My BLU cell phone is blinking and keys are not properly functioning

press the home key, volume key, and power key hold for 10-15 seconds, when screen changes only release power key and continue holding volume key and home key. A menu will appear on your screen just follow instructions to do a reset. Good luck

the three function keys across the top are in cellphoneese referred to by the acronyms lsk csk and rsk. (left center right)
so csk is the large center joypad key.
press it ..try a few times until you see the 'press * to unlock' popup
then pressing * shows you 'keypad unlocked'
then i turned the silly feature off

Hi, samsung phones with blinking display is usually caused by the flex of the cell phone,.

It can be fixed.There is a common fault for all Samsung cell phones. there is a thread like object inside the phone called a flex that controls the functions on the keys on a cell phone when it's gets damaged, it makes the keys to malfunction. You will need to replace the thread like object which is the flex inside the phone for the keys to function again.

The flex of the phone is located inside the phone, it controls the functions of the screen an also the keypads of the phone.

The flex is a thread like object that is located inside the phone. To see the flex, you will need to disassemble the phone to get to the flex of the phone.
