Lost all applications, phone contacts, SD card data, app data...

[VaishnaviK30]

One morning I wake up and found my phone switched off. I thought the battery was drained out and tried charging it and switching it on. It did not switch on, so I removed and put the battery back in place. Then, it did switch on, but I had to set up my gmail account again, and after opening the app drawer, I found that all my downloaded applications were washed out along with around 2000 photos, 5GB of songs and 20 videos. Basically, all my phone data and SD card data got deleted and all I have now are the default apps in my phone.
I have never ever took my SD card or phone back-up, as I was struck with the opinion that there is an auto-backup facility in Android phones.
I, now, am wishing there is some way to get back all the photos, songs and videos I lost. The applications could be downloaded again as there were just a handful (14-17) of them, but the photos, videos and songs are what I am concerned about.
Please suggest what to do.

I am not sure what could have happened in your case but to retrieve data from memory cards, the sites of Transcend & Sandisk have s/w which could do the needful.
