When phone get charging from outlet, I want phone to power up
automatically without hitting any power button. (Not Working with wall
Socket, but working when connected to USB cable via Laptop).
You can only achieve this by modifying your phone's OS files. Basically there is boot script/binary at /system/bin/chargemon which you can replace with a script that does nothing. Do it at your own risk because this may result in the device being damaged permanently. Also, Manufacturer warranty will become void.
