Description.
when u switch on your phone this welcome screen comes.

and after that nothing happens.but in normal cases phone starts eith followins screen preceeding.

Cause.
This generally occurs when you switch off your phone directly(by taking out the battery or holding down the power button.why? because your phone is trying to read some instructions from the memory card but is incapable to do so due to your previous activity.

Fix is really simple and uptill now you have probably understood what to do.just take out your memory card and now switch on your phone with memory card uninserted.the phone will start normally.now insert your memory card with phone switched on. now you should uninstall any wnwanted software from your memory card(if there is any) and woohoo, the problem is solved.
