Here's how ,,, if u can access ur settings ( I did this by hitting OK on sense has stopped white box, and quickly pulling down from top). Go to settings , scroll down to where it says APPS. Select that and scroll down again to SENSE HOME. tap SENSE HOME and u will see a bit that says STORAGE. tap the storage part and ull get clear data and another bit saying clear cache. Hit both to clear all data ect in sense home and then reset sense up on ur lock screen. So clear data and cache. Hope this helps, mines same phone and worked for me.
