Wierd phone crash
I got a new samsung galaxy s2 a couple of days ago and was playing around with the lockscreen settings. I ticked the weather one and locked and unlocked the phone to check it out. It showed the homescreen instead of the lockscreen then the screen got unresponsive and then kept getting 'Tw launcher has crashed'. The only way to fix was too hard reset the phone. Is my phone faulty? Is there a fix?
Ps. Running android 4, no roms etc.
