I created a hot spot via network > wireless > use as hotspot.

Other laptops successfully detected the hot-spot,could connect and use it without any problem.

But no android phone could detect it.! I tried with many android phones but none could.(I found out that even an ad-hoc created in windows is not detected by any phone)

So is there anything wrong i am doing(rather i am not doing anything actually other than clicking on the "use as hotspt" button..but still..)? or is that the network cannot be shared with phones? and if not,how can i share it with phones?
