can't find the contacts icon??

[AC Question]

My phone suddenly restarted then the contacts icon disappeared. I have to open it from settings>apps>contacts>launch
I restarted the phone again but still, nothing.
And also now some apps have 2 icons????
There are 2 facebook icons and 2 whatsapp??

My phone is Innjoo fire plus 3g. Android 4.4.2

Welcome to Android Central! Try wiping the cache partition: INNJOO Fire2 LTE - Recovery Mode - HardReset.info. Those steps will hopefully work with your model.
