How to recover my files from memo and mobilse note after format factory? I have Samsung galaxy s plus i9001. i have format factory my phone recently but i had some important notes in memo and mobisle Note and i didn't backup them before formatting, is there a way to restore them? i think they were stored in system storage.

i have a full copy of my usb storage, but i don't have copy of system storage, and i just need memo and mobisle note data, is there any copy of them in usb storage?
I think you cannot get your data back...if you haven't created any backup. 
But For now you should download some apps and create backup for future use.. All these apps are available on Google Play.
