new root method.

About the clockspeed issue in ICS, I know it from somewhere but I dont know how to verify it. What I can see that the phone is now clocked at 1000MHz rather than 200MHz based on the AndroSensor app in its device info section.

does tweaking with the developer settings solve the lag? not really looking into rooting my phone since it's still quite new.

If you are afraid of the advanced approach via the developer option (root or whatever) when you have a lag issue with your ICS update, try the repair option on SEUS/Sony PC Companion to resolve the lag issue. Possibly, it will work. Always make a backup before any update/repair. Disable any antivirus app before any update/repair.

great feedback. is it possible for me to downgrade it back to GB? I heard that Sony Center do provide the service to downgrade, do they charge for this service?

I don't know. But, I tend to agree that a fee may be charged upon the service (nothing is free nowadays) depending on the warranty has expired or not.

Give and take the new ics is much more stable altgough after a while it lag a little but just reboot your phone will solve the lag so reboot your phone once a day will make your life less lag hahaha

Here is my video

I was upgrade ICS but im just use standard version 4.0.4. Can i install app into external memory card SDcard... I buy external memory card SDcard 16gb but disappointed because cannot install apps into it.

Thanks

nope still cannot

Judging from your video I can see its quite laggy and slow. Or the Live Wallpaper is making it laggy ? Does Sony has future plans to fix this problem that almost all official updated phones are facing with?

i just hope Sony will update to latest JB near future.

dont hope too much

The ICS update doesn't looks good from the video above IMHO.
Let me get this right, without rooting the phone, the phone will be clocked at 200Mhz and there is no way to change it back to 1Ghz?

You can tweak with the clockspeed by rooting.

Added on October 10, 2012, 4:40 pm I dont think JB will be on Go. The phone even lags a lil bit on ICS imagine how bad it'll run with JB.

part of my contribution as well on ICS update performance

sorry i can't give the best quality on the video capture though
