Hi, I need help with a Galaxy Ace, Message "Sorry the application Samsung Home (process com.sec.android.app.twlauncher) has stopped unexpectedly. Please try again." with a box at the bottom "force close" which when pressed, shuts and reopens the same message. nothing else will operate. Switched it off, removed battery, removed sim, took it back to Vodaphone, who tried to reboot. They advised they need to send away for repair (10-14 days) anyone any options?
