i bought the ace 3days back. till now i haven't used wifi and dont have the mentioned problem.
but i am having a different problem.
my phone restarts randomly. It has happened 3-4 times till now.
What happens is this: screen seems to become unresponsive for say 4-5 seconds and then i see the samsung logo glowing on and off (which happens in the last stage of normal boot). Seems sort of a QUICK reboot. Anybody else having this problem?
