well actually there is a mining app for mobile devices called "Minergate". Well actually it's not that profitable to be honest. But, yea it may depend on the mining dificulty of that specific coin. Me personaly im mining bytecoin with 14-30 Mgh/s wirh my Samsung note 4. I would say again. It's not that profitable. 

Its defintely not recommended to mine on Mobile, Coz of heating and chances are of blasting, they are not built for mining, since many system apps running simultaneously and so risk is more of damage rather than earning. also its not profitable.

Well the idea looks great but I don't know how it could work. Most people uses smartphones, but they are not that great. They don't have that much processing power, they go out of battery way to soon if you actually give them use, and internet it still to expensive unless you have access to WIFI.
I don't know how a mobile miner would make a phone completely useless from a mobility point of view (I guess that you would probably have to leave it at home, plugged to some wall and using wifi)

the main issue with this concept is scalability, at the end of the day there's a lot more smartphone users and people willing to dedicate their resources to a network like this then there are miners or even bots on a botnet for mining... unless you leave the difficulty set in a way where it doesn't retarget (which would be very bad economically for the coin) it would never scale due to the rapid use of the network the only person who would profit in the end is the largest coin holders at the end of the retarget that finally makes it no longer viable for a smartphone to mine.

Mining on a mobile phone would be a good project, and would be something I would invest in.However it's just not feasible at the time due to the constraints of a mobile phone. I think in the future it there will be a project that truly allows us to be able to mine on the mobile phone.

This is the reason for which I just do not even think of mining on mobile, computer etc. The usage, power etc for such things is not perfectly fit and must be avoided. Because there would be hardly anything in return you will get it as against the time and money you would be investing like mobile phone continuously charging, its life will become smaller as compared to normal use.

You can use the freebitco.in browser mining on your mobile phone to do mining, however it is not good for your battery and the rewards are very low, so I don't use and I am not interested in mining on mobile phones

Dude, I'd be all over a coin like that, except I have a very strong feeling that the altcoin market right now is as saturated as it gets.  But I'm yhe kind of person who's so addicted to crypto that I still use faucets even though I know they're a waste of time.  But if I could mine an altcoin while I'm at work and have access to wifi?  Hell yes I'd do it.  Too bad you can't do that with bitcoin or some of the bigger name altcoins, like doge.  I'd be mining in a heartbeat.

I will be seriously interested in using my phone to mine coins and make money through it. I have tried to go through comment people are making on this thread but no one provide a good link or how we can actually mining coins through android or iOS application.
