Hello all, I'm wondering is it possible to downgrade firmware from ICS 4.0.3 to Gingerbread 2.3.4 using Kies? Since I have updated my Galaxy SII ( sim free version ) to ICS 4.0.3 I noticed that whenever I charge the battery, unit is getting hot ( on the left side back of the phone ) and also battery drains much faster then before ( which never happend while it was on Gingerbread 2,3,4 ) also I found that screen is not responcive as it was! Sometimes take couple times to understand that I am pressing certain menu or icon on screen, strange but it's true! As well as more RAM is being used now with ICS than with the Gingerbread. Also in the Setting Menu I noticed that some of the informations are not visible as they used to be, there so dark gray now I need extra effort to see them! Any advice or help will be appreciated Thank you!
