shit yaar,,, m such a big fan of sony(ericsson) and its feels really sad to wite about cons bt still had to inorder to get better software update..
this is my third post in this thread and one was with pros and cons though cons were more then again i posted which were full of cons...
and now this is third one with lots of more bugs
let me tell u m Using Xperia NEo v and installed ICS after factory reseting my phone ....
got 200MB free memory on phone and always shows 140Mb free ram
so dont hav much app installed... and got 8GB class 6 memory card
-Compass not working even tried calibrating through service menu... so the google maps cant detect wich way m facing...
-wanted to watch youtube video in browser using HTML 5 support (as i dont wanted adobe flash) bt i was making my cell hang..
- so installed adobe flash and thought video plays.. bt it crashes a lot... even at 360p where earlier in GB 720P was running smooth without even crash... i preffer 480 to match my screen resoluting bt i can run even 480 as browser crashes lot... thanks to new youtube app which is optimised nw and is usable..
-browser crashes a lot more then two pages are opened ... and sometimes it hangs my cell for 30sec or so and then automatic restart
- even opera mobile gets hanged lots on ICS over xperia
-also obverved some issue with downloading large file of about 100 mb (was using wifi with 1mbps internet speed not shared with anyone else) but i never observed any drop in wifi connection as some complains and its perfect....
-also some bugs while using third party camera apps like camera 360 which is recommended by sony ericsson....
1-before ics update.... wifi worked better... but now.... too slow....
2-lagging while recording videos

After updating My Neo V to ICS 4.0.3 a week ago, I found the following Pros and Cons:
Pros:
Cons:
Kindly fix these bugs in the next 4.0.4 update.
Anyways we appreciate Sony for giving a timely update as per the schedule. However, the update comes with some bugs. Anyways, Good Work Sony. 
Please bring Multitasking to the fullest advantage in the next update. Please give us a new and sexy Music Player with Folder Wise music playing option.
Thanks
i personally think that there are more cons than pro after the ics update, quite dissapointed actually.
lets start with the pros, beautiful UI with more options to choose from in phone setting, and also much smoother browser experience. Photo gallery seem to load much much faster.
As for the cons...there are just too many but il leave a few important ones. firstly im very dissapointed with the lagging in games and doesnt regonise touches at times ( temple run, angry birds, even glow hockey??) of course its still playeble but its not the same gingerbread gaming experience anymore.
2nd problem is with the HD video recording, you will notice some slight lag for the first 1-4seconds during playback. only HD recording though, QVGA,VGA and the rest are all right.
So overall you will hear about laggy and here laggy there... im sure Sony can do a much better job, and hopping for a new update soon. If not might be switching to perhaps Samsung in the future.
TQ

Hi Johan,
First of all, thanks for bringing this discussion topic on the blog, I just update my Xperia Arc S with the new ICS system yesterday and I noticed there are many many bugs on this version by SONY, MANY BUGS!!! Like our fans’ comment above, the bugs are all what they said.
Here I re-state the bug from the top urgent issue to the low:
I really looking forward to see sony got the new version and non-bug ICS update. Thanks
This is my second post regarding ICS 4.0.3 on Neo V. I did a Repair of the ICS and followed by a factory reset. To be honest, my Neo V had got a fresh life after the repair.
Pros
Cons:
Really, doing a Repair after installing the fresh ICS does bring more changes to the phone. If anyone found your phone laggy, you can try this Repair. It works. 
Sony, we are expecting the 4.0.4 update from your side soon. Still Happy with the ICS...

Hi everyone, I’m from Philippines and updated my phone to ICS. Here’s my review:
PROs:
CONs:
Overall for me it’s good but I’m not well impressed. Looking forward to update 4.0.4 or might as well go back to stable GB for a while.
Thanks SONY.
Hi Henry,
I think i can help you solve many of the issues other than the LED, Low sound when unlocking, gaming and missing widget.
1st If you have not factory reset the phone or not repaired it (by connecting to PC companion) after updating please do that, it will make it more fast. The reason is usually when updating Sony use to format the phone removing all the data and then freshly install the new update, this time they have put it on top of the old one making it laggy and messy. When you reset or repair, it gets fresh and you will notice a huge speed boost.
2nd I suggest you root your device and get rid of many unwanted apps that runs in the back and slows your phone, with ICS you can root your Arc S with just 2 clicks without need to unlock the bootloader hence warrenty remains. You can unroot it any time by reparing the phone with PC companion.
By doing either one of the above or both you can get a huge improvement in speed and battery life. So two problems solved. (For your info i have Arc S and has done both the above and my phone is buttery smooth)
Next regaring the gallery and video player. I believe you are using the Xperia Gallery, please dont use it. It has got lots of bugs. Infact the first app i removed after rooting was Xperia Galllery. I suggest you use the default ICS gallery its smooth and video playback is really good. Or you can always install Mobo player (FREE) from paly store which has an awesome video playback and supports lots of formats.
Then about gaming i belive its not Sony's fault but the game developers have not made the games support ICS well. Give some time for the game developers to release updates to support ICS properly.
Thats all i guess.... wait then regarding camera in lockscreen i think its a really useful feature for me. 😉 So i cant think its useless.
Hope i helped you.
NOTE: If you wish to root or have any questions please ask ill help you out.
I'M SO ANGRY!
YOU destroyed my perfect ARC S! Last time when I updated my x10 to 2.3 I had the same feeling, but it did goed away in few days! But now I have the same feeling and it hasenät gone away! Had this upodate about month now?
Pros:
Updated UI, (some times its ugly, like this blue screen what looks like crap, like oure screen couldn't handle 16M colors!?!)
Better settings menu (more logic)
New lock screen (But where is the option to take camera button away?)
Cons:
REALLY LAGGY
App drawer open looks like crap
Everything looks like crap (smooth at craphics is gone)
SO SLOW
FORCE CLOSES (all apps force closes all the time)
App drawer changes app's orders in menu and in folders too
Laggy home screen, widgets lag and sometimes don't load
Camera sometimes doesn't save images to gallery
Writing text message is really awful now, it takes 3-5secs that you are able to write (keyboard doesn't take any presses for some time) It slows down this thing!
Phone is hotter so I think this consumes more processor power.
Phone reboots byself sometimes
Network issues (doesn't have singal sometimes)
My friend's Neo is much faster and looks better and smoother! AND know what? His phone vas 200e cheaper than my arc S and it is better!? SO wtf SONY!? Please update and fix these problems fast.
I always had been sonyericsson lover and fanboy but now I first time think that this can be my last sony mobile!
*tried to install update 3 times and same problems all the time so very very dissapointed...
Pros:
Better UI ,better battery and new features of ICS
Cons:
Verrrry laggy and slow
Old kernel 
my phone sometimes keeps vibarting by itself
Plz we want the new kernal and a faster UI , and if possible to add the Camera lunch from sleep feature like the NXT series to the 2011 line and the Original ICS keyboard beside the Xperia Keyboard
