iPad's core apps crashing!

So, I was browsing with my iPad, looking thorough websites, and when I was just about to tap an opened tab, it crashed! I thought it's not really a big deal, so I run the safari app once again and did the same thing. After a few mins, it crashed again! And for some reason, it happened for more than three times. Worried, I went to genius bar and told them what happened. The guy over there told me to at least do a weekly restart, just to clear out the history whatever, and I followed as what he said. Few days later the same thing happened, but this time I did the exact same thing as he told me and did a quick restart. Everything went normal, and the next day it CRASHED again, and now with the settings and photos apps.

So i was wondering what is what is really happening with this. Anybody experiencing the same things as me?? It's not really a pleasant thing to keep having the apps crashing and do the restart every single day.


Any help would be appreciated :) Thanks
