Lag on system after Jellybean update.

Hello,

I updated my GSIII to Jellybean the day it came out for T-Mobile and after the update I noticed that there was some lag on the phone.

The lag is mostly going on in the samsung keyboard when I text or type out anything on the phone. It's also happening in some closing and opening of apps, but that doesn't matter to me as much becasue I mostly text on my phone.

Have any of you guys noticed that too?

I went in to the store and they basically accepted that there is lag there, but said that they cannot do anything about it. I have to wait until another update is put out. :c.
