Very confused. I remember I installed an app call name announcer. First it worked but after few minutes this problem has risen.NEED UR HELP pls do reply
If the call name announcer did in fact cause a crash, try removing that app first, and have someone call you again. If it is still crashing, follow @Firelord's advice, clear the data and cache of the phone app, and perhaps try turning the phone off and on again. 

Lastly, if you are STILL getting this problem, try doing a factory reset. If THAT doesn't fix the problem, go back to wherever you got the phone and ask for a new one.
