I am new to the Android family. Maybe someone here can show me how to debug the following problem I have with my Android enabling and keeping the wifi switched on. I have myself a Samsung Galaxy ACE s5830 which I got just few days back and had found this problem where the phone just displayed error while switching on wifi. I then restarted the phone and found that wifi was working fine. After this I began noticing that the phone occasionally (two or three times a day) got hung up with a blank screen while the keypad is locked. This happens while the phone is getting charged and during idle time. When I tried unlocking the keypad, the phone do not respond. I would then have to disconnect the battery or press and hold the power key for 10 seconds to bring my phone back to life. However, I can see that if I switch off wifi, the phone does not get hung up in this manner. I appreciate any help to get this issue resolved. What I basically need is to always enable wifi at my home so that I will be connected at all times.
