I'm using galaxy gio s5660, After official update(2.3.3) from kies my phone is now completly unusable. There are lots of problems with my phone now, I'm really mad and about the destroy my phone and upload the video to youtube.. First of all, wi-fi crashes frequently, swype and a lot programs doestnot work properly, home button always takes screenshots, and recenlty, my phone start to shut down itself and wont open again if not pullling out battery... I contacted samsung - turkey, they answered me, "use kies and update your phone".. Sorry samsung but i hate you because you put clearly untested android images to kies, offer it via kies and not having any recovery... Additionally, behave me like i'm idiot. Now I hate you.
