Samsung s583 mobile phone display application home screen process com.sec.android.aoo.twlauncher stopped unexpectedly. Please try again. What should I do? Why is this happening?

if your mobile phone prompts "the process has ended", suggestions are as follows: 1. turn it off and restart. 2. Uninstall and delete the recently installed software. 3. If it doesn't work, please back up the data (contacts, text messages, pictures, etc.) in your mobile phone, and then restore the factory settings. If the problem still exists, please bring the purchase invoice, repair card and machine to the Samsung service center, and the professional after-sales engineer will help you test it.
