"you have to boot into recovery and wipe data or factory reset..

remove the battery and wait for some seconds then insert the battery again

hold volume down and power button together until u see a recovery menu, then choose wipe data/factory reset us volume down/up to navigate .. then restart when done..

WARNING!personal data Like SMS/MMS/Contacts/Apps/call history .... will be gone for good if you need those then consider taking the phone a pro for backup..

I had the Blu 4.0 star, and the brand itself is pretty bad :/ its a cheap brand, and I had that problem, and exchanged it, and the problem came up again :/ factory reset worked for a while, but it is a problem that will happened again and again. I would suggest a new phone.
