Hello, I have some problems with my gio after upgrade it to 2.3.3 gingerbread with kies. It seems faster, battery can hold longer, but I have 2 very annoying problems. After I press the power button or home button when screen is off the screen unlock display shows only after 1-2 sec lag. I also have this lag when I would like to finish a call, when I put the phone away from my face there is a 1-2 sec long lag while the screen displays. I have already found probably its a bug with 2.3.3, but I want to ask you if it can be solved some way, or if it cant be solved, then how could I downgrade back to froyo. Thanks in advance.
