while using the phone, u will experience no lag at all. the dual core processor really makes a super smooth experience using this phone. the only 'lag' is when u turn on the phone when its in sleep mode.. it takes a second or two for the screen to turn on. its the most annoying point of the phone for me. apart from that, there's nothing like wat u describe on the original galaxy S.

 

i've only had my phone for 3-4 days and i have experienced no lag or freezes, i am very impressed with the phone, a lot more than i expected to be.
although to be fair, i rooted it and flashed a custom kernal and rom within a day or so but even standard it was pretty flawless.
its a fantastic product

 

Nope.

The SGS2 is super snappy. It's one of the fastest devices I have ever used and in the three months I have had mine, there hasn't been a single occasion that I wanted it to be faster.

 

If you would like lag, then get the HTC Sensation with its 768 MB of RAM, compared to the 1GB of the SGSII.

In practice this means that the Sensation has around 180MB of RAM after boot up, with the RAM heavy Sense UI, whilst the SGSII comes in at around 450 MB (2.5 times more) at boot.

This is most noticeable on my colleagues Sensation after opening things like Gallery, browser, video's, when a lot more RAM stopping and swapping has to take place. Not a big lag admittedly... but noticeable.

This coupled with the difference in the CPU's/GPU's, gives the SGSII the edge in both performance and speed.

See here for a side-by-side spc's comparison:-

Hope this helps.

 

i would highly recommend it.
i was torn bitterly between the SGS2 and the Xperia Arc.
my previous phone was the X10 and i loved the feel of the Xperia phones, the build quality is very good and they look amazing.
i always thought the SGS2 looked and felt a little cheap when playing with them but i decided to go with that due to the Arc being a little older and probably replaced sooner with a newer model but i have no regrets now.
the SGS2 is the fastest Android device i've ever used and even the look and feel of it have grown on me so much that i think my previous Xperia is a little bulky feeling and i havent touched it since i got its replacement.

the SGS2 gets 5 stars from me and i was never a fan of Samsung phones previous to this one.

 

I'm so glad I waited for the S2 rather than buy the Sensation. No lag. Phone of the year in my opinion.

 

You will be shocked at the difference. It is amazing what the faster processor does for the general operation of the SG2.

 

No lag here with my SGS2. It's my first Android phone and I'm glad I chose it over the Experia Arc.

Its seriously quick!

 

To the original poster: I want to know if you ended up buying the phone and if it did lived up to the "no-laginess" expectations. The original galaxy s was very disappointing in this regard.

 

The OP hasn't visited this site since shortly after posting, I'm afraid.

 

What a leecher!

 

While we're on the subject, though, I must say my GS2 never had any lag through the time I have owned it, from the original GB through ICS.

However... now that it has been upgraded to JB it lags! :-(

 

^Have you wiped cache and data after upgrading?

 

Thanks for the answer.

 

@rpgmaker

I'm NOT the original poster. Just someone who picked up on the subject today.

 

Yep.

 

When do you experience lag? When I was on JB, I was only experience lag when I open the Widgets Screen on TouchWiz UX as I have many widgets(Blame UCCW. :v )

 

I know, but I thank you because this thread went from "no lags at all" to "lags in certain situations" and that makes the answers more nuanced than they were originally.
