[AC Question]

I have a Samsung Galaxy S4 android phone on the Verizon LTG 4 network. Recently, my eleven year old daughter grabbed my phone by both sides while I was driving and with whatever buttons were pushed, the whole android reset and I lost everything, including my calendar entries, except most contact entries. I am resetting things again and the emoticon issue was something I changed before but I forget how. Can anyone in plain English help me with my question above? Does anyone know if I can recover files from apps? Some apps I reinstall still have contacts like KIK, but apps like "s" memo wiped out all of my file notes. Thanks for any advice.
