Before, I came Through Online Mining And I search For it Many Times,
and At Last, I Didn't found any Reliable,
I also Download Software apps In Playstore, Bitcoin Miners,
Also, Waste of Time.
And, The Worst case is It can Make your Phone Bootloop.
I feel the same old discussion coming up... Yes, there are apps out there that are able to do a sha256d hash of a block header while incrementing a nonce...

If you start reading the replys, the first reply actually indicating a hashrate was a guy who go ~6kh/s on a "Snapdragon 801". Other hashrates indicated were ~3kh/s, 2.7 kh/s,...
There are 7.600.000.000 people in the world. If they all had a relatively decent cellphone hashing at 6000 h/s (6kh/s), the total world population's hashrate would be 4.560.000.000.000 h/s
One single antminer S9 hashes at 14.000.000.000.000 hashes/second
4.560.000.000.000 / 14.000.000.000.000 = 0.32
This means that every person in the world should have 3 cellphones mining 24/7 with such an app to have the same hashrate as a single antminer S9
So, in conclusion, are there apps that can mine BTC... Theoretically, yes, there are apps that mine bitcoin. It's also possible to write an excel sheet that mines bitcoin, or you can mine bitcoin using pen and paper... However, in reality, the odds are so small i personally think it's better to say such a thing is impossible. If you tell people there are apps that mine bitcoin, it will only inspire them to run such an app, burn a lot of power, burn their phone, get nothing in return. By saying it's impossible, (hopefully) you don't give them crazy idears.
